View source for How To Get Satellite CCRMA

by Edgar Berdahl, July 2011

== 1. Get The Parts ==

* Beagle Board (preferably the Beagle Board '''xM''', try [http://www.digikey.com DigiKey] or [http://www.mouser.com 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

* [http://www.arduino.cc/en/Main/ArduinoBoardNano Arduino Nano] from Gravitec

* 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 disk or partition, you could easily erase everything on it!'''
* First download the appropriate Satellite CCRMA SDHC card image from [http://ccrma.stanford.edu/~eberdahl/Satellite the main page] and uncompress it.
* Then run the <tt>df</tt> command in the Terminal and look at the output. For example, I get
<tt>OSX-Freshinstall:~ eberdahl$ df<br>
Filesystem    512-blocks      Used Available Capacity  iused   ifree %iused  Mounted on<br>
/dev/disk0s2   486717952 448570928  37635024    93% 56135364 4704378   92%   /<br>
devfs                394       394         0   100%      682       0  100%   /dev<br>
map -hosts             0         0         0   100%        0       0  100%   /net<br>
map auto_home          0         0         0   100%        0       0  100%   /home</tt>
* Connect the blank (micro) SD card to your Mac by plugging it in directly to a camera SD card reader or use a USB micro SDHC reader/writer.
* Run the <tt>df</tt> command again in the Terminal to determine that the SD card (in this case named '''Untitled''') corresponds to the partition /dev/disk'''2s1''' on the disk /dev/disk'''2'''. (Or for you, it might show up as /dev/disk'''3s1''' and /dev/disk'''3''' or /dev/disk'''4s1''' and /dev/disk'''4''', etc.)

* Unmount the partition by executing 
<tt>diskutil unmountDisk /dev/disk'''2s1'''</tt><br>
or similar.
* Write the image to the entire disk using the following
<tt>dd if=SatelliteCCRMA-xMRevC_Maverick.dd of=/dev/disk'''2'''</tt><br>
where you substitute the appropriate image name. This will take a while.

<br><br><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 

<tt>killall -INFO dd</tt> in Mac OS X, or

<tt>killall -USR1 dd </tt> 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/rdisk'''3''' instead, and/or try including the option <tt>bs=1m</tt>. 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.

For instance, when the procedure works for me, I see that almost all of the records are copied<br>
<tt>dd if=SatelliteCCRMA-xMRevC_Maverick.dd of=/dev/disk'''3'''<br>
7457+0 records in<br>
7456+1 records out<br>
7818186752 bytes transferred in 6604.225241 secs (1183816 bytes/sec)</tt>

== 3. Put Them All Together ==
Plug everything in, and you should be ready to go. Here it is with some speakers.
