moves SCSI disk images from and to a SCSI2SD SDcard.
The SCSI2SD hardware implements up to 4 SCSI hard disks on a single SDcard, see www.codesrc.com
This allows to operate vintage computer hardware without physical SCSI drives.
The partition layout of a SDcard is defined with the tool "scsi2sd-util", and kept as an XML file.
"img2sd" reads the XML config file, then allows to read/write/verify the SDcard partition against binary file images.
This could also be done with "dd" command, but then block offset and sizes must be calculated manually.
Compile tested under Ubuntu. The "libxml" package is needed. Install with
sudo apt-get install libxml2-dev
See makefile for more info.
The build-in help should say all:

Command line summary:
img2sd --help --verbose --device <device_filename> --xml <config_filename>
--read <target_id> <image_file> --write <target_id> <image_file>
--compare <target_id> <image_file>
--writecompare <target_id> <image_file>
-? | --help
Print help
-v | --verbose
Verbose output
-d | --device <device_filename>
Raw SDCard device, without "/dev".
To check: plug in SDcard, then "dmesg | tail"
Simple example: -d sdb
Use "/dev/sdb" as interface to SDcard.
-x | --xml <config_filename>
Path to mandatory SCSI2SD geometry config file (XML)
Simple example: -x 4xRD54_rev471.xml
The XML file must be generated with "scsi2sd-util".
-r | --read <target_id> <image_file>
Read disk image from SDcard partition.
Simple example: -r 3,rsxdata.img
Read partition with SCSI ID #3 and save it as file "rsxdata.img".
-w | --write <target_id> <image_file>
Write disk image into SDcard partition. Size must fit!
Simple example: -w 0,rt1157.rd54
Copy the disk image file "rt1157.rd54" onto drive #0 partition
Offset and size on SDcard is taken from XML config file.
-c | --compare <target_id> <image_file>
Compare disk image file with SDcard partition.
-wc | --writecompare <target_id> <image_file>
First write, then compare
