I am Receiving a frame from a camera , at 30 fps . Which sends 768 packets per frame . I am loosing Packet n.o 80 to 100 randomly in every frame . Have a similar Application running on my PC which works fine .

As soon as i am connecting another switch between my evm and the camera there are no packets drop then , Can some one help me how to solve this issue ?

    Hello,

    ezsdk_5_04_00_11_dm814x is very old release.

    Do you observe the same problem with the latest release 5.05.02?
