Driver Install Error - SparkFun Qwiic Pro Micro - USB-C (ATmega32U4)

Development Boards Arduino

I loaded up the Blinkies example from the following URL and after loading that to the board I have been unable to re-connect the board.

I tried following the example section for re-installing the driver but I get the below error.

Any help would be appreciated.

I have tried using both the Arduino IDE and the CLI however I can not get the sketch to upload to the board. The CLI seems faster/easier but the Pro Micro only lasts ~8 seconds in the bootloader mode before it leaves which is just not enough time.

Ah. What I found is that when you run the below, if you run the script first and then wait for the upload line to appear you can double press the reset button right when that shows up and then there is no “timing it” since the script is waiting for the board. :sunglasses:
