I have a project where I want to experiment with a root complex design, but I only have a PicoZed 7015 SOM and V2 Carrier. Is it possible to put a root complex design on a PicoZed SOM and connect a PCIe endpoint with a female-female cable to the V2 Carrier card? Is there anything electrically wrong with that other than the lack of power rails provided to the second endpoint, or is that just impossible? I can look at getting the mini ITX board, but I'd rather use the equipment I have already if possible. Thanks!
