config FS_NXFFS
bool "NXFFS file system"
default n
depends on !DISABLE_MOUNTPOINT

if FS_NXFFS
config NXFFS_ERASEDSTATE
bool "FLASH erased state"
default n
---help---
The erased state of FLASH.
This must have one of the values of 0xff or 0x00.
Default: 0xff.
config NXFFS_PACKTHRESHOLD
bool "Re-packing threshold"
default n
---help---

Default: 32.
config NXFFS_MAXNAMLEN
bool "Maximum file name length"
default n
---help---
The maximum size of an NXFFS file name.
Default: 255.
config NXFFS_TAILTHRESHOLD
bool "Tail threshold"
default n
---help---
clean-up can either mean
packing files together toward the end of the file or, if file are
deleted at the end of the file, clean up can simply mean erasing
the end of FLASH memory so that it can be re-used again. However,
doing this can also harm the life of the FLASH part because it can
mean that the tail end of the FLASH is re-used too often. This
threshold determines if/when it is worth erased the tail end of FLASH
and making it available for re-use (and possible over-wear).
Default: 8192.
