[Armbian for Amlogic S805 and S802/S812]

Anyone got Armbian working on M8 clone? (M8&M9_V02)

[Armbian for Amlogic S805 and S802/S812]

How do you even edit the uEnv.ini
When I flashed the (latest) Armbian_5.78_Aml-s812_Debian_stretch_next_5.1.0-rc5-next-20190418-g3f018f4a0-dirty.img with rufus, I cant even access my sd card (says i need to format)  I downloaded previous versions and 5.73 lets me see the uEnv.ini file

How do I get logs?
Right now it goes multicoloured pixels then black screen then remains at no signal.
I can see the ip address of it in my router admin page.
 

S802 btw (chinese clone tv box)
