      @勤奋者
      我们的ubuntu镜像不用考虑这个文件。若使用这个工具,请注意使用专用镜像目录

      建议后续使用U盘刷机

      @macthree 建议全新安装会更好,0303版本是纯净版系统,您也可以下载我们github ubuntu仓库构建纯净版本镜像

      @test 你的loader版本看起来比较早,升级loader试下。卡的分区表异常,格式化一次

      @jack_admin 那就没有问题了,只要优先从tf卡启动就行,我已经通过tf卡启动ubuntu22.04,然后通过dd命令将img写入到emmc中,并且启动成功。这样就再也不用把emmc从板子上取下来了,yeah!谢谢

      EMMC 读卡失败,可以直接插板子上,SD卡启动系统后识别出来吗
