      单独拿一个U盘,使用refuse工具,将udisk install专用目录下的镜像刷入U盘。

      将做好的U盘插入4B主板USB3端口(下面一个),插上TF卡,上电开机。

      如果有接HDMI显示器,可以查看安装过程(全自动安装),安装结束提示拔出U盘。

      按power按键开机,启动进入安卓系统。

      @jugg 还是以CM5为主,现在研发都投入到CM5定制化产品和软件维护。暂时没有计划开发新的核心板。

      @test 3588 8K视频解码是有部分限制,目前ubuntu22.04使用GST可以比较流畅播放。其它系统版本暂时不行。这里不是解码的问题,是显示的数据格式转换问题。如果开发8K视频类应用建议直接使用ubuntu22.04或者android。

      @jugg 你试下不改多指配置,编译内核再更新有无报错,能自行改内核是最好的

      @AugustRobot_Zou said in How to upgrade the boot loader of coolpi 4b?:

      Since I upgraded my PC to Win11, the RKDevTool always cannot find the device of coolpi-4b.
      Does the RKDevTool support Win11?
      Or could I upgrade the boot loader of coolpi-4b in ubuntu environment?

      https://www.cool-pi.com/topic/47/coolpi-4b-bootloader命令行升级方法

      用这个办法升级成功,避开RKDevTool 在win11驱动问题
