SD Card example is not working

[Rajkumar181]

Hello,

i tried all possible think, what you gave in example ,but still it is comming same error.
"I (10268) example: Using SPI peripheral
E (10268) example: Failed to initialize the card (259). Make sure SD card lines have pull-up resistors in place."
Please suggest to me what to do now?

Hello,

I retried the read and write the data into sd card. and i am success to read the data from SD card but the problem is , while writing the data into sd card. It is able to create a file but it is not writing on that.

My code :

Code: Select all

    sdmmc_host_t host = SDSPI_HOST_DEFAULT();
    host.slot = VSPI_HOST;
    host.flags = SDMMC_HOST_FLAG_SPI;
    host.max_freq_khz = 400; 

    sdspi_slot_config_t slot_config = SDSPI_SLOT_CONFIG_DEFAULT();
    slot_config.gpio_miso = PIN_NUM_MISO;
    slot_config.gpio_mosi = PIN_NUM_MOSI;
    slot_config.gpio_sck  = PIN_NUM_CLK;
    slot_config.gpio_cs   = PIN_NUM_CS;
    slot_config.gpio_cd   = SDMMC_SLOT_NO_CD;
    slot_config.gpio_wp   = SDMMC_SLOT_NO_WP; 

    esp_vfs_fat_sdmmc_mount_config_t mount_config = {
        .format_if_mount_failed = true,
        .max_files = 5
    };

  
    sdmmc_card_t* card;
    esp_err_t ret = esp_vfs_fat_sdmmc_mount("/sdcard", &host, &slot_config, &mount_config, &card);

    if (ret != ESP_OK) {
        if (ret == ESP_FAIL) {
            ESP_LOGE(TAG, "Failed to mount filesystem. "
                "If you want the card to be formatted, set format_if_mount_failed = true.");
        } else {
            ESP_LOGE(TAG, "Failed to initialize the card (%d). "
                "Make sure SD card lines have pull-up resistors in place.", ret);
        }
        return;
    }

    // Card has been initialized, print its properties
    sdmmc_card_print_info(stdout, card);

    // Use POSIX and C standard library functions to work with files.
    // First create a file.
   #define PATH1   "/sdcard/hello.txt"

 ESP_LOGI(TAG, "Opening file");
    f = fopen(PATH1, "w");
    if (f == NULL) {
        ESP_LOGE(TAG, "Failed to open file for writing");
        return;
    }else
	ESP_LOGI(TAG, "Success to open file for writing");
    ret = fprintf(f, "Hello %s!\n", card->cid.name);   
    ESP_LOGI(TAG, "closing..");
    fclose((FILE*)f);
     ESP_LOGI(TAG, "closed");
    esp_vfs_fat_sdmmc_unmount();
    ESP_LOGI(TAG, "Card unmounted");
