修改分区：

这里是分区的txt文件选择；

这里是分区的划分，我这里回车了，方便看

-@0x00078000(factory:grow)
uuid:rootfs=614e0000-0000-4b53-8000-1d28000054a9

然后后面几个就是我的新增分区；lbcmd、lbflash、lbflash2、lbcfg、lbcfg2、backup、dataro、datarw、factory

编译之后可以看到分区的形成：cat proc/mtd

制作所需挂载点

diff --git a/buildroot/fs/common.mk b/buildroot/fs/common.mk

new mode 100755

编译之后可以看到mnt下面生成挂载点：ro、rw、rwfs

添加config
