      @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?

      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
      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

      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。

      @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。

      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.

      If you look at the serial log while installing Ubuntu, you will see a message saying that the emmc partition is broken, and it will stop.

      If you write ubuntu22.04 to emmc in UMS mode and reboot, serial data will appear as above.

      @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?

      After installing ubuntu 22.04 on the emmc of CM5 EVB, only the logo appears.

      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.

      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.
