I designed my own card into the M.2 slot because I need three ethernet ports. I use PCIe SWITCH PI7C9X2G404EL ----- 3x ----> x1 to ETH.
During debugging, I found out that I could see some communication and clock on the physical layer. Unfortunately, in dmesg and lspci, I see no indication that the card is initializing. Do you have any experience with this switch? Is there anyone who has used it and would advise me?
The switch doesn’t use the CLKREQ pin, so I didn’t use it at all. Does it make sense to edit something in the device tree module, if so what?
Thanks for any advice.
