ArchLinuxARM on iMX233-OLinuXino
This page explains the ways to install ArchLinuxARM (alarm for short) on iMX233-OLinuXino boards. Instructions should work on all 3 variants: maxi, mini and micro.
The official image
The easiest way to install alarm: just follow the official instructions. The image is pre-partitioned and has everything in place. It uses bootlets, so any time the kernel cmdline or DT binary need to be changed the bootstream needs to be rebuilt and reflashed.
When upgrading the kernel or installing a custom kernel package it is essential that you hit "y" when asked "Do you want the new kernel flashed onto mmcblk0p1? [y|N]". If not, the bootstream containing the new kernel will not be used after a reboot, with its modules already uninstalled.
U-Boot makes the board much more hacker-friendly.
This will hopefully soon become the official installation method, but it requires a few advanced steps at this point.
Partition the SD card
Achieve the following partition layout:
Device Boot Start End Blocks Id System
/dev/sdd1 2048 6143 2048 53 OnTrack DM6 Aux3
/dev/sdd2 6144 3842047 1917952 83 Linux
The first partition is of the special 0x53 type, used by the processor to boot. It will contain the bootloader and its environment.
The second is your root partition. You may create additional ones if you like.
Install the bootloader
Either find a prebuilt u-boot.sb file to flash, or follow the instructions here to build one.
Write it to the first partition at 2 kb offset:
dd if=u-boot.sb of=/dev/yourfirstpartition bs=512 seek=4
Install the root filesystem
Generate a custom filesystem
