I'm stuck. Unable to flash the Arduino Pro Micro as microUPDI programmer

Hello,

I have a working Pro Micro. Uploaded the Pro Micro Test Code and I get blinking LEDs.

When I select microUPDI Firmware Uploader from the boards menu and click the upload button I get an error.

What path can't be found? What am I missing?

So I still don't know why I get the error. But I managed to upload the firmware using a modified version of scripts\CLI flash script\Load_firmware.bat and a Arduino UNO as Arduino ISP. It looks like a got a working microUPDI programmer as I managed to upload firmware to an ATMega4809.

Hi! Sorry for the late reply! Great to hear you managed to upload the firmware through the alternative script provided. I'll try to look into why you weren't able to upload the firmware using the IDE.
