TWR-K65F180 UDP echo example: it doesn't work!

Hello community,


I have big problems in communicating with my twrk65f180m board using UDP echo example present in KSDK_1.3.0 (it's the "lwip_udpecho_demo" example under "c\Freescale\KSDK_1.3.0\examples\twrk65f180m\demo_apps\lwip\lwip_udpecho_demo\...").


I am using MQX RTOS and KDS IDE (so I chose the proper UDP echo example under the path mentioned above).



Sending a ping message from the PC, I cannot communicate with the twrk65f180m while it is running this example. The board is not receiving ANY data from the PC (I couldn't block the code with any breakpoint then).



I sent a "ping" to the board from the Windows command console (as explained in "Kinetis SDK v.1.3 Demo Applications User's Guide.pdf"). I configured my PC with the fixed IP address =, Subnet mask = and Default gateway = I also tried to configured the PC with Default gateway = (i.e. same of the IP address). Here attached you can find a screenshot of my LAN configuration. The software in the tower board is not giving any positive answer to the ping message

I tried to do the same thing with the ping example. Same result, no answer to a ping message.



Please, can anyone tell me how to make this example working on twrk65f180m?


Thanks so much for your
