Hi, I'm working on a hardware watchdog by using the esp task watchdog (CONFIG_ESP_TASK_WDT=y in sdkconfig). I am having some problems with resetting the timer, because I keep getting the error 261, which is

/*   261 0x105 Requested resource not found */

. I init the watchdog, and add NULL as task which appears to be the entire toit task 🙂

esp_err_t err1 = esp_task_wdt_init(timeout_s, true);
  esp_err_t err2 = esp_task_wdt_add(NULL);

I have another function which resets the timer, and logs the rc to console

esp_err_t err = esp_task_wdt_reset();
  ESP_LOGE("Toit", "WDT reset: %d",err);

The restting looks like this in console:

E (689483) Toit: WDT reset: 0
E (689993) Toit: WDT reset: 0
E (690503) Toit: WDT reset: 261
E (691003) Toit: WDT reset: 261
E (691513) Toit: WDT reset: 0
E (692013) Toit: WDT reset: 261
E (692523) Toit: WDT reset: 261
E (693033) Toit: WDT reset: 0
E (693543) Toit: WDT reset: 0
E (694053) Toit: WDT reset: 261
E (733243) Toit: WDT reset: 261
E (733753) Toit: WDT reset: 261
E (734263) Toit: WDT reset: 261
E (734773) Toit: WDT reset: 261
E (735283) Toit: WDT reset: 0
E (735833) Toit: WDT reset: 261
E (736343) Toit: WDT reset: 0
E (736853) Toit: WDT reset: 261
E (737363) Toit: WDT reset: 261
E (737873) Toit: WDT reset: 261

But this is giving me far more errors than succesful resets. I wonder if anyone else has been playing around with this watchdog?
