Hi I want to know clearly the maximam file system size for YAFFS2 can handle. In file ysffs_guts.h, there're ysffs_Tags structure: typedef struct { unsigned chunkId:20; unsigned serialNumber:2; unsigned byteCount:10; unsigned objectId:18; unsigned ecc:12; unsigned unusedStuff:2; } yaffs_Tags; I can calculate the maximum file system size YAFFS2 can handle by following algorithm: (2^20)*(2^18)*(2kb)= 2^49B //Chunk size is 2kb Am I right? Appreciate for your reply! Thanks.
