Configure the cache size of the LITTLEFS file system with a multiple factor of the block size.

Configure the block cycle of the LITTLEFS file system.

config FS_LITTLEFS_NAME_MAX
|
|
int "LITTLEFS LFS_NAME_MAX"
|
|
default NAME_MAX
|
|
---help---
|
|
Configure LFS_NAME_MAX value for LITTLEFS file systems.
|
|
|
|
Note: Using a larger value for this configuration makes the lfs_info
|
|
structure larger and thus increases the stack usage.
|
|
|
|
Note: To mount a LITTLEFS filesystem, this configuration should
|
|
equal to or larger than the corresponding on-disk parameter.
|
|
|
|
Note: Many of tools to generate LITTLEFS images use 255 for
|
|
this by default.
|
|
|
|
Note: NuttX releases prior to 10.4.0 (exclusive) uses 255
|
|
for this. If you need to mount LITTLEFS filesystems used by
|
|
previous versions of NuttX, it's safer to use 255.
|
|
|
|
config FS_LITTLEFS_FILE_MAX
|
|
int "LITTLEFS LFS_FILE_MAX"
|
|
default 2147483647
|
|
---help---
|
|
Configure LFS_FILE_MAX value for LITTLEFS file systems.
|
|
|
|
Note: To mount a LITTLEFS filesystem, this configuration should
|
|
equal to or larger than the corresponding on-disk parameter.
|
|
|
|
Note: Many of tools to generate LITTLEFS images use 2147483647
|
|
for this by default.

|
config FS_LITTLEFS_ATTR_MAX
|
|
int "LITTLEFS LFS_ATTR_MAX"
|
|
default 1022
|
|
---help---
|
|
Configure LFS_ATTR_MAX value for LITTLEFS file systems.
|
|
|
|
Note: To mount a LITTLEFS filesystem, this configuration should
|
|
equal to or larger than the corresponding on-disk parameter.
|
|
|
|
Note: because NuttX's LITTLEFS driver does never use custom attributes,
|
|
the value of this configuration doesn't matter much. The default value
|
|
here is chosen to be compatible with filesystems created by external
|
|
tools. Unlike LFS_NAME_MAX, a large LFS_ATTR_MAX value doesn't
|
|
have any runtime overhead, at least with the implementation as of
|
|
writing this.
|
|
|
|
Note: Many of tools to generate LITTLEFS images use 1022
|
|
for this by default.
