Building Kernel 3.x for NOOK Tablet (Regularly Updated)


Kuzma30 of XDA-Devs:

I've started porting 3.0.8 Android kernel to NookTablet. There are some results: it starts booting , have a look here: http://pastebin.com/0NEHVyLa
The repository is here: https://github.com/Kuzma30/kernel3NookTablet.Many features are disabled. I will enable them, one by one.Help is greatly appreciated!
EDIT. 02/06:
Will try initial booting a kernel of 3.2.2 branch. I use mainline kernel (from kernel.org). I created a new board file, based on 4430sdp, disable all i2c devices, display, add some early _print() messages. This is boot log:http://pastebin.com/z5fdyQQ3Now, there are less errors than in 3.0.8. And I think the 3.2.2 branch will take less patching.
I have decided to work on 3.2 branch from now on. The next steps are1. Enable our i2c devices.2. Enable backlight and display.3. ...


Некоторые дополнительные детали из переписки со мной:
По поводу текущего статуса и фотографий... Проблем еще много.
Вот текущий лог http://pastebin.com/kuuqiByZ. Включение tty2 вызывает краш ядра (надо разбиратся почему), поэтому пока он отключен. Инициализация дисплея тоже вызывает краш ядра. Проблема еще в том, что при крашах в консоли кроме сообщений early_print ничего не выводится, хотя оtладка включена(. Есть проблемы с emmc и mmc. Для первой неправильно читается таблица разделов, для второй - система ее просто не видит (ошибки инициализации).
Фотографий нет, так как пока на экран ничего не выводится).

hope the URL of last log will be corrected ASAP.
And it's corrected, and a *new* log below:

Problems start with power management: OMAPZOOM repositaries just don't have Power Management code mature enough to be grafted to 3.2.5 kernel branch. Then, there will be more similar obstacles from OMAP Android deficient code. I would think of thinking about building a webOS at this stage, but it's just me... fattire recommends to come back to Earth (i.e., Android). We'll see.

Иными словами, помощь нужна, товарищи кернел-билдеры и девелоперы! Пишите. Человек один уродуется, помочь некому. Олег Дрокин (verygreen) занялся было ядром 2.6.35.х для Нукколора, но отстал еще прошлым летом.
