1. Get The Parts

  • Beagle Board (preferably the Beagle Board xM, try DigiKey or Mouser)
  • 4GB SD/micro SDHC card - get a high-quality one from a brand like Kingston (Note: Don't try to use an 8GB card!)
  • One GT Max adjustable-length USB cable
  • Ethernet cable
  • 2.5A 5V switching power adaptor
  • Solderless breadboard
  • Only if you have the Beagle Board original: External Ethernet/USB hub such as the GWC Technology HE2440

2. Burn Image to the SD Card

Be very careful when carrying out this procedure! If you choose the wrong block device, you could easily erase everything on it!

  • Download the appropriate Satellite CCRMA SDHC card image from the main page and uncompress it.
  • Connect the blank (micro) SDHC card to your Mac by plugging it in directly to a camera SD card reader or use a USB micro SDHC reader/writer.
  • Open up the Terminal program, and find out which block device the (micro) SDHC card is connected to by running the df command. For instance, you might see it show up as something like /dev/disk3s1. If yours is named differently, then just substitute the correct name throughout the remainder of the instructions.
  • Unmount it by executing

diskutil unmountDisk /dev/disk3s1

  • Realize that the block device for the entire (micro) SDHC card is named /dev/disk3
  • Write the image to the entire (micro) SDHC card using the command

dd if=SatelliteCCRMA-xMRevC_Maverick.dd of=/dev/disk3

where you substitute the appropriate image name. This will take a while.

<Note from Wendy, July 2012> If you want to see how far along in the process you are, you can open another terminal window, and type

killall -INFO dd in Mac OS X, or

killall -USR1 dd in Linux.

Read the results in the terminal carefully. If the error is only that it was unable to write the last few blocks, that may be ok. We have padded the image with zeros at the end, so theoretically it shouldn't matter so much if some of the zeros at the end are missing.

If you have any further difficulties: try again, use e.g. of=/dev/rdisk3 instead, and/or try including the option bs=1m. This changes the block size of each write. No matter what, using a high-quality (micro) SDHC card can save you a lot of trouble later! For instance, we use the Kingston micro SDHC cards that come with the Beagle Board xM.

3. Put Them All Together

Plug everything in, and you should be ready to go. Here it is with some speakers.
