Problem about Using BF533 Silicon Revision 0.6

Hi, We are using BF533 for video compression. DMA data through the PPI port is used in our design. Both 16bit and 32bit DMA work well if we use BF533 Silicon Revision 0.2, 0.3 or 0.4. For Silicon Revision 0.6, the 16bit DMA works well, and we can get the correct image data, but if the 32bit DMA is used, we cannot get the correct data (dazzling and the fps decrease).

 

Can you tell me the possible reason, and the different between Silicon Revision 0.2 and 0.6?

 

Thanks!
