      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。

      @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。

      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

      Pi4B使用realsense深度相机开机默认识别为USB2.0设备。重新插拔后才能识别为USB3.0设备。

      @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.

      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.
