Hello there, I have bought Wikipad WPT500 recetly, updated it and managed to set boot.img as insecure and root completely. Thing is, it's quite old already, so I would like to OC kernel a bit or at least install twrp. It has potential, that's for sure. Thing is, there's no source available. I;ve contacted dev team from them but no response.
Does anyone know the way to modify kernel (OC it, i know there's no way to add schedulers or governonrs without sources) or compile TWRP without sources, based on stock images ?

Having said that given you are a Senior member, you should be able to find out where such a question should be posed.
Thread Closed. Thank you.

Firstly, apologies but as a new member I cannot post to the developers area.
I want to know if anyone has put any effort into a port of android to satio? I believe the first part shouldn't be too challenging as Android has already been compiled to the OMAP3430 SoC. I am familiar with setting up an arm cross-compiling toolchain and have worked with the arm9260 chipset in this regard (including writing kernel drivers).
As I haven't developed for a phone before, I'm not sure how easy it is to access the bootloader and download a new kernel.
Beyond that I'm in new territory regards the neceeasry drivers and accessibility to the information to develop the kernel code required
I look forward to your comments.
Regards, Steve

Hi,
I'm following the Nexus S Android Development for 6 month now and Rom and Kernel flashing is a a real addiction for me (I flash everyday).
And, since the beginning i want to create my own Rom.
At first, I want to build one from another one (Cyanogen or another).
So, If someone can give me tutos, tools, tips and advices, I'll be very grateful.
Thanks to everybody, waiting for your help.

Hey you know i find myself sharing this exact interest as you. Let's collaborate and learn this Create A ROM Project
Notice to see the motivation to create a new ROM.
How good are your Linux skills? If you want to do it all properly I suggest you try and build your own AOSP ROM first (from the Adroid Open Source Project).
This is the place where Google publishes the Android source code files. Actually the site is fantatic and guides you through the entire process, but it does require you to understand the basics of the maketools in Linux.
Once you've been able to compile the source, you'll actually have a perfect stock ROM version of Android. Then, you can start doing advanced things to it. Add a different Kernel, add apps, install tweak scripts etc etc etc, the options are endless.

Good luck and have fun, because it is

Ok thanks!. i'm new on this forum and i did not now where post this!!!
Hi All,
I've been reading these forums for sometime now. Until now I've only been here as a user of roms not as a developer.
However, on my current project I had the requirement to get an android distribution running on a beaglebone black embedded board. As there are a lot of experienced rom developers here I would like to ask my question here.
Currently I'm successfully booting the kernel. It also seems to get to the actual homescreen. However, it seems that I'm currently in a bootloop a when I reach the homescreen. I get thrown back to the boot animation.
My guess is that there is some kind of memory issue here. More specifically the vmalloc part.
I get the following error in the dmesg when the homescreen crashes:
binder: 1804: binder_alloc_buf failed to map pages in userspace, no vma
Can anyone confirm that this is good explanation and tell me how I should adres this issue? Or maybe provide me with some other tips?
I tried to increase the vmalloc size but I'm not really able to do so. if I enter the vmalloc=512M command on the uboot it doesn't really change the size...
Thanks
Hi there,
You must read some guides and tutorials for that. Starting from:
1. This guide about how to port different ROMs to your device.
2. This guide about how to port AOSP ROMs to your device.
3. This guide about how to port a ROM to your device.
4. This guide about how to create a new ROM for your device.
5. This guide for ROM development beginners.
6. This guide in xda university for building your own android rom.
7. This guide in xda university for porting an aosp rom from source.
There are also instructions on the cyanogen mod wiki site about it.
A good place to ask if you have questions about it or need help, is Chef Central - Android. Many devs are watching this forum and can help quickly.
Good luck
Hi,
So I've been getting into android the past month and really started liking it. I have however some questions about how an android (or Linux) operating system works. I also have some questions about how the Kernel and the OS work together and what I need to know about it before I start learning more about and getting into developing.
1. Does the Kernel command the OS or the other way around?
2. Can I create a custom Kernel specifically for an OS?
3. How much experience do I need to create a custom Kernel and is it phone specific in the sense that if I make Kernel A for phone A will it be easier to create Kernel B for phone B?
I'm not native speaking, so please ignore any grammar issues.
I'd love to hear something from you all!
Kind regards,
Pinnekeshaar

Hello,
1) Yes
2) Yes
3) You really need to have an in depth knowledge of your device, linux kernel and you should know how to use git. Depending on how you want to get started, you can add more governors, hotplugs, upstream updates and more..
