TM4C1294KCPDT: TIDM-TM4C129POEAUDIO STOP

Part Number: TM4C1294KCPDT
Other Parts Discussed in Thread: TIDM-TM4C129POE

I posted the same content 4 months ago, but it has not been resolved, so I am posting the content again.

Provide case details or comments: Hello?
I have two TIDM-TM4C129POE modules.
I am testing by connecting an audio output(eg mp3) to the input of each module
and connecting an amplifier to each output.
The connection (CALL-RECEIVE) works well.

However, if you keep the call connected, one module will hang.
After a few seconds, minutes or hours of normal operation, one module hangs (system down).
Only one of the two modules is stopped. Stopped modules do nothing.
Audio output, no LED blinking, no touch screen input, etc. all do not work.

Version of program and source file in use:
TivaWare_C_Series-2.2.0.295
CCS version 6/9/10
opus version 1.1.2 / 1.1.5 / 1.2.1 / 1.3.1

Even if all CCS versions and all opus versions are combined and compiled, the result is the same.
The same goes for testing by changing modules.
It is being used without modifying the contents of the source file.

    Hi,

      Sorry, I have no such hardware with me and neither am I familiar with this application. When you said after a while everything will stop. That kind of lead me to think that the device is hanging. Are you able to find out if the processor is in some kind of fault. When you connect to the device with CCS, what do you see the processor is doing? Can you increase the stack size and rebuild the project again? A lot of time, a hanging problem is due to lack of stack size. Will you see any difference if you increase the stack size? But first of all, find out if the processor is trapped in a fault ISR.
