IBERT: BER measurement looks good, but eye scan is not working
I am attempting to get an eye scan from an MPSoC system. I have generated an IBERT image and have been able to get the MGT link up and quasi error free. If I inject errors I see them detected as I would expect.
However, when I run the eye scan I see nothing but a BER of approx 1/2. Any idea why this would be happening? It's as if the MGT receiver isn't locking when in eye scan mode. A screenshot of my eye scan result is attached.
