Maybe the packet then gets far enough into the IP stack to intercept it with raw sockets.
One last idea: You could try to enable IP Forwarding on Windows XP. HOWEVER I would not rely too much on that 'feature' as that is probably not intentional and Microsoft may change that behavior without notification. The other option would be to use Windows 7 as BOOTP server, as you said raw sockets do work there, even with the destination ip address of 0.0.0.0. However, I'm not sure if you will be able to establish a complete communication that way (delivering a firmware image to the DSP).
So, WinPcap sounds like a possible solution. No response is processed for this message and it is constructed in such a way that most if not all BOOTP and DHCP servers discard it. I have used RAW sockets to send/receive the packets."Ĭite: The Ethernet-ready announcement frame is made in the form of a BOOTP request so it can use a standard format. You can use PCAP library ( ) to achieve these functionalities (capture and send the packet). You will have to use a custom server which accepts all 0 as IP address."Ĭite TI Employee: "There is no detailed documentation on how to write the server. The DM648 BOOTP format is TI specific and will not work with standard BOOTP server. Other people seem to have the same problem and it looks like TI did it intentionally.Ĭite TI Employee: "Regarding the BOOTP packet.
