I recently started playing with Arduino Nano 33 BLE, and for some reason I cannot any more upload any new sketch on the device. When I connect the Arduino and open the serial monitor I do see the output of the last sketch I managed to upload, but when I try uploading a new, it says “Uploading…” for a very long time and then displays:
No device found on cu.usbmodem14201 An error occurred while uploading the sketch
I am using Mac OS X on my MacBook Pro laptop, but I have tried with a different computer running Windows and the problem remains the same.
Could have I done something bad with the last uploaded sketch so that the device is now stuck? Is there any way to reset the device?
Thanks in advance for your help.
