=== Description ===
This guide describes how to setup USB Mass Storage on Radxa E25.

=== Requirement ===
* Radxa E25
* Ubuntu PC or Windows PC
* USB Male A to A cable

=== Enable USB mass storage on Radxa E25 ===

* Step 1: Disable amlogic-adbd service. It will interfere with USB mass storage mode:

rock@radxa-e25:~$ sudo systemctl disable rockchip-adbd

* Step 2: Reboot the device:

rock@radxa-e25:~$ sudo reboot

* Step 3: Create a file backing for mass storage, and format it in FAT32:

rock@radxa-e25:~$ sudo dd if=/dev/zero of=/home/rock/share bs=1M count=512 status=progress # Create a 512M file as /home/rock/share
rock@radxa-e25:~$ sudo apt-get install dosfstools # dosfstools contains mkfs.fat
rock@radxa-e25:~$ sudo mkfs.fat /home/rock/share -F 32 -I

* Step 4: Enable USB mass storage on our backing file and create test.txt file:

rock@radxa-e25:~$ sudo modprobe g_mass_storage file=/home/rock/share stall=0 removable=1
rock@radxa-e25:~$ sudo mount /home/rock/share /mnt/
rock@radxa-e25:~$ sudo touch /mnt/test.txt
rock@radxa-e25:~$ echo "hello radxa" | sudo tee /mnt/test.txt
hello radxa
rock@radxa-e25:~$ cat /mnt/test.txt
hello radxa

=== Accessing storage device from PC ===
