config FS_LITTLEFS
	bool "LITTLEFS File System"
	default n
	depends on !DISABLE_MOUNTPOINT
	---help---
		Build the LITTLEFS file system. https://github.com/littlefs-project/littlefs.

if FS_LITTLEFS
config FS_LITTLEFS_BLOCK_FACTOR
	int "LITTLEFS Block size multiple factor"
	default 4
	---help---
		Configure the cache size of the LITTLEFS file system with a multiple factor of the block size.
	
config FS_LITTLEFS_BLOCK_CYCLE
	int "LITTLEFS Block Cycle"
	default 200
	---help---
		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.
