Building The Linux Components

Linux for SC5xx uses Yocto to build and package all the components required for you to install Linux on your development board and build your own applications.

Setting Up The Components

To build the components we first setup the environment for Yocto, telling it what we want to build, then we build the components.

To set up the environment for your sc5xx board:

$ cd ~/yocto
$ source setup-environment -m adsp-sc589-ezkit

$ source setup-environment -m <MACHINE> -b <BUILDDIR>

options:

-m <MACHINE>

if you setup the MACHINE, the local.conf would be automatically set to the default template, so make sure to save your own changes in local.conf once you pass this option to the script Supported MACHINE:

adsp-sc573-ezkit
adsp-sc584-ezkit
adsp-sc589-ezkit
adsp-sc589-mini

-b <BUILDDIR>

The default BUILDDIR is “build”, you could pass another dir to the script

If no option passed to the script, the YOCTO would reuse the build/ dir as your default build environment.

Building The Components

To build your components:

$ bitbake <TARGET>

TARGET:: u-boot-adi; linux-adi; adsp-sc5xx-ramdisk; adsp-sc5xx-minimal; adsp-sc5xx-full

Remember add “-C compile” option to bitbake if you want to compile and deploy your images at second time.

Other build rules are summarized on the ADI Yocto Metalayer page.

Warning: Your first build will be slow. Yocto will be downloading all the required sources and building all the toolchains required for the creation of your tools. Subsequent builds will be faster.

The Build Output

The build output can be found in the build/tmp/deploy/images/<MACHINE> directory.
