I made my paper "Agile Methods and Firmware Development" available. You can find a link to the paper from the sidebar, under "My Papers". This is my initial review and analysis of different software lifecycle models and their applicability to firmware development as part of Ph.D. studies. Paper is dated a few years back. One might say that the current journey started upon writing this paper.
Abstract— The size and complexity of software continues to grow
at a steady pace. This is also true for software embedded in our
everyday electronics, which we have called simple devices. The
term firmware is used to describe the low-level software in
embedded systems. It may even be hard to divide firmware and
actual hardware. Software development for such a target has
special characteristics such as a culture of hacking, small teams
and multiple hats, co-design issues, one-time designs, correctness
and robustness requirements, lack of tools and unconventional
customers. Software process models have been studied also in
this environment to ease the pain of developing more complex
systems. I introduce four currently used methods to develop
firmware; build-and-fix, waterfall, ROPES and RUP SE.
Agile methods are getting a lot of attention in the software
development community at the moment. I review the agile
methods which are most documented. The suitability of these to
firmware development is evaluated. It is also analyzed whether
firmware development could benefit from agile methods.
It is shown that agile methods are not the new cure-all solution
to firmware development, but they are applicable. Their full use
needs modification and innovative thinking. It is, however, shown
that firmware development can surely benefit from the usage of
