We are looking at using the FMCOMMS8 with a host board made by Alinx. After inspecting the schematics for the FMC HPC connector, we have observed one issue. We are wondering if this is a problem.

The host boards we are considering, do not have a connection for K4 or K5 on the FMC. Is this a problem? The host boards do have connections for J2 and J3.
