IWR6843ISK-ODS: Watchdog problem

Hello,

Can you please confirm which version of the toolbox you are using and which lab and files you are looking at?

Thanks,

Jackson

HI，

The 3D people counting project in version 4.6 is used。

I'm not sure I understand what your question is. This is a function you have implemented in the people counting demo?

Please make sure you have seen the test code implementation of the watchdog in 6843 at the below path.

"C:\ti\mmwave_sdk_03_05_00_04\packages\ti\drivers\watchdog\test\xwr68xx"

HI，

My watchdog initializes as described above and basically runs as a routine. I added a summation variable to the watchdog callback function, then printed the value through a serial port in another task, and found that the value did not change, indicating that the watchdog was invalid.

Hello,

Are you able to run the test code and verify the callback interrupt is triggering. I don't see anything different, other than maybe it isn't linking the callback function correctly. Can you debug and verify that the watchdogCallback pointer is pointing to the correct function?

Regards,

Jackson

HI、

As for how to run the test code as you mentioned, I initialized it according to the test code.

Hello,

What does your watchdog callback function look like?

Regards,

Jackson

Hi,

This is the watchdog callback function.The main reason is that no callback function is fired.

void mbRadar_watchdogInit(void)
{
    Watchdog_Params     watchdogParams;

    /* Initializa the Watchdog driver */
    Watchdog_init();

    /* Initialize the Watchdog driver default parameters */
    Watchdog_Params_init(&watchdogParams);

    gWatchdogInt = 0;

    watchdogParams.resetMode = Watchdog_RESET_OFF;
    watchdogParams.callbackFxn = watchdogCallback;

    watchdogParams.debugStallMode = Watchdog_DEBUG_STALL_ON;
    watchdogParams.windowSize = Watchdog_WINDOW_100_PERCENT;

    /* texp = (DWDPRLD + 1) x 8192 / RTICLK. if RTICLK = 200MHz then 255 means 10.5ms .*/
    watchdogParams.preloadValue = 255;
    watchdogParams.socHandle = gMmwMssMCB.socHandle;
    watchdogParams.esmHandle = gMmwMssMCB.esmHandle;
    /* Open the Watchdog driver */
    watchdogHandle = Watchdog_open(0, &watchdogParams);
    return;
}
static void watchdogCallback(Watchdog_Handle handle)
{
    Watchdog_ResetMode  resetMode;

    if(gsensorState != sensorStop)
    {
        gWatchdogInt++;
    }

   Watchdog_clear(watchdogHandle);
    if (gWatchdogInt >= 30)
    {
        resetMode = Watchdog_RESET_ON;
        Watchdog_control (watchdogHandle, WATCHDOG_CMD_RESETMODE, (void* )&resetMode);
    }

    return;
}

Have you tried including the debug statement from the test program to make sure the watchdog opens correctly? And have you made sure that the initialization is being called correctly and getting all the way through init?

Thanks,

Jackson

Hi.

Please help me to check whether the initialization function and the callback function are correct. First, I add a log print to the initialization function. Once the program runs, I can see the log output through the serial port. This indicates that the initialization function has been executed. I don't quite understand what you mean by your last sentence. The initialization function is placed at the end of the initTask.
