ESP32 SD Mount Failed
Posted: Mon Jan 02, 2023 11:31 am
Hey there! Recently, I ran into a problem with sd mounting. It always says "SD mount failed", even when SD is not inserted. SD module is wired to standard VSPI pins.
here's a sketch:
And here's a serial response:
Maybe someone can help? Thank you!
here's a sketch:

void initTFT(){
TFT_eSPI tft=TFT_eSPI();
tft.init();
tft.fillScreen(TFT_BLACK);
tft.drawString("Hello World! I'm OstapStad", 2, 2);
}
void initSDCard(){
if(!SD.begin()){
Serial.println("Card Mount Failed");
return;
}
uint8_t cardType = SD.cardType();
if(cardType == CARD_NONE){
Serial.println("No SD card attached");
return;
}
Serial.print("SD Card Type: ");
if(cardType == CARD_MMC){
Serial.println("MMC");
} else if(cardType == CARD_SD){
Serial.println("SDSC");
} else if(cardType == CARD_SDHC){
Serial.println("SDHC");
} else {
Serial.println("UNKNOWN");
}
uint64_t cardSize = SD.cardSize() / (1024 * 1024);
Serial.printf("SD Card Size: %lluMB\n", cardSize);

void setup() {
// put your setup code here, to run once:
