PIxhawk Pilot Support (PSP) configuration (Linux 16.04 with Matlab 2017b)

1. Download Pixhawk Support Package and install it [1]

(1) Open Matlab
(2) Change Matlab file directory to the path of  "PX4PSP_v3......"
(3) Click and install

2. Set linux build environment

(1) Install gcc-arm-none-eabi v5.4.

wget https://github.com/SolinGuo/arm-none-eabi-bash-on-win10-/raw/master/gcc-arm-none-eabi-5_4-2017q2-20170512-linux.tar.bz2

tar -jxf gcc-arm-none-eabi-5_4-2017q2-20170512-linux.tar.bz2

exportline="export PATH=$HOME/gcc-arm-none-eabi-5_4-2017q2/bin:\$PATH"

if grep -Fxq "$exportline" ~/.bashrc; then echo " GCC path already set."; else echo $exportline >> ~/.bashrc; fi

. ~/.bashrc

(2) Install dependencies

source ubuntu_sim_common_deps.bash

3. Create a empty folder for storing the firmware

ex: 

4. Build firmware
