1.4. Directory Structure Overview

The Processor SDK for Linux contains the following top-level directories and files

├── bin/
├── board-support/
├── example-applications/
├── filesystem/
├── k3r5-devkit/
├── licenses/
├── linux-devkit/
├── Makefile
├── makerules/
├── manifest/
├── Rules.make
├── setup.sh*
└── yocto-build/

These directories contain the code and tools used to develop for Processor SDK devices.

  • bin - Contains the helper scripts for configuring the host system and target device. Most of these scripts are used by the setup.sh script.

  • board-support - Contains the SDK components that need to be modified when porting to a custom platform. This includes the kernel and boot loaders as well as any out of tree drivers.

  • manifest - Contains software manifest files

  • licenses - Contains software licenses

  • example-applications - Contains the sources for the TI provided example applications seen during the out-of-box demonstration.

  • filesystem - Contains the reference file systems. These include the smaller base file system as well as the full-featured SDK file system.

  • linux-devkit - Contains the tools and libraries to speed development for the target device for the ARMV8 architechture

  • k3r5-devkit - Contains the tools and libraries to speed development for the target device for the ARMV7 architechture

  • Makefile - Provides build targets for many of the SDK components from the top-level of the SDK.

  • makerules - Make rules for all the topLevel Makefile build targets

  • Rules.make - Sets default values used by the top-level Makefile as well as sub-component Makefiles.

  • setup.sh - Configures the users host system as well as the target system for development.

  • yocto-build - This directory allows rebuilding SDK components and filesystem using yocto bitbake. Refer to Building the SDK section for more details on running yocto builds.
