      @george 又接了一个USB麦克风 也不能录 提示同样的错误
      只能重启 重启后也只能录一次 第二次就不能录了
      后面又测试了一下 发现是因为在开机之前接了一个显示屏和一个HDMI显示器 开机之后再把HDMI拔掉之后再录音
      就出现上面的情况

      @大法师 said in 20221213-ubuntu-20.04-preinstalled-desktop-arm64看不到周边wifi列表、鼠标箭头看不到等现象:

      @bbsvs2000

      sudo dpkg -i coolpi-kernel_1.0.0_aarch64.deb sudo reboot

      deb包安装--增加驱动支持

      20230115-ubuntu-20.04-preinstall-server-arm64-coolpi
      一直识别不了CH340,usb转串口芯片。装了这个包就可以了

      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。

      @admin 这个问题之前在另外一款INTEL的相机上没有复现到现象。目前你用的这款暂时没有。

      @Momo-0 Thank for your reply.
      I think the point is pcie 3.0 /4.0
      maybe pcie 3.0 version nvme ssd should be okay.

      @mxpfeng 可以仿照这个,我理解5b的串口配置应该都差不多。
      https://cool-pi.com/topic/26/coolpi-4b-debug-console串口接线配置说明?_=1715909783162

      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」

      @george 终于可以了,把系统删减到14个G,就可以用U盘拷贝了,但是使用脚本的方法还是不可以,后面再研究了。谢谢解答👍
