That’s fascinating. I guess it’s worth sticking to the non eMMC version if you’re starting, but if you really want to “hack” and get the most of the uConsole then get an eMMC version to lpay around and make it work… or if you have enough experience to make it work. (I know I still have a long road beforme me, so I will pass… for now.)
Also, I had missed this thread which seems very interesting and helpfull
