srioIpcChipToChipExample cross-connection board for EVM

I have two TMDXEVM6678L boards and need to run the srio chip-to-chip example which is intended to run with two EVMs with their SRIOs cross-connected via some kind of breakout boards. However, I don't have any such cross-connection board.

So my question is; Is it possible to purchase such needed breakout-board(s) from TI or Advantech? Or, can anyone help me with needed instructions/drawings on how to build one?

BR, Marty
