Today my [Raspberry Pi][pi] arrived and I quickly got it up and running.
|
||||||
|
|
||||||

Want to see some pictures?

Now that you've seen one in action, here is some info how I successfully setup
|
||||||
|
the Raspberry Pi.

||||||

## Prepare for boot
|
||||||
|
|
||||||
|
Before I could use my Raspberry I had to prepare my tools:
|
||||||
|
|
||||||
|
* Get a mini-usb cable (the one from my smartphone works perfect)
|
||||||
|
* Get a HDMI cable (got one for ~6€ at Amazon)
|
||||||
|
* Get a SD Card (again: Amazon, a Transcend 16 GB thing)
|
||||||
|
* A USB keyboard (and mouse). Got that.
|
||||||
|
* A LAN cable, I have several.
|
||||||
|
|
||||||
|
Next I needed an image to boot. I use the [archlinux image][alarm]. Get it from
|
||||||
|
the [download section][downloads].
|
||||||
|
|
||||||
|
Copying the image to the SD Card was easy:
|
||||||
|
|
||||||
|
dd bs=1M if=archlinuxarm-29-04-2012.img of=/dev/mmcblk0
|
||||||
|
|
||||||
|
The image is prepared for a 2 GB card, so I had to expand the partitions. I
|
||||||
|
failed with `parted`, re-did the `dd`-commando and used gParted instead (see
|
||||||
|
[the wiki][resize] for instructions)
|
||||||
|
|
||||||
|
Putting the SD Card in the slot, adding the cables and it booted up! Yey!
|
||||||
|
I even got video output, atleast on my TV.
|
||||||
|
|
||||||
|
Not so on the other display. It always switched to standby without any chance
|
||||||
|
to get an output.
|
||||||
|
|
||||||
|
So again back to the laptop and edit `/boot/config.txt` (Thanks,
|
||||||
|
[@bl2nk](http://twitter.com/bl2nk), [more info about the file][config.txt]):
|
||||||
|
|
||||||
|
# Force HDMI (including audio output)
|
||||||
|
hdmi_drive=2
|
||||||
|
|
||||||
|
# Use "safe mode" settings to try to boot with maximum hdmi compatibility.
|
||||||
|
# This does:
|
||||||
|
# hdmi_force_hotplug=1
|
||||||
|
# config_hdmi_boost=4
|
||||||
|
# hdmi_group=1
|
||||||
|
# hdmi_mode=1
|
||||||
|
# disable_overscan=0
|
||||||
|
hdmi_safe=1
|
||||||
|
|
||||||
|
Self-explaining, right?
|
||||||
|
|
||||||
|
Ok, so it boots up again, now with video output on the display here.
|
||||||
|
To bad there's no LAN port in my room.
|
||||||
|
|
||||||
|
## Network forwarding
|
||||||
|
|
||||||
|
This has nothing to do with the Raspberry Pi itself but with simple network forwarding.
|
||||||
|
I connected the Pi via LAN to my laptop which got it's internet connection via WLAN.
|
||||||
|
|
||||||
|
On my laptop I did these things to forward:
|
||||||
|
|
||||||
|
ip addr del 192.168.10.1/24 dev eth0
|
||||||
|
|
||||||
|
sysctl net.ipv4.ip_forward=1
|
||||||
|
|
||||||
|
iptables -A FORWARD -o wlan0 -i eth0 -s 192.168.1.0/24 -m conntrack --ctstate NEW -j ACCEPT
|
||||||
|
iptables -A FORWARD -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
|
||||||
|
iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
|
||||||
|
|
||||||
|
On the Pi:
|
||||||
|
|
||||||
|
ip addr del 192.168.10.24/24 dev eth0
|
||||||
|
ip route add default via 192.168.10.1
|
||||||
|
echo "nameserver 8.8.8.8" > /etc/resolv.conf'
|
||||||
|
|
||||||
|
Now it works like a charm (I added this config to `rc.conf` so it works after boot).
|
||||||
|
|
||||||
|
## More installing on the Pi
|
||||||
|
|
||||||
|
All the previous steps were done as the root user. But for daily use we want an own user:
|
||||||
|
|
||||||
|
adduser
|
||||||
|
|
||||||
|
(See the [arch wiki](https://wiki.archlinux.org/index.php/Beginners%27_Guide#Adding_a_User) for more info on that)
|
||||||
|
|
||||||
|
Now switch the user (or just re-login):
|
||||||
|
|
||||||
|
su username
|
||||||
|
|
||||||
|
### Audio
|
||||||
|
|
||||||
|
To enable sound via alsa I installed the required libs and load the module:
|
||||||
|
|
||||||
|
pacman -S alsa-lib alsa-utils
|
||||||
|
modprobe snd-bcm2835
|
||||||
|
|
||||||
|
Then added `snd-bcm2835` to the MODULES section in `rc.conf` so it gets loaded after boot.
|
||||||
|
|
||||||
|
### GUI / X-Server
|
||||||
|
|
||||||
|
I know, I know: Hardcore Linux users don't need it, but it gets quite handy, so
|
||||||
|
I installed a GUI environment:
|
||||||
|
|
||||||
|
# X server and i3 window manager
|
||||||
|
pacman -S xorg-server xorg-xinit xorg-server-utils xf86-video-fbdev i3-wm i3lock i3status
|
||||||
|
echo 'exec i3' > ~/.xinitrc
|
||||||
|
# Terminal emulator
|
||||||
|
pacman -S rxvt-unicode urxvt-url-select
|
||||||
|
# Oh yeah, some fonts would be great
|
||||||
|
pacman -S ttf-bitstream-vera ttf-dejavu ttf-freefont ttf-liberation terminus-font
|
||||||
|
|
||||||
|
Everything in place, let's start X:
|
||||||
|
|
||||||
|
startx
|
||||||
|
|
||||||
|
I won't show my basic i3 and i3status configuration here. [Feel free to ask][twitter]
|
||||||
|
if you've got any questions.
|
||||||
|
|
||||||
|
What's needed now? Right, everything for daily usage:
|
||||||
|
|
||||||
|
pacman -S git mplayer tree scrot feh
|
||||||
|
|
||||||
|
Ok, what's left? A [browser][luakit].
|
||||||
|
|
||||||
|
pacman -S luakit
|
||||||
|
|
||||||
|
That's it for now. The basic setup of my Pi is done.
|
||||||
|
|
||||||
|
shutdown -h now
|
||||||
|
|
||||||
|
## What's next?
|
||||||
|
|
||||||
|
Oh, that's easy.
|
||||||
|
|
||||||
|
* I need to check out [rpi-update][], for updating the firmware.
|
||||||
|
* Get video playing done right. I did not fully test it, but the video in the
|
||||||
|
second image above was quiet slow.
|
||||||
|
* I want [xbmc][] to run on my Raspberry Pi, because that's what I bought it for:
|
||||||
|
it should become my media computer in the living room.
