bmaptool

Create or copy block maps intelligently (designed to be faster than cp or dd). More information: https://source.tizen.org/documentation/reference/bmaptool.

• [o]utput a blockmap file from image file:

bmaptool create -o blockmap.bmap source.img

• Copy an image file into sdb:

bmaptool copy --bmap blockmap.bmap source.img /dev/sdb

• Copy a compressed image file into sdb:

bmaptool copy --bmap blockmap.bmap source.img.gz /dev/sdb

• Copy an image file into sdb without using a blockmap:

bmaptool copy --nobmap source.img /dev/sdb
