手头上拥有一个.ubi的文件，如果要对它进行修改，或者通过nfs挂载，那么首先必须要做的事情就是，把这个ubi文件展开。其中展开的命令nandsim中必须要有四个id byte，那么这个应该如何确定呢？请看如下列表。

modprobe nandsim first_id_byte=0x20 second_id_byte=0x33 #16MiB, 512 bytes page;
modprobe nandsim first_id_byte=0x20 second_id_byte=0x35 #32MiB, 512 bytes page;
modprobe nandsim first_id_byte=0x20 second_id_byte=0x36 #64MiB, 512 bytes page;
modprobe nandsim first_id_byte=0x20 second_id_byte=0x78 #128MiB, 512 bytes page;
modprobe nandsim first_id_byte=0x20 second_id_byte=0x71 #256MiB, 512 bytes page;
modprobe nandsim first_id_byte=0x20 second_id_byte=0xa2 third_id_byte=0x00 fourth_id_byte=0x15 #64MiB, 2048 bytes page;
modprobe nandsim first_id_byte=0xec second_id_byte=0xa1 third_id_byte=0x00 fourth_id_byte=0x15 #128MiB, 2048 bytes page;
