Arduino IDE port selection unavailable

Post by PhilippCaspari »

Hey there,

I just bought a new Adafruit feather nRF52480 express and wanted to get going with the tutorials and examples provided by this page:
https://learn.adafruit.com/introducing- ... 0-feather/
I was able to connect and everything worked, until I uploaded the example code from the following site:
https://learn.adafruit.com/introducing- ... oard-setup
-under the heading "4. Run a sketch" the following sketch can be found:
void setup() {
pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}

I uploaded the sketch and now the IDE can not find the board anymore with: tools -> port
I is clearly a software problem, because everything worked before I uploaded this example sketch, because nothing else in the setup has changed.

For everyone who has the same problem, the solution is to update the bootloader externally via a windows command shell. A written guide to update the bootloader "manually" is here:

However, there is a much better video guide on Youtube:
