NVIDIA Jetson NX, AI configuration. Install SDK Components
Reference 2
Jetson Xavier NX flashing process- Zhihu (zhihu.com)
1. Preparation before flashing
Hardware and software: virtual machine VMware Workstation. A Dupont cable, original Android data cable, keyboard, mouse, monitor, etc.
2. Install the Ubuntu virtual machine
https://blog.csdn.net/qq_64079631/article/details/127935249Install ubuntu20.04 in the virtual machine, minimal installation. , The virtual machine disk must be at least 60G , otherwise it may fail.
You may be prompted later that the disk space of the virtual machine is not enough. There are two methods at this time, 1. Expand the disk of the virtual machine, 2. Do not expand, download the system first, and do not download the components first. After burning the system, download it again Component burning
3. Install SDK Manager
Open Ubuntu and download it from NVIDIA SDK Manager | NVIDIA Developer.deb . There is a U disk, no need to download it
After the download is complete Ctrl+T , open Terminal and execute the command sudo apt install ./sdkmanager.....amd64.debto install SDK Manager.
4. Burning system
Start the SDK Manager
Execute in Terminal sdkmanager, log in with the account you want to use NVIDIA for the first time
After successful login, enter the download and burn interface. At this point, we don't need to connect to the development board for the time being , we will download and compile the system and components first.
STEP01：
Select the hardware platform Xavier NX, choose 5.0.2【rev.2】for Linux;
click continue
STEP02：
Select the download item, as indicated by 1 and 2 in the figure, which are system and component respectively;
Check 3, which means download first, and then burn later;
Check 4 agree, click continue;
Copy the Downloads folder of the U disk to the main directory, without downloading, go directly to start burning
It prompts that the download path does not exist, click Create;
STEP03：
Start downloading and compiling. If the network is good, it will take about 1 hour; (if interrupted in the middle, you need to return to the previous step and continue again)
STEP04：
When the download is complete, click finish.
Next, prepare to connect the development board for programming.
burning
Development board preparation:
Short connect GND and FC REC (the second from the right and the third from the right) with a Dupont cable to make NX enter recovery mode, then use the built-in Android data cable to connect NX to the computer, then connect the mouse, keyboard, and monitor to NX, and finally plug in the power .
system programming
Short circuit the NX development board Connect the MicroUSB to the computer Power on
Choose to connect the development board to the virtual machine
Open the terminal and enter lsusb and the connection is successful if it appears as shown in the figure. If you can’t connect, check whether your cable is a data cable instead of a charging cable, or check your virtual machine settings
open sdkmanger
Log in
choose the first
It will automatically recognize that NX stands for OK
Next step
Enter the password for this virtual machine at this time, and you're ready to go.
A popup appears.
Select as above:
Click Finish and wait for the burning to complete.
probably can brush
Disconnect the shorted Dupont wire
Start NX
NX connects HDMI to the display and connects to the Internet (wifi or network cable). Mouse and keyboard, power on
Ubuntu20.04 starts to start, and you can configure user name, password and other information at this time
Successfully entered into Ubuntu
Download the Chinese language pack in the Ubuntu system
Right-click Settings, Region&Language, Manage install Language, Install, Install/Remove Language, only check Chinese (simplified), Apply
restart the system
Ubuntu system change apt source
You can change the source according to the method of Ubuntu in the virtual machine, or you can follow the method below.
Backup source:sudo cp /etc/apt/sources.list /etc/apt/sources.list.bat
Edit the new source file:sudo gedit /etc/apt/sources.list
Add the following to the file

Execute sudo apt-get update and sudo apt-get upgrade update.
Set SSD boot items
Open the application menu in ubuntu and find the Disks disk
Start the disk application, you can see the 128GB Disk, select it, click the three dots in the upper right corner to select Format Disk（格式化磁盘）, and format it.
Click Formatto select the EXT4 format.
After the formatting is complete, all become Free Space.
点击 + ， Free Space FollowingChoose 16GB.
Give the volume a name, create.
Copy system files from emmc to SSD
Clone the GitHub project and execute the commands in sequencegit clone https://github.com/jetsonhacks/rootOnNVMe.gitcd rootOnNVMe./copy-rootfs-ssd.sh
3) Set to boot from SSD
./setup-service.sh
Restart, execute df -h, and see that the SSD device usage is greater than zero.
View the ip address of NX
Command: ifconfig , remember the ip, it will be used later.
Next burn the components
When burning the SDK, you don’t need to plug in the DuPont cable, run the SDK Manager, only select the second item in SETP02 Jetson SDK Components, and keep the rest unchanged. Continue to install until the installation is complete.
Check that
under NX Ubuntu20.04, download jtop and check whether the SDK is installed successfully
Command line input:
sudo apt-get update
sudo apt install python3-pip -y
sudo pip3 install jetson-stats -i https://pypi.douban.com/simple/
Restart Ubuntu20.04
sudo jtop
press 7

CUDA10.2 has been installed by default, but there is no configuration, you need to write the CUDA path into the environment variable.
Open the .bashrc file and execute the command:
sudo gedit ~/.bashrc
Add the following at the end of the file:
export PATH=/usr/local/cuda/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
export CUDA_HOME=/usr/local/cuda
Then update, execute:
source ~/.bashrc
Check whether the CUDA environment is configured
nvcc -V
At this point, the system is finished
