Installation

Features

• Big/Little Endian support
• JFFS2_COMPR_ZLIB, JFFS2_COMPR_RTIME, JFFS_COMPR_LZO and JFFS2_COMPR_LZMA compression support
• CRC checks - for now only enforced on hdr_crc
• Extraction of symlinks, directories, files, and device nodes
• Detection/handling of duplicate inode numbers. Occurs if multiple JFFS2 filesystems are found in one file and causes jefferson to treat segments as separate filesystems
