//到这里USB驱动支持自动挂载和卸载

可能是板子原因不支持中文显示，‘？’就是中文

支持FAT32格式的读写，可以试着往U盘mkdir文件夹

支持NTFS格式的读，但不支持写

至于自动自动挂载卸载的问题，在根文件系统rootfs下添加mdev.conf文件

mdev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)

在这里最好取消掉注释，因为有些Ｕ盘识别为ＵＢ开头，如果没取消可能会识别不了Ｕ盘
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
