Thoughts?, suggestion?

Joulinar · 29 September 2025 07:47

maybe @MichaIng has an idea

Melomane · 29 September 2025 13:28

What about this line?

There are some problems:

Yea, this should be root=PARTUUID=…?
So a “hard” boot is working, but not when you just reboot the system?

@russ-go can you show the output of these commands:

printenv
cat /boot/armbianEnv.txt

And what would be also intersting:
Make a normal reboot and a hard reboot, in both cases you cancel and go into the uboot prompt.
Do printenv | grep root

You can also try to boot only with eMMC OR SD connected, not with both at the same time.

Yes. Booting from a powercycling boots fine. Does not recover from a reboot or shutdown -r now

You can also try to boot only with eMMC OR SD connected, not with both at the same time.

To clarify, I’ve installed the bookworm and trixie images from SD and from EMMC, but never both at the same time.

printenv output:

Note - For the life of me, I CANNOT get the board to boot into the uboot shell. Tested my FTDI and it’s transmitting just fine but the serial console doesn’t recognize my input.

Will try again tomorrow.

Note 2 - Powercycling does not reliably boot device to login
