Making my first embedded Linux system


End-to-end documentation of a journey from no PCB experience to fabricating my own Linux-ready system that can boot the latest mainline kernel. This article is the recommended reading for someone building their first embedded Linux board. F1C100s SoC is used for this sample board.

Open Table of contents While I’m not claiming that my design is something that should immediately go into production and be used to manage the treatment of hospital patients, I do think my prototype at least boots and runs Linux and if you’re reading this article, that’s probably your only goal to start with. Programming would fail until I figured out there’s a parameter to slow down the data rate of the code upload to the MCU, and once I did that, the breadboard setup worked just fine. This was an extremely hacky journey, but it satisfied a lot of my curiosity, and seeing the PCB come to life after all the studying and designing and waiting for the fabrication was a great feeling.
