FTL_FORMAT(1) General Commands Manual FTL_FORMAT(1)
ftl_format - Flash Translation Layer formatting utility
ftl_format [-q] [-i] [-s spare] [-r reserve] [-b bootsize] device
Ftl_format creates a Flash Translation Layer partition on a flash mem-
ory device. It needs to access the flash partition's raw character-
mode device (such as /dev/mem0c0c).
This is actually a low-level format operation, required before access-
ing a memory device via the FTL block device driver. Once a partition
is prepared with ftl_format, a filesystem should be created in a sepa-
rate step. Filesystem commands should access the device via the FTL
device file (such as /dev/ftl0).
Optionally, ftl_format can reserve a region at the beginning of the
flash card address space for a boot image (or any other purpose). The
boot area is not part of the FTL partition, and can only be accessed
via the raw memory device.
On Intel Series 100 flash cards, the first flash block is used to store
the card's configuration information structures. If no boot area is
specified on the command line, ftl_format will automatically create one
to span the first block.
-q Quiet mode: don't print formatting statistics.
-i Interactive: confirm before beginning the format.
Reserve the specified number of erase blocks as spares. The
default is 1. A read-write partition requires at least one
Reserve the specified percentage of the total space on the
device to improve write efficiency. The default is 5%. Reserv-
ing less space increases the frequency of flash erase operations
to reclaim free blocks.
Requests that a portion of the flash card be reserved for a boot
image. The size will be rounded up to an integral number of
