For anyone who finds themselves unlucky enough to end up in the never ending boot cycle, but can access the bash terminal through the serial console, do the following:

  1. Mount the bootloader stuff:
    mount /dev/mmcblk0p1 /mnt
  2. Check that /mnt/boot/extlinux/extlinux.conf has this stuff:
    root=/dev/mmcblk0p1 rw rootwait rootfstype=ext4 console=ttyTCU0,115200n8 console=tty0 fbcon=map:0 net.ifnames=0 rootfstype=ext4
  3. If it does, I cant help you (if it doesnt exist, then create the file - lookup what it should look like). If it doesn’t you’ll need to sed it in. For Xavier, you can do the following:
    sed -i "s|^\([ \t]*APPEND \${cbootargs}\) .*|\1 root=/dev/mmcblk0p1 rw rootwait rootfstype=ext4 console=ttyTCU0,115200n8 console=tty0 fbcon=map:0 net.ifnames=0|" /mnt/boot/extlinux/extlinux.conf
    for others, refer to here
  4. You should now be able to boot into recovery mode and re-flash.
