      Trying to connect SD Card Module via External SPI. Keep getting Card Mount Failed. Tried with both 3.3 and 5v external power. Can someone please tell me what I'm doing wrong?

      #include <M5StickCPlus.h>
      #include "SD.h"
      SPIClass SPI_EXT;
      // PIN配置
      enum { spi_sck = 0, spi_miso = 36, spi_mosi = 26, spi_ss = -1 };
      void setup()
      {
      // M5StickC initialize
      M5.begin();
      M5.Lcd.setRotation(3);
      // SPI initialize
      SPI_EXT.begin(spi_sck, spi_miso, spi_mosi, spi_ss);
      // SD initialize
      if (!SD.begin(spi_ss, SPI_EXT)) {
      M5.Lcd.println("Card Mount Failed");
      return;
      }
      // SD check
      uint8_t cardType = SD.cardType();
      if (cardType == CARD_NONE) {
      M5.Lcd.println("None SD Card");
      return;
      }
      M5.Lcd.print("SD Card Type: ");
      if (cardType == CARD_MMC) {
      M5.Lcd.println("MMC");
      } else if (cardType == CARD_SD) {
      M5.Lcd.println("SDSC");
      } else if (cardType == CARD_SDHC) {
      M5.Lcd.println("SDHC");
      } else {
      M5.Lcd.println("UNKNOWN");
      }
      // SD volume
      uint64_t cardSize = SD.cardSize() / (1024 * 1024);
      M5.Lcd.printf("SD Card Size: %lluMB\n", cardSize);
      }
      void loop() {
      }
