| | 1 | == Writing SD Cards: Linux == |
| | 2 | Every Linux distro should include dd. Run {{{which dd}}} to confirm you have it installed. |

| | 4 | '''Finding the SD card descriptor:'''[[BR]] |
| | 5 | 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: |
| | 7 | {{{ |
| | 8 | }}} |
| | 9 | 2. In this example, the SD card device descriptor is {{{/dev/disk1}}}. The actual descriptor will differ on other machines with different disk configurations, but should take the form {{{/dev/diskX}}}. |
| | 10 | |
| | 11 | '''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 | }}} |
| | 16 | 1. Run this command, replacing the last three arguments with the correct values: |
| | 17 | {{{ |
| | 18 | dd bs=512 seek=<N> if=<yourFile.bin> of=</dev/diskX> |
| | 19 | }}} |
| | 20 | 1. ''<N>'': depends on the target slot number; use (131072 + slotNum*32768). More details [wiki:..#Copying.binFilesSDCards here]. |
| | 21 | 1. ''<yourFile.bin>'': the binary FPGA configuration file |
| | 22 | 1. ''</dev/diskX>'': device descriptor for the SD card |
| | 23 | 1. If successful, dd should report the following (the time/throughput values will differ): |
| | 24 | {{{ |
| | 25 | 18032+1 records in |
| | 26 | 18032+1 records out |
| | 27 | 9232444 bytes transferred in 8.503631 secs (1085706 bytes/sec) |
| | 28 | }}} |
| | 29 | 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). |
