After upgrading to latest Syncloud (Ubuntu 24...) my Odroid HC4 is stuck on Petitboot

Hi Boris,
after upgrading my Odroid HC4 to the latest Syncloud distribution (Ubuntu 24… vs the previous Debian 10 buster) I got stuck on Petitboot. I can only press the physical button on the device to skip Petitboot to make it run successfully. This prevent me to make a restart remotely or to be sure that, in case of a temporary electric failure, the system reboot successfully.
I have forced Petitboot to boot the right partition (instructions here ) but nothing changes.
To verify that nothing is wrong with Petitboot itself, I have tried the old SD card with Debian 10 and it works fine. I have found several workarounds (example: fw_setenv skip_spiboot true within Petitboot prompt), I have also tried to totally remove Petitboot without success because the shell tha is offered does not contain the required commands (erase_flash, if I well remember).
Any suggestion? Thanks a lot.

Simone

Sorry did the upgrade without proper testing on my device, let me check if I can fix the image
