I've successfully booted Armbian from USB following the tutorial above, and I've managed to write Armbian from the USB drive to the eMMC. Now I want to create an Armbian firmware that can be directly flashed to the H96 M9/S eMMC using RKDevTool.exe, but I'm not very smart - even simple things take me a very long time to figure out. If any of you have this, please share it. If I manage to figure it out, I'll also share my findings.
