Tool/software:
Hello,
I have designed a board that includes the Novatel OEM 7700 receiver (which has its own PHY). On the same board, I have added another PHY so that it can be connected via RGMII to an FPGA on a different board through a cable. Before I connect it, I want to perform a test to confirm that the design is correct. I have the devboard, specifically the DP83867ERGZ-R-EVM, and I have connected the RGMII pins. I connected the RXD0..3 pins from one board to the TXD0..3 pins on the devboard because all I need from the devboard is for it to pass the information so I can check with my PC to see if it works. The problem I’m facing is that it doesn't work at all, as if the information is not passing through the devboard. What can I do about this? Should I connect via JTAG? Do I need to set a specific mode on the devboard?
