In case you've been living under a rock, the Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard.
I'll bring along some of my Geekology Raspberry Pi's, the USB TV tuner and whatever else I can cram into my luggage.
Drop by to have a look.
- Thomas Sprinkmeier (28.26 incl. Camera, RaspBMC (with USB tuner) and NOOBS)
- Daniel Bryan
- Jessica Smith (depending on timing of BoF)
- Phil Smith (possibly)
- Daryl Tester (intrigued, yet suspicious)
- Adam Ashley might bring a pi, or some of the other little toys they let me play with at work.
- Brett Downing
- Steven Ellis a strong maybe
- Chris Willoughby - possibly
- Gordon Stanton - (maybe with a Quad Core ARM dev board)
- Msquared (I have a spare Pi setup to bring)
- Karl-Johan Karlsson, with a Pi-Lite red LED array
- I've got some Hardware Info
- NOOBS download page. The simplest way to boot your Pi.
- Scratch. Sadly the latest version doesn't run on the Pi, but it's a great intro to programming including GPIO.
- Wireless doorbell -> email project. One of the Geeklings made this, with a little help...
- Arduino + Pi = very simple and robust IO.
Quick-and-dirty instructions on how to make your own minimal RasPi SD-card using buildroot
$ git clone http://git.buildroot.net/git/buildroot.git
Set up the Raspberry Pi defaults and (optionally) modify (change defalt hostname, add ssh, etc.):
$ make help $ make raspberrypi_defconfig $ make xconfig
Build (this step takes a while):
You now have the output files:
$ ls output/images/ -R output/images/: rootfs.tar rpi-firmware zImage output/images/rpi-firmware: bootcode.bin cmdline.txt config.txt fixup.dat start.elf
Partition and format an SD card:
$ sudo sudo fdisk -l /dev/mmcblk0 Disk /dev/mmcblk0: 31.9 GB, 31914983424 bytes 4 heads, 16 sectors/track, 973968 cylinders, total 62333952 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000c475a Device Boot Start End Blocks Id System /dev/mmcblk0p1 * 2048 2832031 1414992 e W95 FAT16 (LBA) /dev/mmcblk0p2 2832384 62328831 29748224 83 Linux
You can use gparted or the usual commandline tools to create/format/label these partitions.
Populate the /root partition:
$ sudo tar --extract --verbose --preserve --file ~sprinkmeier/GIT/buildroot/output/images/rootfs.tar --directory /media/buildROOT/
The tarball MUST be extracted as root to allow the proper ownership/permissions to be set up.
Copy the boot files into the FAT partition:
$ ls /media/EF65-BDC7/ bootcode.bin cmdline.txt config.txt fixup.dat start.elf zImage $ ls /media/buildROOT/ bin etc lib linuxrc media opt root sbin tmp var dev home lib32 lost+found mnt proc run sys usr
As you can see you only need a few MB:
$ df /dev/mmcblk0p2 28G 179M 27G 1% /media/buildROOT /dev/mmcblk0p1 1.4G 5.3M 1.4G 1% /media/EF65-BDC7
The SD card should now be ready to boot.
