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 ver20.3.4 -m ver20.3.4 svn/tags/ver20.3.4
    • git push qmk ver20.3.4
    • git tag -a develop_YYYY_qN -m develop_YYYY_qN svn/tags/ver20.3.4
    • git push qmk develop_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 develop_YYYY_qN -m develop_YYYY_qN chibios-20.3.x
    • git push origin develop_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 develop_YYYY_qN
    • cd ../chibios-contrib
    • git fetch --all --tags --prune
    • git checkout develop_YYYY_qN
  • Update ChibiOS configs within QMK
    • cd $QMK_FIRMWARE
    • ./util/chibios_conf_updater.sh
  • Build everything
    • cd $QMK_FIRMWARE
    • qmk multibuild -j4
    • Make sure there are no errors
  • Push to the repo
    • git commit -am 'Update ChibiOS to 99.9.9'
    • git push --set-upstream origin chibios-version-bump
  • Make a PR to qmk_firmware with the new branch
