Sketch

The included example SdInfo. I got the same results from BufferedPrint.

What happened ?

When running the example there is no Serial output at all. This on a Nano ESP32 which has been writing Serial output every day, still connected the same way.

The problem does not appear to be SD related.

How to reproduce ?

1. Go to File -> Examples -> SdFat - Adafruit Fork -> SdInfo
2. Click the arrow to install and upload.
3. Check the Serial Monitor
4. Nothing there

This does not seem to be SD related. I added a single Serial.println before any SD-related coded and it still does nothing:

void setup() {
  Serial.begin(9600);
  // Wait for USB Serial
  while (!Serial) {
    yield();
  }
  Serial.println("Anything?");  // NEW LINE
  cout << F("SdFat version: ") << SD_FAT_VERSION_STR << endl;
  printConfig(SD_CONFIG);

}

A workaround is simple enough. Change setup() to this and the example works perfectly:

void setup() {
  Serial.begin(9600);
  // Wait for USB Serial
  delay(5000);  // Fixed delay instead of a while()
  cout << F("SdFat version: ") << SD_FAT_VERSION_STR << endl;
  printConfig(SD_CONFIG);
}

This may not be the best code to put into the repository, but it works!
