Has there been any updates on this topic? I am running into the same problem. (Tinkerboard 2)
@tooz it is impossible to get any information out of the Tinkerboard, it completely stops working and needs a power cycle before it can operate again.
I am using a 7" Hicenda HF7SMP-7CTP TFT diaplay with touch, attached is the HDMI driver board that has a Micro USB 5V and a Micro USB 5V + Touch.
When i connect it to the one with touch is when all the problems start happening.
Thanks!
