I’m putting together an Arduino DHCP bootloader for the 5500. It works fine but on boot the initial DISCOVER packet is not sent immediately after the Sn_IR_SENDOK is received. It’s sent after about 10 seconds and I can see that the Link Status bit changes from 0 to 1 at about 5 seconds but even then it takes a while for the packet to be seen on Wireshark. After this everything clicks into place.
Is this behaviour expected? I have explicitly set OPMDC to 100T/Full/Auto-Disabled.
