Intellectual 560 points

Part Number: TM4C1294KCPDT

Hi,

In one of the project we need to send adc data continuously to Ethernet. and code is working. Issue is that after a long time(nearly 10-12 hours and that is random, some time early 4-5 hours)  somewere MCU stuck and disconnects TCP connection and entire code stops working , even adc aquisition also. and that too withought giving any error. We just want do auto connect feature and so that data transfer remains continuos.

Device is TCP client , and PC act as a TCP server, we are using Hercules software for TCP connection test.

Ti RTOS :- 2.16.01.14

Compiler:-  GNU 7.2.1(linaro)

 

Please Help

Regards

    If you connect to the target with the debugger, can you tell where the processor is stuck at?

    Which TCP client application are you running? Did you create your own or did you reference some TI-RTOS examples?

    If you run the same application on the LaunchPad, do you see the same issue after some hours?
