@Rock
At present, the maximum version supported by coolpi laptop is 23.04. Ubuntu 24.04 has just been released a few days ago and adaptation will take some time. It is expected that a version will be released in May. Thank you for your support.

@masterli
性能肯定会有损失，从目前群控那边的情况来看，没什么太大问题。

@ytfycy
1.核心板可以支持PCIE3.0X4 ,目前对应的evb底板只有PCIE3.0X2.
2.笔记本的SSD接口是M2的PCIEX4接口。

我所有的内核编译后更新 都是按照下面的步骤来的

CM5、cp4都是这样操作的

内核编译后 都是整个out文件夹打包的

要安装libfdkaac-dev 编译的时候就会自动添加ext/fdkaac

@jugg
如果是TI的库仑计，而且内核有驱动，正常DTS配置一下就可以了。如果是linux内核没有的库仑计型号，就需要自己加驱动，相对麻烦一点。

1.目前硬件是强制SPI启动的，如下图硬件配置，如果要改为扫描启动方式，可以去掉R18的电阻。

2.目前使用的是rockchip的loader和uboot。github的uboot源码有包括SPL部分。用户可以自行修改，DDRBIN目前没有开放源码只有二进制文件。

@george 我可以在ubuntu系统上安装树莓派的工具Raspberry Pi Diagnostics吗

@Yannis
sudo apt update
sudo apt upgrade
按顺序执行

@jack_admin
我又重新刷了一下 能识别到AX200 但是不能作为AP使用

@阿里 said in 电源底板上电最大可以上多大需要多少安培:

有什么方法增大电源的功率吗

你换个功率更大的适配器就可以了，比如12V3A的。

@清客
有没有串口工具，提供一下启动日志。或者找个U盘，镜像做到U盘里边测试。TF卡制作之前最好格式化一下。

@jugg 核心板比较紧，稍微使点劲插好，锁好

@admin 这个问题之前在另外一款INTEL的相机上没有复现到现象。目前你用的这款暂时没有。

@george
我重新编译 换了内核 有没有关系

@alfek
Sorry, CM5-EVB is currently unable to directly test the VCC5V0_USB current. If you have some hands-on ability, you can try adding a 100 milliohm sampling resistor at the position shown in the diagram to determine the current by testing the voltage at both ends of the resistor.

@大法师
现在就是在CM5的安装盘里面改的
U盘我用来装WIn10都没问题

@etrin sudo mkfs.ext4 /dev/mmcblk0

@jack_admin The attached log records are all. Even if I reboot again, I only see the log with the same content. Is it possible to control the booting state from serial mode? Other boards can enter control mode using key values. What should I do with cm5?

@george I updated the OS by connecting to the top of the USB3.0 blue connector.

@george
这个是CM5的能更新开机logo的吗?

按照这上面的来 怎么我的编译不了

@jack_admin
刷机成功

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

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

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.

@george
4B csi摄像头的问题有结果了吗

@jugg 在浏览器测试是否可以放大缩小！用chromium。
