Blink (on-board LED)

A tiny original public-domain program, written in C and compiled with clang for the Arm Cortex-M33 (thumbv8m.main). It routes GPIO25 to the SIO function, enables its output, and toggles the on-board LED forever with a delay loop — the microcontroller "hello, world". A tight target for single-stepping the Cortex-M33 and watching the SIO GPIO registers change.
