Install on raspberry

Revision as of 11:46, 23 December 2020

Short note on installation of (parts of) mobotware on Raspberry Pi (or Beagle-bone)

Prerequisite

• Raspberry pi - version 3 or 4
• SD-card preferably at least 16Gb
• Monitor with HDMI (version 3) or micro HDMI (version 4) cable
• keyboard - and optional a mouse
• Access to network (wired or wifi)
• Power - either an USB charger or cable to a PC (micro USB (version 3) or USB-C (version 4)

Make SD card a FAT32 partision, if reusing an old card

A new SD-card is fine as is, else

see http://qdosmsq.dunbar-it.co.uk/blog/2013/06/noobs-for-raspberry-pi/ for instruction to prepare any old or new SD-card

Add boot-files to SD card

Get the install zip-file from https://www.raspberrypi.org/downloads/noobs/

Then unpack NOOBS zip-file to the new disk (use the newest version), like for the network version

unzip NOOBS_lite_v3_5_1.zip -d /media/xxx/yyyy  or
unzip ~/Downloads/raspberry/NOOBS_lite_v3_5_1.zip  (if you are on the empty flash)

or for the full version

unzip NOOBS_v3_5_1.zip -d /media/xxx/yyyy  or
unzip ~/Downloads/raspberry/NOOBS_v3_5_1.zip  (if you are on the empty flash)

Reboot

• Insert SD card on Raspberry,
• Mount a heatsink - especially needed on version 4,
• Connect monitor, keyboard and power

That is all, Raspberry should boot on that, and take some time to prepare the SD-Card. Or see instructions on e.g.: https://www.raspberrypi.org/help/noobs-setup/

• Boot the raspberry and install the Raspberry Pi OS full (Debian).
• On the bottom of the screen select keyboard layout and language,

Settings

• Leave the pi password as is (for future reuse)
• Select language (prefer English - also for future reuse)
• select wifi access - if not using a cable.

Configure

Raspberry

use raspi-config, start a terminal:

sudo raspi-config

Using raspi-config

Expand Filesystem (if not OK already)
Set keyboard layout
Enable Camera
Set hostname (one word, no space)
Enable SSH
Disable Serial login
boot as a console with login
Update firmware
Set locale to "en_DK.UTF-8 UTF-8" (danish keyboard, but English language)

Update operating system

Ensure you have internet access, then

sudo apt-get update
sudo apt-get dist-upgrade
sudo reboot

Login

login as pi, password raspberry - password may have changed

Add a user called local, this leaves the pi user as is. This can save reformatting and reinstall when the Pi is to be reused.

add a user called local

sudo adduser local
sudo usermod -a --groups adm,cdrom,sudo,audio,video,plugdev,games,users,netdev,input,spi,gpio,i2c,dialout local 

switch user to local, and ensure groups are OK, and network is running

su - local
groups
ifconfig

Note the inet address.

Now it is possible to login (as local) from network.

Get access using hostname

You may change the hostname by changing the name in /etc/hostname. If you do so, then you should probably restart before the new hostname works.

Now from another PC on the local network

ping hostname.local

where "hostname" is replaced with the hostname in /etc/hostname.

Get filesystem on normal Linux PC

From another (Linux) PC, mount the raspberry filesystem

mkdir rpi  (where the filesystem will be mounted)
sshfs local@10.59.8.141: rpi    (replace IP number with inet address from above, or use sshfs local@hostnale.local: rpi)

Then in directory rpi the user files on the raspberry can be manipulated.

for other access, use (with IP address as found above, or IP replaced with hostname.local)

ssh -X local@10.59.8.141

Mobotware

• Not for Robobot
