Using two Ethernet Interfaces with UDP and the NDK on C6678

Hi all,

I am currently looking into transmitting out two ethernet ports with UDP for a project, using the NDK on a C6678.  I believe I have pieces set up correctly (withing app.cfg, two IP interfaces on different addresses with different IDs). 

However, it seems that no matter what I do, I cannot seem to get transmission to work properly.  It seems that whatever the second interface definition is takes precendence, and all transmissions originate from that (the second) port.  eth0 

When I start up the project, I do see that two interfaces are being added with the expected IPs (and when I telnet into the chip from the second port, I am able to see both interfaces), but it seems that I am only ever able to use the second.

Is there any guide out there or any information to help me out on this?  I figure I am missing something relatively basic, and would appreciate any help. 

I am sure I missed vital points on this, so if you have any questions, just let me know and I will get back to you as soon as I can.

    Hi,

     We are trying to use both ethernet ports in our board. We are not able to add mac address for the second port if port one is configured and working. Could you able to share the information of using two ethernet ports parallel y. It would be really helpful for us.

     

    Thanks
