I'm having some problems with a system on which i have two copies of the os installed on a cm4 where i can't get the second one to boot.
This is the layout of the disk, i mounted the second root and boot partition to check if i can access them and they show up readable ad i can read/write on them.
The first partition is a small fat32 just for the autoboot file, the fourth partition is the extended partition that contains the other logical disks.
I cloned mmcblk0p2/3 withand i have changed cmdline on the second root partition to
console=serial0,115200 console=tty1 root=PARTUUID=cec498e0-06 rootfstype=ext4 fsck.repair=yes rootwait
so that it points to the correct root partition.
fstab on the second root has also been changed to point to the correct ones:But when i try to reboot to the second OS, either by changing it in the autoboot.txt or with tryboot i get an error in the boot screen:
Trying partition 5
Failed to open partition 5
blkid shows me the following:Does anyone see anything i might be doing wrong here??
