Pull request overview
This PR adds a new debugApp helper script to the ledgerblue tool suite to listen to Ledger app PRINTF output exposed via USB CDC when the app is built with DEBUG_OVER_USB, and wires it into the documentation and packaging dependencies.
Changes:
- Add
ledgerblue/debugApp.pyCLI script to auto-detect a Ledger CDC serial port and stream debug output to stdout (optionally to a file). - Add
pyserialas a project dependency to support USB CDC serial access. - Document the new script in the Sphinx script reference.
