    • RE: 请问coolpi 4b 电源输入功率多大合适,有电流保护吗?

      @night 机器TYPEC前端电源芯片耐压可以达到28V,极限可以到34V,所以你的适配器规格没有任何问题。
      开发板的电源部分一直是我们设计最优先考虑的方向,所以前端第一级电源花了很多功夫,考虑到用户各种各样适配器的规格,最终选择目前国内少数几家真正能做车规级别电源方案的厂家。尽量保证前端电源稳定可靠。

    • RE: Heatsync options

      @zensation The radiator can be matched with raspberry pi. A separate fan is OK. Normally, it is not necessary to add aluminum alloy fins on the CPU.

    • Coolpi uses UMS to update the system

      Coolpi supports UMS to update emmc firmware, as follows:

      1. Update the latest versions of loader and uboot images. You can also synchronize uboot code and compile it yourself.
      git clone https://github.com/yanyitech/coolpi-loader
      cd coolpi-loader
      ./build-uboot.sh cp4b
      
      1. Connect a dual A port USB cable to the computer and the upper USB 3.0 interface. Plug in the power and press the power button three times, and the machine will enter UMS mode.
        50e1fdf8-a822-415f-9ff2-6d52851735ee-image.png
      2. Use Etcher software to update the software.

    • RE: CM5 reboots for no reason.

      @etrin

      1. troubleshoot the power issue and try playing a network video to observe if there is a restart phenomenon.

      2. If you have a debug serial port board on hand, you can try monitoring the log information. And submit it to the community for our analysis.
