Development

Building and flashing applications is provided by the west tool, with the exception of the external tasks. We provide tasks in VSCode to make it easier to build and flash applications.

Compiling

Build the binary using one of the following options:

  • Press the hotkey combination, Ctrl+Shift+B (Mac: Cmd+Shift+B).
  • Use the menu system:
    1. Select Terminal > Run Task... from the application menu.
    2. Select Zephyr: Build Application from the drop-down menu.

Alternatively, you can use the west build command from the terminal:

west build -b swan_r5 examples/blinky

Flashing

Local

From the VSCode, use the menu system:

  1. Select Terminal > Run Task... from the application menu.
  2. Select Zephyr: Flash Application from the drop-down menu.

Alternatively, you can use the west flash command from the terminal:

west flash

External

  1. Launch Debug Server (OpenOCD)

    A debugging server opens a port to receive both debug and program instructions. Then, it forwards those instructions to the target device via a in-circuit debugger and programmer, such as the STLINK-V3MINI.

    Execute the following command on your host machine, OUTSIDE the container:

    openocd -f swan_r5.cfg

  2. From the Dev Container, use the menu system:

    1. Select Terminal > Run Task... from the application menu.
    2. Select Zephyr: Flash Application (External) from the drop-down menu.

NOTE: You must flash your device using the STLINK-V3MINI; DFU is not supported.
