确认USB接口为上层的USB3.0接口？

@anernest
The currently debugged LCD models are shown in the attachment. The github code has been supported by default. The replacement steps are as follows:

1. Replace the LCD screen with a touchscreen model
2. Replace the ribbon cable
3. It is necessary to add a touch screen level conversion board

@enok71
George ppa provides ffmpeg source code and its patches, and can continue to develop on this code. We hope to support more formats. Especially in the coding part.

@enok71
The hardware acceleration software package currently defaults to using George PPA. We are currently researching a new branch and will release the results as soon as possible.

@enok71
Due to copyright issues with ffmpeg, only limited decoding support has been provided for ffmpeg Rockchip.

@jugg 在浏览器测试是否可以放大缩小！用chromium。

@阿里
这个应该是和显示框架有关，可以在驱动加打印看看。

@jugg
摄像头的问题会尽快确认回复。谢谢支持。

@银河铁道
修改DTS配置，然后把编译生成的dtb文件拷贝到boot分区重启即可。

@阿里
具体是什么情况。看log信息没有触摸屏的注册。

@jugg
请使用ubuntu22.04的镜像测试。

@阿里
下面这个配置去掉

@zehui
启动的流程是一样的，目前uboot的结构如下：

@阿里
可以尝试禁止掉HID-GENERIC这个驱动。

@阿里
从log看设备识别为两个设备，这个可能会有冲突。

@阿里
具体USB有没有报错，一般USB触摸是免驱的之前有测试过微雪7寸的USB触摸屏，可以正常使用。

@alfek
At present, CM5 is compatible with an 800 * 1280 LCD module, which will be launched soon. Of course, you can also adapt the module yourself, and we provide support.

@enok71
1.The touch screen is currently supported and requires replacement of the ribbon cable and LCD.
2.The TYPEC port charging function can be supported in future versions, which will involve modifications to the motherboard.
3.The backlight keyboard needs to be customized, and the motherboard already has integrated circuit interfaces.
4.Fingerprints can be extended using USB or SPI interfaces, NFC can also be extended through I2c interfaces, and the motherboard has reserved FPC connectors for expansion.

@jugg 使用如下命令测试

arecord -D hw:2,0 -d 10 -f cd -r 44100 -c 2 -t wav test.wav
aplay -D hw:2,0 test.wav

@阿里
显示框架改为X11可以同时输出的。

@阿里
下面这几款都有测试过，代码是可以兼容的，不需要修改。

如下图选30PIN反向

@阿里
这个是标准的30PIN edp接口。因为是通用接口，满足接口要求的都可以支持。

@阿里
机器进入UMS模式，电脑会识别到一个system-boot的盘符，然后把新生成的dtb文件拷贝进去，重启即可。

@阿里

@阿里 DTS中把PCIE3.0相关的配置disabled掉。

@qys2022 如下图所示DTS的对应属性改为disabled

@crazycatcoolpi
如下图所示机器进入MASKROM模式，然后加载loader和系统镜像，地址都是0X0000，loader选择SPI-NOR,系统镜像选择EMMC，然后勾选强制按地址写就可以了。

@enok71
Currently, both the official kernel for 6.1 and the mainline kernel for 6.7 are being adapted. Github has already pushed version 6.1, but currently only supports CM5-EVB. Modifications for other machines will be submitted as soon as possible. After the kernel version stabilizes, an updated distribution image will be released.

@anernest
Can you confirm if there are any issues with TYPEC or HDMI separately? I remember the resolution of the three screens should be consistent.

@sushruth
Just upgrade the kernel separately! You can use deb to upgrade or directly command to upgrade.
