@jugg 进入系统先新建一个管理员账户，重启，使用新建的管理员账户登陆，然后删除coolpi账户即可。

@jugg 默认用户名：coolpi 密码：123，进入系统以后可以自己添加或者修改。

@jugg 升级最新版本的测试，最先版本可以在百度网盘或者onedrive下载：
CP4

CM5

@jugg 你用的那个版本的系统发出来。

@jugg 现在发布的ubuntu都是默认支持wayland和X11的。

@zensation
The firmware I tested is the latest version 20230613, and you can check if there is a problem with your power adapter causing the reboot.

@zensation
I tested the latest image of ubuntu22.04 and did not find the problem you described. As shown in the following figure, the PWR button is configured as suspend. The first press to enter sleep can be seen from the log information, and the second press to wake up the system.

@zensation I will confirm the CP4 machine and reply to you with the results later.

@zensation The latest images can support suspend operations, including ubuntu. Are you using CP4 or CM5

@jugg 需要把loader更新到最新。不是内核。

@zensation At present, when the machine enters suspend mode, all power supplies in the system will be turned off, and only the memory self refresh function will be retained. Currently, there is no support for exporting the memory data you described to the hard drive.

@zensation The latest kernel currently supports sleep mode. Please describe the specific operating scenarios required.

@blank Official document description: The pcie30x4 controller operates in EP mode and can be used in 4Lane mode or 2Lane mode using pcie30phy's port0. The 2lane in pcie30phy's port1 can be used as an RC in conjunction with other controllers.

• The SSD of the CM5 machine corresponds to the PCIE30 PORT0 interface

@阿里 都是独立的uart控制器，没有问题的。

@jugg 和22.04支持情况是一样的。

@零度灬救赎 刚才我在debian上测试，没有发现你描述的问题

@零度灬救赎 提供一下系统版本和串口端口号。测试一下尽快反馈。

@零度灬救赎 这个是应用层报错，确认一下内核有没有错误。可以先通过第三方工具（比如minicom）测试。

Adaptation situation:

• Open source GPU driver

• RKMPP video hardware decoding

• RK RGA Hardware acceleration

• RK NPU supports C++/Python interface calls

• Integrated Chromium web browser

• Integrate the Gstreamer Multimedia framework and support calling RKMPP

• Integrated FFMPEG Multimedia framework, supporting calling RKMPP

• RK ISP Application Layer Service Support

• Compatible with X11/WAYLAND display frame

@零度灬救赎 串口掉线什么意思。请描述一下具体情况。

@阿里 参考如下文档

@wuming 如果你是CM5-V11的机器，默认的loader是可以进入UMS模式的，短按一下rst按键，然后持续多次按pwr按键。

@wuming 那是系统进入MASKROM状态了！用官方的工具就可以看到maskrom设备。

@wuming 重启是按最左边的rst按键。loader按键会进入maskrom模式用于升级loader文件。按照文档操作。

@wuming 如下图所示正常进入UMS的log信息。

建议先吧loader更新到最新，老版本的不支持UMS方式烧录。参照如下文档：

@blank Sorry, there was an issue with the reply yesterday. Currently, only the M2 interface has EP functionality. The hardware operation is shown in the following figure (the clock directly skips the PLL chip), and the software can be modified as follows.

@wuming 确认loader是否已经升级到最新，机器和电脑通过USB线连接。重新上电，迅速多次按pwr按键。

@blank The PCIE ep mode requires modifications to the software and hardware, and the software dts configuration is sufficient. The hardware modification RC clock is directly connected to RK3568. The current board hardware configuration can only work in RC mode.

@jugg 这个显示还有问题，再处理，有结果会发补丁上来。

@零度灬救赎 目前2.4G最高，不支持再超到更高频率。强行超频可能会导致CPU物理损坏。建议增加散热措施，让CPU持续工作在高频即可。
