lock_acquire_generic

[Vaibhav02]

I am trying to erasing nvs on gpio ISR. I have write the below code.

Code: Select all

static void IRAM_ATTR gpio_isr_handler(void *arg)
{
    uint32_t current_time = xTaskGetTickCountFromISR();
    // Debounce: Only process if enough time has passed since the last interrupt
    if ((current_time - last_interrupt_time) > (3000 / portTICK_PERIOD_MS))
    {
        // button_state = true;
        esp_err_t err = nvs_flash_erase();
    
        if (err == ESP_OK) {
            ESP_LOGI("NVS", "NVS flash erased successfully.");
        } else {
            ESP_LOGE("NVS", "Failed to erase NVS flash: %s", esp_err_to_name(err));
        }
        last_interrupt_time = current_time;
    }
}

Below error comes to me for above code. How can I resolve this error.

There's very little you can do in an ISR; specifically you can't do anything that can block, and I guess NVS calls can block. The way to solve this is to use the ISR to set something (a semaphore, task notification, whatever) that signals code running in an actual task (not in an ISR) to do the erase.

I guess logging may block too ("This function or these macros should not be used from an interrupt.").
If you really have to log from an ISR, consider using ESP_EARLY_LOGx() or esp_rom_printf().
