Hello. I made a clone of my Wandboard's system card (using dd) and when I insert it and reboot the Wandboard starts to boot from it, but then throws me into Emergency mode with the message "Can't find PartUUID xxxxxxxx" Looking at the cloned card with blkid it looks identical, except that the cloned card has no PartUUID whereas the original card does. They both have the same UUID.
My question is, if I edit /boot/boot.txt to read
$this->bbcode_second_pass_code('', 'setenv bootargs console=${console} root=UUID=${uuid} rw rootwait')
instead of
$this->bbcode_second_pass_code('', 'setenv bootargs console=${console} root=PARTUUID=${uuid} rw rootwait')
as it now reads, and then run mkscr to make a new boot.scr, will the new card then boot?
I'm afraid to try it because (full disclosure) I don't know how to get in and change it back if I end up in emergency mode.
Hoping for help, cheers to all
Les
