Depends on the USB port on host PC, you may need USB A to C(host PC is USB A) or USB C to C(host PC is USB C) cable.<br /> * Mouse, monitor and HDMI Cable<br /> ** To access Radxa E25<br /> * USB to TTL serial cable<br /> ** To access Radxa E25<br /> <br /> === Enable USB mass storage on Radxa E25 ===<br /> <br /> <br /> Step 1: Disable amlogic-adbd service. It will interfere with USB mass storage mode:<br /> <br /> rock@radxa-e25:~$ sudo systemctl disable rockchip-adbd<br /> <br /> Step 2: Reboot the device:<br /> <br /> rock@radxa-e25:~$ sudo reboot<br /> <br /> Step 3: Create a file backing for mass storage, and format it in FAT32:<br /> <br /> 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<br /> rock@radxa-e25:~$ sudo apt-get install dosfstools # dosfstools contains mkfs.fat<br /> rock@radxa-e25:~$ sudo mkfs.fat /home/rock/share -F 32 -I<br /> <br /> Step 4: Enable USB mass storage on our backing file and create test.txt file:<br /> <br /> rock@radxa-e25:~$ sudo modprobe g_mass_storage file=/home/rock/share stall=0 removable=1<br /> rock@radxa-e25:~$ sudo mount /home/rock/share /mnt/<br /> rock@radxa-e25:~$ sudo touch /mnt/test.txt<br /> rock@radxa-e25:~$ echo &quot;hello radxa&quot; | sudo tee /mnt/test.txt<br /> hello radxa<br /> rock@radxa-e25:~$ cat /mnt/test.txt<br /> hello radxa<br /> <br /> === Accessing storage device from PC ===<br /> <br /> After executing command &lt;code&gt;sudo modprobe g_mass_storage file=/home/rock/share stall=0 removable=1&lt;/code&gt; on Radxa E25, a new USB storage device will be detected on your host computer:</div>
