Editor's Note: Linux remains an attractive option for embedded systems developers. In fact, industry surveys such as the Embedded Market Study by UBM (EDN's parent company) consistently show interest ...

In previous articles, we looked at how to configure the kernel as well as the key components of an embedded operating system (OS). This new article focuses on the hardware components of embedded Linux ...

[Johannes 4GNU_Linux] has been filming a video series on how to write Linux device drivers for a couple of years now, but luckily, you won’t need that long to watch them or to create your own driver.

The Linux USB subsystem has grown from supporting only two different types of devices in the 2.2.7 kernel (mice and keyboards), to over 20 different types of devices in the 2.4 kernel. Linux currently ...

One of the highly debated subjects with Windows and Linux is with device support. The two have different methods of how drivers are created and implemented into the operating system. With Windows, ...

This paper describes a methodology for automatically generating device drivers for embedded systems. We formally specify the device behavior and attributes in an input specification called DPS (Device ...
