		+
		+	=== Requirement ===
		+	* ROCK Pi E mainboard
		+	* eMMC module
		+	* Power adapter
		+	* USB Male A to Dupont cable.
		+	** One port is Male A type and the other includes three Dupont lines.
		+	** Hardware connection

		+	\|}
		+
		+	=== Support ===
		+	Support hardware platform:
		+	* ROCK Pi E V1.1 or later
		+
		+	You'd better follow the installation steps.
		+	=== Operations on ROCK Pi E ===
		+	For example, my testing borad is Rock pi E V1.2 on '''Debian buster''', '''Linux rockpie 4.4.194-19-rockchip-g287ff75afc47'''
		+
		+	You can use [[RockpiS/ssh \| ssh]] or [[rockpiE/dev/serial-console \| serial console]] to access ROCK Pi E.
		+
		+	Step 1: Add the following line to file '''/boot/uEnv.txt'''.
		+
		+	overlays=rk3328-uart2 '''rk3328-usb-otg'''
		+
		+	Step 2: Update rockchip-overlay, kernel, rockchip-adbd kernel packages.
		+
		+	$ sudo apt-get install -y rockchip-overlay
		+	$ sudo apt-get install -y linux-4.4-rock-pi-e-latest
		+
		+	Step 3: Add the following to '''/etc/modules'''
		+	$ cat /etc/modules
		+	# /etc/modules: kernel modules to load at boot time.
		+	#
		+	# This file contains the names of kernel modules that should be loaded
		+	# at boot time, one per line. Lines beginning with "#" are ignored.
		+	'''g_mass_storage'''
		+
		+	Step 4: Reboot the device.
		+	$ sudo reboot
		+
		+	Step 5: Create a file to be a shared space and make it FAT32 type.
		+	$ sudo dd if=/dev/zero of=/home/rock/share bs=1M count=512 status=progress
		+	$ sudo apt-get install dosfstools
		+	$ sudo mkfs.fat /piusb.bin -F 32 -I
		+
		+	Step 6: Enable usb mass storage with the file
		+	$ sudo modprobe g_mass_storage file=/home/rock/share stall=0 removable=1
		+	$ sudo mount /home/rock/share /mnt/
		+	$ sudo touch /mnt/a.c
		+	$ ls
		+	a.c
		+
		+	=== Operations on PC ===
		+	Now, you can see the new partition /dev/sdx is mounted.
		+	$ lsblk
		+	......
		+	sdd 8:48 1 512M 0 disk /mnt
		+	$ ls /mnt
		+	a.c
		+
		+	=== Attention ===
		+	When add files to this shared space, the other side needs to be unmounted and remounted the shared space.For example:
		+
		+	On Rock Pi E:
		+	Create a new file to it.
		+	$ sudo touch /mnt/b.c
		+	$ ls
		+	a.c b.c
		+
		+	On PC:
		+	$ ls /mnt
		+	a.c
		+	It just have one file a.c, new you should remount to update it.
		+	$ sudo umount /mnt
		+	$ sudo mount /dev/sdd /mnt
		+	$ ls /mnt
		+	a.c b.c
