Other Parts Discussed in Thread: TVP7002

dear all

I am working on a ti8148 project, i am a newer.I use EZSDK. I have a few questions.

the EVM have a TVP7002 decoder right? For some reason, I have to change it to ADV7403.?

When I add the ADV7403 driver(I use the V4l2 structure), how to debug it?

I have to "make linux" to rebuild the kernel right? anything else? how do I know whether my code is work ? what is the detail step?

whether the M3 firmware need to be reload?

can I use the OMX capture example to test my driver code?(I am not sure whether or not OMX project support the V4L2 sub-device)

Which EVM? There are a couple of different 'packages' I think which are targeted for different applications.

The base EVM Does not have a TVP7002 on it.

There is a daughter card which has HDMI and a TVP I believe though.

dear Margarita Gashova, thank you so much for your answer.

the question is: when I change my driver source code, should I load( or reload) the dm814x_hdvpss_v4l2.xem3 firmware?
