5 Headerless Setup

This chapter guide to setup and bringup new raspberry pi with raspberry pi os (bulleseye).

5.1 Requirements

  • Laptop/Desktop with sudo permission with Ubuntu 18 and above with 8 GB SSD/HDD and 4 GB RAM
  • Min 8 GB SD Card
  • SD card reader
  • USB to UART Cable
  • Raspberry PI
  • Raspberry PI Power Adapter
  • Image flashing tool(etcher APPIMAGE). download from link
  • gparted tool to create sd card partation.

5.2 Get Raspberry pi OS

Download raspberry pi os from link.

5.3 Prepare SD Card

5.3.1 using balenaEtcher

Insert SD Card on laptop

Run etcher for flashing image.

 chmod +x balenaEtcher-<version>-<arch>.AppImage
 ./balenaEtcher-<version>-<arch>.AppImage

it will show popup

Screenshot

Click On Flash from file, now select image file and click on Open

Now Select Target

Screenshot

5.3.2 Using dd command (only for linux)

find the SD card device interface using

 df -h

it will show list of mounted memory devices

TODO Attach pic

 sudo dd if=<raspberry-pi.iso> of=<sd-dev-interface> bs=1M; sync

5.4 Enable Serial Console

To enable serial console, you need to add configuration in config.txt file located in boot partation(first partation).

 $ vim /boot/config.txt

At the bottom, last line, add enable_uart=1

5.5 Enable Ethernet HotPlug

To enable serial console, you need to enable ethernet hotplug to access your device over network.

 $ vim /etc/network/interfaces

and add following contents

And add following

auto lo 
iface lo inet loopback

allow-hotplug eth0
iface eth0 inet dhcp

5.6 Enable SSH

Older Version of Raspberry pi os

For headless setup, SSH can be enabled by placing a file named ssh, without any extension, onto the boot partition of the SD Card. When the Raspberry Pi boots, it looks for the ssh file. If it is found, SSH is enabled and the file is deleted. The content of the file does not matter; it could contain text, or nothing at all.

Raspberry Pi OS Bullseye

Bydefault Bullseye does not have any user so we need to add user before configuring ssh. to add user, write below content in /boot/userconf.txt

 pi:$6$c70VpvPsVNCG0YR5$l5vWWLsLko9Kj65gcQ8qvMkuOoRkEagI90qi3F/Y7rm8eNYZHW8CY6BOIKwMH7a3YYzZYL90zf304cAHLFaZE0

user will be created on very first bootup bootup. with credential

username: pi

password: raspberry

now ssh can be enabled by placing a file named ssh, without any extension, onto the boot partition of the SD Card. When the Raspberry Pi boots, it looks for the ssh file. If it is found, SSH is enabled and the file is deleted. The content of the file does not matter; it could contain text, or nothing at all.
