DM368 old frame repeat Issue ?

Hi

On my DM368 Platform, i find that old frame will repeat again, or new frame has old frame data.

My buffer number = 4, and if frame order is 0, 1, 2, 3, 4, 5, 6..... 

and sometimes capture thread will get error frame order like 0, 1, 2, 3, 4, 1, 6, or some frame has old frame data.

I find that this maybe is related with rsz's dmainterval.  Is it right ?

 

EX: some frame has old frame data.

    Is your LPFR register on the CCDC correct?  It's hard to tell if it is the data from a previous frame or if you are simply capturing an incorrect number of lines.

    Thank you, mdeneen.

    I will check the LPFR register, but the abnormal don't happen in all frame .

    On the other hand,  the separator is not always on the same position.

    In my example picture, the upper half is new frame (expected), but the down half is previous 3 frame data.

    I think that like the frame update speed is too slow, but i am not sure.
