Download Image
1. Download the latest Raspbian release (Wheezy) from http://www.raspberrypi.org/downloads (e.g. 2013-05-25-wheezy-raspbian.zip).
2. Check that the hash of the downloaded file matches the one on the download site.
$ sha1sum 2013-05-25-wheezy-raspbian.zip 131f2810b1871a032dd6d1482dfba10964b43bd2 2013-05-25-wheezy-raspbian.zip
Write Image to SD Card
3. Extract the SD card image file from the archive.
$ unzip 2013-05-25-wheezy-raspbian.zip
4. Write the image to the SD card.
$ sudo dd bs=4M if=2013-05-25-wheezy-raspbian.img of=/dev/sdc
where /dev/sdc is the path to the SD card device.
IMPORTANT: The path varies; using the wrong path would cause the wrong disk to be overwritten.
Resize Root Partition on SD Card
5. Run parted on /dev/sdc.
$ sudo parted /dev/sdc
6. Print the partition table.
(parted) unit chs (parted) print Model: Generic STORAGE DEVICE (scsi) Disk /dev/sdc: 482,18,47 Sector size (logical/physical): 512B/512B BIOS cylinder,head,sector geometry: 482,255,63. Each cylinder is 8225kB. Partition Table: msdos Number Start End Type File system Flags 1 0,130,2 7,165,29 primary fat16 lba 2 7,165,30 235,214,42 primary ext4
7. Remove the existing root partition.
(parted) rm 2
8. Re-create the partition, filling the entire disk.
(parted) mkpart primary 7,165,30 482,18,47 (parted) quit
where 7,165,30 is the starting chs (cylinder, head, sector) number of the original (deleted) partition, and 482,18,47 is the ending chs number of the disk. The information is available in the original partition table.
9. Check and repair the root partition.
$ sudo e2fsck -f /dev/sdc2
10. Resize the root partition.
$ sudo resize2fs /dev/sdc2
Login to Raspberry Pi
11. Insert the SD card into the Raspberry Pi and switch it on.
12. Access the Raspberry Pi remotely using SSH.
$ ssh pi@192.168.1.2
where 192.168.1.2 is the IP address assigned to the device. The default username is pi, and the password is raspberry.
