east-tool 0.20.0

Tool built on top of West for managing nRF Connect SDK projects.

East - tool for building NCS/Zephyr applications

East is a command line meta-tool, useful for creating, managing, and deploying Zephyr or nRF Connect SDK (NCS) projects.

It is built on top of Zephyr's RTOS meta-tool West and Nordic's nRF Connect Toolchain Manager.

Reasoning behind East

There are several reasons why someone would like to create yet another tool on top of west:

• Working on several projects at once means using different versions of the NCS repository and different versions of the toolchain. Managing these differences is not a trivial task.
• There is no reproducible build guarantee between the developer's machines. Slight differences between tool versions can manifest into hard-to-find bugs.
• Creating GitHub releases manually takes ages as you have to run the build process for every combination of the board, application, build variant, etc. and properly rename the release binary. The release procedure gets longer with every addition of new hardware and build variation option.

East automates the above tasks and tries to make the developer more productive.

Key features

• Automated detection and installation of tooling required for NCS projects.
• Common west commands used for the development, such as build, flash, etc.
• Sandboxed development environment, thanks to the nRF Connect Toolchain Manager, every build, flash, etc. command runs inside of its toolchain environment.
• Automated process of generating release artefacts for your entire project, no matter the number of applications, samples or boards.
• Support for build types, which is integrated into the usual build process.
• RTT utility commands to connect and see the RTT stream.
