Raspberry Pi Pico を VSCodeでデバッグ

2023-07-06 組み込み

何をするのか

Raspberry Pi Pico を C/C++ でソースコードデバッグしたい。そのために、Seeed XIAO RP2040をPicoProbeにしてVS Code に設定を施す。

Seeed XIAO RP2040
https://www.seeedstudio.com/XIAO-RP2040-v1-0-p-5026.html

設定とかの参考
https://learnembeddedsystems.co.uk/133-2

はまりどころ

  • セットアップファイルは https://github.com/ndabas/pico-setup-windows にあった
  • Download the latest release をクリックして pico-setup-windows-0.3.4-x64.exe をダウンロード＆インストール。
  • openOCD のビルド　で MSYSやら 様々インストールを求められる
    →　MSYSやopenOCDをダウンロードしたのにビルドが通らない？
    →　あらかじめビルド済バイナリがあった
    https://learnembeddedsystems.co.uk/133-2 の “Prebuilt OpenOCD for windows and PicoProbe” にある zip ファイル
  • 設定ファイルに記述が必要。
    C:\pico\pico-examples.vscode の lauch.json と settings.json が対象。
