@Nick A TY very much for your reply, I've managed to create my first build but I am a bit confused because it made an IMG with a FAT32 boot partition, is it right or did I miss something?
@Nick A Is it possible that you can make a secure boot version of the X96Q V1.3 debian minimal or tell me, how I can build it myself on MX Linux (Debian based)?
Never done this before yet and sadly, my X96Q (plus) is based on Allwinner H616 with a single MMC (1.5GB DDR3 RAM and 8GB ROM)
