UDP programming in TMS570LS3137

Hello Abhijith,

There is an example LWIP project on the Hercules Wiki located here: processors.wiki.ti.com/.../HALCoGen_Ethernet_Driver_and_lwIP_Integration_Demonstration

It is primarily a webserver operating with TCP/IP but has UDP support as well with some modifications.

Hi ,i

       Thank you for the reply, I have been trying with one example and i am able to connect socket but data transfer  is not happening . Can you just guide us with this ?. i am attaching the project .

Regards

Hello Abhijith,

Have you had a look at this post? They have worked through the UDP communication question and have code posted that might help.

In addition, I have also forwarded your post to one of our EMAC experts so that they can provide more assistance/guidance.

Dear Chuck,
Did your EMAC experts replied my post?. I need one example which shows receiving and sending packets from/to host. now this has become bottle neck as we are running out of time . The project is completed because of this we are stuck .

Abhijith,

Again, my apologies for the lack of response on this topic. I will escalate this issue to get you more adequate support.

Hello Abhijith,

Unfortunately, we cannot support this activity. The device is capable of communicating using UDP and we have others that have been able to get it working but we have no one on the team with experience with this communication format. Perhaps on reviewing other posts on the E2E you will be able to work through the issues you face with your application.
