Hello, I am trying to make a SD Card image without using a neutrino environment where I have fdisk / mount, etc.

I would like to create the same image with some sequence where dd creates the image file (say 64 meg) and then initializes it in a similar manner as below.

My SDCard image script does the following with a SD card mounted in a USB reader/writer for the card.

umount /fs/usb0

umount /fs/usb1

umount /fs/usb2

umount /fs/usb3

fdisk /dev/umass0 delete

fdisk /dev/umass0 add

echo removing partitions

fdisk /dev/umass0 delete -a

echo creating partions

fdisk /dev/umass0 add -c 0,15 -s 1 -t 79

fdisk /dev/umass0 add -c 16,31 -s 2 -t 77

mount -e /dev/umass0

fdisk /dev/umass0 show

echo initializing the boot partition

dinit -q -h -f $ifsSrc  /dev/umass0t79

dinit -q -h /dev/umass0t77

echo mounting partitions

mount -tqnx4 /dev/umass0t77 /var/tmp/opt

mount -tqnx4 /dev/umass0t79 /var/tmp/root
