Zephyr SDK with Crosstool NG

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 and Mac in a consistent way, apply patches where needed.

Currently we build the following toolchains:

• i586
• iamcu
• nios2
• arm
• riscv32
• mips
• xtensa

To build for any of the above, run:

./go.sh <arch>

PR Builds

Successfull PR builds will get posted here:

Release Process

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.
