How do I know I installed the Workbench for Zephyr extension correctly?
The setup is correct if the extension completes SDK and toolchain configuration and you can create and build a Zephyr application without errors. A memory usage report generated after the build is another good confirmation.
Which board should I select when creating the project?
Choose your Zephyr-supported Arm Cortex-M board. NXP FRDM-MCXN947 is used as an example, and you can confirm other options in the Zephyr Supported Boards list .
Where do I configure a debug runner that Workbench for Zephyr doesn't detect?
Open the Debug Manager from the sidebar, locate your board profile, and enter the full path to the runner executable.
What result should I expect after a successful build?
Expect build artifacts for your application and a generated memory usage report from Workbench for Zephyr. These outputs indicate the project is ready for debugging on the selected board.
How do I open the memory reports after a successful build?
In the Workbench for Zephyr panel, select Memory Analysis. You can then review RAM usage, ROM usage, and Puncover analysis.
