想要用看门狗实现程序跑飞复位的功能,看了一下以前的帖子,说任务看门狗默认不会复位,需要勾上Invoke panic handler on Task Watchdog timeout
这个选项,我勾上了。尝试循环喂狗10次后不喂狗,看到的现象和我想象中的复位不太一样? 一直在反复打印这些信息: E (23247) task_wdt: Task watchdog got triggered. The following tasks did not reset the watchdog in time: E (23247) task_wdt: - reset task (CPU 0/1) E (23247) task_wdt: Tasks currently running: E (23247) task_wdt: CPU 0: IDLE0 E (23247) task_wdt: CPU 1: IDLE1 E (23247) task_wdt: Print CPU 0 (current core) backtrace Backtrace:0x400D4644:0x3FFBE370 0x4008290D:0x3FFBE390 0x4019B87B:0x3FFBBD00 0x400D491E:0x3FFBBD20 0x400902FD:0x3FFBBD40 0x4008F965:0x3FFBBD60 0x400d4644: task_wdt_isr at C:/Users/15459/esp-idf/components/esp_common/src/task_wdt.c:187 0x4008290d: _xt_lowint1 at C:/Users/15459/esp-idf/components/freertos/xtensa/xtensa_vectors.S:1105 0x4019b87b: esp_pm_impl_waiti at C:/Users/15459/esp-idf/components/esp32/pm_esp32.c:501 0x400d491e: esp_vApplicationIdleHook at C:/Users/15459/esp-idf/components/esp_common/src/freertos_hooks.c:63 0x400902fd: prvIdleTask at C:/Users/15459/esp-idf/components/freertos/tasks.c:3386 (discriminator 1) 0x4008f965: vPortTaskWrapper at C:/Users/15459/esp-idf/components/freertos/xtensa/port.c:143 E (23247) task_wdt: Print CPU 1 backtrace Backtrace:0x40081BE7:0x3FFBE970 0x4008290D:0x3FFBE990 0x4019B87B:0x3FFBC460 0x400D491E:0x3FFBC480 0x400902FD:0x3FFBC4A0 0x4008F965:0x3FFBC4C0 0x40081be7: esp_crosscore_isr at C:/Users/15459/esp-idf/components/esp32/crosscore_int.c:80 0x4008290d: _xt_lowint1 at C:/Users/15459/esp-idf/components/freertos/xtensa/xtensa_vectors.S:1105 0x4019b87b: esp_pm_impl_waiti at C:/Users/15459/esp-idf/components/esp32/pm_esp32.c:501 0x400d491e: esp_vApplicationIdleHook at C:/Users/15459/esp-idf/components/esp_common/src/freertos_hooks.c:63 0x400902fd: prvIdleTask at C:/Users/15459/esp-idf/components/freertos/tasks.c:3386 (discriminator 1) 0x4008f965: vPortTaskWrapper at C:/Users/15459/esp-idf/components/freertos/xtensa/port.c:143 |
