Learning project on a STM32H7S78-DK

Long-term goal is to write a UF2 bootloader and maybe a keyboard firmware on top to learn low-level stuff and, specially, zig.

File structure

• modules - Building blocks
  • application - (TBD) So far, just a playground for random code ideas
  • bootloader - (WIP) Implementation of UF2 bootloader, into the external OSPI flash
  • common: crt0.c-like logic
    • Fill data regions and some other initial setup
    • Set up zig's logging and panic
    • Call into main
  • hal - STM's vendor HAL + some zig wrappers
• ld - Linker scripts
