Qualcomm DragonBoard - Configure GPIO

Introduction

DragonBoard™ 410c is the first development board based on a Qualcomm® Snapdragon™ 400 series processor. It features advanced processing power, Wi-Fi, Bluetooth connectivity, and GPS, all packed into a board the size of a credit card. Based on the 64-bit capable Snapdragon 410E processor, the DragonBoard 410c is designed to support rapid software development, education and prototyping, and is compliant with the 96Boards Consumer Edition specification. All this makes it ideal for enabling embedded computing and Internet of Things (IoT) products, including the next generation of robotics, cameras, medical devices, vending machines, smart buildings, digital signage, casino gaming consoles, and much more.

In this tutorial, you will learn how to download and install all libraries to use the GPIO of the boards.

Step by step

Download and install libsoc:

$ git clone  https://github.com/jackmitch/libsoc.git
$ cd libsoc 
$ autoreconf -i 
$ ./configure 
$ make 
$ sudo make install 

Download and install 96BoardsGPIO library:

$ git clone  https://github.com/96boards/96BoardsGPIO.git
$ cd 96BoardsGPIO 
$ ./configure 
$ make 
$ sudo make install 
$ sudo ldconfig /usr/local/lib  

Download and install mraa library:

$ git clone  https://github.com/intel-iot-devkit/mraa.git
$ mkdir -p mraa/build 
$ cd mraa/build 
$ cmake .. 
$ make 
$ sudo make install 
$ sudo ldconfig /usr/local/lib 

Download and install UPM / RESET the board:

$ sudo ln -s /usr/bin/swig3.0 /usr/bin/swig 
$ git clone  https://github.com/intel-iot-devkit/upm.git
$ mkdir -p upm/build 
$ cd upm/build 
$ cmake -DBUILDSWIGNODE=OFF .. 
$ make 
$ sudo make install 
$ sudo ldconfig /usr/local/lib/libump-*
$ sudo reboot

Last of all, the test blink example found in examples folder in 96BoardsGPIO library directory.

$ cd 96BoardsGPIO/examples 
$ sudo python blink.py

Connect LED to pin 23 of the board!

Hope you enjoy!

Thanks.
