Vex Pros not properly uploading

Programming Support
#1

Hi, I have been trying to figure this out for over a week, I have

  • Read every related forum post and all the relevant PROS documentation
  • Reinstated pros multiple times (The VS Code extension in the downloadable one)
  • Made sure all the firmware and software were updated on the brain and controller
  • Did multiple clean installations of VS Code and its extensions
  • Factory reset the brain and controller
  • Added PROS to path
  • And much more
    I still can’t seem to fix it, so I am making my first post to the forums as a last-ditch plea for help.

Here is the PowerShell output with an explanation below.

So originally I was getting the error above whenever I tried to upload my PROS project. So I followed the directions in this post Pros 3.4.0 - #9 by Floppy108F and then factory reset and wiped all the programs from the brain and got this new error that I am stuck on.

C:\Users\****\OneDrive\Documents\GitHub\Robotics-team-coding-repo\Pros\test-3> prosv5 mu

If anyone could respond to a possible solution I would be incredibly grateful, thanks.

You… didn’t post your code?

The project is just a newly created pros project. Right off the bat. No modification. I just created the project (for testing purposes which is why I named it test-3) and then tried uploading it. If you are so desperate here is the GitHub repo with the pros projects in it.

If the V5 brain firmware fully up to date ? (vexos 1.1.1)
