Integration
The Reference Software Stack uses the Yocto Project build framework to build, integrate and validate the Use cases.
The Yocto Project version used by the Reference Software Stack is styhead.
meta-arm-bsp-extras Yocto layer
The meta-arm-bsp-extras layer primarily depends on the meta-arm layer
which implements the fvp-rd-kronos bitbake MACHINE definition to enable
the Arm Automotive Solutions to run on the Arm Reference Design-1 AE FVP
(FVP_RD_1_AE).
meta-arm-auto-solutions Yocto layer
The meta-arm-auto-solutions layer is based on the EWAOL distribution.
It also contains a set of bitbake bbclasses, recipes and libraries to build,
integrate, and validate the Use cases with either or both the
Baremetal and Virtualization Reference Software Stack Architectures
as described in Reference Software Stack Overview.
It depends on a BSP layer such as the meta-arm-bsp-extras layer.
The layer source code can be found at yocto/meta-arm-auto-solutions.
meta-arm-safety-island Yocto layer
The layer meta-arm-safety-island integrates the applications for the Safety
Island using base configuration from the meta-zephyr-core Yocto layer. It
also contains recipes for the Linux kernel modules for inter-processor
communication with the Safety Island.
The layer source code can be found at yocto/meta-arm-safety-island.
Yocto build configuration
A set of yaml configuration files (found at yocto/kas) for
the kas build tool is provided to support bitbake layer fetching, project
configuration and executing the build and validation.
Yocto layers dependency
The following diagram shows the layers which are integrated as part of the Reference Software Stack.
Note that the meta-arm-systemready layer is only required when building
for the Arm SystemReady IR ACS tests.
