Guru Meditation Error: Core 0 panic'ed (Interrupt wdt timeout on CPU0) when using 12v supply

[Isaac_Atia]

I know this question has been asked frequently but somehow they don't provide me with the answers I seek so I am asking again.

I have an application running on a custom board with ESP32-S3-WROOM-1-N16R2 and some other sensors and power supply modules. I designed my power supply in such a way that I can power the board with either 5v from a usb supply or 12v external supply. Either way I have two regulators onboard to convert either of the supplies to 3.3V for the main chip and low power sensors and 3.8V for my cellular module as it requires high power. I also have a power mux so in event that one is writing code for the high power cellular module and would like to debug, they can have both 5v supply and 12v external supply connected and the mux will prioritize the 5v supply and convert that to 3.3v for the board + low power sensors while the 12v will be stepped down to 3.8v for the cellular module. However if you have only usb power connected, you only get 3.3v without the 3.8v and when you have the 12v external supply supply connected you get both the 3.3v and 3.8v respectively. The reason for this is because the board will be used in a 12v environment in the long run. I have added this circuit as an attachment.

I'm writing my code using esp-idf port of freertos with all tasks running on cpu_0, and, when I power the board using 5v/usb supply onlu the code runs as expected as seen from the output below;

However when I include the 12v external supply, still running the same code with absolutely no changes, I run into an error as shown from the debug message below and error keeps on looping;

Has anyone experienced a similar situation and how did you go about solving it.

[ESP_Sprite]

Can we have a look at your code? Specifically, are you using GPIO interrupts?

[Isaac_Atia]

Can we have a look at your code? Specifically, are you using GPIO interrupts?

For reasons beyond my control I am not permitted to show the code because it will end up in a product. However to answer your question, yes I am using GPIO interrupts (2 infact).

An observation I also made recently after debugging further, I realized that by removing the GPIO interrupts, the code works just fine and only produces the error up when the GPIO interrupt is present.

[ESP_Sprite]

Are you setting up the GPIOs (and enabling interrupts on them) before you install the GPIO driver that handles those interrupts, perhaps?

Are you setting up the GPIOs (and enabling interrupts on them) before you install the GPIO driver that handles those interrupts, perhaps?

Yes exactly. Also I have gotten permission to share part of the code as long as it isn't anything critical. So here is how I am setting and installing the gpio with interrupt.

Code: Select all

gpio_config_t intr_conf = {
        .mode = GPIO_MODE_INPUT,
        .pin_bit_mask = (1ULL << ON_SIGNAL) | (1ULL << COIL_OUTPUT),
        .intr_type = GPIO_INTR_ANYEDGE,
        .pull_down_en = GPIO_PULLDOWN_DISABLE,
        .pull_up_en = GPIO_PULLUP_DISABLE};
    ESP_ERROR_CHECK(gpio_config(&intr_conf));
    // gpio_set_intr_type(ON_SIGNAL, GPIO_INTR_LOW_LEVEL);
    ESP_ERROR_CHECK(gpio_install_isr_service(ESP_INTR_FLAG_LEVEL1));
    ESP_ERROR_CHECK(gpio_isr_handler_add(ON_SIGNAL, ignitionOff, (void *)ON_SIGNAL));
    ESP_ERROR_CHECK(gpio_isr_handler_add(COIL_OUTPUT, ignitionOff, (void *)COIL_OUTPUT));

Flip those. Install the ISR handlers first, and only afterwards configure the GPIO pins. Otherwise the GPIO interrupt will trigger without anything acknowledging that interrupt, and that leads to issues.
