Usage: mkfs.ubifs [OPTIONS] target
Make a UBIFS file system image from an existing directory tree
Examples:
Build file system from directory /opt/img, writting the result in the ubifs.img file
        mkfs.ubifs -m 512 -e 128KiB -c 100 -r /opt/img ubifs.img
The same, but writting directly to an UBIFS volume
        mkfs.ubifs -r /opt/img/dev/ubi0_0
Creating an empty UBIFS filesystem on an UBIFS volume
        mkfs.ubifs/dev/ubi0_0
Options:
-r, -d, --root=DIR         build file system from directory DIR, 待制作的⽂件系统⽬录
-m, --min-io-size=SIZE     minimum I/O unit size，最⼩输⼊输出⼤⼩, NAND FLASH 的最⼩读写单元，⼀
般为 page size，有 4096 或 2048
-e, --leb-size=SIZE        logical erase block size 逻辑可擦出块⼤⼩，为 block size-2x (page
size)，如 block_size 256KB page_size 2KB 应设置 -e 258048，如 block_size 128KB page_size 2KB 应
设置 -e 126976
-c, --max-leb-cnt=COUNT    maximum logical erase block count 最⼤逻辑可擦出块数⽬，autoresize 时
⽂件系统的的上限
-o, --output=FILE          output to FILE 输出⽂件名
-j, --jrn-size=SIZE        journal size
-R, --reserved=SIZE        how much space should be reserved for the super-user
-x, --compr=TYPE           compression type - "lzo", "favor_lzo", "zlib" or "none" (default:
"lzo")
-X, --favor-percent        may only be used with favor LZO compression and defines how many
percent better zlib should compress to make mkfs.ubifs use zlib instead of LZO (default 20%)
-f, --fanout=NUM           fanout NUM (default: 8)
-F, --space-fixup          file-system free space has to be fixed up on first mount(requires
kernel version 3.0 or greater),如果是通过 u-boot 烧写需要使能此功能。
-k, --keyhash=TYPE         key hash type - "r5" or "test" (default: "r5")
-p, --orph-lebs=COUNT      count of erase blocks for orphans (default: 1)
-D, --devtable=FILE        use device table FILE
-U, --SquashFS-uids        SquashFS owners making all files owned by root
-l, --log-lebs=COUNT       count of erase blocks for the log (used only for debugging)
-v, --verbose              verbose operation
-V, --version              display version information
-g, --debug=LEVEL          display debug information (0 - none, 1 - statistics, 2 - files, 3
- more details)
-h, --help                 display this help text
