Now I am trying to use with a BBB, from Adafruit and it does not work with either monitor. One is a 20" 2000x1090 widescreen monitor that works well at widescreen resolution. Is there some secret to get this to work with the BBB? It originally comes up with the BBB logo at the top left, then goes black. Would a later Angstrom version fix this?
Jim Sometimes the HDMI/VGA adapter requires power from the board HDMI connector is attached to. If the BBB is unable to supply the correct power or sufficient power, the adapter will not work. Some HDMI/VGA adapters use an external power source. An external power source solves some problems. The HDMI circuitry expects 5V at pin 18. I have looked at the BBB schematics and pin 18 , P6 is shown as HDMI-SDA. This seems wrong. I will pursue this further. http://elinux.org/Beagleboard:BeagleBoneBlack_HDMI 99guspuppet -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
