Blink (on-board LED)

An original public-domain (CC0) program, hand-authored in Xtensa LX6 assembly. It enables GPIO2 as an output through the ESP32 GPIO block (0x3FF44000) and toggles the on-board LED forever with a delay loop, logging LED GPIO2: ON / off over UART0. The microcontroller "hello, world" — a tight target for single-stepping the Xtensa core and watching the GPIO_OUT register change.
