I’m trying to setup a new Asus tinker board with hass.io.
The board model i’m using is the regular (not S - RK3288).
After flashing my sd card with Etcher, i plug it into the board and it start and lot of lines running on the screen. after about a minute it turn off and there it ends.
I had the same issue, it was the power supply not powerful enough. Turned out with a more powerful one connected direclty to the +3.3 and Gnd Gpio pins instead of using the USB C connector
