| Setting Environment Variables |
| ============================= |
| |
| Set environment variables every time you open a terminal console to work on |
| applications. |
| |
| Steps |
| ----- |
| |
| 1. In a shell terminal console, enter an :command:`export` command that is |
| consistent with your toolchain. |
| |
| For the Zephyr SDK: |
| |
| .. code-block:: console |
| |
| $ export ZEPHYR_GCC_VARIANT=zephyr |
| $ export ZEPHYR_SDK_INSTALL_DIR=<yocto-installation-path> |
| |
| 2. To set the environment variable :envvar:`\$ZEPHYR_BASE`, navigate to the |
| kernel's installation directory and enter: |
| |
| .. code-block:: console |
| |
| $ source zephyr-env.sh |
