Subject: [cip-dev] [[PATCH v2]] bmap: generate bmap for wic images
Date: Wed,  5 Jun 2019 16:17:09 +0900	[thread overview]
Message-ID: <20190605071709.12908-2-daniel.sangorrin@toshiba.co.jp> (raw)
In-Reply-To: <20190605071709.12908-1-daniel.sangorrin@toshiba.co.jp>

bmap shortens the time required to flash an image.
This can be useful when you need a fixed-size image, for
example to update partitions with swupdate.

Example usage:
sudo bmaptool copy --bmap \
build/tmp/deploy/images/iwg20m/cip-core-image-cip-core-iwg20m.wic.img.bmap \
build/tmp/deploy/images/iwg20m/cip-core-image-cip-core-iwg20m.wic.img \
/dev/sdf
