Hello,
We designed a custom board using DM8168,
and we connected the DM8168 with FPGA which can provide video source to ARM through VPSS.
And we are using EZSDK 5.02.02.60, omx 05_02_00_15.
The capture demo already worked using our FPGA,
but when I change some logic in FPGA, capture can not capture any thing from FPGA.
I can get the FillBufferDone signal, but the received data size is not right and it is changing all the time.
Also the data is wrong.
I have compared the signal from FPGA and I can't find what's the different between previous.
I want to know how does the HDVPSS detect the active pixels ,active lines, frames ,blanks using SAV/EAV.
So if I can get the log from VPSS I think I can get more message about this problem.
But I don't know how to start, Is there any method to debug the VPSS of DM8168
Thanks very much.
Regards,
Lei
