WSL2 環境で MicroPython の Build
ここでは、Windows PC で、STM32系の市販されているボードに MicroPython を実装する手順を記録します
WSL2 (Ubuntu) のインストール
STM32系のARM用のコンパイルには、この環境が最適のようです この記事がていねい
- Windows11 の右クリックで[ターミナル(管理者)]を起動
PS C:\Users\user> wsl --install
- 以下は、インストールが終わって、再起動した直後
Ubuntu は既にインストールされています。 Ubuntu を起動しています... Installing, this may take a few minutes... Please create a default UNIX user account. The username does not need to match your Windows username.

To run a command as administrator (user "root"), use "sudo <command>". See "man sudo_root" for details.
