Hey! @sicxnull I flashed your image on an SD card using balenaEtcher and I'm trying to boot it from a similar board as our friend here. Allwinner H3.
Problem is that it doesn't boot from the SD card, it keeps booting from the current image. I have tried some images of LibreElec (https://libreelec.tv/downloads/allwinner/) and the board actually tries to boot from the SD (though it gets stuck into "Loading Kernel...").
Am I missing something with your image booting process? Thanks!
