Iam trying to use embeddedartist's easy web example.

in "ethmac.c" ->Init_EthMAC(void) they configure the mac with "LPC_EMAC->Command" if i remove that line the code runs fine, but ethernet dosent work for obvious reasons.
if i leave the code as is the system goes into some sort of "limbo-mode" and i have to use ISP to reset it..

iam using the code red tool chain and my phy is a lan8720, on a custom board, see attachment for code and schematic.
