I am having trouble getting the SD library examples working on a ESP32-EVB board.
The example compiles but I see "Card Mount Failed" in the terminal.
I am not sure if the SD pinouts are correct, but I would not be able to change them as this is a single PCB:
As stated in the arduino-esp32 SD_MMC example it says to use the following pins:
/* Connect the SD card to the following pins: * * SD Card | ESP32 * D2 12 * D3 13 * CMD 15 * VSS GND * VDD 3.3V * CLK 14 * VSS GND * D0 2 (add 1K pull up after flashing) * D1 4 */
Is this board compatible with the SD_MMC library (the schematic is not clear to me)?
I am using a Sandisk Ultra PLUS 16g. I formatted it to 256Mb (both fat16 and fat32).
What else should I try?
