ESP32 CAM: gpio_install_isr_service failed (105)

Postby VadimKHL » Sat Mar 06, 2021 7:42 pm

Hello everyone!

There is a problem when initializing the camera:
E (1857) camera: gpio_install_isr_service failed (105)
E (1858) camera: Camera init failed with error 0x105

If you add a command before initializing the camera, this one:
gpio_install_isr_service(ESP_INTR_FLAG_IRAM);

The camera starts up, but with warnings:
E (1855) gpio: gpio_install_isr_service(438): GPIO isr service already installed
W (1856) camera: gpio_install_isr_service already installed

How to solve this problem?
Thanks to all!

It seems like have some GPIO ISR init happening in camera_init routine.
To be more specific, gpio_isr_register is the problem. One is telling that you want a per-pin gpio interrupt and another is telling that you want just one event handler happening when any gpio interrupt happen.

To avoid this you need to replace the gpio_isr_register for gpio_isr_handler_add, but I can't guide you through all steps because I'm still working on this.

Hi,

I also get this problem on Arduino IDE. when I creat firstly the interrupt for gpio_ISR and then init_camera() :
[E][camera.c:1327] camera_init(): gpio_install_isr_service failed (105)
[E][camera.c:1406] esp_camera_init(): Camera init failed with error 0x105

but I write these vice versa ,firsty init_camera() and then gpio_ISR(), :

Rebooting...

and then rebooting and rebooting again...

To get rid of this problem I tried to deinitialize the cam,but I can't use properly this function: esp_err_t esp_camera_deinit().

Just updating my journay with this error.

I'm using enc28j60 as ethernet connection interface. Looking a little deep on his example code available on espressif's repo on github, i found that inside esp-idf/examples/ethernet/enc28j60/main/enc28j60_example_main.c we have a ESP_ERROR_CHECK(gpio_install_isr_service(0)); where that according with the documentation is incompatible with gpio_isr_register() (that is callend on espCam logic).

So, to bypass that fact, i disabled the gpio_install_isr_service(0) on ethernet flow and inside esp-idf/examples/ethernet/enc28j60/components/eth_enc28j60/esp_eth_mac_enc28j60.c I replaced any interrupt pin initialization by a little task that constantly check if the interrupt pin is changing from high level to low level (falling edge)

When it happens is just calls enc28j60_isr_handler() passing the arg foward.

Isn't the best but it connect and use the camera at the same time.

It's a little bit instable yet, after a few minutes i get lost connection and reconnect doesn't happen. I'm still validating if it isn't my fault or if just a task checking the pin isn't good enough to get this interrupt interaction.
