This article shows how to create a bootable microSD card for the [[AXEL_ULite_and_SBC_Lynx_Embedded_Linux_Kit_(XUELK)|XUELK]] kit by using a simple bash script. The procedure has been tested on a Linux PC running Ubuntu LTS (>=12 .04) distribution with
*a 16 GB microSD card [1]
*the binary files delivered along with the [[AXEL_ULite_and_SBC_Lynx_Embedded_Linux_Kit_(XUELK)#Downloadable_binary_images|XUELK 1.1.3]].
CYLINDERS=`echo $SIZE/255/63/512 | bc`
# check if we're running an old (e.g. 2.20.x) or new (e.g. 2.24.x) sfdisk
sfdisk --help | grep -- -H
if [ "$?" -eq "0" ]
then
{
echo 10,1380,0x0c,*
echo 1390,,83,-
} | sfdisk -D -H 255 -S 63 -C $CYLINDERS $DRIVE
else

echo "[Making filesystems...]"

[1] In case you have a different size, you'll need to change the <code>sfdisk</code> parameters accordingly.
