進行編譯
$ make
將 nand-part 複製到 /sbin 目錄
$ sudo cp nand-part /sbin

3 partitions
partition 1: class = DISK, name = bootloader, partition start = 32768, partition size = 131072 user_type=0
partition 2: class = DISK, name = rootfs, partition start = 163840, partition size = 8388608 user_type=0
partition 3: class = DISK, name = UDISK, partition start = 8552448, partition size = 22380544 user_type=0
綠色是分割區的名字，粉紅色是分割區的起始位置，橘色是分割區的大小
UDISK 是還未用到的區域，也就是 root 分割區要擴展的區域
擴展之後 /dev/nandb 的大小 8388608+22380544 = 30769152
進行重新分割
$ sudo nand-part -f a20 /dev/nand 32768 ‘boot 131072’ ‘rootfs 30769152’
完成之後，重新啟動電腦
$ sudo reboot
重新設定 /dev/nandb 分割區大小
$ sudo resize2fs /dev/nandb
resize2fs 1.42.8 (20-Jun-2013)
Filesystem at /dev/nandb is mounted on /; on-line resizing required
old_desc_blocks = 1, new_desc_blocks = 1
The filesystem on /dev/nandb is now 3870720 blocks long.
之後的大小
