Hello!

I own one of the original Redboards as sold via MicroCenter for Sparkfun. On this laptop who runs Windows 11 I am now getting output which looks like this:

avrdude done. Thank you.

Failed uploading: uploading error: exit status 1

Anyway that happens on both 2.3.6 and 2.3.7.

1- Are you sure the board is actually on com4?
2- Does it work on another computer?

It is indeed on COM4. However I’m away at the moment, and do not have another one to try it out on. However the code that I was trying to make work, did work on an older version.
