Hello guys
Been using Armbian on my RockPi 4b as a media server for few months now and took every update up until the latest 25.5.0-trunk.185
Now this was made with apt upgrade command and after I reboot, system no longer boots at all, freezing on initial boot stage.
No HDMI sign at all also.
If I plug an old armbian that I have on sdcard, I see U-Boot screen for few seconds, then reboots (basically bootloop).
OS was installed to internal eMMC.
Downgraded back to Armbian_community_25.5.0-trunk.131_Rockpi-4b_bookworm_current_6.12.16_minimal from github and all is running fine, but again after upgrade command, same thing happens.
Not that skilled to debug this further.
What I remember is that I saw in the upgrade log that kernel was updated, so thinking it might be that.
