-Welcome to the discussion

Testing hardware platform-am335x (linux 3.2)

Prerequisites: 1. busybox supports mdev

2. the kernel has reached the USB flash drive.

1) Ship-to-ship rcS script in the etc/init. d/directory

#! /bin/sh/bin/mount -a/bin/SDG800/etc/init.d/sysfs.sh

2) run the sysfs. sh script on the ship under the etc/init. d/directory.

#!/bin/shif [ -e /proc ] && ! [ -e /proc/mounts ]; then  mount -t proc proc /procfiif [ -e /sys ] && ! [ -e /sys/kernel ] && grep -q sysfs /proc/filesystems; then  mount sysfs /sys -t sysfsfimount -t tmpfs mdev /devmkdir /dev/ptsmount -t devpts devpts /dev/ptsecho /sbin/mdev>/proc/sys/kernel/hotplugmdev -sexit 0

3) Create the mdev configuration file under etc

sd[a-z][0-9]  0:0 0660  @/etc/hotplug/usb/udisk_insertsd[a-z]       0:0 0660  $/etc/hotplug/usb/udisk_remove#mmcblk[0-9]p[0-9]  0:0 0660  @/etc/hotplug/sd/sd_insert#mmcblk[0-9]        0:0 0660  $/etc/hotplug/sd/sd_remove

4) create a udisk_insert script file under/etc/hotplug/usb

#!/bin/shecho "MDEV is ${MDEV}"if [ -d /sys/block/*/$MDEV ]  ; then  mkdir -p /media/udisk  mount /dev/$MDEV /media/udisk -t vfat -o utf8=1if [ -f /media/udisk ];thenecho "mount udisk usccessfully"fifi

Create a udisk_remove script file under/etc/hotplug/usb

 #!/bin/shumount -ltf /media/udiskrm -rf /media/udiskecho "remove you udisk safely!"
