Hi Charles, Could you try 100MB connection? Either connect the Rock64 to 100Mb switch or connect it to the FreeBSD box directly and on the box's side run this command: ifconfig IFACENAME media 100baseT mediaopt full-duplex I wonder if link speed makes any difference. This looks suspiciously like a problem I had with RK339, where tx_delay/rx_delay was not set properly. And if I read the code correctly, our driver does not set those values yet. -- gonzo
