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 using parted, fdisk, cfdisk or something else:
Device Boot Start End Blocks Id System
/dev/sdd1 2048 6143 2048 53 OnTrack DM6 Aux3
/dev/sdd2 6144 3842047 1917952 83 Linux
There are step by step instructions here. The first partition is of the special 0x53 type, 2 MiB are enough. It will contain the bootloader and its environment.
The second is your rootfs partition. You may create additional ones if you like and edit /etc/fstab to your liking.
Install the bootloader
Download a prebuilt u-boot.sb file or follow the instructions here to build one.
Write it to the first partition at 2 kiB offset:
dd if=u-boot.sb of=/dev/sdcardpartition_1 bs=512 seek=4
TODO: Configuration of U-Boot, links to docs, uEnv.txt.
Install the root filesystem
Download the rootfs tarball from this listing on archlinuxarm.org and extract it on the mounted rootfs partition. It is important to do the extraction root, not with sudo.
sudo mount /dev/sdcardpartition_2 /mnt/rootfs
tar -xzvpf ArchLinuxARM-olinuxino-latest.img.gz -C /mnt/rootfs
Generate a custom filesystem
You can generate your own alarm root filesystem with the pacstrap tool. This can be done from within a running alarm installation, on an imx233-olinuxino, another more powerful board, or even from within qemu running alarm:
# as root
pacman -S arch-install-scripts
# this creates the rootfs on a local disk, but the steps
# can be executed directly on a mounted sdcard partition
# this will setup a new alarm root filesystem in ./rootfs and install the listed packages
# this is possibly the absolute minimum for a working system with network
pacstrap -cdGiM ./rootfs filesystem linux-olinuxino inetutils iputils nano vi netctl dialog openssh pacman ppp systemd-sysvcompat usbutils wireless_tools wpa_supplicant
# install a custom kernel
Beyond the bare minimum, you can install more packages to the newly created rootfs:
pacman -r ./rootfs -S bash-completion vim samba lighttpd git ...
