Hello, today I started using my A64. I downloaded this image -> https://images.olimex.com/release/a64/A64-OLinuXino-bullseye-base-20231106-081613.img.7z
flashed an sd card (bought via olimex) with balena-etcher, put the card in the A64 and connected an hdmi cable. I waited for ~ 1min and then I was presented with a debian screen. I ran "shutdown -h now" and pulled the power plug, a few minutes later I plugged the power back in and nothing happened.
I then flashed the card again and after reinserting it into the A64 debian booted again normally. Then another reboot, and again nothing happened.
Next (after reflashing) I tried connecting the a64 directly to my router. after the first boot I ran "sudo apt update && sudo apt upgrade" via ssh and finally "sudo reboot". And again, now nothing happens.
how could I fix this behaviour?
After the reboot some improper config gets loaded and it disables either the whole video output or the HDMI. My advice is to open the terminal and try different options with command "olinuxino-display". Firs try the last option "DISABLE":
DISABLE Disable configured panel
Save and reboot and see if HDMI comes online.
