Configuration¶
You can configure debugging tool using debug_tool option in “platformio.ini” (Project Configuration File):
[env:myenv]
platform = ...
board = ...
debug_tool = gd-link
If you would like to use this tool for firmware uploading, please change upload protocol:
[env:myenv]
platform = ...
board = ...
debug_tool = gd-link
upload_protocol = gd-link
