ChibiOS has moved from SVN to Git

ChibiOS has moved from SVN to Git

After many years on SourceForge Subversion, ChibiOS development has migrated to Git, hosted on GitHub. This is now the authoritative home for the source.

New repositories (under the chibios-upstream organization):

• chibios — the OS itself: RT, NIL, HAL, SB, the test suites, demos and docs
• chibios-tools — ChibiStudio tooling
• chibios-ext — third-party libraries (FatFS, lwIP, littlefs, wolfSSL) as archives
• chibios-ftl — FreeMarker code-generation templates

Getting the code

The ext/ and tools/ftl directories are Git submodules, so clone recursively:

Code: Select all

git clone --recurse-submodules https://github.com/chibios-upstream/chibios.git
git clone --recurse-submodules https://github.com/chibios-upstream/chibios-tools.git

If you already cloned without submodules, run:

Code: Select all

git submodule update --init --recursive

SSH works too — the submodule URLs are relative, so they follow whatever protocol you cloned with.

For existing SVN users — what maps to what

• trunk becomes the branch main
• branches/stable_XX.Y.x become the branches stable-19.1.x, stable-20.3.x, stable-21.11.x
• tags/verXX.Y.Z become the tags ver_XX.Y.Z (tag names were normalized to a consistent ver_ prefix)

If you used to keep several branches in separate checkouts, Git worktrees reproduce that layout from a single clone:

Code: Select all

git clone --recurse-submodules https://github.com/chibios-upstream/chibios.git chibios
cd chibios
git worktree add ../chibios-stable-21.11.x stable-21.11.x

About history

The Git repository carries a release-snapshot history: one commit per release, with all release tags preserved and their original dates. The full revision-by-revision SVN history is not reproduced in Git; it remains available in the SourceForge SVN repository, which stays online as a permanent, read-only archive:

Code: Select all

https://svn.code.sf.net/p/chibios/code

The SVN repository is being frozen to read-only, so please do not rely on it for new commits.

Issues and tickets

Bug tracking moves to GitHub Issues on the chibios repository. We are importing the active (open and recent) SourceForge tickets; older and closed tickets remain in the SourceForge archive.

Contributing

Contributions are now made via fork and pull request on GitHub. Please remember to use --recurse-submodules when cloning your fork. The license is unchanged (GPL3 plus commercial, as before).

Thanks for bearing with the move. Git brings easier contribution, proper branching, and a smoother workflow for everyone.
