How to install Trisquel 10 (etiona) on 32bit ARM SBCs
If you're doing that on Parabola, you need to enable etiona support:
# cd /usr/share/debootstrap/scripts/ # ln -s trisquel etiona
Then you can install Trisquel as usual:
# qemu-img create -f raw storage.img 2G # fdisk storage.img # create 1 partition # udisksctl loop-setup -f storage.img # mkdir rootfs # mkfs.ext4 -O ^metadata_csum -O ^64bit /dev/loop0p1 # mount /dev/loop0p1 rootfs # mkdir -p rootfs/usr/bin # debootstrap --foreign --arch armhf etiona rootfs # cp /usr/bin/qemu-arm-static rootfs/usr/bin # LANG=C.UTF-8 chroot rootfs qemu-arm-static /bin/bash # export TERM=xterm-color # /debootstrap/debootstrap --second-stage
You then need to create the extlinux.conf file in /boot/extlinux/extlinux.conf with the following content:
menu title Welcome to U-Boot with Extlinux support!
timeout 10
label Trisquel GNU/Linux-libre, linux-libre kernel
kernel /boot/vmlinuz
append loglevel=8 root=/dev/mmcblk0p1 rw
fdtdir /boot/dtb/
initrd /boot/initrd.img
Then you need to install a kernel:
# LANG=C.UTF-8 chroot rootfs qemu-arm-static /bin/bash # source /etc/environment # apt remove flash-kernel # apt install linux-image-generic
You then need to write a script in /etc/kernel/postinst.d/zz-generate-dtb-link to generate a symlink from /lib/firmware/<<your-kernel-version>>/device-tree/ to /boot/dtb, so for instance from /lib/firmware/5.4.0-96-generic/device-tree/ to /boot/dtb. I've an incomplete script here:
#!/bin/sh
set -e
version="$1"
ln -sf /lib/firmware/${version}/device-tree/ /boot/dtb
The caveat of this script is that it has not been tested with multiple kernel versions installed, so during apt upgrade, it may or may not make the /boot/dtb link point to the wrong kernel. So that needs to be tested.
With only one kernel installed it should not be a problem.
In addition to that you will also need to make the symlink yourself the first time, before booting the image, like that:
# LANG=C.UTF-8 chroot rootfs qemu-arm-static /bin/bash # source /etc/environment # ln -sf /lib/firmware/<your-kernel-version>/device-tree/ /boot/dtb
You will need to replace the <your-kenrel-version> with your kenrel version, for instance:
# LANG=C.UTF-8 chroot rootfs qemu-arm-static /bin/bash # source /etc/environment # ln -sf /lib/firmware/5.4.0-96-generic/device-tree/ /boot/dtb
You will then need to install a bootloader, here's an example for the beagleboard:
# LANG=C.UTF-8 chroot rootfs qemu-arm-static /bin/bash # source /etc/environment # apt update # apt install u-boot-omap # cat /usr/share/doc/u-boot-omap/README.Debian # dd conv=fsync,notrunc seek=256 if=/usr/lib/u-boot/omap3_beagle/MLO of=/dev/loop0 # dd conv=fsync,notrunc seek=768 if=/usr/lib/u-boot/omap3_beagle/u-boot.img of=/dev/loop0
