Untitled.video.-.Made.with.Clipchamp.mp4

If you want to link your program without the default C library (libc), startup files, and linker script, you can use the following arm-none-eabi-gcc command:

arm-none-none-eabi-gcc -mcpu=cortex-m3 -mthumb -std=c11 -O1 -g -c main.c -o main.o
arm-none-none-eabi-gcc -mcpu=cortex-m3 -mthumb -std=c11 -O1 -g -c boot.c -o boot.o
arm-none-none-eabi-gcc -nolibc -nostartfiles -T linker.ld -Wl,-Map=blink.elf main.o boot.o -o blink.elf
