Card mount failed

[YannSchaum]

Hi, I am trying to save some GPS data on a sd card using the slot on the board but it always fails to mount. I succeeded with an external sd card module with the same card which is Fat32 SDHC 4GB. I also carefully changed the SPI pins. Here is my script : /*

• Connect the SD card to the following pins:
• SD Card | ESP32
• D2 -
• D3 SS
• CMD MOSI
• VSS GND
• VDD 3.3V
• CLK SCK
• VSS GND
• D0 MISO
• D1 - */

define SD_MISO 2

define SD_MOSI 15

define SD_SCLK 14

define SD_CS 13

define LED_PIN 12

    return;

u have a solution?

[PhilC66]

High, Same problem, solved with inserting those lines before SPI.begin pinMode (SD_SCLK, INPUT_PULLUP); pinMode (SD_MISO, INPUT_PULLUP); pinMode (SD_MOSI, INPUT_PULLUP); pinMode (SD_CS, INPUT_PULLUP);

hope this help
