Hi, I did my first PCBA with Ethernet interface using TLK106 RMII, I followed all suggestion for schematic and layout except the serial termination resistors( I used 10 ohm instead of 33 ohm as suggested by the TI) between the PHY and MAC
, it can start well by initializing the PHY, I can write the PHY registers, but the loopback and ping tests didn't work, For ping test, I can see some ARB received in my laptop each time I ping, but I couldn't get the ICMP after it. For loopback, I (think) the MAC couldn't send out the frame correctly, so loopback also failed, The MAC original EVB is using KSZ8081MNXRNB PHY, so that makes a conflict that can make the MAC unable to send the frame out, or may be a clocking problem! (already changed to the correct PHY address and register values). apricate your help.
