BeagleBone Black - No HDMI Output

Initially had the same problem.

Connected old screen via a micro-HDMI to VGA adapter. Screen was flickering with the factory image on the BBB.

Created a microSSD image to version 6-6-2013

For a brief moment (a few seconds) I could see the UI on the screen.

After the timeout event, the turn on the monitor turned black.

Hope somebody got a step futher.


I connected it to an old TV and it flickers (mostly black) with the post April builds. The last build I tried in 6/6 and it flickers in the same way.
I swapped out the micro hdmi to hdmi cable as well, still flickers. I tried a different tv and it kind of improved. There is a jitter every second or so and the contents are off the screen but at least I can see the screen (annoying as though).

So, I know it is able to work on my older screen since it worked with the original image that came with the board (minus the audio).
