My HDMI and USB on BPI-M2 Berry do not work. They did work, but now do not. I have re-soldered the pin header, so am thinking I broken something, but I would like to work out what…
I have tried with Ubuntu Mate and Raspbian, both have the same issue. Currently I am working with Raspbian. I can SSH to it, and see the SATA port works, I have a hard drive attached to that.
If I run “tvservice -s”, I get: [E] Failed to initialize VCHI (ret=-1)
I have gone over the board checking closely for any shorts and cleaning up the flux off, but cannot see any issues.
