0x0: Intro to Virtual Development Board building

| Comments


There are many reasons why ambitious programmers should care about huge rush in embedded market. IMO there is great potential in it. I don’t want to go deep into this but take a look at all tablets, phones, smart TVs and other cool stuff like wireless in you washing machine or refrigerator (ok this two are right now only a gadgets :) ). This is all embedded. Another thing is that wages of experienced embedded developers are really high.

This environment is very interesting. A lot to learn, a lot to do, so why not get your hands dirty ?

First question: How to start ?

To do real embedded development, to learn the most, you simply buy hardware like all this ${animal}board (animal={panda,beagle,hawk}). This is the best way but if you’re beginner (like me) you probably don’t want to spend $50 for stuff that you throw away after month because you don’t like to deal with it or problems are not on your level, than maybe you should take a look around and wonder if it is possible to build virtual environment to check what kind of problem you may encounter learning embedded ? BTW this is cheap and fun, so potential ROI is big enough to try.

IMHO this is where world going: proof of concept embedded platforms affordable for common man (not only for US/West Europe), testing environment based on virtualized/emulated solution, to check basic features, speed up testing, development and deployment. That’s why we see so active development of software like Qemu/KVM.

Virtual Development Board – table of contents

I realize that it is achievable and I will learn a lot trying to implement this idea. Finally I was convinced reading this two years old article on eLinux.org.

I decide to divide this article on few parts because IMHO it was to big to read it at once. Also people interesting in particular topic won’t have to scrolling >2k words post. List of all articles in this series:

  1. Qemu as an environment for embedded board emulation
  2. Toolchain for Virtual Development Board
  3. Embedded board bootloader
  4. Linux kernel for embedded system
  5. Qemu network configuration and tftp for Virtual Development Board
  6. Root file system for embedded system


At the and of this intro I want to give big kudos to all those hackers without whom creating this article would not be possible. Thanks for sharing your knowledge. Every time when I use knowledge that found by googling I’m trying to stick link for further reading.
