NAME¶
lpmake - Android dynamic partition tools
DESCRIPTION¶
lpmake - command-line tool for creating Android Logical Partition images.
Usage:¶
- lpmake [options]
Required options:¶
- -d,--device-size=[SIZE|auto]
- Size of the block device for logical partitions. Can be set to auto to automatically calculate the minimum size, the sum of partition sizes plus metadata-size times the number of partitions.
- -m,--metadata-size=SIZE
- Maximum size to reserve for partition metadata.
- -s,--metadata-slots=COUNT
- Number of slots to store metadata copies.
- -p,--partition=DATA
- Add a partition given the data, see below.
- -o,--output=FILE
- Output file.
Optional:¶
- -b,--block-size=SIZE
- Physical block size, defaults to 4096.
- -a,--alignment=N
- Optimal partition alignment in bytes.
- -O,--alignment-offset=N
- Alignment offset in bytes to device parent.
- -S,--sparse
- Output a sparse image for fastboot.
- -i,--image=PARTITION=FILE
- If building a sparse image for fastboot, include the given file (or sparse file) as initial data for the named partition.
- -g,--group=GROUP:SIZE
- Define a named partition group with the given maximum size.
- -D,--device=DATA
- Add a block device that the super partition spans over. If specified, then -d/--device-size and alignments must not be specified. The format for DATA is listed below.
- -n,--super-name=NAME
- Specify the name of the block device that will house the super partition.
- -x,--auto-slot-suffixing
- Mark the block device and partition names needing slot suffixes before being used.
- -F,--force-full-image
- Force a full image to be written even if no partition images were specified. Normally, this would produce a minimal super_empty.img which cannot be flashed; force-full-image will produce a flashable image.
- --virtual-ab
- Add the VIRTUAL_AB_DEVICE flag to the metadata header. Note that the resulting super.img will require a liblp capable of parsing a v1.2 header.
Partition data format:¶
- <name>:<attributes>:<size>[:group] Attrs must be 'none' or 'readonly'.
Device data format:¶
- <partition_name>:<size>[:<alignment>:<alignment_offset>] The partition name is the basename of the /dev/block/by-name/ path of the block device. The size is the device size in bytes. The alignment and alignment offset parameters are the same as -a/--alignment and -O/--alignment-offset.
