Electronic components and circuits are very sensitive to electrostatic discharge. Although our company
designs anti-static protection for the main interfaces on the card when designing circuit board products,
it is difficult to achieve anti-static safety protection for all components and circuits. Therefore, it is
recommended to observe anti-static safety precautions when handling any circuit board component
(including X508). Anti-static safety protection measures include, but are not limited to the following:
a) The smart box should be placed in an anti-static bag during transportation and storage, and then the
board should not be taken out during installation and deployment.
b) Before touching the smart box, discharge the static electricity stored in the body: wear a discharge
grounding wrist strap.
c) Operate the smart box only within the safe area of the electrostatic discharge point.
d) Avoid moving smart boxes in carpeted areas.

Software version supporting instructions
X508 is a complete product with Jetson Xavier module as the core. Provide developers with one-stop
terminal equipment to assist developers in application development.
X508 Feiyun Smart Box supporting software includes:
- L4T (Linux for Tegra): L4T provides "OS" for your Feiyun Smart Box, including Linux kernel, boot
loader, board support package (BSP) and sample file system. (By default, the pure system has been
installed for the device, Jetpack needs to be installed by itself)
- Jetpack: Jetpack sdk is the most comprehensive solution for building AI applications. It includes
software libraries and apis, examples, developer tools and documentation for the latest and previous
versions of Jetson products.
1 use
1.1 Smart box power on and start
a) Ensure that the voltage of all external systems is turned off
b) Install necessary external cables. (Such as: the display cable connected to the HDMI display, the
power input cable to power the system, the USB cable connecting the keyboard and mouse ...)
c) Connect the power cord to a power source.
d) X508 adopts manual power-on design. Turn on the power and the system starts to work.
1.2 Recovery Mode
Jetson Xavier core modules can work in normal mode and Recovery mode. In Recovery mode, you can
perform file system update, kernel update, boot loader update, BCT update and other operations.
To enter Recovery mode:
a) Turn off the power supply to the system.
b) Use a USB cable connection RTSS-Z508’s Type C USB （P10）port with Host(PC) develop host USB
port.
c) Short connect 15 and 19 pins of Button connector and supply power to the system. The power supply
shall be maintained for more than 3 seconds, and then disconnect 15 and 19 pin short wiring of Button
connector.
d) The system enters the Recovery mode, and subsequent operations can be carried out at this point.
2 L4T（Linux for Tegra Abbreviation“L4T”）
L4T provides "OS" for your Feiyun Smart Box, including Linux kernel, boot loader, board support
package (BSP) and sample file system.
X508 Smart Box is working on a system burned with the official original version of NVIDIA Linux For
Tegra (L4T). HDMI, Gigabit Ethernet, USB2.0, serial port, GPIO, SD card, I2C bus can all be supported. But
Mini-PCIe, M.2, USB3.0, fan interface, etc. cannot work normally.
For all support of X508 smart box interface, the supporting driver patch (BSP: Board Support Package)
needs to be loaded. Use the flash method to program the system. SDK Manager to install all other JetPack
components except L4T to make your Feiyun Smart Box up and running quickly.

sdkmanager install
$ sudo apt install ./sdkmanager-[version].[build#].deb
Connect your jetson device to the Linux host
Prepare your Jetson device for the following settings. (If the equipment system is not initialized, the system
user needs to initialize after power-on)
- Connect the monitor, keyboard and mouse to the Jetson Feiyun smart box device (please refer to the
interface description above).
-Use Type C USB cable to connect Linux host and Jetson Feiyun Smart Box (or network (same network
segment))
-During the setup process, SDK Manager will provide Internet connection for your jetson Feiyun Smart
Box via Type C USB or network connection.
-Connect the supplied power adapter to the DC jack of the Feiyun Smart Box, and plug the AC interface
into an AC power outlet.
Test that your device can connect via ssh.
If connected via Type C USB, enter lsusb under the Linux host terminal to see the nvidia crop
The device can be accessed through ping or ssh commands
$ ping 192.168.55.1
or
$ ssh <jetson_user>@192.168.55.1
If connected via a network, check whether the device ip address is in the same network segment as the
Linux host on the Feiyun Smart Box, and the Feiyun Smart Box device can be accessed through the ping or
ssh command.
$ ping <jetson_ip>
or
$ ssh <jetson_user>@<jetson_device_ip>
Use SDK Manager to select and install the required components
NVIDIA SDK Manager supports installing software to Jetson core (Flying Cloud Smart Box). For
complete instructions, please refer to Chapter 5 of "Xavier System Programming Manual".
