Hello,
gpio seems messed up on my rb912 board with 4.9 (latest trunk build)
With 4.4 stable build you can switch between mPCIe and USB by changing 52 pin: 1 = usb, 0 = mPCIe, but with 4.9 nothing really changing, usb works with both 0 and 1, and so mpice doesn't.
Well,this commit may have caused it:
https://github.com/lede-project/source/commit/65da6f9ca164cc321a84f28c81785a21af6af6fd
You can try reverting it and building image to test
Did anyone have any luck getting this to work? I can't get the GPIO working to turn on the internal USB on the MPCIE connector as well.
Kernel 4.9 here as well
I fixed this some time ago:
