DM642- Video port, Dual port synched raw driver.

Started by a_ronningen October 3, 2005
Hi!

I'm writing a display driver on dm642. The format I want to transmit
is 4:2:2 (y/c), but because I need both mcbsp0 and mcbsp1, I cannot
run vp0 or vp1 in y/c mode (vp2 is taken for capture).

What I want to do is to sync vp1 to vp0, and emulate the y/c format.
vp0 could send luminance, and vp1 could send interleaved chrominance.
Then I would have to pick out hsync and vsync from one of the ports.

Does anyone see a problem with this approach, or should it work?

The mini-driver from TI does not support synchronization of video
ports. Has anybody here tried to add that functionality to the driver?
