Zortex-M33

Minimal bare metal Zig for Arm Cortex-M33 using STM32U585AI on the B-U585I-IOT02A board.

Inspired by and builds on the embedded_zig project.

Tested with Zig v0.14.x and v0.15.x.

Using OpenOCD

openocd -f interface/stlink.cfg -f target/stm32u5x.cfg -c "program zig-out/bin/blinky.elf reset exit"

Flash and debug blinky example using GDB

Start OpenOCD

openocd -f interface/stlink.cfg -f target/stm32u5x.cfg
