C2000-DIGITAL-CONTROL-LIBRARY: 28388 CM udp_rx_callback not working.

Hi,

The UDP example expects the keywords 'START' and 'STOP' to start/stop the communication. Pls try it out.

Best Regards

Dear Siddharth Deshpande

I entered "Start" or "Stop" command, but it doesn't work.

I entered the ping command on the cmd screen, but there is no response.

In my opinion, it seems that the Ethernet driver has not been initialized. What part should I check?

Hi ,

Pls refer this post and check if the setup is correct

I checked your answer.
CPU1-cm_common_config_c28x.out
=> #define ETHERNET (main.c)
AM-enetlwip_udp.out

However, I sent the "START" command, but the "Connected_udp_28000" variable does not change to True.

The problem I have is not resolved yet.
No response from ping to 1.192.168.0.4.
2.udp_rx_callback does not work.
=> When a variable declared as a global variable in the udp_rx_callback function is increased, the variable does not increase.

Thank you for your help in resolving the issue.

Hi, 

What is the IP address of the PC that you have configured ?  It should be in the same network as the f2838x's network. 

Can you debug by halting  the CM core  to see call stack and the execution is stuck at?

Best Regards

 Hi,

A video of the test environment is attached.

As you said, I configured the network the same.

But ping still doesn't work.

also, when i debug cm, show popup "_JobHardwareBreakpoint.....". 

How to debug cm project?

Hi,
After running C28x as you said, I ran CM core.
The results were successful.
Ping is normal, and "START" and "STOP" commands are working.

There was no problem when C28x and CM were loaded like the video for the LED example. Can you tell me why this problem occurs depending on the order of loading the executable file?

Hi
Thank you so much for your help.
