I try to modify the DMA tutorial from the website below:
What I want to do is make a 3*3 convolution in PL and use DMA to send data between PS and PL.
My design is setup as below:
When I send the data below some specific range, the design works correct. When i send above the specific range, the input data is fine at the first time but missing some value when I run again. The DMA stuck at sendchannel when i re-run many time.
Do I setup wrong or i should re-design my convolution? It seems to work well if the input data is within the range.
