3.Recovery mode
Leetop_ALP_681_F can update the system through USB, and the update needs to enter the USB
Recovery mode. In USB Recovery mode, you can perform file system update, kernel update, boot
loader update, BCT update and other operations.
Steps to enter Recovery Mode:
1.Power off the system, make sure to power off and not go into standby;
2.Use the USB Type C to USB Type A link cable to link the carrier board and the host;
3.Power on the device and enter Recovery mode;
4.After pressing the recovery button and the reset button for two seconds at the same time,
first release the reset button and then release the recovery button to make it enter the rec
mode.
Note: In the USB Recovery mode, the system will not start, and the serial port will not have
debugging information output
4.Install system image
a) Connect USB type-A of Ubuntu 18.04 Host to Type-c of Leetop_ALP_681_F ;
b) Power up Leetop_ALP_681_F and enter Recovery mode(RCM);
c) The PC Host enters the L4T directory and executes the flashing instruction：
d) After flashing, power on Leetop_ALP_681_F again and log in to the system.
5.Switching working modes
After logging in to the system, you can click on the operation modification in the upper right
corner of the system interface, as shown in the figure:
Or, enter the command in the terminal to switch:
6. Install cuda
cd Linux_for_tegra
#Use this command for the first time to generate system.img
sudo ./flash.sh jetson-agx-orin-devkit mmcblk0p1

Use of xshell
Xshell is a powerful security terminal emulation software, it supports SSH1, SSH2, and TELNET
protocol of Microsoft Windows platform. Xshell's secure connection to remote hosts through the
Internet and its innovative design and features help users enjoy their work in complex network
environments. Xshell can be used to access servers under different remote systems under the
Windows interface, so as to better achieve the purpose of remote control of the terminal. xshell
is not necessary, but it can better assist us in using equipment. It can link your Windows system
with your Ubuntu system, allowing you to operate your Linux system under Windows system. To
install xshell, you can download and install it by searching Baidu on the Internet. (When the
product cannot enter the desktop system, you can also use xshell to perform remote control and
modify configuration errors).
