SD card fail to mount

[davidkleng]

Hardware:

Board: ESP32-WROOM-32U Core Installation version: platformio/framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32.git IDE name: Platform.io Flash Frequency: 40Mhz Upload Speed: 115200 Computer OS: Windows 11 ESP sdk version: v4.4-dev-3703-gddc44956bf

Description:

Im trying to initialize a SD card in SPI port.

Sketch:

platformio.ini file:

The code I wrote:

#include "FS.h"
#include "SD.h"
#include <SPI.h>

#define SD_CS 5
#define SD_SCK 18
#define SD_MISO 19
#define SD_MOSI 23

    if (!SD.begin(SD_CS))
    {
        if (serialDebug)
            Serial.println("SD CARD: INITIALIZATION FAILED");
        delay(1000);
    }
    else
    {
        SDMounted = true;
        if (serialDebug)
            Serial.println("SD CARD: Card Mount OK");
    }

also, i tried with no luck to start the spi first.

The serial output of the code is:

[  3798][W][sd_diskio.cpp:104] sdWait(): Wait Failed
[  3798][E][sd_diskio.cpp:126] sdSelectCard(): Select Failed

@P-R-O-C-H-Y PTAL, thanks!

Hi @davidkleng, when using custom pins for Sd card, you need to init the SPI first with custom pins before calling SD.begin(SD_CS);

Add this line before calling SD.begin: SPI.begin(SD_SCK, SD_MISO, SD_MOSI, SD_CS);

@P-R-O-C-H-Y , thanks for your help.

I tried that, problem persists. Also, the SD.begin() function does SPI.begin()

Hello @davidkleng, seems it could be problem with PlatformIO set up of your environment. Please take a look on this issue #6021, it can be relevant.

Try

   #define SCLK_PIN 18
   #define MISO_PIN 38
   #define MOSI_PIN 23
   #define SS_PIN 4

    SPIClass * hspi = NULL;
    hspi = new SPIClass(SPI);
    hspi->begin(SCLK_PIN, MISO_PIN, MOSI_PIN, SS_PIN);
    SD.begin(SS_PIN, *hspi *, 10000000);

or simply try

SD.begin(SS_PIN, SPI, 10000000);

[davidkleng]

It works with @bhupiister code

Try

   #define SCLK_PIN 18
   #define MISO_PIN 38
   #define MOSI_PIN 23
   #define SS_PIN 4

    SPIClass * hspi = NULL;
    hspi = new SPIClass(SPI);
    hspi->begin(SCLK_PIN, MISO_PIN, MOSI_PIN, SS_PIN);
    SD.begin(SS_PIN, *hspi *, 10000000);

or simply try

SD.begin(SS_PIN, SPI, 10000000);

Hi @davidkleng, when using custom pins for Sd card, you need to init the SPI first with custom pins before calling SD.begin(SD_CS);

Add this line before calling SD.begin: SPI.begin(SD_SCK, SD_MISO, SD_MOSI, SD_CS);

EDIT: For Future Reference:

I had the following errors using the SparkFun Thing Plus C using VS Code and PlatformIO:

[  1336][E][sd_diskio.cpp:199] sdCommand(): Card Failed! cmd: 0x00
[  1337][E][sd_diskio.cpp:802] sdcard_mount(): f_mount failed: (3) The physical drive cannot work
[  1643][E][sd_diskio.cpp:199] sdCommand(): Card Failed! cmd: 0x00
Card Mount Failed

General Code Structure:

#define SD_CS 5
#define SD_SCK 18
#define SD_MISO 19
#define SD_MOSI 2

.....

void setup()
{
     Serial.begin(115200);
     SPI.begin(SD_SCK, SD_MISO, SD_MOSI, SD_CS);

     .....
     SD.begin(SD_CS);

     .....
}

.....

Many Thanks!!
