CM5主板按一次reset键复位，右侧pwr键按3~5次，进入UMS模式；接双头TYPE-A USB线连接电脑与USB OTG端口（U3 蓝色上层），电脑打开etcher烧录软件，选择img镜像进行烧录。

-
@大法师：好像不行，按reset键是开机的时候，还是关机的时候，是一直按住再按pwr键，还是只按一次，就释放，再按pwr键
-
@wuming
如果是关机状态：
上电开机，短按3~5次pwr按键如果是开机状态：
按一次reset键，使系统复位，再短按3~5次pwr按键 -
@大法师 好像一直进不去，估计是手气比较差，难怪mj不行
-
@wuming
不着急，cpu加载也要时间。正常操作就好 -
@大法师 give up.等u盘刷机版出来吧。
-
-
@大法师绝对没有错
-
@wuming 确认loader有没有更新到最新，先连接USB到电脑，然后短按rst一次，然后按三次PWR按键，机器就会进入UMS模式。
-
@大法师 ：正常启动的log，按pwr键三次毫无反应

@wuming 确认loader是否已经升级到最新，机器和电脑通过USB线连接。重新上电，迅速多次按pwr按键。
-
@george 这个log是通过串口读出来的，usb口连接了也没有什么反应，系统直接进入桌面，按loader键重启系统就卡死，完全没有反应，串口log也打不出来
-
@wuming 如下图所示正常进入UMS的log信息。

@george 我的主板是cm5-v11，按loader键重启是卡死状态。串口不能打印任何log信息
-
@wuming 重启是按最左边的rst按键。loader按键会进入maskrom模式用于升级loader文件。按照文档操作。
-
@george 我就是先按住rst键不放，再按住loader键，然后先放开rst键，最后放开loader键，系统然后卡死，无任何反应
-
@wuming 那是系统进入MASKROM状态了！用官方的工具就可以看到maskrom设备。
-
@wuming 如果你是CM5-V11的机器，默认的loader是可以进入UMS模式的，短按一下rst按键，然后持续多次按pwr按键。
-
@george 按loader重启，没有发现设备
