Hi Graeme, I can’t tell you how much time your little script has saved me. I have also posted a link to it in the Meld embedded Linux Texas Instruments discussion group at

http://meld.mvista.com

We’d be very happy if you joined the discussion.

thanks!

Thanks for your script. Simple but efficient… and exactly what I was searching for.

I made few customizations:
– Detect if drive has been given on command line. If fail, then usage is displayed.

– I had an issue with your script by having Nautilus file browser (I’m using Ubuntu Gnome) starting automatically after FAT32 part.
Don’t know why! May be because of my SD card that was containing some pictures before.
Therefore, I added some umount before each mkfs/mke2fs to solve that issue.

dd if=/dev/zero of=$DRIVE bs=1024 count=1024

SIZE=`fdisk -l $DRIVE | grep Disk | awk ‘{print $5}’`

echo DISK SIZE – $SIZE bytes

CYLINDERS=`echo $SIZE/255/63/512 | bc`

echo CYLINDERS – $CYLINDERS

if [ -b ${DRIVE}1 ]; then
umount -l ${DRIVE}1
mkfs.vfat -F 32 -n “boot” ${DRIVE}1
else
if [ -b ${DRIVE}p1 ]; then
umount -l ${DRIVE}p1
mkfs.vfat -F 32 -n “boot” ${DRIVE}p1
else
echo “Cant find boot partition in /dev”
fi
fi

if [ -b ${DRIVE}2 ]; then
umount -l ${DRIVE}2
mke2fs -j -L “rootfs” ${DRIVE}2
else
if [ -b ${DRIVE}p2 ]; then
umount -l ${DRIVE}p2
mke2fs -j -L “rootfs” ${DRIVE}p2
else
