Buenas, por fin me llego el usb to rs232,
yendo al grano, dejo aquí el log de arranque:

detalle curioso, en la carcasa del router pone que la revisión de hardware es: R01A, pero danube me dice que es la 01A, supongo que a efectos prácticos será lo mismo.

al parecer no es capaz de encontrar el punto para iniciar la imagen, supongo que seria en 0x000000020000, no? o bien en 0x80006000?
