Install Operating system on raspberry pi 0w¶

To install Operating system on Raspberry pi there are many website describing how to do. For french noobies, better explanations here : https://edutechwiki.unige.ch/fr/Installation_de_Raspbian

Raspbian Lite¶

The steps are classic :

Dowloading image from https://www.raspberrypi.org/downloads/raspbian/ and download the "Raspbian Stretch Lite" version. We will not use X servers and other desktops tools. Just console.

wget https://downloads.raspberrypi.org/raspbian_lite_latest

unrar the .zip

tar -xvf /my/raspbian/iso.zip

Install it on SDcard from your desktop pc https://www.raspberrypi.org/documentation/installation/installing-images/

dd bs=512 if=/iso/place/on/my/computer of=/dev/mysdcard conv=sync

activate ssh, to create the ssh file in boot to activate it

$ touch /Volumes/boot/ssh

activate ssh by usb,

edit config.txt @ the root of the sd card and add "dtoverlay=dwc2" or directly

echo "dtoverlay=dwc2" >> /path/to/my/sd/card/config.txt
echo "modules-load=dwc2,g_ether" >> /path/to/my/sd/card/cmdline.txt

edit the wifi config file to set your personnal SSID and psswd

vim /media/$USER/rootfs/etc/wpa_supplicant.conf

add :

country=GB
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
ssid="MyWiFiNetwork"
psk="password123"
}

eject sdcard :

$ sudo diskutil eject /dev/mmcbbtruc0
Password:
Disk /dev/mmcbbtruc0 ejected`

start pi0 : put the sdcard in pi0 and plug it with usb to your computer

connect to pi0 (default psswd is raspberry)

ssh pi@raspberrypi.local

extend file system

$ sudo raspi-config

in "7 Advanced options", select "A1 Expand filesystem", when operation done, reboot and reconnect to ssh.

update packages

$ sudo apt-get update
$ sudo apt-get upgrade

change password

passwd
