bmaptool

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

• Create a blockmap 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}}
