Hi, I just did an update (apt update / apt upgrade / bootloader via armbian-config) while being on eMMC and it seems to boot back fine but the Ethernet link is down.
The board is usually used headless and when connected to an HDMI screen I can see the boot sequence up to the login prompt, the only things that do not show as "OK" are some network mounts (wired in fstab).
The board is not being given an IP by the router too.
Do you have anything in mind that I might try ?
Edit : I'm on Buster beta channel, the version installed (and working fine) was 5.8
