AVR ATMEGA328p Ejemplo parpadeante

Quería probar un simple guión parpadeante en mi ATMEGA328p. La configuración del tablero de pruebas (probado y funciona bien). Pero el LED no parpadea. Probé los voltajes a través del tablero y están apareciendo con 5V como se esperaba. La respuesta avrdude también se espera. Sólo el LED no parpadea. Cambié el chip también, pero esto no tiene ningún efecto. ¿Tienes alguna idea?

También medí el pin LED, pero hay 0V en el pin y espero que cambie a 5V con el código provisto.
