That is expected behaviour, the size of an ext[23] filesystem is stored in its superblock. > I can make it have additional blocks, but then the file just gets > bigger and bigger (and I only have a 16MB SDRAM to load it from). Either mke2fs directly on the MTD device, or use resize2fs to enlarge the filesystem to fill the full MTD device. Or make sure the large image is a sparse file, then it needs less disk space. > >maybe you will get more answers on the linux-mtd mailing list.

BTW, be careful with ext2 on flash, you really want it mounted noatime,nodiratime or otherwise every file access will update the atime information and cause needles wear on the flash block that contains the atime for that particular file.
