    • RE: Would Cool Pi provide Batocera, Retropie, Lakka, Recalbox devs cool pi 4B boards for support?

      @retroman Thank you for your suggestion. We will discuss the time point of support internally.

    • RE: 能不能整理个完整版的说明文档呀

      @花月 具体一些,需要哪部分?因为本身linux系统相当庞大,基础的操作文档网络上的资料可能更系统一些。如果针对某些特定模块可以提出来。

      @tscmga 在你自己做的这个板子上面把HPD信号的驱动能力增强试试。极限情况下可以直接接5V.
      下面这款我们有测试过:

    • RE: 买的lcd屏幕 hdmi的在orangepi里有显示。但是在你们这个板子上黑屏

      @tscmga 这种非标设备暂时没有很好的办法兼容,会导致故此失比,我们之前有测试一款7寸的HDMI+USB触摸的是可以正常使用的,晚一点发链接给你。

    • 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。

      @zensation If this is the case, it means that the image you are using is incorrect, or it is not successfully created.

    • 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 4b with Ubuntu22 running panfrost gpu driver performance testing

      CPU

      测试方法:

      机器没有识别到这个HDMI设备。可能是接口或者分辨率非标准导致。
