        硬盘盒需要更新loader,且需要注意适配器供电功率

          @大法师 试了 usb插 硬盘盒子和 读卡器 还是只有京东卡可以启动,闪迪卡可以找到卡 但不能启动 ,重做和换镜像文件都没成功,0 2 1 3 6 8 7 9 trsv ln0 mon rx cdr lock timeout
          dp@fde50000 disconnected

          能找到卡,不能启动,可能与分区表有关,请参考

                  有些usb数据线是只供电的,不带数据信号。请确认一下

                        新的系统映像能跟新以下 树莓派摄像头和AP+sta的内核码,测试安装了ap+sta 的驱动后摄像头 ov56XX 不工作了。测试Create_ap无法运行,定位到摄像头和wifi 不能同时工作。
