[C2] kernel 6.12.x broken

[teknoid]

my C2 did not boot after upgrading from 6.6.63-current-meson64 to 6.12.17.

I also tested kernel 6.12.13 from debian minimal image, same problem:

I have no idea. Can someone verify?

So for the moment I do not recommend updating to latest 6.12 kernel on Odroid C2.

C2 was tested booting from a fresh image. Probably u-boot updating is mandatory prior to upgrade.

I upgraded all in one step, uboot, dtb, ... Then switched back the kernel to 24.11.1 and it was working again

I'll do further investigations...

hmm, strange. After manually recreating the boot script it worked:

mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr

I did not take care of the output during upgrade, probably I missed a "No space left on device" or similar...

Anayway, solved...

[teknoid]

Now I've got it: It does not boot from emmc module if a sdcard is present!
