CSSE4011: Tute 2.2 - Application Building Tips

1.0 Motivation

This tutorial will focus on modifications to the CMakeLists file to streamline the application development process.

2.0 Setting Build Options

Note that these should be added to the top of the CMakeLists file. Additionally, there are other ways to include config files and devicetree overlays. Refer to a application development and device tree guides for more.

2.1 Boards

A board to develop can be specified within the top level CMakeLists file as below, the particular name for the board can be found under Zephyr Supported Boards -> boardname or here.

set(BOARD board_name)

set(BOARD particle_argon)

With this set, west build can now omit the '-b board_name' option. By just using 

west build

an application can be created for the particle_argon.

2.2 Runners

The flash runner for the board can be set using the below, within the CMakeLists file.

set(BOARD_FLASH_RUNNER runner)

set(BOARD_FLASH_RUNNER jlink)

This allows for west flash to be ran with about specifying the '-r runner' when invoked. 

west flash

2.3 Config Files

Config option files (ending with .conf), can be added to the CMakeLists file using,

set(CONF_FILE files.conf)

set(CONF_FILE general_config.conf usb_config.conf uart_shell_config.conf)

2.4 Devicetree overlays

Devicetree overlay files can be added to the build system using,

set(DTC_OVERLAY_FILE overlay.dtsi)

set(DTC_OVERLAY_FILE dts/spi3.dtsi)
