i am trying to capture data from linux 3.10.17 and imx6. I can't capture, there is no BT656 data on the 16bit bus, and linux driver times out since no EOF (end-of-frame) is detected
I think there could be some hw issue in the board.
What i tested is:
analog video signal, seems good.
on capture commands (i2c) is see this signals generated:
XTAL 28652 Mhz
Pixclock (LLC) 27Mhz.
HS is in synch with analog input Composite signal.
No data at all is visible on D0-D15 lines. And this match with Linux times out.
As a test, i disconnected D4 line, and seen no data at all is generated at the same.
I see possible issues on the analog input signal. In which cases the converter gives out no data ? My board has an SVideo connector, so i have to convert Composite to SVideo with a converter.
Every help is appreciated.
