# ChibiOS Upgrade Procedure
|
||
|
|
|
||
|
|
ChibiOS and ChibiOS-Contrib need to be updated in tandem -- the latter has a branch tied to the ChibiOS version in use and should not be mixed with different versions.
|
||
|
|
|
||
|
|
## Getting ChibiOS
|
||
|
|
|
||
|
|
* `svn` Initialisation:
|
||
|
|
* Only needed to be done once
|
||
|
|
* You might need to separately install `git-svn` package in your OS's package manager
|
||
|
|
* `git svn init --stdlayout --prefix='svn/' http://svn.osdn.net/svnroot/chibios/`
|
||
|
|
* `git remote add qmk git@github.com:qmk/ChibiOS.git`
|
||
|
|
* Updating:
|
||
|
|
* `git svn fetch`
|
||
|
|
* First time around this will take several hours
|
||
|
|
* Subsequent updates will be incremental only
|
||
|
|
* Tagging example (work out which version first!):
|
||
|
|
* `git tag -a ver20.3.3 -m ver20.3.3 svn/tags/ver20.3.3`
|
||
|
|
* `git push qmk ver20.3.3`
|
||
|
|
* `git tag -a breaking_YYYY_qN -m breaking_YYYY_qN svn/tags/ver20.3.3`
|
||
|
|
* `git push qmk breaking_YYYY_qN`
|
||
|
|
|
||
|
|
## Getting ChibiOS-Contrib
|
||
|
|
|
||
|
|
* `git` Initialisation:
|
||
|
|
* `git clone git@github.com:qmk/ChibiOS-Contrib`
|
||
|
|
* `git remote add upstream https://github.com/ChibiOS/ChibiOS-Contrib`
|
||
|
|
* `git checkout -b chibios-20.3.x upstream/chibios-20.3.x`
|
||
|
|
* Updating:
|
||
|
|
* `git fetch --all --tags --prune`
|
||
|
|
* `git checkout chibios-20.3.x`
|
||
|
|
* `git pull --ff-only`
|
||
|
|
* `git push origin chibios-20.3.x`
|
||
|
|
* `git tag -a breaking_YYYY_qN -m breaking_YYYY_qN chibios-20.3.x`
|
||
|
|
* `git push origin breaking_YYYY_qN`
|
||
|
|
|
||
|
|
## Updating submodules
|
||
|
|
|
||
|
|
* Update the submodules
|
||
|
|
* `cd $QMK_FIRMWARE`
|
||
|
|
* `git checkout develop`
|
||
|
|
* `git pull --ff-only`
|
||
|
|
* `git checkout -b chibios-version-bump`
|
||
|
|
* `cd lib/chibios`
|
||
|
|
* `git fetch --all --tags --prune`
|
||
|
|
* `git checkout breaking_YYYY_qN`
|
||
|
|
* `cd ../chibios-contrib`
|
||
|
|
* `git fetch --all --tags --prune`
|
||
|
|
* `git checkout breaking_YYYY_qN`
|
||
|
|
* Build everything
|
||
|
|
* `cd $QMK_FIRMWARE`
|
||
|
|
* `qmk multibuild -j4`
|
||
|
|
* Make sure there are no errors
|
||
|
|
* Push to the repo
|
||
|
|
* `git commit -am 'Update ChibiOS to XXXXXXXXX'`
|
||
|
|
* `git push --set-upstream origin chibios-version-bump`
|
||
|
|
* Make a PR to qmk_firmware with the new branch
