Hi all, I'm working with SD card. When I push SD card in slot, it work fine. I want to LOG some error mess when SD card don't exist. I test this code and the result is my module reboot

Help me with this problem, I need to know when SD card isn't inserted and of course others function still have to work fine
Thanks for your interest

Here my sdcard_mount() func:

Code: [Select all] [Expand/Collapse]

static void sdcard_mount()
{
    /*sd_card part code*/
    esp_vfs_fat_sdmmc_mount_config_t mount_config = {
//#ifdef CONFIG_EXAMPLE_FORMAT_IF_MOUNT_FAILED
        .format_if_mount_failed = true,
//#else
//        .format_if_mount_failed = false,
//#endif // EXAMPLE_FORMAT_IF_MOUNT_FAILED
        .max_files = 5,
        .allocation_unit_size = 16 * 1024
    };
    sdmmc_card_t* card;
    const char mount_point[] = MOUNT_POINT;
    ESP_LOGI(TAG, "Initializing SD card");
 
    ESP_LOGI(TAG, "Using SPI peripheral");
 
    sdmmc_host_t host = SDSPI_HOST_DEFAULT();
    spi_bus_config_t bus_cfg = {
        .mosi_io_num = PIN_NUM_MOSI,
        .miso_io_num = PIN_NUM_MISO,
        .sclk_io_num = PIN_NUM_CLK,
        .quadwp_io_num = -1,
        .quadhd_io_num = -1,
        .max_transfer_sz = 4000,
    };
 
    esp_err_t ret = spi_bus_initialize(host.slot, &bus_cfg, SPI_DMA_CHAN);
    if (ret != ESP_OK) {
        ESP_LOGE(TAG, "Failed to initialize bus.");
        // ESP_ERROR_CHECK(ret);
    }
 
    // This initializes the slot without card detect (CD) and write protect (WP) signals.
    // Modify slot_config.gpio_cd and slot_config.gpio_wp if your board has these signals.
    sdspi_device_config_t slot_config = SDSPI_DEVICE_CONFIG_DEFAULT();
    slot_config.gpio_cs = PIN_NUM_CS;
    slot_config.host_id = host.slot;
    esp_err_t err = esp_vfs_fat_sdspi_mount(mount_point, &host, &slot_config, &mount_config, &card);
    //mount_card = card;
 
    if(err != ESP_OK){
        if (err == ESP_FAIL) {
            ESP_LOGE(TAG, "Failed to mount filesystem. "
                "If you want the card to be formatted, set the EXAMPLE_FORMAT_IF_MOUNT_FAILED menuconfig option.");
        } else {
            ESP_LOGE(TAG, "Failed to initialize the card (%s). "
                "Make sure SD card lines have pull-up resistors in place.", esp_err_to_name(err));
        }
        // ESP_ERROR_CHECK(ret);
    }
    sdmmc_card_print_info(stdout, card);
    
    ESP_ERROR_CHECK(start_file_server("/sdcard"));
    //vTaskDelete(NULL);
}
