Learn how to build an embedded Linux-based Qt application and ...

Module 2: Setting up your build environment and learning how to build
MQX and Linux OSs on your development host. How to build a state-ofthe-art
UI for on-screen controls using Qt Embedded for Linux.
In this session, attendees will set up their host development environment with desktop tools
including Factory and ARM DS-5 that enable developers to build MQX and Linux OSs and assist in
the development of value-add software.
Using Qt WYSIWYG features, attendees will design a UI for a security surveillance application that
provides end users with information on capture and displayed feed along with various controls to
manipulate the device’s behavior. The application will leverage hardware accelerated features of
the Vybrid SOC.
What you will learn:
• How to setup your host environment to cross compile MQX and Linux
• Qt Embedded for Linux as an example of a WYSIWYG UI design
- Qt primer
• How to use a modern IDE to develop an application
• How to modify a filesystem design to meet your custom project needs
• How to rebuild the complete Linux platform from sources in a repeatable way
• How to manage Linux kernel builds with custom patches
Hands-on exercises:
• Setting up the system and application development environment
• Building:
- MQX
- Linux
- Qt based HMIs
• Testing and debugging of the application
Module 3: How to capture and display video using hardware accelerated
features in your security surveillance application. How to build MQX
application and how to pass information between OSs with MCC layer.
The Qt application developed controls various functions of the security surveillance system that
will be displayed on the first framebuffer that’s available, and its appearance will be mixed with a
video feed that plays on a second framebuffer. Attendees will learn about the GStreamer framework
including the basics of how to construct a video pipeline for capture and video playback.
In the final step in this module, attendees will develop code that connects Qt widgets with the
GStreamer framework. Attendees will learn how to build an MQX application that monitors a light
sensor and how to pass this information to Linux via the Multi-Core Communication (MCC) layer.
What you will learn:
• How to build an application for a MQX RTOS
• How to pass information between OSs with MCC layer
• How to combine all developed Linux components into a final product
• How to integrate LinuxLink tools into your corporate systems (case study)
• What is the GStreamer framework, and how to use it
• How to work with hardware accelerated features of the Vybrid processor
Hands-on exercises:
• Monitoring a light sensor under MQX RTOS
• Passing information between MQX and Linux OSs via the MCC layer
• Starting a video capture from a Qt application
Module 4: How to optimize, test and integrate the solution for fast boot
and quick deployment.
The last module will focus on Linux platform integration and explain how to integrate the solution
for quick deployment using an SD card. Attendees will learn about common Linux techniques for
achieving a small footprint end product with a fast boot time, including the development of scripts
used to auto launch different features of the product at boot time.
What you will learn:
• How to combine all developed Linux components into a final product
• How to optimize for deployment, footprint and boot time
• How to modify bootloader settings for deployment in an SD card
• How to integrate LinuxLink tools into your corporate systems (case study)
Hands-on exercises:
• Building a Linux image for SD card deployment
• Linux kernel optimizations for fast booting
