 well my board is an ESP32 cam module with microSD card socket. The esp32s can't mount the card. I installed the board file esp32 by Espressif Systems according to these instructions.
i loaded a webserver sketch and it worked. but i've tried many sketches for microSD interface and gotten nowhere.
i simplified the code down to this:
Code: [Select]
#include "SD.h"

void setup() {
  if(!SD.begin()) Serial.println("Card Mount Failed");
  else Serial.println("success");

void loop() {}

then i got a meter and verified the connections according to this image. still the SD.begin command returns 0. can't figure out why.


Same problem here. SD slot not working at all. The card never gets mounted.
