A "minimal" ARM cortex-M firmware in Zig.
Get GNU Arm Embedded Toolchain and Zig in PATH and type:
make
running on a bluepill
Run OpenOCD on a terminal:
openocd -f /usr/share/openocd/scripts/interface/stlink-v2.cfg -f /usr/share/openocd/scripts/target/stm32f1x.cfg
Open your favorite GDB:
arm-none-eabi-gdb firmware.elf -ex 'target extended-remote :3333'
load
r
Bonus: you can type make inside gdb and load it again.
You can try uncommenting the line below (in the Makefile) to use the lld (don't forget to comment out ld):
zig build-exe ${BUILD_FLAGS} $(OBJS:%=--object %) --name [email protected] --linker-script ${LINKER_SCRIPT}
# arm-none-eabi-ld ${OBJS} -o [email protected] -T ${LINKER_SCRIPT} -Map [email protected] --gc-sections
a) Shouldn't the Makefile...
A: lalalala
b) How do I flash this?
