??.mp3 ????????????????????.docxmdev会在/etc目录下找mdev的配置文件: mdev.conf. 如果该文件不存在，那么在执行mdev –s这个命令时，
会提示找不到mdev.conf，这时我们可以建一个空的mdev.conf文件解决这个问题。下面创建使用mdev自动挂载u盘和SD卡的配置etc/mdev.conf
vim etc/mdev.conf
sd[a-z][0-9] 0:0 0777 @(mount /dev/$MDEV /mnt/usb)
sd[a-z] 0:0 0777 $(umount /mnt/usb)
ub[a-z][0-9] 0:0 0777 @(mount /dev/$MDEV /mnt/usb)
ub[a-z] 0:0 0777 $(umount /mnt/usb)
mmcblk[0-9]p[0-9] 0:0 0777 @(mount /dev/$MDEV /mnt/sdc)
mmcblk[0-9] 0:0 0777 $(umount /mnt/sdc)
@表示在创建设备节点后运行命令。
$表示
在删除设备节点前运行命令。
$MDEV 会被设置成设备名，例如mdev解析到设备 'sdb' 匹配，MDEV 将会被设置为 "sdb"
之前做ＵＢＩＦＳ文件系统时，为了确保文件系统挂载到根目录下，注释掉了这两行
＃ub[a-z][0-9] 0:0 0777 @(mount /dev/$MDEV /mnt/usb)
＃ub[a-z] 0:0 0777 $(umount /mnt/usb)还有一个问题就是某些牌子的Ｕ盘会识别不了，就算是FAT32也识别不了，估计是内核
的问题，但总的来说大多都可以识别挂载
下面说说怎么添加对NTFS写的支持
make menuconfig
File systems --->
<*>FUSE (Filesystem in Userspace) support //支持用户空间文件系统，这样就可以使用ntfs-3g挂载
<*> Character device in Userspace support
先安装ntfs-3g,使用源码安装，因为ntfs是给ＡＲＭ使用的，所以先配置，要用到交叉编译器
[luminqi@localhost 3rdparty]$ wget https://tuxera.com/opensource/ntfs-3g_ntfsprogs-2017.3.23.tgz
[luminqi@localhost 3rdparty]$ tar zxvf ntfs-3g_ntfsprogs-2017.3.23.tgz
[luminqi@localhost 3rdparty]$ cd fl2440/3rdparty/ntfs-3g_ntfsprogs-2017.3.23
[luminqi@localhostntfs-3g_ntfsprogs-2017.3.23]$ ./configure CC=/opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-gcc RANLIB=/opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-ranlib LD=/opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-ld --build=i686 --host=arm-linux --prefix=/home/luminqi/ntfs
关于上面这个命名就是为了配置，为了给ARM使用
CC对应arm-linux-gcc，这个一般都要有
RANLIB对应arm-linux-ranlib
LD对应arm-linux-ld
//对于RANLIB和LD，因为之前没添加上就make，报错说要添加上这两个参数，说明要编译ＡＲＭ版本的话这两个参数不可缺少，注意要大写，不要小写
--build 指定软件包安装的系统平台.如果没有指定,默认值将是'--host'选项的值.
--host 指定软件运行的系统平台.如果没有指定,将会运行`config.guess'来检测.
--prefix 安装路径，是最常用的选项.制作出的'Makefile'会查看随此选项传递的参数,当一个包在安装时可以彻底的重新安置他的结构独立部分，最好添加．
[luminqi@localhost ntfs-3g_ntfsprogs-2017.3.23]$ make
[luminqi@localhost ntfs-3g_ntfsprogs-2017.3.23]$ make install
[luminqi@localhost ntfs-3g_ntfsprogs-2017.3.23]$ find -iname "ntfs-3g"
./include/ntfs-3g
./src/.libs/ntfs-3g
./src/ntfs-3g
[luminqi@localhost ntfs-3g_ntfsprogs-2017.3.23]$ cd src/.libs/
[luminqi@localhost .libs]$ file ntfs-3g
ntfs-3g: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), not stripped
[luminqi@localhost .libs]$ cd /home/luminqi/ntfs/
[luminqi@localhost ntfs]$ mv lib/libntfs-3g.so.88.0.0 lib/libntfs-3g.so.88
使用命令file libntfs-3g.so.88
发现是arm支持的
先make下内核，重新烧到开发板
接下来将ntfs-3g和libntfs-3g.so.88传到开发板
依次放在/usr/bin 和/usr/lib
bin 目录下 tftp -gr ntfs-3g 192.168.1.2
lib 目录下 tftp -gr libntfs-3g.so.88 192.168.1.2
主目录下 chmod a+x /usr/bin/ntfs-3g
在/mnt/下新建文件夹ntfs
接上NTFS格式的U盘，这时会自动挂载
/dev/sda1 on /mnt/usb type ntfs 但是挂载在这里还是不支持写
先手动卸载
umount /mnt/usb
再手动挂载，用到ntfs-3g这个工具
/usr/bin/ntfs-3g /dev/sda1 /mnt/ntfs -o silent,umask=0
这样总算支持了NTFS的写！
当然如果要自动挂载到 /mnt/ntfs,就要修改根文件系统里的etc/mdev.conf,重新制作jffs2文件系统
