This is a GUI interface program, which can be used in windows in order to read and write images from SD card. It can also be used to write boot images, on a USB drive. This program can save an SD card image in .img format, so that one does not have to repeat the image building process all over again, such as partitioning SD card, coping root files.
Boot images and SD card images are used on the beagle board in order to run demos. Storing images in an SD card is handy. It enables an user to switch demos, by switching the SD card with another with a different image.
