As I am debugging my RTWDOG timer on an RT1020 I am running into an issue. Whenever I run my tasks as I expect and refresh my RTWDOG, they work fine. However, if I forcefully try to have the RTWDOG fail and reset my MCU, it fails and gives me this error message:
I am debugging using "Debug using LinkServer probes" and flashing the code to my RT1020 board, and I initialize the RTWDOG in my main() function after the Board config functions and before I create my freeRTOS tasks.
This is my current RTWDOG configuration, where I set debug and the other debug configurations to false, as I am flashing to my board:
uint16_t temp;
/* When system is boot up, WDOG32 is disabled. We must wait for at least 2.5
* periods of wdog32 clock to reconfigure wodg32. So Delay a while to wait for
* the previous configuration taking effect. */
/* DELAY_TIME = 0x140 ~ 2.5 seconds */
for (temp = 0; temp < DELAY_TIME; temp++)
{
__NOP(); // NOP = no operation
}
/**
* config->enableRtwdog = true;
* config->clockSource = kRTWDOG_ClockSource1;
* config->prescaler = kRTWDOG_ClockPrescalerDivide1;
* config->workMode.enableWait = true;

* config->workMode.enableDebug = false;
* config->testMode = kRTWDOG_TestModeDisabled;

/* get the default configuration for the rtwdog as listed above */
RTWDOG_GetDefaultConfig(&config); // get the default configuration of rtwdog

*/
config.timeoutValue = 0x0180U; // set the timeout value to 3 secs for prescaled 32kHz clock1
config.prescaler = kRTWDOG_ClockPrescalerDivide256; // prescaler to increase the timeout value ((32.768 * 10^3) / 256)
config.workMode.enableWait = false;
config.workMode.enableDebug = false;
config.workMode.enableStop = false;
config.enableUpdate = true;
config.enableInterrupt = true;
/* initialize the rtwdog timer.
* To be called in main()
*/
RTWDOG_Init(RTWDOG, &config);
What can I change to have my RTWDOG reset my MCU automatically and not give me the thread suspension issue? I based my implementation on the rtwdog example provided by the SDK, and after I ran that I got the same thread suspension. Is it an issue with how I am debugging or something in the code is configured incorrectly?
