Using HSPI pins on ESP32 for interfacing SD card module

[PrateekGoyal18]

Hello everyone, I am trying to interface SD card module on the HSPI pis of ESP32 since I need to use to VSPI pins as GPIO for some other task. My code is,

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

SPIClass spiSD(HSPI);
#define SD_CS 15

void setup()
{
  Serial.begin(9600);
  Serial.println();
  SPI.end(); 
  spiSD.begin(14, 12, 13, SD_CS); //CLK,MISO,MOIS,SS
  if (!SD.begin(SD_CS, spiSD))
  {
    Serial.println("Card Mount Failed");
    return;
  }
  else
  {
    Serial.println("Card Mount Successful");
  }
}

void loop()
{ }

First of all if I upload the code with all the pins of sd card module connected to esp32, it does not upload due to I think GPIO12 property "boot fail if pulled high". So when I take out the jumper form GPIO12 and upload the code, some errors are thrown on the Serial monitor. Can anyone help me out here?

You are too far away for my mind reading to work. Please turn on verbose logging, and post the log. Please read the issue template, and provide the information requested there, along with your device connection information- particularly what sort of pullup resistors you are using. For GPIO12, see https://github.com/espressif/esp-idf/tree/master/examples/storage/sd_card#note-about-gpio12

Finally, it would be possible use HSPI for smartmatrix-teensylc ESP32 compatible library, with this pins arrangement in MatrixHardware_ESP32_V0.h smartmatrix file,

**#define R1_PIN  GPIO_NUM_2
#define G1_PIN  GPIO_NUM_23//15
#define B1_PIN  GPIO_NUM_4
#define R2_PIN  GPIO_NUM_16
#define G2_PIN  GPIO_NUM_27
#define B2_PIN  GPIO_NUM_17

#define A_PIN   GPIO_NUM_5
#define B_PIN   GPIO_NUM_18
#define C_PIN   GPIO_NUM_19
#define D_PIN   GPIO_NUM_21
#define E_PIN   GPIO_NUM_33//12
#define LAT_PIN GPIO_NUM_26
#define OE_PIN  GPIO_NUM_25**

And this in the smartmatrix_player.ino

SPIClass spiSD(HSPI);

// Chip select for SD card

if defined(ESP32)

#define SD_CS 15     // 5 **

elif defined (ARDUINO)

#define SD_CS BUILTIN_SDCARD
//#define SD_CS 15

endif

....................... ....................... .......................

Serial.print("Initializing SD card...");

spiSD.begin(14, 32, 13, 15); //SCK,MISO,MOSI,SS //HSPI1

if (!SD.begin( SD_CS, spiSD )) { Serial.println("Card Mount Failed"); return; }

Then, it run perfectly, loading gifs from /gifs directory

Hi I am facing something similar issue where with latest ESP32 Board manager my ICM-20948 is not working on HSPI as it was working earlier nicely with 1.0.6 version. where do I find the file you mentioned? MatrixHardware_ESP32_V0.h?
