In addition, many device drivers are available for Linux, which could be used directly or as a starting point for your target devices.

The GNU 1 project provides a wealth of development tools that support Linux and are also open source.

With the introduction of Linux into the embedded sphere, it has become possible for the semiconductor company itself to port an operating system to a new processor, since the source code for the Linux kernel is available as open source. In addition, the peripherals around the processor required drivers that had to be developed for the specific operating system. Usually the operating system company also provided these tools. The other issue was with the development tools (compiler, debugger, simulator, and so on) for the given processor. If a new processor was designed and developed by a semiconductor company, they had to depend on an operating system company to port their operating system to the new processor. Until now, most embedded operating systems have been proprietary. This article explains the work involved in porting Linux to a specific embedded system and how it was done for one embedded system in particular. Many commercial vendors specialize in porting Linux to embedded systems. Linux is gaining in popularity in embedded systems. Why pay someone to port Linux for you? Here's one Linux how-to no embedded programmer should miss.
