This not a blink.
try, and check serial console:
void loop() {
Serial.print(".");
digitalWrite(ONBOARD_LED,HIGH);
delay (1000);
digitalWrite(ONBOARD_LED,LOW);
delay (1000);

Re: ESP32 SD card info

The pinout change in your source:
SPI.begin( 14, 2, 15, 13); // The bultin SD card SPI for WROVER
void begin (int8_t sck=-1, int8_t miso=-1, int8_t mosi=-1, int8_t ss=-1);// this SPI.begin defined in spi.h
