cross_toolchain

This project will install the Hexagon SDK 3.0, Hexagon cross compiler, gcc 4.9 ARMv7hf cross compiler, and an ARMv7hf sysroot for Snapdragon Flight application development.

SDK Installation

Clone this project:

git clone https://github.com/ATLFlight/cross_toolchain.git
cd cross_toolchain

Download the Hexagon SDK v3.0 from here to your cross_toolchain/downloads location. (You need to create an account if you don't have one).

Download the latest version of the qrlSDK file from here to your cross_toolchain/downloads location. (You need to create an account if you don't have one).

Run the installer

./installsdk.sh --APQ8074 --arm-gcc --qrlSDK

This will install:

• Hexagon SDK [HEXAGON_SDK_ROOT]: ${HOME}/Qualcomm/Hexagon_SDK/3.0
• Hexagon Tools [HEXAGON_TOOLS_ROOT]: ${HOME}/Qualcomm/HEXAGON_Tools/7.2.12/Tools
• ARMv7hf cross compiler: ${HEXAGON_SDK_ROOT}/gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf_linux
• qrlSDK: ${HOME}/Qualcomm/qrlinux_sysroot/merged-rootfs

You can re-run installsdk.sh as many times as you like and it will only install missing pieces and then display the environment variables to set.

If you omit --arm-gcc or --qrlSDK in subsequent runs, these packages will be removed from the installation. Running subsequent times without --trim or --zip will have no effect.

Triming the HEXAGON SDK and HEXAGON Tools installation

If you run

./installsdk.sh --APQ8074 --trim --arm-gcc --qrlSDK

It will remove all non-essential files and directories for building for Snapdragon Flight from the SDK and Tools installation. This can be useful if you are for instance wanting to create a minimal install if the SDK and Tools for a CI test image.

You can also create a zipfile of the SDK:

./installsdk.sh --APQ8074 --trim --zip --arm-gcc --qrlSDK
