Can you tell me what this might be related to? Is this really a bug? Thanks!

Yes, in the example there is a bug in the interrupt handler. You cannot call printf() directly from an interrupt handler. Instead, you need to use either the FreeRTOS queue or event groups. You can see how to do this correctly in the example for tca95x5.

I'm leaving this issue open until I fix the bug in the mcp23017 example.

sazanof commented 5 months ago

Thank you. I think, my question is closed. I use code like this

static void IRAM_ATTR intr_handler(void *arg)
{

    if (!interrupt_running)
    {
        interrupt_running = true;
        xTaskCreate(read_interrupt, "read_interrupt", configMINIMAL_STACK_SIZE * 6, NULL, 5, NULL);
    }
}

and if I need to print - I use ESP_DRAM_LOGx functions
