Hi @DesignToHelp

Please check below.

Is the openCR power on?
Is the openCR connected to pc?
Do you select the right comport on Arduino IDE?

You can get help on below page.

The answer to all of those is YES. I was able to solve the issue by Holding down SW2 button, pressing RESET button, releasing RESET button and then releasing SW2 button.

Then windows started recognizing the board. But, why did it happen in the first place?

Hi @DesignToHelp

I'm sorry for the late reply.

There was a problem with your openCR upload.

And I'm not sure what kind of problem was because the information of error is not enough.

What you did is recovery mode and you can check on below.
