A practical introduction to Linux Device Drivers
Loadable kernel modules and statically linked modules
Comparison between statically linked modules and loadable kernel modules
Statically linked modules
- They are linked to the kernel images
- They are loaded as part of the kernel during boot time, so there is no need to access them via some root file system
- For implementing any changes to statically linked modules, one needs to edit, recompile the kernel and afterwards reboot to load the new Linux Kernel
Loadable Kernel Modules (LKM) = dynamic modules
- They utilize by convention the suffix .ko which stands for “kernel object”
- The Loadable Kernel Modules consist of files in the file system with the extension .ko …
This tutorial explains the manner to deploy cross-platform projects made with the Qt framework to macOS Operating Systems using macdeployqt.
Set up the environment
- operating system information (macOS)
This tutorial explains the manner to deploy cross-platform applications made with the Qt framework (Qt Widgets or Qt Quick/QML) to mobile phones or tablets running Android. This article uses Qt Creator running on Windows Operating System as the tool for deployment.
Android is a mobile operating system based on a modified version of the Linux kernel and other open source software, designed primarily for touchscreen mobile devices such as smartphones and tablets.

In this article, I am going to walk you through the process of setting up the Yocto Project to fetch the necessary content and build an Embedded Linux distribution supporting the GStreamer framework. Furthermore, I shall provide you with command-line examples to test-run the ability of GStreamer to run various sorts of multimedia.
Introduction
Gstreamer is an open-source multimedia framework that can be used to build all kinds of media applications (e.g. media playback, streaming, editing). The framework is designed to simplify the handling of video and audio or both simultaneously.
GStreamer works on with all major operating systems like Linux…

There will be times when you want to enable certain hardware peripherals early in the execution of your Embedded programs.
It takes an amount of time for your little embedded device to load the Root File System until you have the operating system running. Just before the root file system is set up, you can still “order” your embedded device to do stuff you want by modifying the U-Boot program.
My example uses Beaglebone Black as an embedded device of choice. …
