| The most typical use of an SD Card in embedded applications is as a removable storage device (disk) that can be easily taken from the embedded target board. In such contexts, the SD Card installed to the embedded target board is typically already formatted with an MS-DOS file system. The Linux kernel must be specially configured to allow mounting the MS-DOS file system. See part 2 in section 2.1 for details. The mount utility is also needed.

| + | In order to use an SD Card with Linux we need to prepare it by formatting it in the correct format. | ||
| + | |||
| + | This section of instructions requires you to correctly identify the SD Card and format the card. If you select the wrong drive you may cause irreversible damage to you Host PC. | ||
| + | |||
| + | To format the SD Card, follow the commands below. The example code in this section assumes that the SD Card device is reported to be /dev/sdb. Ensure that you change these commands to use your device. | ||
