config FS_SMARTFS
bool "SMART file system"
default n
depends on !DISABLE_MOUNTPOINT
select FS_READABLE
select FS_WRITABLE
---help---
Enable NuttX SMART Flash file system (SMARTFS) support.
if FS_SMARTFS
config SMARTFS_ERASEDSTATE
hex "FLASH erased state"
default 0xff
---help---
The erased state of FLASH.
This must have one of the values of 0xff or 0x00.
Default: 0xff.
config SMARTFS_MAXNAMLEN
int "Maximum file name length"
default 16
---help---
The maximum size of a SMARTFS file name at a given
directory level. Overall path name is not restricted
by this value, only individual segments in a path,
such as (assuming /usr is the mount point):
/usr/games/chess/player_stats/game1.xml
Default: 16.
config SMARTFS_MULTI_ROOT_DIRS
bool "Support multiple Root Directories / Mount Points"
default n
---help---
Enables support for multiple root directory entries
on the SMART FLASH. Multiple root directories means
the device can have multiple mount point in the VFS,
each with it's own unique directory structure under it.
When this option is enabled, instead of reporting the
SMART block devices as "/dev/mtdsmart0", they will be
reported as "/dev/mtdsmart0d1", "/dev/mtdsmart0d2", etc.
The number of root entries actually created is set
during the "mksmartfs" command when the device is
initialized.
Default: y.
config SMARTFS_ALIGNED_ACCESS
bool "Ensure 16 and 32 bit accesses are alined"
default n
---help---
Performs little endian byte accesses to 16 and 32 values
within the directory list to ensure processors that can't
handle un-aligned accesses don't bomb out. Default should
probably by 'Y', but set to 'N' in case any existing Big
Endian instances of SmartFS exist that already have
directories with data stored in big endian mode.
