From what I've seen, that particular tool is not as well maintained as some others. If it's a major uboot failure, it won't boot. If it's working, I think that's your answer.

It may be possible. But due to limited resources, forum support is limited to using Armbian as-is. Everything else goes in Off Topic. If you're truly interested, you could attempt to take the Armbian bootloader, kernel, and device tree, and drop that into a Guix install. But at that point, you are very much on your own.

@FrancasioHi, could you direct me to the link for that image? Thanks.

Guation. Would you be willing to share the patches (or Git commits) used to build the 1 GB Cubie A5E images? I'd like to incorporate them into the current Armbian build framework instead of using a prebuilt image.

i used nand-sata-install to move root from sd to ssd. at the end just after "Finalizing file sync ... Please wait" i got "Error while creating U-Boot loader image with mkimage" at the bottom of the screen. i rebooted and all seems to be working as planned. is this error anything to worry about?
