AFE7920EVM: AFE7920 serdes eye incomplete

Part Number: AFE7920EVM

Dear, I am testing the Serdes Eye feature using an AFE7920EVM board.

I am using both a Latte based script containing 'AFE.JESD.SERDES[0].getSerdesEye() , and a self written embedded application based on CAFE::tiAfe79_SerDes.c::getSerdesEye().

In both cases a part of the eye diagram seems missing:

Latte output:

Output of self written embedded application:

There seems to be missing data on the left and rigth side of the graph.
Is this expected? What can be the cause of this? How could I fix this?
