I am trying to make a simple vdma test demo on zedboard.
Here is my steps.I want to send my own picture(32-bit per pixel) for FPGA processing.
1. I read my own picture to memory and copy them to DDR.
2. Using video dma core to send the input stream from DDR to my own pcore;
3. Samely, recieve the input stream from my pcore to DDR;
4. Finally, Write the output stream from DDR.
But i found the results in the bottom few lines are not proper, always comes with paceket loss?
Any ideas to fix this bug?
