@anernest Please upload a copy of dmesg information. Thank you.

• 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
TriggeredBy: ● cockpit.socket
       Docs: man:cockpit-ws(8)
    Process: 336904 ExecStartPre=/usr/lib/cockpit/cockpit-certificate-ensure --for-cockpit-tls (code=exited, status=0/SUCCESS)
   Main PID: 336905 (cockpit-tls)

     CGroup: /system.slice/cockpit.service
             └─336905 /usr/lib/cockpit/cockpit-tls

• 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:
  
  

@jugg 文件系统损坏了！该刷机就刷机！当让也可以用TF卡或者U盘启动，备份数据。

@jugg
尝试把流控关闭。

@airobot机器人开发 好的！正常编译完内核以后需要把modules.tar.gz 解压到文件系统的/lib 目录，这里边主要是一些驱动的ko文件。

@qys2022 不使用NC就好了。不用接高或者低

@airobot机器人开发 系统镜像做到TF卡或者U盘里边，默认TF卡或者U盘启动优先级高于EMMC，系统启动后手动挂载EMMC分区就可以导出数据了。

@Momo-0
Thank you for sharing. If you have any questions during use, I hope you can raise them. Thank you very much for your support.

@阿里 系统镜像可以重新刷一下，如果有修改导致图像界面启动不了的话。

@阿里 这个系统已经正常启动。两个HDMI接口可以交换测试。

@阿里 跑的什么系统，另外注意电源功率是否够。

RS这颗物料市场上很少能买到样品，你可以用如下链接的替换型号，功能和PIN定义完全一致：

这款用的是COOLPI CM5的核心板，不兼容第三方的。

@anernest

• This screen CM5 can be supported, and you need to create a separate adapter board or adapter cable to be compatible with its PIN sequence.

• The DSI interface of CM5 is shown below, including 2 sets of independent 4LINE DSI channels, 2 sets of I2C interfaces, etc., which can simultaneously drive two DSI interfaces for LCD, with a resolution of 2560 * 1600

• It should be noted that the level of some IO is 1.8V, which requires a level conversion circuit to 3.3V.

问题1：uboot是否开源并且支持修改调试? github上有uboot源码，支持修改调试。https://github.com/orgs/yanyitech/repositories
问题2：设备树dts是否开源，比如我可以挂载一个slave到i2c控制器上，我可以在设备树上添加； 内核代码也是开源的，支持修改。

问题3：CM5原厂有没有维护一个linux kernel版本，如果有的话，是否提供；Github上面有

问题4：想使用nfs挂载根文件系统，有没有相关的文档教程之类的；这个自行网络搜索解决。

@Albert 可以的。

@Albert
1.电源是配器可以选择标准的TYPEC是配器，支持12V/1.5A以上输出功率。
2.可以支持uefi,，目前EVB的机器支持nvme 2242规格的SSD.可以把系统安装到ssd或者标准SATA硬盘里边。

@anernest
Thank you for your support. We will cooperate and support any issues that may arise in the future. And if you choose an LCD, you can also send it to us to confirm if it is supported.

@anernest
Thank you for your suggestion. We will consider supporting you in the future.

@etrin
You can obtain the version of CP310 from the following website.
https://download.pytorch.org/whl/cpu/torch_stable.html

@etrin
This is related to the system's Python. If using ubuntu22.04, the Python version is 3.10. You can also try lowering the system's Python version, but it may cause other issues.

@anernest
Please provide the specifications of the monitor and the PIN definition of the interface, and we will evaluate whether it can be supported？

@qys2022 PCIE差分对NP可以交叉的，控制器会自动识别。

@Momo-0
There is no abnormal log information found in the dmesg information. Do you have any USB to serial port tools in your hand, and do you have some hands-on skills, such as welding and debugging serial ports. If further debugging information needs to be obtained, it is necessary to capture the logs of the serial port sleep wake up section to confirm the direction of the problem.

@anernest
This product is designed for enthusiasts and is very suitable for DIY users to develop, assemble, and build their own. Currently, after dismantling the machine, they do not enjoy after-sales policies. However, various accessories of the machine, including motherboards, core board and shell materials, can be sold separately for secondary sales. And we have a dedicated team to assist users in solving various problems in use and design. Notebook products are an extension of the CM5 core board, and currently there is no separate theme in the community. If you have any questions, you can directly post them under the CM5 theme. Thank you for your support.

• The latest laptop motherboard design has changed the WiFi section to a standard M2 interface, making it easy for users to replace according to different needs. Early machines can also be upgraded by replacing the motherboard.

After booting up, print a dmesg message and send it out. I think this should be a single machine issue. Normally, our machine does not have this problem.

@Momo-0
Configure according to the factory's configuration (both the file system and kernel are placed in EMMC, while nvme only serves as a data disk). Is there a problem with suspend?

@etrin Has the problem been solved now？
