Location: Follow these instructions on your LOCAL NODE
Download the pi os iso. See https://www.raspberrypi.org/downloads/ (The minimal image. 2020-05-27-raspios-buster-lite-armhf.zip at the time of this tutorial)
Create the bootable sdcard
Be careful with this step! Don't delete things you don't want to delete. Be sure of your of=/dev/(yourdevhere) link.
These commands may help you locate your target.
$ df -h
$ lsblk
Copy the os image to sdcard (this will erase everything on the sdcard) dd is one option, use a disk imaging tool you're comfortable with.
$ unzip 2020-05-27-raspios-buster-lite-armhf.zip
$ sudo dd if=2020-05-27-raspios-buster-lite-armhf.img of=/dev/(yourdevicehere) bs=4M status=progress conv=fsync
or the same thing in one step
$ unzip -p 2020-05-27-raspios-buster-lite-armhf.zip | sudo dd of=/dev/(yourdevhere) bs=4M status=progress conv=fsync
Write cached data to disk.
$ sync
Enable ssh: place a file named ssh, without any extension, onto the boot partition before booting.
(optionally, enable ssh) Open a terminal to the boot partion then...
$ touch ssh
WiFi (hardwired ethernet recomended) (optionally, preconfigure wifi) Open a terminal to the boot partion then...
$ vim wpa_supplicant.conf
Fill in your details..
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=US
network={
ssid="Name-of-your-wireless-LAN"
psk="Password-for-your-wireless-LAN"
}
Be sure to change US to your country code. And use your Name-of-your-wireless-LAN and Password-for-your-wireless-LAN.
Move your sdcard into your pi and power it up.
(after booting, optionally to find the ip address of your pi to access ssh, or you can use a keyboard and monitor, or your router may have a feature you'd be able to find your PI's IP address from.)
$ sudo arp-scan 192.168.1.0/24 -I eth0
Assuming you have arp-scan installed and your nework is 192.168.1.0/24 and your pi is connected on the same network as your eth0 connetion.
login with ssh $ ssh pi@192.168.1.20 (your ip may be different) or with keybord and monitor.
user pi
password raspberry
Initial Configuration
$ sudo raspi-config
- set password
- set localization / keyboard
- set wifi connection (if not using ethernet and not already set)
- enable ssh [if not already enabled from boot ssh file]
If you're using ssh it's a good idea to set only key based ssh.
note: once you're connected with wired or wireless you may find ssh easier to continue from here for copy/paste of commands.
Update system
$ sudo apt update
$ sudo apt upgrade
(be sure you're connected with cabled ethernet first)
Edit /boot/config.txt
$ sudo vim /boot/config.txt
Locate this line
# Additional overlays and parameters are documented /boot/overlays/README
insert
dtoverlay=disable-wifi
dtoverlay=disable-bt
note: older versions of raspbian you may need to use pi3-disable-wifi and pi3-disable-bt instead of the non prefixed versions.
reboot and check that wifi is not available
$ sudo reboot
$ ip a
No wireless device should be listed.
