Hi all!
As many of you might already know we have gotten a HTC Magic here in Scandinavia without support for netfilter and iptables. I've been trying to recompile a new version of the kernel on my x86_64 Archlinux box while adding these lines to the .config which I exported from my rooted phone:
Code:
CONFIG_NETFILTER=y
CONFIG_IP_NF_IPTABLES=y
CONFIG_IP_NF_MATCH_STATE=y
CONFIG_IP_NF_FILTER=y
CONFIG_IP_NF_TARGET_REJECT=Y
I am a n00b when it comes to compiling, booting and flashing Android stuff and not really a git wizard either. I've downloaded the source, cross-compiled it with my new .config and tried booting it with fastboot only to stare at the HTC logo for 15 minutes before giving up. I suspect that I have probably failed doing the right thing at more than one step in the process but have troubles finding a full guide for Android kernel hacking and loading on the web. I am not even sure if I really compiled the 2.6.27 version used in the daldroid build I have on the phone instead of the latest version in git.
I will provide the step-by-step details below.
1. Downloading and installing the CodeSourcery Cross-compiler from
HTML:
http://www.codesourcery.com/sgpp/lite/arm/portal/release858
2. Downloading setting up the android source code:
Code:
git clone git://android.git.kernel.org/kernel/msm.git
git checkout --track -b msm_htc origin/android-msm-2.6.27
git checkout -f
(here I noticed that the checkouts did not seem to download any extra code, is that expected?)
3. Setting up the cross compilation in the Makefile.
Code:
CROSS_COMPILE=../arm-2009q1/bin/arm-none-linux-gnueabi-
4. Using my .config when running make like this:
Code:
make zImage ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
(a few additional options not present in the .config-file need to be manually specified before the build starts)
5. Extracting the ramdisk from the nordic daldroid boot.img:
Code:
split_bootimg.pl boot.img
5. Trying the new kernel with the daldroid ramdisk:
Code:
fastboot boot arch/arm/boot/zImage ../../boot.img-ramdisk.daldroid.gz
creating boot image...
creating boot image - 1634304 bytes
downloading 'boot.img'... OKAY
booting... OKAY
6. Fail
I would really appreciate some help to get this going. How can I confirm that 2.6.27 was really used? What other gotchas I have forgotten about?

Hmm, unfortunately this option is already set to true.
Perhaps it is mainly a fastboot problem. I dunno.
maybe but why you dont try to make a boot.img and flash it?
did you set the system type to msm? it is important.
copy here your .config, maybe we can try to see if something is wrong or you can do this.
Code:
make ARCH=arm CROSS_COMPILE=../arm-2009q1/bin/arm-none-linux-gnueabi- msm_defconfig
for do a default msm .config.
For what I've seen, you're not making a kernel+ramdisk image, but loading them both splitted. Maybe you're missing the command line parametters?
Also, you can patch the kernel code to make it light up one of the leds so you can know if at least the kernel is actually booting or is getting stucked somewhere. To make this, you can patch, on board-sapphire.c, the init function:
Code:
static void __init sapphire_init(void)
{
int rc;
printk("sapphire_init() revision = 0x%X\n", system_rev);
/*
* Setup common MSM GPIOS
*/
config_gpios();
msm_hw_reset_hook = sapphire_reset;
msm_acpu_clock_init(&sapphire_clock_data);
/* adjust GPIOs based on bootloader request */
printk("sapphire_init: cpld_usb_hw2_sw = %d\n", cpld_usb_h2w_sw);
gpio_set_value(SAPPHIRE_GPIO_USB_H2W_SW, cpld_usb_h2w_sw);
[] INSERT HERE:
gpio_set_value(SAPPHIRE_CPLD_LED_BASE+XX, 1);
Where XX is the led number you want to enable.
Any progresses ?

Yeah, that could be a problem. I was under the impression that fastboot built the boot.img itself before transfering the kernel to the phone.
Interesting test with the leds. I'll check it out if I don't solve this.
I'm working on the exact same thing. can you contact me via im? pm for my screen names
I think that HTC patched some things in that are not available in the source tree... So I doubt that you'll be able to get a kernel running build from source. If you do happen to make it run let us know

I would not be suprised at all if that was the case. However, since the Linux kernel is GPL, such patches, as I understand it, also need to be under the GPL and made available upon request. Is there a public HTC source tree anywhere?
And btw, how can I fix the "recompile" misspelling in the title of this thread? It is driving me insane
This might be a very stupid question, but here it goes:
Shouldn't it be possible to build all the extra netfilter/iptables support for the vanilla 2.6.27 kernel as modules and insmod them when running HTC's kernel? Or will that result in swift and horrible death?
i don't see why it wouldn't. we wouldn't need the source for htc's kernel then, right? just figure out how to build the modules? isn't that kind of how proprietary video drivers work for linux?
EDIT: Modules will work, that is certain. A little googling confirmed that's how wlan and such work (on Android)
EDIT 2: It seems like there is .config for the kernel on the phone that can be used with the standard 2.6.27 kernel source to build the android kernel.
EDIT 3: found the kernel here http://github.com/zhoukejun/android-2.6.27-yf255/tree/master

I wonder if access to the kernel can help with the Bluetooth problems in the Hero ROM?
Bump!
Is there any news about iptables on PVT 32A based sapphire?

Well. The kernels that we successfully have built by cross-compiling refuse to boot. Looking at the config.gz that the phone exports and trying
Code:
make oldconfig
we have learnt that HTC has a lot of parameters specified for code that appears not to be in the standard android 2.6.27 kernel source tree. We would be very very happy if someone around here could point us to the repository holding HTC specific patches and code for the Magic/Sapphire.
Based on http://www.mail-archive.com/[email protected]/msg00442.html , it seems we need to find the source of the android-msm-htc-2.6.27 kernel.
Which don't seems to be public.

But it has to be made public if requested. That is essence of the GPL.
i emailed them a while ago. i also talked to someone who has gotten his own kernels to boot but on the dream dev phone
Hi ,
I have a Haipad M701 with me,
It is having this config:
4G Memory
Telechips 89xx board
Android 2.1-update1
MID-1.1
Kernel 2.6.29
I am trying to make a external USB fingerprint reader work with it.
The fingerprint device driver source was obtained from the vendor.
To enable the device i need to cross compile the fingerprint drivers.
But before i cud do that, i upgraded the firmware to Android 2.3(gingerbread) which is available in haipad.net(*w/o taking a backup*)(that is kernel 2.6.35).
Now, i am not able to cross-compile driver cos i took the kernel source (for 2.6.29) which telechips publicly opened to public.
So, Right now, i need the old Eclair(2.1,2.6.29) firmware, can anyone provide me that?
If not, is there any other way to achieve the cross-compilation?
In the meantime, i downloaded kernel source from android.com and branched to 2.6.35 which is the kernel version on device.
I compile the kernel and then cross compiled the fingerprint driver.
It compiled w/o any issues.
But when do a 'insmod', i get error:
Code:
mod_usbdpfp: version magic '2.6.35.7+ mod_unload modversions ARMv5 ' should be '2.6.35.7-tcc mod_unload ARMv6 '
What could be the issue here?
You have two problems:
First on the tablet, copy the file /proc/config.gz out on your build pc.
Extract and copy file to .config in the 2.3.35.7 source.
Now you are ready to configure the kernel sources that you compile the vendor driver against.
do make menuconfig;
Fix problems:
1: wrong name of kernel.
Insert "-tcc" in general setup --> Local version.
You seem to have a "+" now. I do not know how you got that. If it is not in the kernel config, look in the Makefile in the root folder. The version is in the top. Make sure the 4th version line just says ".7" - no more.
2. Wrong system type.
You are compiling the modules for an Armv5 instead of Armv6. Go to Arm system type and choose Samsun S3C64XX. That is an Armv6.
The selector might look really strange. If that is the case, scroll to the bottom and scroll back up (now names appear one at a time), until you see the ()amsung S3C64XX.
Configure Makefile for crosscompile.
Now do a make dep; make modules.
Now you can compile the vendor driver against this source and get the correct module. Use modinfo modulename.ko; to see that the name and type corresponds to "'2.6.35.7-tcc mod_unload ARMv6".
I have just done this (for an usb net driver), and the resulting driver crashes the tablet So even if you can get a module build and loaded, it might not work because the system architecture (S3C64XX) is not really correct. In that case we really need the telechips 2.6.35.7 sources to build correct module.
But try it out, and good luck!
Thanks for the suggestion, xdamala.
I will try it out today itself and let you know
@xdamala,
I had to do 'make s3c6400_defconfig'
But, Now i get this error.
Code:
mod_usbdpfp: version magic '2.6.35.7-tcc-g67bb0cf-dirty mod_unload
ARMv6 ' should be '2.6.35.7-tcc mod_unload ARMv6 '
I dont know how the 'g67bb0cf-dirty' gets added.
Each time i edit 'include/config/kernel.release' which contained that text, it automatically is updated on running 'make'.
Any idea??
I am not 100% on how the version string is constructed. But I think it is created from the top 4 lines in Makefile and the string you set in configuration.
I should not be necessary to do that s3c6400_defconfig. It is probaly what changes the string. I might have told you the wrong order of things in my other answer. It is important to set up Makefile first.
Do the steps (in order):
Start with clean 2.6.35.7 kernel code
edit Makefile in kernel root folder
Check version number in top
edit cross compile section to:
ARCH ?= arm
CROSS_COMPILE ?= ../../arm-eabi-4.4.3/bin/arm-eabi-
#or whatever fits your compiler. Note that this android tree gcc 4.4.3 is the one running M701 kernel is compiled with, so I prefer to use the same.
extract tablets /proc/config.gz to .config in root of kernel source (to remove unnecessary modules)
make menuconfig;
set -tcc in local version
choose S3C64XX system type
Exit (Save)
make dep ; make clean ; make modules; #Note you do not actually build the kernel, only modules.
In the Makefile from your driver there probably is a section something like this:
KDIR = /lib/modules/$(CURRENT)/build

@Xdamala
Code:
mod_usbdpfp: version magic '2.6.35.7-tcc+ mod_unload ARMv6 ' should be '2.6.35.7-tcc mod_unload ARMv6 '
Still the plus seems to be issue.
I checked in the main Makefile there is no '+'.
But in include/generated/utsrelease.h, there is
Code:
#define UTS_RELEASE "2.6.35.7-tcc+"
Well I use a kernel from kernel.org, not from the android tree.
Might be the reason for the "+".
I do not think that it makes any difference in this case.
Try with the kernel.org one. If it works it works, if not we might try to look at that "+"
By the way if all fails you can reinstall 2.1 on the tablet and build against the 2.6.29 kernel released by telechips. It should work.
The downside: 2.1 sucks, and usb in general sucks a lot on M701 2.1.
See my posts here:
http://www.androidtablets.net/forum/groups/11-haipad-m701-m701-r-d129-just-ordered-g10-haipad-m701.html.
In that case go to telechips kernel source:
make tcc8900_defconfig
make menuconfig. Exit + save.
make modules.
Then compile your driver against these sources.
Your driver should then work (this time we use the correct system type), but usb is quite bad on 2.1. So if I was you I would try a lot to make 2.3 work first.

Thanks xdamala, thats what i needed, will check it out and let you know of the result tomm.
I will warn you that 2.1 comes with its own problems when it comes to usb.
Attach the device directly. Do not use a hub.
xdamala,
Method 1: Compile kernel source of 2.6.35.7 from kernel.org - Success
insmod driver.ko installed w/o any errors.
But, it seems i would need a power source for the fingerprint reader.
i dont think currently the Haipad support that mode.
Method 2: Flash(downgrade) m701 to 2.1 and try with the public kernel source which telechips have released - Failure
The FWDN program gives CRC check error while loading tcc8900_mtd.img.
Maybe bcos of corrupt download or the Haipad i have is a 4G memory one.
Which u think wud be?
Even if i accomplish providing power to the fingerprint device, i would need the C++ sample provided by the fingerprint vendor to be cross-compiled.
Otherwise, how can i test if the device works?
How to do that??
Hi
I did not see your post because it now came as page 2.
The tablet should provide some level of power to the reader. If you use the white converter cable that came with the tablet, it should tell the tablet to provide power (USB On The Go, see Wikipedia). It works with memory sticks and even hard drives. But I do not know if it is enough for that reader.
With 2.3 firmware you could use a power hub to give power to reader (still use white converter cable between tablet and hub). Do not use hubs on 2.1.
To check if tablet recognizes reader do this:
adb shell:
#dmesg -c
#insmod driver.ko
#dmesg
--Insert reader in usb
#dmesg
The output of dmesg should tell you how the kernel reacts when driver is loaded and reader inserted.
You can cross compile c++ code using same compiler as for the kernel. But you will have to compile program/libs statically, since android does not have the C++ libraries.
You can probably achieve this by putting a static keyword in a Makefile.
Also you need to direct the gcc to point at the cross compiler.
An other approach is to install Debian on the tablet inside an file image. I have done this. It is very nice. It gives you a complete (non graphical) Linux system. Compiler, libs and all. Also lsusb and other useful tools.
It is much easier to make Linux programs work like that.
But this Debian will run inside chroot, and cannot see the android system.
I used this tutorial:
http://www.saurik.com/id/10
However I used a bit different approach for starting up Debian system (using Debian own rc scripts).
If you can make the Debian Image, I will be happy to provide you with my scripts to manage it.
I do not know why you cannot install 2.1. It was the one you got fro my URL?
I just see now that Haipad has released a brand new 2.3 this night.
Do not attempt to load it. Last one did not work unless you had the very new tablet. I will try this new one tonight.
What is this project with the fingerprint reader? Tell me more.
Thanks xdamala,
Ya if it is possible, i would surely like to have a Debian on the pad.
I am just exploring things on it, so that we can have a external device work on the pads.
Let me check this url and will let you know
http://www.saurik.com/id/10

Click to collapse
Ya, if you can help through the process, i will gladly accept it
Also, i didnt get any cable with my pad.
That was the first of issues. Had to buy it separately.
I had done the dmesg check as you told, but it didnt give any noticeable output.
The 2.1 firmware link that you gave, throwed a CRC error. what to do?
if you get a crc error on firmware it is probably because its the wrong firmware.
There are several different versions of this tablet so it can be a bit tricky.
This firmware is for a M701-R 4GB HY
There is 2 GB and 4GB versions. You have a 4 GB right.
There is HY and non HY versions (type of nand memory).
There a re with and without remote control. That is not so important.
I think any mix of the above is possible.
How to figure out if you have a HY version:
Insert usb to pc and enable usb storage.
If nan memory is shown as 3,08 GB (I think) it is an HY.
If it shows less (2,7 GB Ithink) it is a non-HY.
Determine your version and we can see if we can find a FirmWare for it.
Anyway I think you should keep your 2.3 for now. It just is better for USB.
What is the filename of the rar file with 2.3 rom you installed, and where did you get it from? (this might help me identify your tablet).
About usb cable. I now understand why you have no power on reader. If you read the wikipedia article about USB OTG (wikipedia) you will understand that the tablet is in slave mode and will not provide power and probably not talk to devices.
Also see here: http://www.maxim-ic.com/app-notes/index.mvp/id/1822
Can you get a memory stick to work?
You need something like this:
http://www.amazon.co.uk/Host-Cable-ARCHOS-Internet-Tablet/dp/B004TJC1IM/ref=sr_1_3?ie=UTF8.
It will short the correct pins in the mini usb plug, telling the tablet to be master and provide power.
It is possible to fix a cable yourself but I will not recommend it:
http://www.youtube.com/watch?v=COkLEJGo6vo&feature=youtu.be
I am a bit surprised that loading the driver produces no output in dmesg.
But if the tablet is not in host mode, it is not surprising that no output comes from inserting the reader. The tablet is not responding to it since it is in slave mode (like connection two usb sticks. Nothing happens).
I can not help you through the Debian. I used the tutorial I already linked.
If you do the same and add my scripts you should be able to make it work.
Alternatively you can get my Debian Image, but it is 1 GB file, and I need to clean out personal stuff and passwords.
Hi xdamala,
Ya, it seems to be a non-HY, cause i have around 1.4G space in nand
The file i downloaded was M701_2.3.rar, which i downloaded from haipad.net
I did buy the cable like u showed in amazon.com link, using that only am connecting the reader to pad.
And No, a memory stick also is not getting detected on that cable.
Attached that cable image.
Hi xdamala,
I have started creating the debian image, can you tell how you use the rc scripts?
Also, were you able to find the 2.1 image for M701 non-HY?
PS: I got the clockword mod recovery image from here http://androtab.info/telechips/firmwares
I used the one marked "Haipad M701 GB ROM 4K"
It worked for me.
Hi
Several things:
1: I think you have an 2GB version (non HY), not a 4G version.
2. It seems like the cable you bought is not correct. It has to be a HOST adapter/cable. Since nothing works with it I think what you have is just a male min-usb to female usb. It is not enough.
3. About Debian image. Which version of Debian are you using?
By the way I found out how to get rid of the "+" when using the Android kernel source. Move the folder .git to git. This will break git usage (unless you move it back). But it removes the "+" in version string.
Using Android kernel source might be better than stock kernel source.
Hi again,
1. Its a 2GB?? Oh but when i followed this link (translated it english)
Code:
http://www.inzipad.com/thread-334-1-1.html
My result was 4096, so i thought its a 4G one.
2. Oh. Then i will try to buy then one u have recommended.
3. I have dropped the step of building a Debian, cause i have a android application running and the input from the usb reader has to be sent to that application. So, I have to make it work natively on Android.

You have two problems:
First on the tablet, copy the file /proc/config.gz out on your build pc.
Extract and copy file to .config in the 2.3.35.7 source.
Now you are ready to configure the kernel sources that you compile the vendor driver against.
do make menuconfig;
Fix problems:
1: wrong name of kernel.
Insert "-tcc" in general setup --> Local version.
You seem to have a "+" now. I do not know how you got that. If it is not in the kernel config, look in the Makefile in the root folder. The version is in the top. Make sure the 4th version line just says ".7" - no more.
2. Wrong system type.
You are compiling the modules for an Armv5 instead of Armv6. Go to Arm system type and choose Samsun S3C64XX. That is an Armv6.
The selector might look really strange. If that is the case, scroll to the bottom and scroll back up (now names appear one at a time), until you see the ()amsung S3C64XX.
Configure Makefile for crosscompile.
Now do a make dep; make modules.
Now you can compile the vendor driver against this source and get the correct module. Use modinfo modulename.ko; to see that the name and type corresponds to "'2.6.35.7-tcc mod_unload ARMv6".
I have just done this (for an usb net driver), and the resulting driver crashes the tablet So even if you can get a module build and loaded, it might not work because the system architecture (S3C64XX) is not really correct. In that case we really need the telechips 2.6.35.7 sources to build correct module.
But try it out, and good luck!

Thsi really works thanks for that
I've got this side project going where I've decided to try to modify the stock kernel for my GT-I9000M.
I'm a Gentoo linux user and have cross-compiled kernels for embedded systems with or without initramfs and modules successfully many times. Rather than just grab and flash the latest mod from the net I want to understand exactly how to create my own.
I already have access via a chroot to a working Gentoo install, however that runs in a sandbox inside android userland, which can be irritating to say the least. I'm already able to create binaries for armv7a on the phone itself, which is a time and power-consuming novelty.
I setup a development environment on my main computer and made sure I could create working binaries for the armv7a.
I backed up all the bml partitions on my phone.
Next, I made sure I could access Download Mode and experimented with Heimdall until I was satisfied I was able to recover from any bad kernel flashes.
I altered the first boot logo in param.lfs with dd, but that's a whole other story.
Next, I downloaded Samsung's source for Froyo and followed the instructions to create a zImage.
aries_eur_defconfig selects the FM radio module and the Samsung TV out driver which are broken. No problem, I figured I could check that out later so I disabled those options for now. it compiles! great! But it didn't boot. I turned to the internet for ways to solve the problem.
There was a lot of conflicting information. I ended up trying a lot of different approaches, modules, firmware, version info, kernel command lines, fbcon... well I messed around.
Some time later, I find myself happily booting with my own kernel. The bootloader displayed my custom logo in param.lfs, but fbcon didn't work and I got a stock samsung gt-i9000 logo before android booted up! The phone worked, wifi worked, bluetooth worked, it was awesome (for 2.6.32.9 that is )!
So, great! Except I got overconfident and cocky. I made a slew of changes trying to get fbcon to work and to top off the evening I overwrote my working zImage with a broken kernel (without a backup of my working custom zImage or .config). I still have backups otherwise of course and haven't lost the functionality of my phone in any way, but now I'm just irritated.
Anybody else working on compiling from source on the GT-I9000M?
I pressed ahead and tried to recreate the conditions that got me a working kernel and as of yet I've been unsuccessful Luckily I've got a kmsg from the kernel when it booted. I can see the kernel command line on the custom kernel that booted was simply "console=ttySAC2,115200" although I do recall trying different values for init= ... The default init in the sources is /linuxrc which doesn't exist in initramfs.
There are also settings for the kernel command line and version information in arch/arm/mach-s5pv210/include/mach/param.h
Is there a known good method to compile from Samsung's sources?
I unpacked a known good zImage, played with it's initramfs, repacked it and it boots just fine.
I've tried again with a fresh copy of the gt-i9000 froyo-samsung branch:
- unpack initramfs from a known good 2.6.32.9 kernel
- make clean
- make aries_eur_defconfig
- make menuconfig, add initramfs, remove Samsung TV driver and FM radio module
- make
the resulting vmlinux is: ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, not stripped (I know, it's zImage not vmlinux but I'm just doing sanity checks)
I have a custom logo in param.lfs which always displays on boot. A second logo is compiled into the kernel, and I do see a change in the logo when my kernel boots (it shows GT-I9000 instead of GT-I9000M after the first logo). This leads me to believe that the kernel is booting... but the phone powers off after booting.
I've tried the recommended changes to default.prop to use adb to obtain the kmsg of the new kernel. This has not worked however, which could mean that the kernel doesn't get as far as initramfs.
the kernel command line from the kmsg I have from the one time that a custom kernel of mine booted is simply: "console=ttySAC2,115200 loglevel=4" . There's no mention of init, which I think should be init=/init although aries_eur_defconfig seems to think that init=/linuxrc is appropriate (linuxrc doesn't exist?) Regardless, it doesn't seem to matter what I specify for init.
Which leaves proprietary Samsung kernel modules. If they can't load, this could explain everything I'm experiencing. It isn't clear what specific version the proprietary modules are expecting.
Maybe this will help somebody else. I've got it working now.
Attached is my working config.
Hi guys!
Someone requested a tutorial on how to build the kernel source code, so I thought I might as well do it I'll give you a bit more information too.
Maybe this will kick start kernel development a little bit too. Who knows.
Anyway:
1. Set up your build environment as per this guide by AOSP here: http://source.android.com/source/initializing.html
This guide will be primarily aimed at Ubuntu, but it should be easy enough to do on other Linux PCs. Ubuntu is highly recommended. And don't ask about Windows.
2. Download the toolchains: http://code.google.com/p/rohan-kernel-evita/downloads/detail?name=toolchains.tar.gz&can=2
I've hosted both GCC 4.4 and GCC 4.6 (prebuilt) on my Google Code page. These are for Linux.
Download the toolchain package here: http://code.google.com/p/rohan-kernel-evita/downloads/detail?name=toolchains.tar.gz&can=2
Then un-tar the archive and extract it to your home folder so that the path to the toolchain directories are ~/toolchain/whatever-one-you-want
3. At this point you can decide which kernel source you want to download. There are really two sources.
The first choice is getting it from HTC Dev directly. This is good if you want to build your kernel for a Sense 4 ICS ROM. If you want to build for AOSP/JB, then scroll down below all the following HTC stuff.
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
To use HTC's source:
Go to HTCdev.com and make an account. Then download the source code for our device (I'd recommend the "One X" source under carrier "AT&T" version "2.20". Let the zip file download and extract it to your home folder (so the path is /home/user/evita-ics..../
To build HTC's source, run these commands:
Code:
cd ~/evita-ics-whatever_the_directory_is_named
export ARCH=arm
make elite_defconfig
Second command is saying what type of architecture we want (we are compiling for ARM processors, so we want ARM)
Third command is saying to make the default config for our device (whose hardware is codenamed "elite")
Then to build the actual kernel:
Code:
make -j# ARCH=arm CROSS_COMPILE=~/toolchain/arm-eabi-4.4.3/bin/arm-eabi-
In the command above, there is "-j#". Replace the "#" with the number of CPUs you have.
Ask me about it if you need help. That should be it! Let the build go and in a few minutes you should have a zImage file located at ~/evita-ics-..../arch/arm/boot. That is the actual kernel.
To test out the zImage (kernel), connect your device via fastboot mode and type:
Code:
fastboot boot /path/to/zImage
Combined with the ramdisk, thats what makes the boot.img file. Eventually if you want to distribute your kernel, you should use an installer that injects the zImage into the boot.img or combine the zImage with a ramdisk to make a boot.img. I can do a tutorial on that later on as well.
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
To get the "other" source:
This source is based off of HTC's source and includes other devices as well in it (the One S and Evo 4G LTE). Its good if you want to build JB AOSP kernels.
To download this kernel source do this:
Code:
mkdir ~/kernel
cd ~/kernel
git clone https://github.com/CyanogenMod/android_kernel_htc_msm8960.git -b android-msm-evita-3.0
This version also includes a number of optimizations and odd bug fixes present in the HTC version.
To build this second source, run these commands:
Code:
cd ~/kernel/android_kernel_htc_msm8960
export ARCH=arm
make elite_defconfig
Second command is saying what type of architecture we want (we are compiling for ARM processors, so we want ARM)
Third command is saying to make the default config for our device (whose hardware is codenamed "elite")
Then to build the actual kernel:
Code:
make -j# ARCH=arm CROSS_COMPILE=~/toolchain/arm-linux-androideabi-4.6/bin/arm-eabi-
In the command above, there is "-j#". Replace the "#" with the number of CPUs you have.
Ask me about it if you need help. That should be it! Let the build go and in a few minutes you should have a zImage file located at ~/evita-ics-..../arch/arm/boot. That is the actual kernel.
To test out the zImage (kernel), connect your device via fastboot mode and type:
Code:
fastboot boot /path/to/zImage
Combined with the ramdisk, thats what makes the boot.img file. Eventually if you want to distribute your kernel, you should use an installer that injects the zImage into the boot.img or combine the zImage with a ramdisk to make a boot.img. I can do a tutorial on that later on as well.
-----------------------------------------------------------------------------
The second option is also a bit better as it uses the 4.6 toolchain instead of GCC 4.4. HTC's source doesn't work with GCC 4.6 so it can't be used without changes that the second source has.

Thanks for your response, rohan. You are absolutely right: I was incorrectly attempting to flash zImage straight to the boot partition, and the error produced by flashboot was justified. I have since successfully "tested out" my compiled zImage by flashing it via "fastboot boot zImage" and it worked like a charm! I ported the modifications from sbryan's Blackout BeastMode kernel and I am now able to OC to 2106 MHz and UC to 192 MHz. It's been running solid for the past few hours at least
Of course, the kernel reverts back to the one stored in the boot partition after a reboot, and I want my shiny new kernel to "stick". I've done a bit of research on this topic and found some information about combining my zImage with a ramdisk into a "real" boot.img but have not yet been successful in creating a boot.img which does not bootloop after flashing it.
For example, I found an article on xda called Basic Kernel Kitchen for Minor Kernel Tweaking which points to a "kitchen sink" tool for creating a boot.img from a zImage and a ramdisk. My problem is that I don't know where to get or how to make a ramdisk. So I tried using the ramdisk from the boot.img of the ROM that I am currently running (CleanROM 4.5 DE) but just got into a bootloop. I've since been doing some yard work today so haven't gotten back to investigating further.
I also found another program named abootimg which can also produce a boot.img from a zImage abd a ramdisk, but when I tried it an error message about my zImage being "too big" was produced.
If it's not obvious yet, I am kind of fumbling around in the dark as compiling and deploying custom kernels is completely new to me! But this post was the most valuable resource I've come across in getting to this point. Thanks so much for writing it! I eagerly await your next article about creating the boot.img

Thanks for cleaning up the post rohan. I have a few follow-up questions/comments:
missing toolchains link -- the post says "Download the toolchains:" but there is no link to download anything... did you forget to paste the link?
official toolchain -- That's great that you uploaded the toolschains to save tonnes of bandwidth. The CM10 source was taking a VERY long time for me to grab. However, I imagine some people (like me) would prefer to get the toolchain from an "official" source. In the "evita_readme.txt" file of the kernel sources downloaded from HTC dev it instructs one to use the official sources from "git clone https://android.googlesource.com/platform/prebuilt". This is the toolchain that I used and it successfully built the zImage.
ko files -- I noticed in the ZIP file for Blackout BeastMode, in additional to installing the zImage it also puts a bunch of "ko" (kernel modules I believe) into the /system partition (eg. qce40.ko). Should I also be deploying .ko files from my build to the device?
Thanks!

official toolchain -- That's great that you uploaded the toolschains to save tonnes of bandwidth. The CM10 source was taking a VERY long time for me to grab. However, I imagine some people (like me) would prefer to get the toolchain from an "official" source. In the "evita_readme.txt" file of the kernel sources downloaded from HTC dev it instructs one to use the official sources from "git clone https://android.googlesource.com/platform/prebuilt". This is the toolchain that I used and it successfully built the zImage.
ko files -- I noticed in the ZIP file for Blackout BeastMode, in additional to installing the zImage it also puts a bunch of "ko" (kernel modules I believe) into the /system partition (eg. qce40.ko). Should I also be deploying .ko files from my build to the device?
Thanks!

Hey!
Sorry, set it to upload then got distracted Link posted
The reason why your boot.imgs bootloop is because there is a special ramdisk address that needs to be set when combining the ramdisk with the zImage, and most kitchens don't support this. You also need to set the address after setting the base value.
I will post a guide on how to make it a real boot.img whenever I get the chance.
I'm telling you people, Rohan is a BOSS. Most helpful dev I know.

I have the zImage thanks to your tutorial, but I want to know how to create the kernel zip, whenever you have time will be amazing if you can post a guide, I'm really looking forward to that guide, because i haven't been able to locate a guide that works

Hi guys!
Second command is saying what type of architecture we want (we are compiling for ARM processors, so we want ARM)
Third command is saying to make the default config for our device (whose hardware is codenamed "elite")
Then to build the actual kernel:
Code:
make -j# ARCH=arm CROSS_COMPILE=~/toolchain/arm-linux-androideabi-4.6/bin/arm-eabi-

This is the correct make for "other source" kernel.
Code:
make -j# ARCH=arm CROSS_COMPILE=~/toolchain/arm-linux-androideabi-4.6/bin/[COLOR="Red"]arm-linux-androideabi-[/COLOR]
Can you make a tutorial on how to insert governors into a kernel?
Compiling problem
Hey man,
Please help me I followed your article but when I try copile with:
make -j2 ARCH=arm CROSS_COMPILE=~/toolchain/arm-eabi-4.4.3/bin/arm-eabi
I got something like this:
/home/martin/toolchain/arm-eabi-4.4.3/bin/../lib/gcc/arm-eabi/4.4.3/../../../../arm-eabi/bin/as: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory
Thanks
UPDATE:
now its work
I went deeper and install lib32z1 with "sudo apt-get install lib32z1"... now its work
My device repositories are not available on github, But I got device tree and vendor blobs by making changes in similar device repo. That reference device's kernel's lineageos_defconfig is situated in htc msm8974 kernel repo. So how can I get lineageos_defconfig for my device, and which other my device related kernel files(.dtsi or any other) I have to push in htc msm8974 repo and get those files to make things ready for build?
Please help......
Specifications:
Phone: ASUS ROG 1
Model Number: ASUS_Z01QD
Android version : 8.1.0
Firmware: WW-15.1630.1907.98
Kernel Version: 4.9.65-perf
I have an ASUS ROG 1 Phone. It came with Android 8.1 and firware version WW-15.1630.1907.98. I took the kernel source code from ASUS site. Source code version: <new user on XDA hence unable to post the src code link.>
Was able to build successfully and flash to the phone. Rooted the phone following to that. The problem is that the wifi wasnt working after flashing the new kernel .
1. I checked the modules loaded lsod, from adb and it didnt show the wil6210.ko loaded.
2. I tried insmod /modprobe wil6210.ko and was constantly getting the following errors:
a. disagrees about version of symbol module_layout android kernel
b. required key not available .
c. No such file or directory.
3. I tried building the kernel with the SIG flags disabled in the .config file and flashed to the phone. Yet ended up getting errors like no such file or directory and required key not available.
Any help will be really appreciated.

You need to rebuild the Wi-Fi module against the source that you compiled then flash it. Alternatively, you can try building the Wi-Fi source into the kernel image but that is usually broken or you can force the module to load by whitelisting it in kernel/module.c (there are commits floating around that allow this) but it can open up a security vulnerability.

Thanks for your reply.
The source code I downloaded from the ASUS website, the wifi module code was a part of it. So whille building the kernel the module <wil6210.ko> also got built along with it.
So the wifi module did get built against the same source.
