After a lot of frustration, I have finally got my HDMI to VGA adapter working. At first I got a very inexpensive adapter from Meritline. I could get the initial splash screen, but then nothing. Then I got a recommended adapter and cable that cost twice as much. I could get the initial screen for a few minutes, but then it disconnected.
Reading a post on Sparkfun, I realized that the adapter was pulling too much current through the Beaglebone. I touched the capactors next to the HDMI port, and they were very, very hot just before the VGA monitor lost connection. So I took the adapter apart to find where the 5 volt power was coming in. A little checking and I found which pin supplies the 5 VDC to the HDMI cable. I traced the pin out to the adapter circuit board. Then I cut that wire and soldered a wire onto it. I ran that wire to the Beaglebone circuit board where the barrel connector connects power in. I connected the wire up, powered up the board, then powered on the VGA monitor, and everything works like a charm now! The Beaglebone Black just can't supply enough 5 volt current to run the adapter, so it needs to be powered directly from the 5 vdc source. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
