We are focus on documentation but learning requires to get your hands dirty. The PC architecture is not common in embedded systems, and although most of the content in these trainings is useful for any Linux system, we will work with the Beaglebone board, and giving full details about the am335x processor (used by the Beaglebone) kernel code.
Although this board is not really expensive (the beaglebone black is 45 US dollars) we will give you the opportunity to work with an emulated system, so you can start doing the exercises without any real hardware. The good news are, if you have a beaglebone board or you plan to get one, all the work done with the emulator can be directly applied to the real board.
