I originally used "guix system init" to install mine from the booted Debian system. "guix system image" at least used to assume cross-compilation, so I have not tried it, but maybe that would work to cross-build an image from an x86_64 system that you could then DD to the SD card. You could adapt: https://codeberg.org/vagrantc/mnt-reform-guix-config/src/branch/main/config-mnt-reform.scm First I would boot your MNT Reform with whatever OS you have now. You will need to make some changes to kernel-arguments (check the contents of /proc/cmdline) and initrd-modules (check lsmod output). My guess for kernel-arguments: (kernel-arguments '("no_console_suspend" "cryptomgr.notests" "loglevel=3" "console=ttymxc0,115200" "cma=512M" "pci=nomsi")) For the initrd-modules, you should be able to just add all the modules you get from lsmod. Probably overkill, but hopefully will work! :) You should also probably adjust the hostname, username, and probably remove the file-system entry for /tmp, and definitely the file-system entry for / rootfs. This is all standard guix system stuff so I am not going to get into specifics. :) Remove the u-boot-mnt-reform-rk3588 to save yourself some useless build time, since that is for a different platform anyways! > Hm, but where would the uboot come from then? You might need to manually install u-boot on the SD card, unless you are lucky and it is installed on the eMMC built into the imx8mq module: https://source.mnt.re/reform/reform-handbook/-/issues/2 Let us hope you are lucky. :) Otherwise, you will need to download or build an appropriate u-boot image and then manually dd to the SD card at a specific offset I do not recall off the top of my head, but luckily it is documented: https://source.mnt.re/reform/reform-boundary-uboot/-/blob/master/flash.sh If there is a flash.bin in your current /boot, you might be able to use that, either installing it to eMMC or installing it to the new SD card. When you try to boot it, you will probably want to connect to the serial console, unless you are even luckier and need to do no further debugging! Hopefully that is enough to get started. :) live well, vagrant
