Z509 Reference Manual V1.1
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 Z509). 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.

1.2 Recovery Mode
Jetson Xavier NX core module can work in normal mode and Recovery mode, under which file system
update, kernel update, Boot Loader update, BCT update and other operations can be carried out.
The steps to enter the Recovery mode are as follows:
a) Turn off the power supply to the system.
b) Use a USB cable connection RTSS-Z509’s OTG-USB port with Jetson develop host USB port.
c) Short connect 1 and 9 pins of Button connector and supply power to the system. The power supply
shall be maintained for more than 3 seconds, and then disconnect 1 and 9 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.
Z509 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

3. Test your device can connect via ssh.
4. Use SDK Manager to select and install the required components.
Download and install the NVIDIA SDK Manager on the Linux host.
You must have a Linux host with internet access to run SDK Manager and refresh the developer kit. The
supported host operating systems are:
Ubuntu Linux x64 Version 18.04 or 16.04
Download and install NVIDIA SDK Manager.
sdkmanager Installation package：sdkmanager-[version].[build#].deb
The current version is：sdkmanager_1.2.0

Realtimes Beijing Technology Co.,LTD www.realtimesai.com
Z509 Reference Manual V1.1
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 Micro 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 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 Micro 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 NX System Programming Manual".
