I am Developing Serial to Ethernet converter using coldfire v1 mcf51cn128cgt. I have ported freertos with lwip stack.
lwip initialization done successfully. But Program stuck at sys_mbox_fetch() in tcp thread for forever and also ETHER_EN bit of Ethernet control Reg[ECR] get clear. And Ethernet low level Communication stops unexpectedly.
Is there any idea why this is happening, Waiting for good answers.
