Hi,

I'm currently working on Hercules TMS570LS3137 Evaluation board using CCS and HALcogen. I'm trying the attached Ethernet loopback program, but in PC's wireshark no data packets are receiving. Is there any way to check the data packets of Evaluation Board in PC. Is there any example program for Ethernet in UDP/TCP protocol for TMS570LS3137.5531.enet_loopback.docx

Hello,

I don't think the wireshark can capture the loopback data. You can try the LWIP active webserver at:

I tried the lwip demo, in that got the output via the terminal, but it came until the DEBUG - Setting up the link...SUCCESS. Then the reset button has been given, but it doesn't showing or sending any packets.

Note : Enabled the Ethernet on EVM by setting switch S2 bit4 to On

Are your PC and the TMS570LS3137 Evaluation board connected to the same ethernet router? The lwIP initialization starts the DHCP process to dynamically obtain an IP address. If the DHCP attempt fails and the static IP address is used, then the PC must be configured to be on the same subnet as the board.

Is there any way to implement UDP protocol in TMS570LS3137 without LwIP?

Yes. But we don't have UDP example code.
