Raspberry Pi Media Centre – Solving the Rainbow Screen of Death

Raspberry Pi Media Centre – Solving the Rainbow Screen of Death

I decided to break the seal on my Pi and install Raspbmc to use it as media centre. Raspbmc is¬† Linux distribution that brings XBMC (open source (GPL) software media player and entertainment hub) to the Raspberry Pi. I have an Apple TV and a PS3 that I currently use for streaming video to my TV. The PS3 doesn’t handle large files well because it doesn’t have wireless N. It also doesn’t support MKV files. I have used an app call Air Parrot to mirror my laptop screen on my Apple TV to solve the problem of streaming larges Hi-Def MKVs. This setup is not convenient. Enter the Raspberry Pi.

This is the list of hardware I acquired for a media centre. Not all of these items are required to get up and running.

  1. Patriot 32GB LX Series Class 10 SDHC
  2. Axpertec, Inc. Edimax 150 Mbps Wireless 11n Nano Size USB Adapter
  3. Belkin Ultra-Slim Series 4-Port USB 2.0 Hub (F4U040v)
  4. Logitech Wireless Touch Keyboard K400 with Built-In Multi-Touch Touchpad
  5. Raspberry Pi Power Adapter, Raspberry Pi, AC-DC Micro USB 5.25 V – 1A (1000mA)
  6. Raspberry Pi Enclosure
  7. Raspberry Pi

If you’re going to buy any peripherals make sure it’s compatible an on this list: http://elinux.org/RPi_VerifiedPeripherals

This is the process I initially used for installing Raspbmc with OSX: http://www.raspbmc.com/wiki/user/os-x-linux-installation/

When I booted up my Pi for the first time I was met with disappointment as it was a stuck in a infinite boot loop featuring the rainbow square of death:

At first I thought a had a bad image / SD card. I tried reformatting, reinstalling Raspbmc and alternate SD cards with the same result.

I also tried installing Raspbmc via NOOBS (offline and network install) with no luck: http://www.raspberrypi.org/downloads

I then checked the actual voltage on the Raspberry Pi circuit board. There are two test points labelled TP1 and TP2.

With a multimeter which is set to the range 20 volts DC (or 20v =), you should see a voltage between 4.75 and 5.25 volts. I was getting a reading of 4.20 volts, indicating that I had a problem with my power supply or power cable.. When I contacting my PSU vendor they indicated they had recently got a bad shipment of power cables. When I replaced the cable with a USB to Micro USB from my Blackberry Playbook, the PI booted into NOOBs and displayed a list of operating systems to install. Once I installed Raspbmc, it was really easy to configure the WiFi dongle and starting streaming files from my NAS.

Streaming HD video over WiFi to my #RaspberyPi running #Raspbmc with no buffering or stuttering at all.

I find the Raspbmc menu system to be a little slow. There are some tweaks you can do to make it perform better like :

  1. Running Raspbmc off a USB3 Memory Stick instead of SD card
  2. Disabling thumbnail extraction in the library
  3. Changing the default skin to Quartz
  4. Change resolution to 720p if you don’t watch 1080p videos
  5. Overclock the Pi
