Looking for a cape board for beagleboard x15

We are using the beagleboard x15 for our project, but while waiting for our board design to complete and boards to arrive, our software team would like to test their software drivers where access is made to our board via GPMC and GPIO. Is there a cape board that can help us check our software drivers and make sure it is accessing the proper addresses and see the GPIO bits toggle and the GPMC bus access some memory. I have done a lot of searching and do not see any cape boards available other than an LCD EVM on TI’s website which seems to have an x15 equivalent integrated.
Thank you
