Archlinux has dropped 32 bit software builds and thus most of the software builts will need to compile manually. This guide is only here as reference and it is not recommended to continue run this hardware.

Based on https://kiljan.org/2021/04/22/installing-arch-linux-arm-on-an-iomega-ix2-200/

This guide uses a usb device as system disk.

You may get all tools by enter nix-shell if you have nix installed.

mkdir linux
cd linux
wget https://mirror.archlinuxarm.org/arm/core/linux-kirkwood-dt-5.15.6-1-arm.pkg.tar.xz

mkimage -A arm -O linux -T kernel -C none -a 0x02000000 -e 0x02000000 -n "Arch Linux ARM kernel" -d boot/zImage-dtb boot/uImage

The final image will be in ./linux/boot/uImage

Use fdisk to partition the disk:

fdisk -l # If you don't know your drive
fdisk /dev/sd{some letter here}

Use o to create a clean DOS partition table.
Use n to create a new partition, type: primary, number: 1, first sector: default, last sector: +256M.
Use n to create a new partition, type: primary, number: 2, first sector: default, last sector: +8G (or the rest of the remaining free disk space if smaller).
Use p to see the new partition table.
If ID and Type are not ‘83 Linux’ for both partitions: Use t to change a partition’s type. Type must be 83.
Use w to write the changes to disk.

Replace {} with correct letter

mkfs.ext2 /dev/sd{}1
mkfs.ext4 /dev/sd{}2

e2label /dev/sd{}2 ROOT

mount /dev/sd{}2 /mnt

cd /mnt

Also, you will need to copy the file from ./linux/usr/lib/modules to the /mnt/usr/lib/modules. Remove the previous one.

rm -r /mnt/usr/lib/modules
cp -r ./linux/usr/lib/modules /mnt/usr/lib

For automatic update, copy the zImage and dtb to boot as well.

cp ./kirkwood-lenovo-ix2-dl-full.dtb /mnt/boot/
cp ./linux/boot/zImage /mnt/boot

Choose either way to do this:

First, enable ssh: visit https://{IP}/manage/diagnostics.html

• User: root
• Password: soho{password you set}

fw_printenv > /tmp/env

backup and set up the following so that your device will boot from usb first

fw_setenv mainlineLinux 'yes'
fw_setenv arcNumber '1682'

fw_setenv bootargs_console 'console=ttyS0,115200'
fw_setenv bootargs_mtdparts 'mtdparts=orion_nand:640k(u-boot)ro,16k(u-boot-env),-(iomega-firmware)ro'
fw_setenv bootargs_root 'root=LABEL=ROOT rw'

fw_setenv memoffset_kernel '0x01000000'
fw_setenv memoffset_initrd '0x08004000'

fw_setenv bootargs_combine 'setenv bootargs ${bootargs_console} ${bootargs_mtdparts} ${bootargs_root}'
fw_setenv bootlinux 'bootm ${memoffset_kernel} ${memoffset_initrd}'

fw_setenv usb_load_firstdevice 'ext2load usb 0:1 ${memoffset_kernel} /uImage; ext2load usb 0:1 ${memoffset_initrd} /uInitrd'
fw_setenv usb_load 'run bootargs_combine; usb reset; run usb_load_firstdevice; run bootlinux'

fw_setenv sata_load_disk1 'ext2load ide 0:1 ${memoffset_kernel} /uImage; ext2load ide 0:1 ${memoffset_initrd} /uInitrd'
fw_setenv sata_load_disk2 'ext2load ide 1:1 ${memoffset_kernel} /uImage; ext2load ide 1:1 ${memoffset_initrd} /uInitrd'
fw_setenv sata_load 'run bootargs_combine; ide reset; run sata_load_disk1; run sata_load_disk2; run bootlinux'

fw_setenv bootcmd 'run usb_load; run sata_load'

Tips: To access UART, removing the front panel (5 screws) is easier than back (need to remove cables)

• The top three pin (JP1) with jump is for 3.3v/5v mode, by default is 3.3v.
• Skip the first Pin (Which is the one from the right when you pointing the pin toward yourself, board facing up) and connect as following:

Pin 1: Do NOT connect. This pin provides +3.3V and is not required for USB UART serial adapters.
Pin 2: TxD. Connect to RxD of the serial adapter.
Pin 3: GND. Connect to GND of the serial adapter.
Pin 4: RxD. Connect to TxD of the serial adapter.

Connect console:

screen /dev/ttyUSB{varies} 115200

The following will show up:

        |  \/  | __ _ _ ____   _____| | |

Tips:

• In screen, you could use ctrl+a, then esc so you can scroll.
• How to check which dev is the usb? check dmesg. https://superuser.com/questions/361885/how-do-i-figure-out-which-dev-is-a-usb-flash-drive

printenv

backup then set vars, Do NOT copy/paste all commands since this will result in incomplete executed commands due to the lack of flow control on the serial interface in U-Boot. A copy/paste of each line separately should be OK.

By default, the device will not mount boot partition, and your hard drive. Example /etc/fstab:

# Static information about the filesystems.
# See fstab(5) for details.

# <file system> <dir> <type> <options> <dump> <pass>
/dev/disk/by-id/xxxxx-part1 /boot ext2 defaults,noatime 0 0
/dev/disk/by-id/xxxx-part1 /data ext4 defaults,noatime,barrier=1 0 0

Set all DHCP

sed 's/eth0/e*/g' /mnt/etc/systemd/network/eth0.network > /mnt/etc/systemd/network/eth.network
rm /mnt/etc/systemd/network/eth0.network

With your drive mounted:

mkdir /mnt/etc/pacman.d/hooks
cp generate-ubootfiles.hook /mnt/etc/pacman.d/hooks
cp generate-ubootfiles /mnt/usr/local/sbin/
chmod +x /mnt/usr/local/sbin/generate-ubootfiles

Test the script by running on the machine

https://archlinuxarm.org/platforms/armv8/broadcom/raspberry-pi-3

pacman-key --init
pacman-key --populate archlinuxarm

# Needed for uboot generation
# Update required for system to run
pacman-key --init && pacman-key --populate archlinuxarm
pacman -Syu --noconfirm uboot-tools mdadm gptfdisk parted rsync arch-install-scripts

Also, add IgnorePkg =a linux in /etc/pacman.conf, so it won't touch our linux module.
