Hello,
I need to make sure that my LPC2478 will configure its DHCP only after the physical insertion of the Ethernet cable into the controller (it seems that TCPNet cannot handle a situation where a DHCP enabled controller is startup without a network connection, thus the need to configure TCPNet again or for the firs time once the cable is inserted. Note: of the controller already got an IP address, then had his cable disconnected, there is no problem). It seems that simple interrupt detection won't do the job. Any ideas?
I recall this issue a while back and asking Keil at the time, in the end i monitored the Link State and speed lines between the transceiver and the magnetics with a few spare GPIO.
cheers Darren
