20 - littlefs is a block-based filesystem. The disk is divided into an array of
23 - Block pointers are stored in 32 bits, with the special value `0xffffffff`
26 - In addition to the logical block size (which usually matches the erase
31 - By default, all values in littlefs are stored in little-endian byte order.
49 The high-level layout of a metadata block is fairly simple:
