Hi all, it is a pity to forget this topic forever. As a newbie who own AM40 board, I still want to run armbian on it..
I accoccasionally got an this board, it is quite able to serve as an android tvbox board, but can't do more due to the stock rom.
I find maskrom pin on the back of the board. I think it is possible to run Armbian on it.
Here are some of my research result:
if on stock android rom. connect the board's upper usb port to computer with male to male usb cable, flip the adb/nomal switch to adb mode, press the white switch and power on the board, the board can enter loader mode. then I can use rkdevtools to switch the board to maskrom mode.
if on other boot loader, can shot maskrom tp for about 20 seconds and enter maskrom mode.
