| Had orientation and met other REU students. |
| Began researching the raspberry pi 1 version of the framebuffer. |
| I got the graphical shell working on the raspberry pi 1. |
| Unfortunately, we ran into an issue where we could compile the kernel, but the kernel didn't link due to missing ARM opcodes in the trig and turtle libraries in the raspberry pi 3 B+ version of Xinu. |
| Thankfully, we found the issue to be that we didn't enable the FPU (Floating-Point Unit) and use the proper ABI (Application Binary Interface) version. This resolved our linking issue. |
| Week 2: June 3 - June 7 |
| Read past papers on Xinu research. |
| Finished implementing the graphics driver, added support for colors in the shell, and fixed issues with the minishell displaying under the turtle sandbox window. |
| Began looking through existing shell documentation in preparation for building a tmux-style program for displaying multiple shell windows. |
| Successfully implemented a system of abstraction whereby the user can spawn and kill multiple discrete shell processes. |
| More investigation is being done into devising an abstraction for allowing each shell to be treated as a separate output device. |
| Week 3: June 10 - June 14 |
