Re: Aumentar memoria ram y/o swap en Raspberry Pi 2

4 rpis ya son 160€, más las tarjetas, alimentadores. por ese precio yo buscaba algo basado en atom o celeron u otro sistema de bajo consumo que me permitiera tener todo más integrado.

pendrive de solo lectura

Hola

Tenía un pendrive conectado permanentemente a la RPi durante dos años. Ayer falló y al pinchar el pendrive en otros equipos tanto con Linux como con Windows me dice que el pendrive es de sólo lectura y no puedo escribir en el.

¿Alguna solución?
