BBB Flashing Loop

0

Por lo general, no tengo problemas para actualizar mi BBB con la SD que tengo. Lo hago todo el tiempo, y funciona en la mayoría de los tableros. Sin embargo, ocasionalmente se atasca en este "bucle".

Destellará el dispositivo con éxito, realizará la limpieza y luego se apagará. Sin embargo, en lugar de permanecer abajo como todas las otras veces, se reiniciará instantáneamente, verá la tarjeta SD y comenzará a parpadear nuevamente. Sé que parpadea con éxito porque si lo miro y desconecto la energía antes de que llegue a la etapa de flasheo en el próximo ciclo ... Puedo sacar la tarjeta SD y arrancarla, y todo está dorado.

Aquí está la salida de mi consola durante / después:
