是的U盘相当于硬盘，机器会优先从U盘启动。不需要做其它操作。制作U盘镜像之前建议先格式化一下U盘。

@mxpfeng 可以仿照这个，我理解5b的串口配置应该都差不多。

然后这种串口转USB的线淘宝上随便两三块钱买一个就好： 【淘宝】https://m.tb.cn/h.g2Q4mDj?tk=K3ZoWF1EmbK CZ3452 「黑PL2303HX USB转TTL RS232模块升级 USB转串口下载线中九刷机线」

老哥你好，请问你们的自制底板进展怎么样了呢？
我最近也在为CM5设计底板，不知道这个难度怎么样呢？方便邮箱交流吗？

We have plans to push the machine to the Armbian main line, but some business issues have not been resolved yet. We will notify you as soon as we enter the exhibition.
We will release the CM5 laptop version of Ubuntu 24.04 soon.
Thank you for your support.

@george
好的

@ytfycy
感觉还是配置问题导致的，直接刷我们发布的镜像有没有问题？

@樱月樱诗 USB接的哪一个口？应该是接上层USB3.0接口。

@Rock
The current human-computer interaction interface of uboot is not yet perfect. We are trying to do this and will notify you of the version launch as soon as possible. Thank you for your support.

@george Thank you!

@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。

@george
我所有的内核编译后更新 都是按照下面的步骤来的
5c151d27-6113-4c02-8d52-22e809e95cfe-image.png
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。
