Hello Robert,
Thank you for your reply. I do have AN-1337 thank you
I think we are reasonably happy that the interface with the i.MX6Q MIPI CSI-2 receiver is configured correctly because we have no issues capturing video when the ADV7280-M a) is in forced free run mode or b) has the input standard forced to PAL or NTSC (with reg[0x2]). Is that a fair assumption to make?
I can answer some of your questions right now:
1) We only have one part
2) We are using an ADV7280-M EVM connected to a Variscite VAR-SOM-MX6 board.
Connections are with 50 Ohm coaxial cables (cable length has been kept to a minimum)
3) and 4) We have tried two different CVBS sources. A PAL camera and analog video
output from a Raspberry PI. In both cases we saw the same behaviour, as described in
my original posting.
5) We will try to get an oscilloscope plot as requested
Best regards,
Stahis
