I am trying to establish an Aurora interface between to boards. I have two identical HTG-830 boards with SFP+ FMC boards on them. I have set up the Aurora IP the same on both boards..
Both boards work with an optical loopback cable. However, when I connect the boards together with an optical cable, I do not get a LANE-UP or CHANNEL_UP. I have tried different cables, different FMC boards, single SFP's, QSFPs... always the same. Any ideas what the problem could be or where to start looking.

I don't think so. I also tried two FMC boards with a single SFP+ transceivers that I have used in the past with an Aurora 8b/10b design on a VC709 and it had the same behavior.

I have "memory" of there being a minimum data rate that the 64/66 worked at, below that the recommendation was to use 8/10,
but I can't find the reference.
Have you trawled through the answer records for the core,
