Make an Embedded Linux System which can use GCC to compile a hello world.
This was the start of a multi month project to get a much better grasp on high speed digital electronics, Linux, much more complicated PCB design, BGA devices, and because it is just so damn cool.
The github includes a very rough initial documentation pass. I will be managing this for the next few months while working on my website and writing a full blown write-up.
This was originally meant for myself as a personal project, but I was able to take an independent study class in my Computer Science program and use "Make an Embedded Linux System which can use GCC to compile a hello world" as the project. I was late by a few months, but finally got it working.
Surprisingly enough, now that I understand the general overview of how to make a Linux capable system, it's far less difficult than when I first imagined. Sadly, I couldn't really find a full blown writeup online of how to do this from start to end in detail, which is what really slowed me down. So, I am hoping that my eventual writeup will fufill that niche as well as help others going through the same process.
If you all have any questions or spot any mistakes/issues (of which there are probably many since I am still very new to electronics), let me know and I will happily try to answer or clean it up. If you are reading this and it has been a few days, weeks, months, or years, feel free to message me!
