Recently with help of other I have managed to design and build a HDMI circuit that is connected to the LCD pins of BeagleBone Black available on the side header. The video circuit itself is placed on a shield connected to the BeagleBone Black. The design is based on the BeagleBone Mx video circuit with only one difference- its 16 bit like in BeagleBone Black.
I have attached the schematic showing the connections.
For many days now I was trying to get the video signal be succesfully sent to the monitor connected to my circuit with no luck... I have disabled the default HDMI tree overlay and replaced it with the one that doesnt have audio and edited it a bit, to match my design (changed the I2C0 bus to I2c2 and changed the driver to TFP410 from TDA chip).
This is my overlay file: http://pastie.org/private/j91tplpqnhymvvig1pc0rw
When I boot the board, in the serial debug output I see some errors that I cannot resolve:
[ 6.507830] tilcdc 4830e000.fb: no encoders/connectors found
[ 6.513806] tilcdc 4830e000.fb: failed to initialize mode setting
I would really be gratefull for someone to help me with this problem, that I cannot solve for many days. There is still no video showing on the connected monitor, even though I see the monitor on the I2C2 bus.
