Please insert a SD card in the card reader on your Linux host PC
1) Check device node of your SD card by command below.
$cat /proc/partitions (for example, mine is /dev/sdd as below)
Create EXT3 partition for SD card

Type the following parameters (each followed by ):
d [delete the previous partition]
n [create a new partition]

1 [the first partition]
20480 [20480x512bytes=10MB, which leaves enough space for the kernel, the
boot loader and its configuration data]
[using the default value will create a partition that spans to the last
sector of the medium]
w [ this writes the partition table to the medium and fdisk exits]

$sudo mkfs.ext3 /dev/sdd1
