The released system mainly addresses some minor issues from the previous version, upgrades some software packages, and optimizes configurations to make the system run more stably. At the same time, some friends wanted to install Gazebo on the Raspberry Pi, I tested it, and it can indeed be opened, but it is very laggy and basically unusable. It seems to be a GPU memory issue with the Raspberry Pi, as the CPU usage is not very high. This issue has not been resolved yet, but it will be attempted in future versions.System Update Log

0x01 System Download
The latest system can be downloaded from Baidu Cloud, and everyone can download and experience it first. If you feel satisfied after using it, you can purchase the system activation code for formal use. The trial can only be used for 6 power cycles, and after the trial ends, the ROS-related functions in the system will stop working. The other functions of the Raspberry Pi will not be affected, and at this time, this system can be used as a normal official Raspberry Pi system. The Baidu Cloud download link is as follows:
If you have previously purchased an activation code, there is no need to purchase it again; you can use the previous activation code to activate this newly released system. However, it is important to note that the activation code is hardware-bound to the Raspberry Pi main board. If you change to a new Raspberry Pi main board, you will need to use a new activation code. If you need to purchase the Raspberry Pi ROS system activation code, you can click the following link to purchase:

System Activation Operation
0x02 Precautions
[1]. This Raspberry Pi system is based on Ubuntu Server 20.04 ARM64 and can run normally on Raspberry Pi 3 series, 4B, and Raspberry Pi Pi 400 boards (which look like a keyboard).
[2]. The default username for the system is corvin, and the password is also corvin. The password for the root user is also corvin, and the default password can be changed by the user.
[3]. The system has defaulted to enable SSH server on port 22, VNC server on port 5900, and FTP service on port 21, making it convenient for SSH connections, VNC remote desktop, and FTP connections.
[4]. The SD card of the activated system can only be used on the Raspberry Pi mainboard it was bound to during activation. If the SD card is inserted into another Raspberry Pi mainboard, only the ROS functions will be deleted.
[5]. This system is the ROS system installed after upgrading and adapting the latest official Ubuntu Server 20.04, so you can directly use apt to install ROS Noetic related software packages.
