xapp585 cameralink decoder 'one' pixel shift to right after the 16th pixel in the first line
I took the app note Xapp585 to build a Cameralink receiver and transmitter IP. I implemented the Cameralink receiver IP, it seems that work properly, except the first line. The others lines are received and decoded correctly. I have realized that, there is a problem in the first line. Up to 16th pixel (16 included) is received correctly. But after the this 16th pixel, 17th pixel is zero and then correct values comes. However, 17th pixel should have not to be zero. there is only 'one' pixel shift to the right, in only first line after the 17th pixel. I have used a FIFO, and I take fifo out to a Axi-Stream.
So what is the possible reason for this deterministic(it is seen all time ) error?
