TQMa64xxL - YOCTO Linux BSP documentation

Build Yocto SDK

Building the Yocto SDK for the STKa64xxl requires a Yocto build environment configured for meta-tq or ci-meta-tq. Follow the TQMa64xxL Yocto quickstart guide instructions to setup the build environment.

The SDK has to match the actual rootfs configuration, otherwise you may expect difficulties while debugging an application.
So if the rootfs configuration is changed, the SDK must be rebuilt and installed again.

To generate the Yocto SDK for the default image tq-image-generic, use the following command in your build space:

bitbake -c populate_sdk tq-image-generic

Yocto generates an SDK install script which is available after building in the following path of your build directory ../tmp/deploy/sdk/.
Navigate to the script and execute it to install the SDK. The code block below shows the install script name if the default image tq-image-generic has been used to generate the SDK.

Keep in mind that the SDK has to match your target image.

./tq-dumpling-ti-glibc-x86_64-tq-image-generic-aarch64-toolchain-4.0.6.sh

By default the sdk will be installed to /opt/dumpling-ti/4.0.6/
The install path can be changed during the install process.

If the SDK is used in a new shell session, source the SDK environment setup script e.g. when the SDK has been installed to the default path /opt/dumpling-ti/4.0.6/

source /opt/dumpling-ti/4.0.6/environment-setup-aarch64-tq-linux
