Preparation

Ciao,

durante la serata useremo Buildroot per costruire una immagine per un sistema embedded. Buildroot gira esclusivamente su Linux ed ha le seguenti dipendenze https://buildroot.org/downloads/manual/manual.html#requirement che vi invitiamo ad installare prima della serata. Se usate un altro sistema operativo installate Vagrant e tramite queste istruzioni https://buildroot.org/downloads/manual/manual.html#getting-buildroot arrivate con la macchina virtuale pronta.

Se avete una scheda embedded per cui volete costruire l'immagine portatela che magari riusciamo a provarla :)

A giovedì

Logged as gpmacario@hw2457, start a PowerShell and type

"https://buildroot.org/downloads/Vagrantfile","Vagrantfile");
vagrant up
