1. Background introduction

Note: In order to ensure that ROSMASTER X3 car can start normally, users need to ensure that the JetPack version in their Jetson board system is consistent with the Jetpack version in the ROSMASETR X3 car system provided by Yahboom.

If you did not purchase Yahboom's Jetson board, when using other brands of Jetson board, maybe you will find that ROSMASTER X3 cannot start normally.

The following tutorial provides a detailed solution to this problem.

 

2. Jetson series board and boot media description

  1. About Jetson series board:

    • Jetson Nano board: Use a U disk as the boot medium.

    • Jetson Orin Nano/Jetson Orin NX board: Use a SSD as boot media.

       

  2. About Jetpack version in the boot media system:

    • The U disk(For Jetson NANO) included in the ROSMASTER X3 robot kit has been written with a system image file dedicated to the ROSMASTER X3 car. This system image file include JetPack 4.6

    • The SSD(For Jetson ORIN NANO/ORIN NX) included in the ROSMASTER X3 robot kit has been written with a system image file dedicated to the ROSMASTER X3 car. This system image file include JetPack 5.1.1

       

3. Check the JetPack version on your own Jetson series board

Your Jetson motherboard currently has two cases.

Case-1: You can boot your Jetson board normally, and enter the command terminal normally.

  • Start your Jetson board, enter the operating system and command terminal.

  • Open the terminal, enter the command jtop and press Enter, jtop will display a real-time updated system status page.

  • After the jtop page is displayed, click the menu page 6 INFO with the mouse.

    At this time, the page will display the version information of components such as Jetpack, CUDA, cuDNN, OpenCV, TensorRT, etc.

     

    Take Jetson Nano as an example, as shown below. My current Jetpack system version is 4.6

    image-20241018151114793

     

  • If the jtop tool is not installed in the system, you can refer to the following command to install it.

    # Install pip3
    sudo apt-get update
    sudo apt install python3-pip
    # Install jtop
    sudo -H pip3 install -U jetson-stats
    # Run jtop service
    sudo systemctl restart jetson_stats.service
    # Restart the system
    reboot

 

Case-2: There are no system files in your own U disk or SSD. Currently, you cannot start the Jetson board normally and enter the command terminal.

  • Write Step

Please refer to 4. Write system by SDK Manager in 《Write official system image (SDK)》.

 

Write EMMC boot

Important: Once you have written this boot file into the EMMC of the Jetson NANO SUB board according to the following tutorial, you can directly insert the U disk in the robot car into the Jetson NANO SUB board (or write the car image file we provide into your own U disk).

Then, you can directly start up robot car. Don't worry about the Jetpack version.

1. Make Jetson Nano connect to virtual machine

  • Prepare the Jetson Nano SUB board, jumper cap, display, mouse and keyboard, etc.
  • As shown in the figure below, let Jetson Nano SUB enter the system REC flashing mode.

Connect the jumper cap to the FC REC and GND pins, that is, the second and third pins of the carrier board. As shown below.

Connect the power supply and insert the microUSB data cable.

Since the jumper cap has been connected to the FC REC and GND pins in the previous step, the Jetson NANO board will automatically enter the REC flashing mode after powering on.

Generally, after connecting the Jetson NANO motherboard and the computer via a Micro USB data cable, the following window will pop up on the computer.

We need to select the device to connect to the virtual machine.

2.Start write boot file

  • Please transfer the Jetson_Boot_USB.tar.gz file in the Yahboom tutorials to the Ubuntu 18.04 system and open the terminal to run the decompression command.
xxxxxxxxxx
tar xzvf Jetson_Boot_USB.tar.gz

As shown below.

image-2023041100004

  • After extracted, input following command to enter the Jetson_Boot_USB folder. 
xxxxxxxxxx
cd Jetson_Boot_USB/
ls

As shown below.

image-2023041100005

  • Input following command to write the EMMC boot file.
xxxxxxxxxx
sudo ./flash.sh -r jetson-nano-devkit-emmc mmcblk0p1

As shown below.

image-2023041100006

  • Wait for the file to be written. If successful, the system will prompt "The target t210ref has been flashed successfully. Reset the board to boot from internal eMMC."

As shown below.

image-2023041100007

If an error message appears, please confirm whether the Jetson Nano SUB board is connected normally and enters the flashing mode.

Reconnect according to the first step. And try again.

After the write is completed, please unplug the jumper cap(FC REC and GND pins) of the Jetson Nano SUB, insert the U disk, and restart the Jetson NANO board.

Note: If you are using the virtual machine provided by Yahboom, which already contains the Jetson_Boot_USB file, you do not need to transfer it to the system again.

 

5. Jetson Orin Nano/Orin NX board start step

Case-1: The Jetpack version of your Jetson board is the same as the Jetpack version of Yahboom robot car.
  • Plug in the SSD in the Yahboom car kit to start robot car.

 

Case-2: The Jetpack version for your Jetson board is not the same as the Jetpack version for Yahboom robot car. Or rou can't check the JetPack version on your own Jetson series board
  • Please refer to 《SDKmanager write system》 to write JetPack 5.1.1 to Jetson ORIN board.
  • After successful writing, insert the SSD provided by Yahboom into the Jetson ORIN board, turn on the power switch of the robot car, robot car can start normally.

  • Make Ubuntu18.04 virtual machines to connect Jetson Orin NANO/Orin NX

Before that, we need to complete the following operations to make Jetson Orin Nano into the system REC flashing mode.

Connect the jumper cap to the FC REC and GND pins, that is, the second and third pins of the carrier board, as shown below.

image-2023050900007

image-2023050900008

1)Connect microUSB data cable on Jetson Orin NANO/Orin NX board.

2)Connect power supply cable on Jetson Orin NANO/Orin NX board.

3)Since the jumper cap has been connected to the FC REC and GND pins in the previous step, the Jetson Orin NANO/Orin NX board will automatically enter the REC flashing mode after powering on.

image-20241021151615004

  • In the SDKManager software of the Ubuntu 18.04 virtual machine system, select Target Hardware as Jetson Orin nano module(Or your Orin NX module). And choose JetPack 5.1.1

image-2023050900010

If Target Hardware shows "Not Connected", please confirm whether Jetson ORIN NANO/ORIN NX board has entered REC flashing mode and successfully connected to the virtual machine.

Make sure everything is OK and click "refresh".

image-2023050900011

Jetson Orin NANO is divided into two versions: 4GB/8GB. Please choose according to the actual situation.

If you are currently using 8GB, please select 8GB module (do not select developer).

If you are currently using 4G, please select 4G module.

Generally, after connecting the Orin board to the virtual machine, the system will automatically recognize it.

Click "CONTINUE".

  • By default, Jetson OS and Jetson SDK Components are checked, which means the system and SDK are flashed. We can also select the system OS or software SDK separately, but before writing the software SDK separately, we need to ensure that the system OS has been flashed.

image-2023050900013

Keep the default file download path, choose agree license agreements. Click "CONTINUE" to proceed to the next step.

As shown below.

image-2023050900014

image-2023050900015

As shown below. Enter the password for the virtual machine.

image-2023050900016

At this time, SDKManager will first download the file to be written.

Wait for the file to be downloaded. Then, system will write to the system and SDK.

  • After the system is written, power off the Jetson Orin board and remove the jumper cap between FC REC and GND.

    Connect the display, power on the Jetson Orin board, and check whether the Jetson Orin board can boot normally and enter the system.

If the Jetson Orin board can boot up normally and enter the system, you can disconnect the power supply.

Insert the SSD provided by Yahboom, install the Jetson Orin board on the car, turn on the power switch, and the car can start normally.

 

Note

  • Before performing any write or system update operations, please back up the original important data on the Jetson board. Once written or updated, it cannot be restored.
  • When writing the boot or system, make sure to use the tutorials and tools that match the motherboard model.
  • If you encounter any problems during the startup process, please refer to the official NVIDIA documentation of the motherboard for troubleshooting and solutions.
