Raspberry Pi Setup

Raspbian Linux Setup

1. Download Raspbian 'Wheezy' SD card image This guide was made using 18th September 2012 release.
2. Copy SD card image on SD card using Linux tool "dd" for any other OS see Raspberry Pi tutorial
   • Insert SD card $ df -h to view mounted partition, make note of SD card device name, for me this was 'sdb'
   • Unmount SD card $ umount /dev/sdb1 you will need to change sdb to match your SD card drive. If the card has more than one partition un mount that also $ umount /dev/sdb2
   • Write the .img to the card $ sudo dd bs=4M if=~/Downloads/2012-09-18-wheezy-raspbian.img of=/dev/sdb again you will need to replace sdb with your SD card device name and modify the location and name of the image as need.
3. Put SD card into Pi and connect network and power
4. Find the IP address of the Pi and SSH to it $ SSH [email protected], default password is 'raspberry'
5. Once successfully logged in run Raspbian setup $ sudo raspi-config
   • Select Expand root partition to fill SD card finish and reboot
   • One rebooted restart SSH connection and run $ sudo raspi-config again
   • Check for updates, reboot and run $ sudo raspi-config again
   • Change password for user Pi to something of your choice, make it secure it will be storing your home energy data!
   • If you plan to run the Pi as a headless dataloggin emoncms server as we do then select memory-split and choose the first setting a 240/16 split, the gives the CPU more memory at the expense of graphics which we're not using
   • We also recommend selecting boot behaviour and disabling booting straight into a desktop since this increases boot time and wastes system resources. If required a desktop can be loaded with $ startx.
   • Set locale and timezone as required
   • Finish and reboot, remember to use your new password when SSH'ing back in!
