So i got a ZERO and a ROCK 3E with the Intention to flash Android onto. Plan was using them for round 4"&5" displays as car gauges.
SADLY it seems not possible to flash Android 9 or another Android to eMMC 🤷🏻
Tried a Ubuntu on SD and it works.
Guess there’s not solution yet?
Ok, i am a noob on that things but can follow instructions 
…sure i have old Samsung s8 board laying around to use as a backup…will see if i can drive the displays with.
But form factor of ZERO would be nicer
you have Radxa Zero, right?
You can install SlimBoxTV Android right now.
you can also install LineAge Android 14.
Oha, i will try that. Via SD or emmc? I have eMMC and will use that. Seems difficult to flash to emmc.
Thanks
