Error:GPIO isr service already installed

Postby nirmeshru » Sun Sep 05, 2021 6:56 pm

Hi,

I modified the switch example and enabling two GPIO pins using two switch buttons.
I am using the ESP32 custom board and after loading the program getting the below error.

# switch button
#define BUTTON_GPIO_1 21
#define BUTTON_GPIO_2 17
#define BUTTON_ACTIVE_LEVEL 0

/* This is the GPIO on which the power will be set */
#define OUTPUT_GPIO_1 14
#define OUTPUT_GPIO_2 27


E (887) gpio: gpio_install_isr_service(438): GPIO isr service already installed

can you please help on this.

Thanks,
Nirmesh

From what you posted I can only see that you have defined GPIO pins. Can you post the code where you configured GPIO?
You need to have something similar with:

Code: Select all

    button_handle_t btn_handle_1 = iot_button_create(BUTTON_GPIO_1, BUTTON_ACTIVE_LEVEL_1);
    button_handle_t btn_handle_2 = iot_button_create(BUTTON_GPIO_2, BUTTON_ACTIVE_LEVEL_2);
    if (btn_handle_1) {
        /* Register a callback for a button tap (short press) event */
        iot_button_set_evt_cb(btn_handle_1, BUTTON_CB_TAP, push_btn_cb_1, NULL);
        /* Register Wi-Fi reset and factory reset functionality on same button */
        app_reset_button_register(btn_handle_1, WIFI_RESET_BUTTON_TIMEOUT, FACTORY_RESET_BUTTON_TIMEOUT);
    }
    if (btn_handle_2) {
        /* Register a callback for a button tap (short press) event */
        iot_button_set_evt_cb(btn_handle_2, BUTTON_CB_TAP, push_btn_cb_2, NULL);
    }
    // Configure the GPIO
    gpio_config_t io_conf = {
        .mode = GPIO_MODE_OUTPUT,
        .pull_up_en = 1,
    };
    uint64_t pin_mask = (((uint64_t)1 << OUTPUT_GPIO_1) | ((uint64_t)1 << OUTPUT_GPIO_2));
    io_conf.pin_bit_mask = pin_mask;
    gpio_config(&io_conf);
I hope I managed to help you.

@codorstelian Thanks for the help.
I have defined the gpio like as you suggested but still getting the same error.
E (906) gpio: gpio_install_isr_service(438): GPIO isr service already installed

I am using the below code.

Hi Nirmesh,

If I remember correctly, that is more like a warning rather than an error. Do you face any actual issues while using the GPIO.

Regards,
Piyush

I have tried to reproduce the error and it appears when I add a second iot_button so I think this error is caused from the button library located in esp-rainmaker/components.

Hi Piyush,

Actually when I tried two switches then there is no functional issue only getting the above error (warning).
but I am working for four switches so whenever I am trying with four switches getting below error and some watchdog task trigger and device start rebooting in a loop.

serial log -

Hi Nirmesh,

Can you share the code snippet for this new issue?

Sure Piyush.

"E (906)" indicates it's an error message.
If it is indeed harmless, please convert it to warning message (W).

Fyi, this is indeed an error, caused by a few of our components not working well together. The message you see is the only result of this error, as the GPIO API happens to catch it, but even if it is otherwise harmless, it is an error regardless and we will take measures to fix it.

(I'd like to also state that in general, it's not really our policy to generate error messages like that that you can 'just ignore', even if it happens to work out here.)
