Kernel git repository for N900
There is git repository for upstream linux kernel with all N900 patches.
https://gitorious.org/linux-n900/linux-n900
This git repository is used for development. All other git repositories on internet are older and does not contains all patches.
U-Boot
Instead of booting the kernel directly from NOLO (which restricts you to using exactly one kernel), U-Boot can be used as second bootloader. The Maemo kernel can be appended to U-Boot to keep the existing Maemo installation working (U-Boot must be located at the location of the Maemo kernel). The resulting boot process will end up like this: NOLO -> U-Boot -> Kernel.
Pali Rohár has been working on getting the N900 support into the mainline U-Boot:
description | date | status |
---|---|---|
Board Support | 2012-10-29 | mainline |
Bootmenu Support | 2013-03-07 | mainline |
Currently all U-Boot development for the Nokia N900 is done in this git repository: https://gitorious.org/u-boot-shr/u-boot (branch pali).
There's also a thread on talk.maemo.org, where the latest released & tested version can be found: http://talk.maemo.org/showthread.php?t=81613
Flashing
There is open source flasher application 0xFFFF which working with Nokia N900. Git repository is on: https://gitorious.org/0xffff/0xffff
