快速入门 (Quick Start)

系统下载 (OS Download)

Jetpack 6.2

Jetpack 5.1

Linux 燒錄方法 (Linux Flash eMMC Method)

1.Prepare a Linux host system Ubuntu x64 v18.04. Download the image file and unzip the image.tar.gz file on Linux host PC. Example use image version 7300A1AIM35UIV20026.tar.gz.

$ sudo tar zxvf 7300A1AIM35UIV20026_2023-07-03.tgz
$ cd Linux_for_Tegra

2.Enter to recovery mode by holding the recover button (SW1) and plug power to boot. Release recover button around 3 seconds after plug in power.

Or enter following command in the device.

$ sudo reboot --force forced-recovery

3.Connect Micro USB cable from EPC-R7200 Micro USB port to Linux host PC USB TypeA port. Check the device is in recovery mode by command “lsusb”. Will get NVidia Corp. with ID 0955:7623

Bus 001 Device 072: ID 174c:2362 ASMedia Technology Inc. ASM236X series
Bus 001 Device 073: ID 05ac:12a8 Apple, Inc. iPhone5/5C/5S/6
Bus 001 Device 074: ID 0955:7623 NVIDIA Corp. APX
Bus 001 Device 003: ID 0bda:0169 Realtek Semiconductor Corp. Mass Storage Device

4.Execute command to flash imag:

For Jackpack 5.1.1:

(1) To flash QSPI + NVME SSD:

$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_external.xml -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" --showlogs --network usb0 jetson-orin-epcr7300-a1 internal

(2) To flash only QSPI:

$ sudo ./flash.sh --no-systemimg -c bootloader/t186ref/cfg/flash_t234_qspi.xml jetson-orin-epcr7300-a1 mmcblk0p1

(3) To flash only NVMe SSD (Need to flash QSPI first):

$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-only --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_external.xml --showlogs --network usb0 jetson-orin-epcr7300-a1 internal

For Jackpack 6.2:

(1) To flash QSPI + NVME SSD:

$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_external.xml -p "-c bootloader/generic/cfg/flash_t234_qspi.xml" --showlogs --network usb0 jetson-orin-nano-devkit-super internal

(2) To flash QSPI + USB DISK:

$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device sda1 -c tools/kernel_flash/flash_l4t_external.xml -p "-c bootloader/generic/cfg/flash_t234_qspi.xml" --showlogs --network usb0 jetson-orin-nano-devkit-super internal

5.Wait around 10~15 minute to flash image to device:

If you get the below "strings: command not found" error, please install "binutils"

6.Check the device login to system:

login user: ubuntu/ubuntu

7.Check the eth1 can get the IP Addr:

Debug 串口調試 (Debug port Setting)

以 Tera Term  为例介绍如何使用串口调试功能

   Baud Rate波特率：115200
   Data 数据位：8
   Parity 奇偶校验：无
   Stop 停止位：1
   Flow Control流控：无

Tera Term Tool 

Check the Sriel port in Device Manager (查看PC端的串口号)：

if you can not identify the Serial device , please check your serial driver. 

Debug port connection (串口連接) 

Log into Terminal  Tool (进入串口调试终端)：

login user: ubuntu/ubuntu

Linux 基本使用方法 for jetson series(Linux System Basic Operating Method for jetson series)

• check module

$ jetson_release

$ cat /proc/device-tree/model

• check OS release version

$ cat /etc/os-release

• check tegra version

$ cat /etc/nv_tegra_release

• Install stress-ng 

$ sudo apt install stress-ng

• Execute stress test

$ stress-ng --cpu 0 --cpu-method all -t 1h

• Install jtop

$ sudo apt update
$ sudo apt install python3-pip
$ sudo pip3 install -U jetson-stats
$ jtop

• Install chromium

$ sudo snap install chromium

If there is issue cannot launch chromium, please reference lionk below to download grade snap version:

chromium not working

• Install nvidia-jetpack

$ sudo apt install nvidia-jetpack

Modify defconfig: If an unknown symbol issue occurs after modifying the defconfig, please refer to the compiled information below.

It may fail with additional steps. Please simply follow the steps:
1) And follow the steps to rebuild kernel, out-of-tree modules, and dtbs:

2) Manually copy the files: ( quick fix for a known issue: https://forums.developer.nvidia.com/t/319667/ )

$ cd <install-path>/Linux_for_Tegra/rootfs/lib/modules/5.15.148-tegra/updates/
$ sudo cp nvidia.ko opensrc-disp/
$ sudo cp nvidia-modeset.ko opensrc-disp/
$ sudo cp nvidia-drm.ko opensrc-disp/

3) Flash the system
$ cd <install-path>/Linux_for_Tegra/
$ sudo ./flash.sh jetson-agx-orin-devkit internal
