Browse to the installation folder, enter build folder and follow the instructions in Build Instructions file to build sample applications in one’s build environment.

1. Make sure you're in the build directory (<INSTALLATION_DIR>/build) as so. For example:

   cd ~/AM335xBluetopiaLinuxProduction-4.2.1.1.1.0/build

2. Make a copy of the setup-bt.sample file. For example:

   cp setup-bt.sample setup-bt 

3. Update the TOOLCHAIN_PATH and KERNEL_PATH variables in setup-bt for your environment. For example:

   # Path to local toolchain installation
    export TOOLCHAIN_PATH=~/ am335x/tisdk6.0/linux-development/linux-devkit/sysroots/
   
   # Path to SDK compiled kernel
    export KERNEL_PATH=~/ am335x/tisdk6.0/linux-development/board-support/linux-4.19.38+gitAUTOINC+4dae378bbe-g4dae378bbe/

4. Enable or disable the builds for certain projects and additional configuration settings in the 'proj/proj-defs.mak.

   For example to update the DEVICE variable in the proj/proj-defs.mak file to build for either the CC256x or Wilink8 platform (default), by commenting out the unwanted platform.

   DEVICE = wl18xx
   #DEVICE = cc256x

5. Update the TOOLCHAIN_PATH_NATIVE and TOOLCHAIN_PATH_TARGET variables in the proj/toochain-defs.mak file. For example:

   TOOLCHAIN_PATH_NATIVE=$(TOOLCHAIN_PATH)/x86_64-arago-linux/
   TOOLCHAIN_PATH_TARGET=$(TOOLCHAIN_PATH)/armv7ahf-neon-linux-gnueabi/

6. Run the following command to configure the environment from above settings (from the build directory).

   source configure.sh
