- The author ports Linux to the Sega 32X as a way to improve board bringup skills, motivated by past experiences with Android 5.0 Lollipop on a MediaTek phone.
- The Sega 32X hardware features two SH2 CPUs and 256KB RAM, requiring creative solutions like using flash cart ROM as RAM and software synchronization for SMP support.
- Challenges include toolchain issues, memory constraints, lack of hardware synchronization primitives, and cache coherency, solved with Peterson's algorithm and 68000 as an interrupt router.
- The project successfully boots Linux with SMP support, a console display driver, and a minimal rootfs, despite performance limitations and extensive debugging.
