Hello,
I would like to ask you for your help. I’m compiling my first code under PlatformIO, it’s a simple listing of available wifi networks. I get an error when I compile that I can’t resolve:

Thank you very much for your help

  1. Does it work without all extra_scripts?
  2. Can you do a clean reinstall of platform + framework + toolchain code to make sure all-latest versions are installed? I’d just recommend deletion of C:\Users\<user>\.platformio and restarting VSCode.

You have the wrong board in your platformio.ini. It should be:

[env:rpipicow]
board = rpipicow
