Since wifi module of TX2 is not stable enough, we add another wifi module with PCie interface on our custom board. We config USB lane mapping #4 and use PCIe#1_0(PEX2 Lane 3) to connect a wifi module with pcie interface.
Sometimes we can detect pcie chip by lspci but most of time we got errors as below repeatedly. Is it a hardware problem or kernel issue?
