CONFIG_FS_LITTLEFS_FC_MEM_POOL
¶
Enable flexible file cache sizes for littlefs
Type: bool
Help¶
littlefs requires a per-file buffer to cache data. For applications that use the default configuration parameters a memory slab is reserved to support up to FS_LITTLE_FS_NUM_FILES blocks of FS_LITTLEFS_CACHE_SIZE bytes.
When applications customize littlefs configurations and support different cache sizes for different partitions this preallocation is inadequate.
Select this feature to enable a memory pool allocator for littlefs file caches.
