PC doesn't recognize Itsy Bitsy

by topper2k on Fri Apr 16, 2021 11:30 pm

I’ve got a project (an arcade lightgun) built with a ItsyBitsy 32U4 5v 16mhz board. To initially install my project, I followed all the steps to add the board and get it setup with the IDE. (https://learn.adafruit.com/introducting ... -ide-setup).

The project has been working fine for a couple weeks. Today I plugged it in to upload a code update and I can’t seem to connect to the board.

I get the normal beep boop when I plug the USB cable in. But I don’t see the device in Device Manager.

In the Arduino IDE, I can see I have the correct board selected, but the com port selection is grayed out.

Looking at the board I’ve got a single red blinking LED.

Here's what I've already tried:

Rebooted the PC
Uninstalled and reinstalled Arduino IDE
Reinstalled board list
Manually installed Adafruit device drivers

Any idea what could be wrong?

I've tried this on three different PCs now with the same results. Two of the PCs had previously been used to upload sketches to this ItsyBitsy board. The third was a fresh install of the Arduino IDE, etc. I'm stumped.

I think I've solved this.

I activated the bootloader by double tapping the reset button. Then I initiated an upload of the "bare minimum" example sketch. And double tapped the reset button again.

This successfully uploaded the minimum sketch. I was then able to upload other sketches as well.
