Installation Debian Trixie (debian 13)
A l’aide de raspberry pi imager, écrire limage de Trixie une carte SD (j’ai installé la version desktop).
Boot depuis la carte SD, utiliser l’utilitaire “copy to SD” pour copier la carte SD vers le SSD.
Change boot mode dans raspi-coonfig (cf documentation )
Installation des interfaces
