Manage Zephyr SDK​

After importing a Zephyr SDK, it appears in the ZEPHYR SDK panel on the left. SDKs are registered globally in VS Code settings, making them accessible across any VS Code instance.

Manage Zephyr SDK

In the ZEPHYR SDK panel, you can:

  • Add Zephyr SDK: Register a new SDK to the list.
  • Remove Zephyr SDK: Unregister the SDK from the list without deleting its files.
  • Delete from Disk: Permanently delete the SDK folder from your system (this action is irreversible).
