1、CM5 EVB mipi dsi/eDP 支持哪些屏幕可以列个清单吗？兼容树莓派的接口(看原理图好像不一样)？
%(#eb1e1e)[这个接口和树莓派是不一样的，我们有做转接排线，可以兼容树莓派的sensor。]
2、想确认下现在CSI接口 IMX219(树莓派接口相机)在该板子上的适配情况？
%(#ea1a1a)[IMX219目前是可以支持的]
3、pcie 3.0 x4目前兼容哪些外设方便总结下不
%(#ef1f1f)[可以支持通用的PCIE设备，比如网卡 SATA扩展板 WIFI等，一般X86的ubuntu版本可以支持的外设都可以支持。]
4、发现cm5 evb 目前还没有android相关的SDK 开发包是开发组有碰到什么问题吗？有没有release的一个计划表？
%(#ec2222)[android版本可以参考CP4的源码自己更换DTS即可，这个建议用户自己实现。]

@阿里
wiki上有原理图和PCB也有标识第一脚位置，数一下就可以确定了。

@AugustRobot_Zou
可以，但是比较麻烦，需要改loader uboot kernel，现在扩展口上面串口不够用吗？

@igorp
I'm very glad you could provide help. Thank you.

@wangyx
参考如下文档有格式和对齐要求：

@S199pWa1k9r
Thank you for your suggestion. The main reason for choosing this shell is due to structural limitations. As our machine is designed with a core board and bottom board, the overall height will be higher than that of the single board method. At present, the metal shells on the market cannot meet the structural requirements.
We have conducted an evaluation on the heat dissipation, and the current heat dissipation method is to add graphene to the copper skin on the back. The temperature rise during normal video playback can be controlled to around 30 degrees Celsius.

@jugg 升级uboot需要进入loader模式或者maskrom模式，不是UMS

@veryy 把内核更新到最新版本。提供一下dmesg信息。

@qys2022 没有反。

@jugg 这个应该是系统自带的，网上找一下如何关闭。

Refer to the following documents：

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

@etrin

1. troubleshoot the power issue and try playing a network video to observe if there is a restart phenomenon.

2. If you have a debug serial port board on hand, you can try monitoring the log information. And submit it to the community for our analysis.

@qys2022 不使用PCIE3.0可以不用。

@fetsch Burn in the same way as other images, such as using an etcher.

@Orion 参数如下帖子处理，增加规则文件
