RTOS/TM4C1294NCPDT: TCP ECHO program is not working with RJ45(in-built transformer).

Hello Shaheen

I am not sure at what stage of the IP address acquisition is the message "Service Status: DHCPC : Enabled : Fault : 002" generated. Did you check with TI-RTOS forum on why and when this error comes?

Can you use WireShark to confirm nothing is being sent (e.g. DHCP broadcast) or received from that device? I expect that nothing is going out and DHCP timer expires and gives the message.

Thank you for the reply.

I have seen only DHCP DISCOVER message in wireshark in case of (In-built transformer) RJ45 board.

whereas the device with (external transformer)RJ45 board shows both DHCP DISCOVER and DHCP REQUEST info

  Kindly guide me to the cause of this problem.

Hello Shaheen

A passing thought: Can you reprogram the MAC address of the failing board to be same as that of the Passing board?

Hello Amit,

You are right the problem is in MAC Address.

Thank you.

Hello Shaheen

Please check if the MAC address is an allocated MAC address to your organization and is properly recognizes by the switches and routers.

Ok.

Thanks & Regards,
