Page 21: Operating System And Drivers
For more information, refer to 5.2. Of course, you can order the emVIEW-7/RPI3 without software, so you can choose a Raspberry PI 3 B compatible operating system of your choice and install it manually on a µSD card. (Raspbian recommended) Refer to 5.1.1 on how to install an image from the official Raspberry Pi website. -
Page 22: Installation Instructions
5.2.1 Installation Instructions The installation requires that the emVIEW-7/RPI3 has booted successfully from the Raspbian image on the µSD-card prepared in chapter 5.1.1 and that you have created a backup copy of the µSD-card.
