 Apple provides a copy of dd with recent releases of OS X (at least since 10.7, probably earlier).
 
+'''Finding the SD card descriptor:'''[[BR]]
  1. Insert the SD card
- 1. Run {{{diskutil list}}} to find device descriptor for SD card. Use this in place of {{{/dev/diskX}}} below.
+ 1. In a terminal run {{{diskutil list}}} to find device descriptor for SD card. Look for the SD card in the list of disks. On a MBP, the shows:

+'''Copying the .bin file:'''[[BR]]
  1. Unmount ('''not''' eject) the drive using this command:
 {{{
 diskutil unmountDisk /dev/diskX

-For each configuration file you wish to write:
- 1. Run:
+ 1. Run this command, replacing the last three arguments with the correct values:
 {{{
-dd bs=512 seek=N if=yourFile.bin of=/dev/diskX
+dd bs=512 seek=<N> if=<yourFile.bin> of=</dev/diskX>
 }}}
- 2. ''N'' (the argument to seek) depends on the target slot number; see the list above
+  1. ''<N>'': depends on the target slot number; see the list above
+  1. ''<yourFile.bin>'': the binary FPGA configuration file
+  1. ''</dev/diskX>'': device descriptor for the SD card
  1. If successful, dd should report:
 {{{
-blocks written

+9232444 bytes transferred in 8.503631 secs (1085706 bytes/sec)
 }}}
- 1. Repeat for additional config files if needed.
- 1. Some versions of OS X re-mount the FAT volume after each call to dd. Run {{{diskutil unmountDisk /dev/diskX}}} again to un-mount it.
+ 1. Repeat for additional .bin config files if needed.
+ 1. Eject the SD card in the Finder (if it's mounted).

+=== Windows ===
+
+A port of dd is available for Windows from XX. We have sucessfully tested verison 0.6b3 on Win 7 64-bit.
+
+Download dd.exe from the site above. Rename it win-dd.exe (to avoid conflicting with the dd.exe included with XPS) and place it somewhere in your Windows path.
