TM4C1294NCPDT: Custom board does not get IP address/ how to program MAC address

Prachi Patil

Part Number: TM4C1294NCPDT

I have a custom board of TM4C129NCPDT, I tried to dump the TCP echo example, but in the Board_initEMAC(); function,it goes to else if part and then to exit. I wanted to know how to program custom MAC address to a custom board to get IP address from DHCP.

Thanks.

Hello Techinspired,

You can use the LM Flash Programmer to program your own MAC Address into the TM4C.

Hello Ralph,

Thanks for your reply.

I programmed MAC address to my custom board, I've checked it by get current MAC utility in LM Flash programmer, it now gives me a MAC address, but still I'm not getting any IP address. What could be the possibilities for not getting IP address?

Regards.

Hello Techinspired,

I think that would deserve a new topic, and when making that new topic I would encourage to share more information about your setup, including how far into execution the firmware gets (like, are there any packets exchanged at all?), what your cabling for Ethernet is, and also if there are any deviation from Ethernet guidelines from: www.ti.com/.../spma056.pdf as those will be among the first questions asked.
