@maxpol I2C3 I2C5 cannot be changed to other pinsOf course, you can try opening other I2C channels.

CPU

测试方法：

sudo apt install sysbench

RK3588S单核心每秒事件数2598，8核每秒事件数13846；同步对比 i7-7700 ，单核每秒事件数1438，8核每秒事件数8469。可见ARM在CPU方面并不比X86弱。

GPU

测试方法：

sudo apt-get install glmark2* -y

X11 gl

X11 gles 3.1

WAYLAND gl

WAYLAND gles 3.1

The current human-computer interaction interface of uboot is not yet perfect. We are trying to do this and will notify you of the version launch as soon as possible. Thank you for your support.

@zensation The radiator can be matched with raspberry pi. A separate fan is OK. Normally, it is not necessary to add aluminum alloy fins on the CPU.

内核已经更新，同步develop代码到最新，编译替换内核，KO文件解压到/lib/modules目录，重启机器会看到两个WIFI节点。

使用其中一个连接外网

另外一个可以作为热点

The Ubuntu 24.04 image has really been released and can be obtained from Baidu Cloud or Onedrive. Thank you for your support.

• By default, the Cockpit package is included in the Ubuntu 22.04 default repository. You can install it by running the following command:

    sudo apt-get install cockpit -y

• After installing Cockpit, run the following command to install the Podman module:

    sudo apt-get install cockpit-podman -y

• After installing Cockpit, start the Cockpit service and have it start when the system reboots:

    systemctl start cockpit
    systemctl enable cockpit

• You can also use the following command to check the status of Cockpit:

     systemctl status cockpit

• You should see the following output:

●cockpit.service - Cockpit Web Service
     Loaded: loaded (/lib/systemd/system/cockpit.service; static)
     Active: active (running) since Tue 2023-11-21 08:44:56 UTC; 7min ago

• At this point, Cockpit has started and is listening on port 9090. You can use the following command to view:

     ss -antpl | grep 9090

• You should see the following output:

     LISTEN 0      0                  *:9090            *:*

• Configure a UFW firewall and open port 9090

• Now, open a web browser and use the URL https://your-server-ip:9090 Access the Cockpit web interface. You should see the Cockpit login page:
  
  

@tonyone0902 数据格式的问题可能性比较大。

The latest ubuntu22.04 firmware（20230303-ubuntu-22.04-preinstall-desktop-arm64） integrates ffmpeg and gstreamer video frames, and can call the hardware codec module of Rockchip, which can greatly improve the video codec performance of the device and reduce the CPU load.

• With kmssink, the CPU utilization of 4K video playback is reduced to about 10%.The disadvantage is that it occupies one layer.

• The following command can obtain layer information.

   sudo cat /sys/kernel/debug/dri/0/state | grep "plane"

• Use the following command to play the video and replace xxx.mp4 with the actual path. 88 represents the layer, kmssink only supports the display of Esmart layer.

   gst-play-1.0  xxx.mp4 --videosink='kmssink plane-id=88'

• You can also use other plug-ins, such as xvimagesink glimagesink waylandsink, etc.

1.First, download the image to the COOLPI laptop
2.Then insert the USB drive into the laptop, double-click on the image and the following interface will pop up. 3.Then select the USB drive, and the image will be created into the USB drive
4.Restart the laptop and the machine will boot from the USB drive. After entering the system, copy the 24.04 image into the USB drive.
5.Double click on the 24.04 image in the USB drive directory, select EMMC (starting with AT29), and enter the root password. The image will be flushed into EMMC.

不会的！DCDC输入的电压可以到30V以上。超过12V的电源输入建议使用2PIN 2.54mm连接器，如下图所示：正常工作12V 1.5A就可以满足系统要求，如果有加其它外设比如移动硬盘 SSD之类的，根据实际情况增加电源功率。

不同的格式对齐要求不同，RGA硬件本身是对图像每行的数据是按照字（world）对齐的方式进行取数的，即4个字节32个bit。例如RGBA格式本身单个像素存储大小为32（4 × 8）bit，所以没有对齐要求；RGB565格式存储大小为16（5 + 6 +5）bit，所以需要2对齐；RGB888格式存储大小为24（8 × 3）bit，所以该格式需要4对齐才能满足RGA硬件的32bit取数要求；YUV格式存储相对较为特殊，本身排列要求需要2对齐，Y通道单像素存储大小为8bit，UV通道根据420/422决定每四个像素的存储大小，所以YUV格式Y通道需要4对齐才能满足RGA的硬件取数要求，则YUV格式需要4对齐；其他的未提及的格式对齐要求原理相通。注意，该题中对齐均指width stride的对齐要求，YUV格式本身实际宽高、偏移量由于格式本身特性也是要求2对齐的。

You can download the image again to the 24.04 system directory. If you downloaded to 22.04 before, you must first mount mmcblk0p2 to the system and then find the image you downloaded earlier in the corresponding folder.

Closing the laptop cover will put the machine into sleep mode.

Recently, I have been working hard to push CM5 NOTEBOOK to the ARMBIAN mainline. Further information will be released as soon as possible. Thank you for your support.

The kernel version 6.1 will support it and is currently being adapted.
