Build overview

[中文]

basic concept

  • project - Specifically the directory or subdirectory under armino/projects/,which contains all the files and configurations needed to build an executable application,as well as other supporting files such as partition tables, data/filesystem partitions, and bootloaders.

  • Project configuration - Specifically, the sdkconfig.h file generated in the build directory during the build process.

  • application - is an executable built by ARMINO. A project typically builds two applications : the project application (the main executable file, i.e. user-defined firmware) and the bootloader (the project application that starts and initializes).

  • components - is modular and self-contained code that is compiled into a static library (.a file) and linked into the application.

  • Target - Specifically refers to the hardware device that runs the built application, such as bk7236, bk7258 etc.

Project example

- armino/
    - components/
    - include/
    - middleware/
        - arch/
            - bk7236/
                - bk7236.defconfig
                - ...
    - projects/
        - my_project/
            - config/
                - bk7236/config
                - bk7258/config
            - CMakeLists.txt
            - Kconfig.projbuild
            - main/
                - main.c
                - Kconfig
                - CMakeLists.txt
            - components/
                - c1/
                    - c1.c
                    - Kconfig
                    - CMakeLists.txt
                - c2/

Trigger a build with make

Run make in the armino root directory. The most commonly used make commands are as follows:

  • make bkxxx - Build the target bkxxx, and the project is the default project armino/projects/app.

  • make bkxxx PROJECT=a/b - Build bkxxx, the project is armino/projects/a/b

  • make all - build all targets

  • make cleanbkxxx - clean target bkxxx

  • make clean - clear all targets

The make build is to indirectly call the armino tool through armino/Makefile to build, which saves the trouble of setting environment variables when building with the armino tool. It is recommended that you build in this way.

You can also execute the make command in the project directory without specifying a project:

  • make bkxxx - Build target, the project is the current project

  • make clean - Clean up the build directory
