But the issue could be fixed using the scaling logic in DSS. > Please provide me the patch if this was solved. > I don't have a patch, but the procedure of getting this fixed is to - Enable Scaling block - Get BA0 and BA1 point to same location and modify the size register to avoid doing a interlaced scan. - Modify ACCU0 ACCU1 registers to tune in the performance. I don't have the register values handy, will try to get them and send it across. But with this you will loose down scaling capability. You will not see this flickering for a video as such it's only on static text images.
