After running for a few hours, the system freezes and the watchdog restarts

How to analyze where the stuck is and whether the stack information can be printed

I have done an experiment before, using a low power consumption example, close the SD card (SDFatFS_close) before low power consumption enters, and open the SD card (SDFatFS_open) after low power consumption exits,

there will be stuck phenomenon, the phenomenon is very similar , I don’t know if it is caused by the same reason

Hello Ken,

What "system" are you referring to? What specific TI device?

Please provide more detail.

Thank you,

~Leonard

Hi Ken lai,

I suggest you add debug printing to your application so you can determine what is happening in the application when it gets stuck. You can also use the ROV to monitor the stack and threads, but this will not work in low power modes. See Task 2 of this training: dev.ti.com/.../node

Best regards,

Sarah

hi Sarah:

The stuck position of the printed information is not fixed every time. Sometimes after the SD card is read and written, sometimes in the sleep function,

do I need to connect to the emulator when I use ROV? I am using CCS Version: 10.1.0.00010, What kind of emulator should I use, thank you!

Hi Ken lai,

You can use the XDS110 that is on the CC32xx LaunchPad. You plug in the LaunchPad, start a debug session, and open ROV. The training I linked in my previous reply should include all the steps.

Best regards,

Sarah

Hi Sarah:

I am purchasing XDS110, I will consult you again if I encounter debugging problems later, thank you!
