Handling BOOTP 6474

Nicholas Sicalides

Hi,

I am able to get the 6474evm to generate a BOOTP packet. However, I am finding it difficult to actually read the packet. Using windows sockets and lwIP TCP/IP stack I find that the BOOTP packet doesn't make it through the stack. I can see it on a packet sniffer but would like to boot the DSP by responding to the packet.

I believe the packet is not making it through the TCP/IP stack because the source and destination IP are 0.0.0.0. I have 2 questions. Is there a way to change the source and destination IP address for the BOOTP packet(reviewing documenation I haven't found a way)? If not what recommendations does TI have to handle this packet?

Thanks

Hi Nick,

Yes the BootP packet is only a MAC packet and not a IP packet. You don't have an option to change the IP but I beleive that you can use WINPCAP to decode the packet to get the MAC address with whihc you can build you packet. I will see whether I can get some function in winpcap that you can use. but I beleive that you can easily find it in google search.

Thanks,

Arun.
