You can write your own device drivers without a physical hardware. You can just create device special files and you can write drivers for them. As you just a starter, the best thing for you would be to start from a simple kernel module and then writing a simple character device driver. Google it you will get many references to the same. > Even if I write one...how do I test it. Now once you have written it, you can simply read/write on that dummy character device driver and it should work fine for you. Simply by using cat command you can read that file. Its simple. Refer some documets, it will be more clear to you. > What if I at some later stage I want to get involved with more serious Try writing some block device driver or Network driver... Its serious stuff for sure ! > Device Driver programming i.e. go beyond basic drivers...How do I overcome > the challenge of getting a hardware. You have dummy device simulators. You can use them. For example, say you want a MTD device, you can simply create dummy MTD devices ( NAND and NOR) on your machine. There are many other. Pick any of your choice. > people who write Network Drivers...How do they overcome the challenge of > getting and using the hardware. > No Idea.
