Building The SDK

This version is under development
In order to build the SDK it is necessary to follow the relevant Quickstart Guide. For instructions, please refer to Linux for ADSP-SC5xx Processors 3.0.0

Preparing the buildtool

Yocto requires the environment to be configured before building is possible.  A setup-environment script in the griffin, gxp or gxp2 folder contains all the required environment settings. 

$ source setup-environment -m adsp-sc589-ezkit

or 

$ source setup-environment -m adsp-sc589-mini

or 

$ source setup-environment -m adsp-sc594-som-ezkit

or 

$ source setup-environment -m adsp-sc598-som-ezkit

Sourcing the script will configure your build environment and create a build folder along with a local build configuration file.  See the Yocto Manual for further details.

Note that the build environment needs to be sourced once only before building.  If later working in a different terminal the setup-environment script should be sourced again.  If sourcing the setup-environment script is done without specifying the machine Yocto will reuse the previous configuration settings and retain any changes made to the files in the conf folder.


Building the SDK

The SDK can be built for the adsp-sc5xx-minimal image or the adsp-sc5xx-full image. To build the SDK for the adsp-sc5xx-minimal image invoke bitbake from within the build directory created previously. 

$ bitbake adsp-sc5xx-minimal -c populate_sdk

or for the adsp-sc5xx-full image 

$ bitbake adsp-sc5xx-full -c populate_sdk

When the build has completed you will find a set of files in the <BUILD_DIR>/tmp/deploy/sdk directory. For example, the full image on SC594: 

$ ls tmp/deploy/sdk
adi-distro-musl-x86_64-adsp-sc5xx-full-cortexa5t2hf-neon-adsp-sc594-som-ezkit-toolchain-4.0.1.host.manifest
adi-distro-musl-x86_64-adsp-sc5xx-full-cortexa5t2hf-neon-adsp-sc594-som-ezkit-toolchain-4.0.1.sh
adi-distro-musl-x86_64-adsp-sc5xx-full-cortexa5t2hf-neon-adsp-sc594-som-ezkit-toolchain-4.0.1.target.manifest
adi-distro-musl-x86_64-adsp-sc5xx-full-cortexa5t2hf-neon-adsp-sc594-som-ezkit-toolchain-4.0.1.testdata.json

The adi-distro-musl-x86_64-adsp-sc5xx-full-cortexa5t2hf-neon-adsp-sc594-som-ezkit-toolchain-4.0.1.sh is a self-extracting archive containing the SDK.


Installing the SDK

Invoke the self-extracting archive. It will default to installing to /opt/adi-distro/4.0.1 but gives you the option to select your own install folder during the installation. For the minimal image on SC594 

$ ./adi-distro-musl-x86_64-adsp-sc5xx-full-cortexa5t2hf-neon-adsp-sc594-som-ezkit-toolchain-4.0.1.sh
Poky (Yocto Project Reference Distro) SDK installer version 4.0.1
=================================================================
Enter target directory for SDK (default: /opt/adi-distro/4.0.1):
The directory "/opt/adi-distro/4.0.1" already contains a SDK for this architecture.
Extracting SDK............................................................................................................................................................................done
Setting it up...done
SDK has been successfully set up and is ready to be used.
Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g.
 $ . /opt/adi-distro/4.0.1/environment-setup-cortexa5t2hf-neon-poky-linux-musleabi

Your SDK is now installed.
