Rockpi 4A doesn't boot after package update to 25.8.1

[toine512]

Hello,

 

I just apt upgrade-ed my Armbian 25.5 from mid-August to 25.8.1 and it doesn't start after software reboot. It is usually headless, I plugged it into a monitor and all I get is a uboot logo in the top left corner. No message, nothing.

The board is the Rockpi 4A. The system is on eMMC 😩

 

What do I do now to at least roll back ? At worst make a browsable copy of the eMMC ?

 

Thanks!

Antoine
