CONFIG_FS_LITTLEFS_LOOKAHEAD_SIZE¶
Size of lookahead buffer in bytes
Type: int
Help¶
A larger lookahead buffer increases the number of blocks found
during an allocation pass. The lookahead buffer is stored as a
compact bitmap, so each byte of RAM can track 8 blocks. Must
be a multiple of 8.
Direct dependencies¶
FILE_SYSTEM_LITTLEFS && FILE_SYSTEM
(Includes any dependencies from ifs and menus.)
Default¶
32
