Also, RiscV has matured and had upstream gcc and linux kernel support. It is also completely GPL'd and you can run it on an FPGA.

This project is cool and done with the correct intentions by the author, but there are other projects with the same correct intentions that are already much farther along.

Why do you compare my A2Z project with RISC-V? Have you read the pages and the blog posts on hackaday? Have you understood what A2Z is? A2Z is (only) a DIDACTIC project. The goal is learning by doing, and therefore the goal is to reinvent the wheel, just for fun. The "learning by doing" method is the best method I know. The principle is absolutely NOT to take an existing CPU or OS and assembling existing parts. And of course, I have learned a lot of things with this method. That's why I'm sharing this project. I hope some people will begin such project on their own, and learn as much as I did.
