Build

Clone the BSP Repository

First of all you need a local copy of the BSP repository. This can be either meta-ked-bsp or a custom layer. This guide will use the public meta-ked-bsp BSP repository to build images for our standard and demo hardware.

cd ~
git clone https://git.kontron-electronics.de/sw/ked/meta-ked-bsp.git
cd meta-ked-bsp

Use the Menu to Configure (Recommended)

kas command

In the following we will use the kas-container script to build inside of a container. If you do native builds, you can use the kas command directly instead.

Run the menu command:

kas-container menu

Navigate through the menu using UpDown and select the options you need using Space.

Afterwards use Tab to navigate to the button menu, select "Save & Build", "Save & Exit" or "Exit" using LeftRight and confirm with Enter.

The configuration is saved to .config.yaml which is excluded from being tracked in Git.

The configuration in .config.yaml will mainly consist of references to other configuration files in the kas subdirectory.

Run the Build

If you selected "Save & Build" in the configuration menu, a build will be started automatically. Otherwise you can start a build with:

kas-container build .config.yaml

Now kas will fetch all repos specified in the configuration, initialize the build environment and launch bitbake.

Select Configuration Files Manually

Instead of using the menu command and creating a .config.yaml you can also select the existing configuration file(s) manually.

The following command produces the same result as when selecting the option "Kontron Electronics SL/BL/OSM i.MX8MM" via the menu.

kas-container build kas/ked-mx8mm.yml

Using the shell Command

Instead of using the build command to start bitbake, you can also use the shell command to instruct kas to drop you to a shell inside the build environment.

kas-container shell .config.yaml

Once inside the shell, you can run any bitbake command you like.
