This project is to replace the previous Yocto based SDK with a new framework for building the Zephyr SDK using crosstool-ng. (Some tools are still built using Yocto/Bitbake).
The repository consists of configurations for the various architectures (not all fully tested) and a script that builds on Linux (x86_64) and Mac in a consistent way, applying patches where needed.
Currently we build the following toolchains:
- i586
- nios2
- arc
- arc64
- arm
- arm64
- riscv64
- sparc
- mips
- xtensa (sample_controller, intel_apl_adsp, intel_s1000, intel_bdw_adsp, intel_byt_adsp, nxp_imx_adsp, nxp_imx8m_adsp)
To build for any of the above, run:
./go.sh <arch>
Production builds are done using the scripts in .buildkite/ and
.github/workflows/ which identify some packages you'll need to
have installed for the above command to work.
When building locally be aware that ./go.sh is written assuming it's
invoked in a pristine workspace. That means if you pull an update of
this repository ./go.sh will not update the crosstool-ng source or
rebuild the bin/ct-ng utility to match the updated configuration. This
can produce very confusing results.
Pre-built binary releases of the SDK are made for a few OSes and host architectures. They can be found here:
https://github.com/zephyrproject-rtos/sdk-ng/releases
Successfull PR builds will get posted here:
https://builds.zephyrproject.org/zephyrproject-rtos/sdk-ng/<PR_NUMBER>/zephyr-sdk-<VERSION>-setup.run
To release a new SDK:
- Update the VERSION file with the new version, for example 0.11.0 or 0.11.0-beta1 etc.
- On https://github.com/zephyrproject-rtos/sdk-ng/releases, create the release tag and add the release information.
- Once the release is created, CI will build the SDK image and will upload it to the release page.
