Hello, i'm new in the forum, but have been using the armbian images for a while now. My base image version is img-5.5.0-rc6-aml-s9xxx. I'm currently using the emmc of a Beelink Gt1(2GB RAM and 16GB) and when i try to use the apt update & apt upgrade normally i can't startup the box. Have to boot by sdcard, and copy the 5.5.0 files back to the boot partition of the emmc. My doubt is, when i run the apt update & apt upgrade does this mean that i've move forward in the image version? because the files in the boot don't change name, so i've no clue if i'm running the img-5.9.0-arm-64 or not. Other thing i've tried yesterday was to upgrade using the apt, and then place the img-5.9.0-arm-64 files in the boot replacing the 5.5.0 ones, but the box didn't boot. Any idea? Thanks for the great support and images @balbes150.
