        @jugg 先确认安装U盘是否可用，备份U盘是否可用。用备份好的U盘，把backup目录文件拷贝到安装U盘install目录

          安装U盘和备份U盘都可以用
          刚做好的安装U盘是可以刷系统 就是安装镜像里面的系统
          备份u盘是可以备份系统 backup可以备份出系统
          但是把备份U盘中backup文件夹的内容 拷贝到安装u盘的install文件夹中
          安装U盘不能还原系统

              @jugg 只拷贝img文件和tar包。如果安装异常，发些log分析

                备份U盘的backup只生成了这些

                没有tar包

                  插了安装U盘 还是直接进系统了

                    @jugg 没识别到你插的U盘，直接启动emmc系统。你确认下U盘插的位置

                        你再试试，没道理备份能用，安装能用，还原也是安装的过程

                            除了刚刚做好的安装U盘能刷系统外
                            替换了install目录里面的文件 它就直接进系统了

                              @jugg 同一个U盘，断电重启，插U3下面一个或上面一个端口

                              starting USB...
Bus usb@fc880000: USB EHCI 1.00
scanning bus usb@fc880000 for devices... 1 USB Device(s) found
       scanning usb for storage devices... 0 Storage Device(s) found

                              观察能否扫描到存储设备

                                    你的U盘有几个，什么型号的，是概率识别？

                                      刚把U盘刷成安装盘 就能识别

                                      替换了install里面的文件就不行

                                      不过有时偶尔能识别 我试了几十次 好像就1次能识别 后面怎么试都不行

                                      插板子的系统能识别

                                          @jugg 你升级下最新的loader，再试下上下两个U3有没有改善。我们测试用闪迪/金士顿 U3 U盘，也试过部分移动硬盘，可以识别加载

                                            需要自己重新编译？
