@大法师 建议尽快支持一下树莓派的HQ Camera，传感器型号是IMX477R，现在这款摄像头很火，可以匹配各种不同的镜头。IMX708支持自动对焦，是新出的产品。

@AugustRobot_Zou x谢谢，果然是如此。修改后两个语句初始化。可以用了。

@大法师 The latest ubuntu22.04 image can already support this camera.

20230210-ubuntu-22.04-preinstalled-desktop-arm64-coolpi.rar

V4L2-TEST can start the camera by operating the video11 node

@xws 部分适配器功率切换瞬间会掉电，会导致机器重启。

@xws
5V~24V 都可以的

@retroman Because the pi 4b box has no power key location, direct use will cause pwr key is stuck. In addition, the size of the DP output port is larger than Pi 4b, and the size of the metal radiator of PI4b is too far from the DP interface. 3D printing is the only option before the surrounding accessories of the cool pi come out.

How about OV9281, compatible with Raspberry PI 4B

@george 不错

Does Cool Pi 4B support parallel RGB like the Raspberry Pi 4b? I would love to put Cool Pi 4B board in the PiBoy DMG instead of the Raspberry Pi 4B.

@zensation check your firmware version, please use latest ubuntu22.04 for testing.

@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.

@harry-huang 谢谢 大哥。我们现在不是要烤火鸡。冬天了烤羊肉串呢。

@jack_admin 都是最近才开始接触的linux 下面的开发板编程。。。还没有弄过内核编译，我先学习下基础的东西，麻烦大佬有空了也帮忙看看，这个开发板接4G 应该还是有很多应用场景的，谢谢！
