Error uploading to Arduino MKR1000

[mfusco]

I'm trying to upload the sketch below and I'm getting an error. I tried uploading a blink sketch and that works, but not the following code:

  basically do whatever you want with this code.

  This example reads the tag device ID and revision number over I2C and outputs
  them to the serial port

  Hardware Connections:
  Plug a Qwiic cable into the Qwiic RFID Tag and a RedBoard
  If you don't have a platform with a Qwiic connection use the SparkFun Qwiic Breadboard Jumper (https://www.sparkfun.com/products/14425)

#include <SparkFun_ST25DV64KC_Arduino_Library.h> // Click here to get the library:  http://librarymanager/All#SparkFun_ST25DV64KC

SFE_ST25DV64KC tag;

void setup()
{
  delay(1000);

  Serial.begin(115200);
  Wire.begin();

  Serial.println(F("ST25DV64KC example."));

  if (!tag.begin(Wire))
  {
    Serial.println(F("ST25 not detected. Freezing..."));
    while (1) // Do nothing more
      ;
  }

  Serial.println(F("ST25 connected."));

  uint8_t values[8] = {0};
  if (tag.getDeviceUID(values))
  {
    Serial.print(F("Device UID: "));
    for (uint8_t i = 0; i < 8; I++)
    {
      if (values[i] < 0x0a)
        Serial.print(F("0"));
      Serial.print(values[i], HEX);
      Serial.print(F(" "));
    }
    Serial.println();
  }
  else
    Serial.println(F("Could not read device UID!"));
  
  uint8_t rev;
  if (tag.getDeviceRevision(&rev))
  {
    Serial.print(F("Revision: "));
    Serial.println(rev);
  }
  else
    Serial.println(F("Could not read device revision!"));
}

void loop()
{
  // Nothing to do here
}

The upload takes a long time. About halfway through, I get this error:

No upload port found, using /dev/cu.usbmodem11101 as fallback

And eventually, I get this error:

Timeout. The IDE has not received the 'success' message from the monitor after successfully connecting to it. Could not connect to /dev/cu.usbmodem11101 serial port.

I will note that I have a sensor with the following connections:

SCL to SCL
SDA to SDA
Vcc to 3.3v
GND to GND

Any help would be greatly appreciated. Thank you.

did you try a different cable?

[mfusco]

Yes, with the same result.

Update: Now, even a blink sketch won't upload.

[Juraj]

use double reset to activate the bootloader. the L LED should pulsate

[mfusco]

I'm still getting the same error. The blink sketch uploaded successfully after double resetting the board, but not the sketch in the OP.
