Can't Upload to Arduino Uno

I just installed PIO, and I’d like to upload a sketch to my Arduino Uno, I’m able to build the sketch no problemo, but uploading fails consistently, and I can’t figure out how to get it working.

I’m running PIO on Windows 8.1. I have my Uno connected to my PC via a USB cable on COM6. My Arduino driver is up to date. I’m able to upload the same sketch on this computer to my Uno using the Arduino IDE.

Whenever I try to upload my sketch, PIO reports:

It looks to me like the baud rate is increased from 9600 to 115200. I don’t know how to prevent this override condition?

Thanks, in advance for your help :wink:

Hi @engGuy

Sorry, but I couldn’t reproduce your issue, my Uno works fine.
Could you please test this avrdude? Just replace the old version in:

Thanks @valeros! The avrdude you gave me works. What magic did you do?
