I have an Armbian installation on the NVMe drive and I'm trying to switch back to boot from SD card. In `armbian-config` I messed up the boot settings by leaving the root fs type unchanged, (SD card is in fat32 but NVMe partition is ext4). Now the board boots into initramfs prompt.
Here's what I've already tried based on search and ChatGPT:
Mount the NVMe partition to `/mnt` then chroot to it, this did work but the `/boot` partition was not mounted inside of the chroot so I can't fix boot env.
I also tried `switch_root` but it's not available in the initramfs prompt.
Update `/proc/cmdline` to change the root fs back to the Armbian partition, but `echo ... > /proc/cmdline` doesn't really do anything.
Any ideas?
