Hi all. I'm trying connect to device remotly and get kernel debug. Two weeks i trying and make everything by google but now i couldn't understand why it want not work.
What i do:
1. Prepare USBtoUART with 1.8V and plug into headphone jack. And test him with terminals on host and phone - all is OK.
2. Download hammerhead 6.0.1.mr2 sources from android dev page.
3. Download kernel serial KGDB patch from github 'jduck' member (gist.github_com/jduck/caf1eddcd4c9ac27d818)
4. Compile the kernel and replace it with mkbootimg
last cmdline is
./mkbootimg --base 0 --pagesize 2048 --board 'LGE rev_11' --kernel_offset 0x00008000 --ramdisk_offset 0x02900000 --second_offset 0x00f00000 --tags_offset 0x02700000 --cmdline ' kgdboc=ttyHSL0,115200 kgdbretry=10 kgdbwait' --kernel /home/udroid/workdir/src/kernels/hammerhead/6.0.1.mr2/arch/arm/boot/zImage-dtb --ramdisk ramdisk.cpio.gz -o /home/udroid/workdir/imgs/hammerhead/boot.img

*without kgdbwait phone booting fine and waiting debugger connection by "echo g > sysrq-trigger".
5. Download and install Ubuntu 16.04 LTS (x64).
6. Install arm-none-eabi-gdb (7.10) from ubuntu repo.
7. PowerOn the phone, run gdb with kenel symbols.
what i have in log:
(gdb) set debug remote 1
(gdb) set serial baud 115200
(gdb) target remote /dev/ttyUSB0

Phone rebooting and trying again connect to debugger, but after connection it get NOT supported packets and reboot again. For test reason i just comment "goto kgdb_exit;" in gdb_serial_stub() but nothing changed. I try to see "qSymbol" in sources but again - nothing found, gdb_cmd_query() do not have code for processing this type of request.
Maybe someone can explain me - how to i can debug kernel in android systems? Maybe i need other patch for kernel sources? Please help me understand this.
Thank You.
**sorry for my english
maybe someone can tell about some forum/community where i can find peoples who understand something in kernel debugging in android?
Did you resolve this issue ?
Related
This thread to collaborate all efforts towards porting kernel 3.4.x on to the Galaxy 3. If any developers wish to help then please let me know and I will add you to the SG3 group on Github (provided you have proven yourself capable of helping by forking the repository and submitting a pull request of changes you have made - I won't just add people if they are 'learning how to develop for Linux').
Changelog
https://github.com/sg3/android_kernel_samsung_s5p6442/commits/s5p6442-3.4
I chose the Github commit system to be the changelog as there are so many things going on at once it would be impossible to keep up with, and I cannot be assed explaining it. If you don't understand then ask, but please don't ask EVERYTHING. Most of the answers will be 'It just does'.
I am trying to follow the standard process for committing to GIT by doing 's5p6442: change' or 'apollo: change' so it is easier to see what is being fixed and why we are changing it so people reviewing code have an easier job. I expect other developers to follow this as well. Pull requests made that do not follow this naming convention will be rejected.

Members
The following members already have full read/write access to the repository:
cdesai
hillbeast <- has UART
marcellusbe <- has UART
moikop <- has UART
tom3q <- has UART
As you can see I also listed who has UART (that I currently know of). If you also have UART then let me know and I shall add it to the list. Having UART will be a huge help as it means we can see what is going on.
Why Do We Need Kernel 3.
Easier updating the kernel to add security and performance boosts from mainline Linux kernels
More support for new versions of Android
Android 4.0 was built upon Linux Kernel 3.0.x and therefore expects kernel 3.0s APIs
Faster, more secure system
NO SAMSUNG MORONIC CODE
Because it's just better
Please let me know if you are interested (able to) in helping this cause. Please don't put your hand up if you can't dedicate your phone to this. This will result in your phone being out of action quite a lot while we are testing, and if you need your phone 24/7 then you're going to need to keep flashing back. You will also NEED ODIN. Flashing from CWM is not an option.

Things to be aware of
I feel these things should be mentioned as they are important changes that may disrupt peoples user experience on the phone.
Odin will not work anymore for flashing ROMs. It's as simple as that. We will no longer be using STL/BML/TFSR for interfacing with the NAND, and that is what ODIN expects to be working with: partitions in STL format. We simply will not support STL when this kernel is complete as it is closed source and will not function on kernel 3.x. We will be moving over to MTD which is mainline, and regularly gets updates to improve performance, reliability and in general to make it better.
Kernels will however be flashable from ODIN. This WILL NOT change. Kernels, modem.bin, Sbl and boot.bin will all still work from Odin. Data, system and cache will not.
I know this will annoy a few people, as it will disrupt me too as a developer and a Windows user, it's nice to be able to flash a ROM this way, but we're going to have to move towards distributing ROMs in system.imgs, or more preferably in update.zips.
There will be no support for Samsung Froyo/Eclair ROMs in kernel 3.x. The reasoning behind this is because Samsung ROMs want Samsung drivers and we won't be using any of them. We will be aiming to support CM7 and CM9, or generally any AOSP ROM, but not Samsungs proprietary ROM. You may think 'well why not make the drivers work for both', but the problem is not with making the drivers work, the problem is with the fact that a lot of these drivers were written for a kernel over 10 major versions out of date by now, and will not function on the new kernels APIs. If we try to make them work, it will make the kernel unstable and it's going to degrade the experience for the end user. As well as that, we don't know how half these drivers actually work because they are either coded so badly it's impossible to make heads or tails of it, or it's closed source and we can't find sources for it.
There are plenty of good custom kernels for Froyo, and I have heard word in the grapevine a few people want to make a custom Eclair kernel (not confirmed, and that is just rumours), but I will not be adding support for Froyo to kernel 3.x
Kernel 3.x will not allow us to work magic with the phone. Having a newer kernel won't allow us to make the CPU itself faster, we can't give it more RAM (or find more RAM in there). We won't be able to unlock more performance from x part. This is not a magical rebirth of the phone, this is just a major fix up of all the current issues we face with AOSP based ROMs on the phone. It will most likely make the phone faster, but we can't magically make it into a dual core or something like that. It just isn't possible.
I see a reserved post there!
And one more for good luck. Now you may post.
So many reserved posts WHOA!
could possibly add a guide to clone and build it
EDIT:
Btw, also add a note about the two branches on github
android-3.0 = android-common kernel from android.googlesource.com
linux-samsung = kgene/linux-samsung on kernel.org / github
+1! Yeah guys well done! Finally! Is it only me that I think that may we have a beta or final version of Gingerbread or (cross fingers) ICS if you guys port the 3.0 kernel for our phone?
Good to have a new thread now.....
All the best Mark & all the Devs in this project..
+1 Good luck!!
Good luck with this project
All the best.. Although this is gonna take much time still waiting patiently
I may sound like an ultra-noob here : But what is Kernel 3.0 ?
Google isn't help here
You could add this to the first post but only computer programmers will understand it, unlike me

Newer version of the kernel that will be completely built from scratch. tom3q did this on the Spica and it worked wonders, now it's time to do it to our phone.

I don't like kernel.org. They're hopeless, shown by their hacking last year and their slow recovery time, and then made worse for the fact that Linus Torvalds himself switched to Github.
This is what i wanted to see since long times now. I just wanto say thank you to all the devs for just trying

The error is not on /arch/arm/kernel/debug.S, it's on /arch/arm/mach-s5p6442/include/mach/debug-macro.S (Error caused by just putting Samsung's .32 code into 3.x I guess...).
Check out that addruart_current is defined a few lines before, and it refers to "adduart" which is defined at debug-macro.S (that's why before defining addruart_current, debug-macro.S is included).
And if you check debug-macro.S, you'll see that adduart is defined only with one parameter, when in debug.S it's used with two parameters. That's where the error comes from.
In order to fix this, you'll have to redo the debug-macro.S file so that adduart takes two parameters (IMO should be based in S5PC110 or Spica's (or maybe s5p64x0?) debug-macro.S).

you're using homebrew right? if yes, does it compile faster? in a word, ill grab my sis macbook pro !
BTW, which baseband are you gonna use for this kernel ?

I found uart pin on mainboard for debuging .
with serial usb cable pl2303
This is the red light only and unknown hardware found (the unknown hardware is in fact mtk usb vcom driver buth sony version ) if you try sp flash tool for mtk then it comunicates with de phone buth it needs some authentication file.
Help..

please share the uart pinout , thanks
Hi
Around for months ago I buy from Aliexpress "Merrii H4" board.
Then it was delivered, I try to use it... Connect power cord, connect VGA display, power on.... and see - nothing. For I wiil right at all, I see "wrong resolution" OSD message. I use my PHILIPS 223V display, I try to connect HDMI thru HDMI->DVI converter, see - nothing, and display "freezing" not answer to any button, POWER included.
I connect UART->USB converter and have a look boot LOG, it's right... I can read how system (android 4.4) started, I see info about screen resolution (800x480)
But... I want to do something else. I'm already try to communicate with merrii support... it is terrible... Hi talking with me, like I'm a stupid guy with no any skill and ... it is very very slow... Hi is answer to me two...three times per day, and him answer not helpfull.
NOW I'm already try to use PhoenixSuite 1.0.6, 1.0.8, 1.10 and PhoenixSuitePro 3.3.0, 3.3.4 to replace firmware, I can't do it, programm can't open iimages what I have...
sun6i_android_fiber-3g_v3.3_hummbingbird__TP_WIFI_BT_TV-IN_VGA_USB_OTG_3G_TCARD_RTC_OK_测试.img
sun6i_android_fiber-3g_v3.3_hummbingbird__LCD_TP_WIFI_BT_USB_OTG_CAMERA_3G_GMAC_TFCARD_RTC_ok_出货.img
what I do: run programm, press the UBOOT button and then plug USB cable, nothin is action with PS, and PSPro say "bla bla bla.. don't connect any device before ..."
When I try to open IMG file in PS, programm say "can't open Image"
When I open IMG file in PSPro and press START button after, nothing
Have I any luck to Sombody can help my situation?
I want to use my board with SOMETHING display for the begin.... And after I want to use it with 12.3" screen in my car.

I did some probing and found the UART pins on the board. Connecting to it on reboot dumps out the bootloader messages, but goes quiet as soon as the kernel boots. Has anyone been able to get the kernel to output? I feel like I'm missing something simple.
It boots fine into the OS using stock CM12.1 nightlies, but my current modifications to the kernel is causing it to hang mid-boot without panic. Gettings the kernel to output to the UART console would be super helpful for debugging.

It's old though, did you manage to get kernel log on UART? This link says to get kernel messages on UART, kernel needs to be compiled with serial port driver enabled: CONFIG_SERIAL_MSM and CONFIG_SERIAL_MSM_CONSOLE.
Hello Android kernel hackers,
I am trying to port the current ASB-patched LOS12.1 (github "cm12-amami") to a Teclast 98 (M1E9) tablet for which kernel sources are missing. My build completes fine, however, I run into a boot loop due to kernel panic with an (at least for me) totally unhelpful stack trace:
During init.rc processing, the kernel panics on logd startup when logd tries to read from /proc/meminfo with the following stack trace:
Code:

Most interestingly, the exact same kernel blob can successfully boot stock Android 5.1 and successfully read from /proc/meminfo when booted from stock boot.img while it crashes with my LOS12.1 build boot.img.
bootimg.cfg (using abootimg) is identical in both cases (except the boot size):
Code:
bootsize = 0x780000
pagesize = 0x800
kerneladdr = 0x40080000
ramdiskaddr = 0x44000000
secondaddr = 0x40f00000
tagsaddr = 0x4e000000
name = 1513588375
cmdline = bootopt=64S3,32N2,64N2 androidboot.selinux=permissive
Thanks a million in advance for any ideas or pointers about what might be going wrong with this stock kernel blob and my LOS12.1 build with regards to meminfo_proc_show()! :highfive:
awl14
Issue resolved!
Finally resolved by making changes (a whole number of, so I haven't tracked it down to one particular change) to my CM12.1 build's system partition, making it resemble the stock image more closely.
I still don't have any clues why the kernel would crash on reading from /proc/meminfo due to "wrong"/buggy contents in the system partition (/system file system), but as the issue is resolved, this can be regarded as a proof that such content in system can indeed matter in a critical way for the behaviour of the kernel...
My custom ROM for Teclast 98 (M1E9) runs fine now, I will publish a download link soon on xda.
Panic caused by kernel reading file /system/bin/cpuinfo
I encountered the same issue and was able to find the root cause. The kernel I'm dealing with has been modified by Chinese crooks who fake the amount of memory in the device by intercepting meminfo_proc_show(). In this routine, they read the file /system/bin/cpuinfo, apparently extracting the value to be shown to the user as the memory size from that file. The code does not even test the return code from the file opening routine, and simply crashes the kernel if the file is not present.
