    44'''Finding the SD card descriptor:'''[[BR]]
    55 1. Insert the SD card
    6  1. In a terminal run {{{fdisk -l}}}. Depending on your system, you may need to run this as root ({{{sudo fdisk -l}}}). Look for the SD card in the list of disks. On an Ubuntu 12.04 system with one hard drive, the output is:
     6 1. In a terminal run {{{fdisk -l}}}. Depending on your system, you may need to run this as root ({{{sudo fdisk -l}}}).
     7 1. Find the SD card in the list of disks. The descriptor will have the form {{{/dev/<something>}}}
     8  1. On our test system (Ubuntu 12.04, PC with one hard drive), the output is:

     38  2. In this output, the first disk is the computer's hard drive. The second disk is the SD card (notice the capacity of approx 2GB, with 1 32MB FAT partition).

    1141'''Copying the .bin file:'''[[BR]]
    12  1. Unmount ('''not''' eject) the drive using this command (replacing {{{X}}} with your actual SD descriptor):
    13 {{{
    14 diskutil unmountDisk /dev/diskX
    15 }}}
    1642 1. Run this command, replacing the last three arguments with the correct values:
    1743{{{
    18 dd bs=512 seek=<N> if=<yourFile.bin> of=</dev/diskX>
     44dd bs=512 seek=<N> if=<yourFile.bin> of=</dev/someDevice>
    1945}}}
    2046  1. ''<N>'': depends on the target slot number; use (131072 + slotNum*32768). More details [wiki:..#Copying.binFilesSDCards here].
    2147  1. ''<yourFile.bin>'': the binary FPGA configuration file
    22   1. ''</dev/diskX>'': device descriptor for the SD card
     48  1. ''</dev/someDevice>'': device descriptor for the SD card
    2349 1. If successful, dd should report the following (the time/throughput values will differ):
    2450{{{

    2954 1. Repeat for additional .bin config files in additional slots if needed.
    30  1. Eject the SD card in the Finder (if it's mounted).
