Does anyone know how to make your own firmware? I mean, How do I program my own firmware for an MP4 player for example?

Solution 1

Why do you want to do that? Do you buy bare computer and write your own OS?

Firmware is basically an embedded programming which can do either simple tasks or more complicate tasks. By all means having your own MP4 player is not trivial coding.

Comment from OP:
I'm completely sure that it is not trivial coding but I would like to make some code to generate firmware, do you know how to do it?

@Sandeep. Initially I thought you were pretending to be the OP, until I was his answer. It would have been funny if it was your comment. :-)

Firmware is actually very specific to the hardware that it is developed for. This could be the chips, the peripherals, or anything else in the device. One thing that is close to firmware development is some of the robot coding like the lego robots. I have created firmware for a PC that I put together by hand for school, and at work for PCI/AGP cards that we develop. Overall, it is not much different than normal coding, but you have to be aware of the space on the device that you are taking up with the code and how much memory you are using for storage. It can be tricky, but not alot different than standard C/C++ coding for a PC.
