stm32: Factory reset from code

I believe factory reset should be available as an alternative to USR. USR might not be practical or accessible for custom boards or how the device might be enclosed or accessed.

This might also be related to ways to clear/format/erase the filesystem from code.

Basically recovery and housecleaning.

stm32: Move factory reset files and code to separate source file.

closedby dpgeorgeopened 2019-05-06updated 2019-05-07

The new function factory_reset_make_files() populates the given filesystem with the default factory files. It is defined with weak linkage so it can be overridden by a board.

This commit also brings some minor user-facing changes:

boot.py is now no longer created unconditionally if it doesn't exist, it is now only created when the filesystem is formatted and the other files are populated (so, before, if the user deleted boot.py it would be recreated at next boot; now it won't be).
pybcdc.inf and README.txt are only created if the board has USB, because they only really make sense if the filesystem is exposed via USB.

Assessment

Q Qwen · high

The query (Issue #4832) requests a feature to implement factory reset functionality accessible from code as an alternative to the USR button, including filesystem clearing/formatting. The candidate (PR #4752) is a refactoring PR that moves existing factory reset file creation logic into a separate source file with weak linkage for board customization. While PR #4752 deals with factory reset code organization and file provisioning, it does not implement the core feature requested in the issue: making factory reset callable from Python code or providing a programmatic way to trigger a factory reset. The PR improves the infrastructure for factory reset but doesn't address the accessibility from code aspect that is the main request.

Suggested action

Keep both items open. The PR improves factory reset code organization but does not resolve the feature request. The issue should remain open to track the implementation of programmatic factory reset functionality.
