7 Building the Examples

  1. Setting up host environment.

    2. For Windows Environment: The top level directory in the software package contains a file setupMsysEnv that is used to set the path to the environment variables required to build the examples. Set the path to MinGW installation (TOOL_MINGW_DST), TI Arm compiler (ARM_COMPILER_FOLDER) and the platform development package (PDK_PACKAGES) and optionally to the uboot source directory.

    NOTE

    PDK_packages must point to path to the packages folder in the PDK directory.

    For Linux Environment: The top level directory in the software package contains a file setupLinuxEnv that is used to set the path to the environment variables required to build the examples. Set the path to TI Arm compiler (ARM_COMPILER_FOLDER) and the platform development package (PDK_PACKAGES) and optionally to the uboot source directory.

    NOTE

    For Linux environment, using the boot utilities requires wine utility. If you do not have this installed, install the utility by executing following instruction on your Ubuntu machine.

     sudo apt-get install wine

    PDK_packages must point to path to the packages folder in the PDK directory.

  2. In order to build the examples for all the supported keystone platforms, you can execute "make all". In order to build uboot binaries in addition to boot examples, you can execute "make k2h_uboot" or "make k2e_uboot".

    3. Top level make file supports the following targets:

    k2h_examples : Builds examples for K2H devices k2e_examples : Builds examples for K2E devices utils : Builds boot utlities k2h_uboot : Builds uboot binaries for K2H devices k2e_uboot : Builds uboot binaries for K2E devices

    NOTE

    In Linux environment, if you see errors related to environment variables, check your path to the tools. If that is accurate, ensure that you have saved the file in unix format.

     :set fileformat=unix :wq
