Hello. I saw all topics about armbian on Q8, Q88 tablets, but some of them are dead with no success, some say, that it is working somehow for someone. I understand, that armbian more tended to be for boards, but come on! There is a huge pile of tablets, that uses same processors, memory, wifi and other chips, and there is a sun5i-a13-q8-tablet.dtb in /boot/dtb of an image of armbian.
So, I compiled custom Armbian image using olinuxinoA13 configuration as there wasn't any for q8-tablet. Wrote or burned it with USB Image Writer (I'm on Linux Mint 19 Cinamon) on SD card, mounted it, edited ArmbianEnv.txt line disp_mode=800x480p60. Put SD in tablet, pushed on button... seems that nothing is going on. I even edited boot.cmd at line setenv disp_mode "800x480p60". No luck.
As I understand, script.bin is no more used here for booting. So, I'm stuck.
