Using median filter 2D in sopcbuilder

I try to connect the SGDMA's Avalon Streaming source to the median filter 2D's Avalon Streaming sink by SOPC.I have added a timing adapter between SGDMA and median filter 2D,

But I got an error like that:

Error: timing_adapter.out/my_alt_vip_med.din: The source has a startofpacket signal of 1 bits, but the sink does not.

Error: timing_adapter.out/my_alt_vip_med.din: The source has a endofpacket signal of 1 bits, but the sink does not.

I didnot find an adapter in SOPCBuilder to implete the convertion above.

Who can tell me how to next ?

Thanks very much in advance !

Regards ,

Rebecca

    Hi Rebecca;

    I have the same design as you, I want to bufferize the video data into DDR2 using the SGDMA core but without success, I got an overflow on my CVI and the endofpacket of the first frame earlier,

    do you have any idea about that ?

    thank you.
