It looks like the relevant info to get going is here: https://mntre.com/reform2/handbook/advanced.html#system-boot There's a script to compile a custom u-boot: https://source.mnt.re/reform/reform-system-image/-/blob/main/reform2-imx8mq/mkuboot.sh #+BEGIN_SRC bash if [ ! -d u-boot ] then echo "Cloning U-Boot..." git clone --depth 1 https://source.mnt.re/reform/reform-boundary-uboot.git u-boot fi cd u-boot cp mntreform-config .config export CROSS_COMPILE=aarch64-linux-gnu- export ARCH=arm # build rescue u-boot first (loads kernel from eMMC) make -j$(nproc) flash.bin KCPPFLAGS='-DMNTREFORM_BOOT_EMMC' cp flash.bin flash-rescue.bin # build normal u-boot second (loads kernel from SD card) make -j$(nproc) flash.bin cd .. #+END_SRC So that doesn't look to complicated. Here's the custom u-boot: https://source.mnt.re/reform/reform-boundary-uboot It says: "Fork of the vendor (Boundary Devices) u-boot for Reform 2, with minor tweaks. The goal is to migrate to mainstream u-boot or barebox ASAP. The main impediment so far is the 4GB RAM config." So we probably want to make a u-boot-mnt-reform in gnu/packages/bootloaders.scm So we probably want to use "guix system image" and then add: gnu/system/images/mnt-reform.scm Ideally in the end we should be able to do: guix system image --image-type=mnt-reform my-os.scm So yeah, the rest of the pieces to figuring it out seem to be all here: https://mntre.com/reform2/handbook/advanced.html#system-boot It *seems* like this should all be possible... - Christine
