You’ll prepare a Zephyr workspace, install the Zephyr SDK, and build samples for a Cortex-M-based Corstone-300 target. First, you’ll obtain the Zephyr source and configure your development environment. Then, you’ll build the application and run its binary on the Corstone-300 Fixed Virtual Platform (FVP) through Arm Virtual Hardware, locally or in the cloud.

Can I complete the Learning Path without physical hardware?
Yes. You build Zephyr sample applications and run them on the Arm Corstone-300 FVP provided by Arm Virtual Hardware.
Which environment should I use to run the simulator?
Use a Linux machine or Linux-based Arm Virtual Hardware.
How do I know the Zephyr build worked?
The build completes without errors and generates the application artifacts for the Corstone-300 target. Proceed when the build finishes cleanly.
What console output should I expect from the Corstone-300 FVP?
The FVP opens telnet terminal windows that show a Zephyr boot message followed by Hello World! mps3_an547.
Where can I find the built Zephyr application?
You’ll find the application binaries in ~/zephyrproject/zephyr/build/zephyr/. Use the zephyr.elf file from this directory when you run the application on the Corstone-300 FVP.
