This DIY comment really annoyed me, as I have seen some companies inherit a dumpster-fire of legacy code auto-generated from Yocto (or some other flavor of the week), that would make even the most devout fan-boy blush. Or you can integrate a stripped FreeRTOS, BSD, VxWorks, or Linux kernel… and actually work on getting your core project running.Īs with all OS, the use cases will certainly evolve… it is foolish to believe an individual is more thorough than millions of users, and thousands of developers. Posted in Raspberry Pi Tagged operating system, qemu, raspberry pi Post navigation Even if you don’t want to build a general-purpose operating system, you might want to try your hand programming the Pi at the “bare metal” level. This isn’t the first OS tutorial for the Pi that we’ve seen. Want to know about the Pi’s configuration? The organization of the framebuffer? Which interrupts are available? All that information is there. ![]() There’s quite a bit of ancillary information about the Pi, also, which is great. The operating system isn’t very complex, but it does boot, organize memory, displays on the screen, handles interrupts, and manages processes. When you are ready, you can set up a bootable SD card and try your work on a real device. QEMU emulates a Raspberry Pi so you can do the development on a desktop PC and test in the virtual environment. One thing that makes it easier is the development environment used. has a tutorial on how to create a simple operating system for the Raspberry Pi. Writing an operating system is no small task, but like everything else it is easier than it used to be. ![]()
