This project is to replace the current Yocto based SDK with a new framework for building the Zephyr SDK using crosstool-ng.

The repoistory consists of configurations for the various architectures (not fully tests) and a script that builds on Linux (x86_64) and Mac in a consistent way, apply patches where needed.

Currently we build the following toolchains:

• i586
• nios2
• arm
• arm64
• riscv64
• sparc
• xtensa (sample_controller, intel_apl_adsp, intel_s1000)

To build for any of the above, run:

./go.sh <arch>

Pre-built binaries releases of the SDK are made and currently only available for an x86_64 Linux host environment. The releases 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//zephyr-sdk--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.
• One the release is created, CI will build the SDK image and will upload it to the release page.
