Hey Sarathkumar,
i´m not sure, but i think the PVP won´t work, if you run it without any Blocks.
Try to run it with a CNV with a 1 in the middle.
Another thing i had problems with, is the interrupt generation.
Do you get an interrupt when PVP is finished?
If not, try to pause your program in a moment, you are sure your cam had transmit the hole frame and check the Register DMA46_ADDR_CUR, DMA46_XCNT_CUR and DMA46_YCNT_CUR.
ADDR_cur you can calculate. The others should be zero.
And check DMA46_STAT.RUN, if it is 1, then your PVP isn´t finished yet.
Your DRAIN bit is on in PIPECTL. I tried this to, without success.
Try to set the stop mode for DMA46 and then let the PIPECTL.DRAIN=1 and set IPF0_FCNT=1.
Good luck
Tim
