There are two ways to fix it: 1) dts|dtb , or script , to toggle the mux lines turning the regulators ON, or 2) mod the board so that the regulators are ON all the time !
The regulators are on the schematic on page 19; We'll do some testing and see if we can get a software fix; otherwise, we'll put up a board mod procedure.
HI
I am having problems with the USB 3.0 port and my external self-powered HD, wireless mouse and keyboard. Frequently, at boot, the Rock64 behaves like it forgets it has a mouse and/or hd. These devices work flawlessly with my PI III so I do not understand what's going on with my Rock64. Do you have any idea on how to fix this? I used the stock linux. Thx
