@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：
https://www.cool-pi.com/topic/162/how-to-upgrade-the-boot-loader-of-coolpi-4b

@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。

@jugg 尽快确认回复你，之前没有和DSI一起，驱动部分可能会有部分修改。

@jugg 你现在想做的是3屏同显，1个MIPI 1个HDMI 1个MINIDP,我理解的有没有问题？

@jugg 显示框架改到X11测试，再登录界面选择：

@wuming 按照如下方法操作，格式化EMMC
1.按住中间的loader按键同时短按复位按键，机器就会进入maskrom模式，如下图所示：

2.选择loader文件，选择EMMC，点击download，等待完成以后点击Eraseall。即可完成EMMC擦除。

3.短按复位按键，快速按三次pwr按键，机器就会进入MSC模式

4.使用etcher选择固件和MSC设备烧录即可。

@wuming 下图如下固件测试，已经集成IMX219单摄的驱动和基础配置。

    add some wifi modules to cp4b

@jugg 请更新代码，已经提交了cp4b的配置。

@wuming 今天我会上传一个最新的镜像文件，默认支持IMX219单摄像头，你烧录以后再同步测试。先确认机器是否能正常进入MSC模式？

@wuming 上电开机，快速按三次pwr按键机器进入MSC模式，就可以使用etcher刷系统了。

@wuming 这个IMX219是有打开的。上层直接用QV4L2打开video11节点就好了。

@jugg 4b更新代码以后USB接口的WIFI模组都可以支持。

https://wiki.cool-pi.com/en/cm5/wifi-modules

Note: Models are continuously updated

@jugg 可以提交一下如下log信息，看IMX219有没有正常识别到。
