Steps to reproduce.

I am trying to get a CC1101 chip working with an ESP32. Using ESP-IDF plugin for VsCode.

gpio setup:

bool          bRet    = true;
        gpio_config_t gpioConfig;

        gpioConfig.intr_type    = GPIO_INTR_LOW_LEVEL;
        gpioConfig.pin_bit_mask = 1 << m_deviceConfig.RxPin;
        gpioConfig.mode         = GPIO_MODE_INPUT;
        gpioConfig.pull_up_en   = GPIO_PULLUP_DISABLE;
        gpioConfig.pull_down_en = GPIO_PULLDOWN_DISABLE;

        ESP_LOGD(TAG, "%s gpioconfig pin mask is 0x%0X", __FUNCTION__, (int)gpioConfig.pin_bit_mask);
        CERA(gpio_config(&gpioConfig));

        CERA(gpio_install_isr_service(0));

        CERA(gpio_isr_handler_add(m_deviceConfig.RxPin, gpioISR, this));

ISR:

void IRAM_ATTR CC1101Device::gpioISR(void *thisPtr)
    {
        /*CC1101Device *That   = static_cast<CC1101Device *>(thisPtr);
        uint32_t      ignore = 0;
        xQueueSendFromISR(That->m_ISRQueueHandle, (void *)&ignore, NULL);
        */
    }

Please note that every single line in the ISR is commented out.

The problem I was actually trying to solve is that I am not able to get any interrupts at all, even though I'm fairly certain the CC1101 is set up correctly.

In playing with various interrupt types, I finally tried LOW_LEVEL and hit this crash every time I run the code.

Any ideas ?
