ES32C3 - Guru Meditation Error: Core 0 panic'ed (Interrupt wdt timeout on CPU0).

[henryli]

使用ES32C3 master分支，增加一个GPIO中断，代码如下：

if (gpioext_obj[index].init_param->int_pin != PIN_UNASSIGNED)
{
gpio_config_t io_conf;

ESP_LOGE(TAG, "%s: int io %d ", __func__, gpioext_obj[index].init_param->int_pin);

//enable interrupt
io_conf.intr_type = GPIO_INTR_ANYEDGE; /* falling */
//set as input mode
io_conf.mode = GPIO_MODE_INPUT;
//bit mask of the pins that you want to set,e.g.GPIO18/19
io_conf.pin_bit_mask = 1 << gpioext_obj[index].init_param->int_pin; /* GP19 */
//disable pull-down mode
io_conf.pull_down_en = 0;
//enable pull-up mode
io_conf.pull_up_en = GPIO_PULLUP_ENABLE;
//configure GPIO with the given settings
gpio_config(&io_conf);
//change gpio intrrupt type for one pin
gpio_set_intr_type(gpioext_obj[index].init_param->int_pin, GPIO_INTR_ANYEDGE);
//install gpio isr service
gpio_install_isr_service(0);
//hook isr handler for specific gpio pin
gpio_isr_handler_add(gpioext_obj[index].init_param->int_pin, drv_gpioext_irq_cbFxn, (void*)index);


}

static void drv_gpioext_irq_cbFxn(void *arg)
{
GPIO_EXT_CHIP index = (GPIO_EXT_CHIP)arg;
MC_pub(EVENT_GPIOEXT, EVENT_GPIOEXT_ARG_INT, 1, index);
}

在多次中断后出现

但是中断处理只是发送了一个消息，没有其他处理，怎么会导致timeout出错？

你看下这个文档：https://docs.espressif.com/projects/esp ... /wdts.html
另外，需要看下你 MC_pub 里的实现。你可以试着把 CONFIG_ESP_INT_WDT 放大看看情况。
