OTG烧写系统失败

IMX6Q    1G版本过程如图：先是能识别到HID，烧写一部分后就显示无设备连接
烧写过程中打印信息

您那显示无设备连接是在烧写工具的什么时候，请把烧写卡住的时候的截图发一下，还有卡住时候的串口打印信息，我们这里帮您分析一下

点击开始后，win10系统每隔几秒出现设备接入提示 叮咚 声。
烧写过程中MFG显示信息一直在加载内核、加载设备树、无设备连接中循环
串口一直在重复打印这段信息

您现在是烧写linux4.1.15系统时，烧写过程中卡死是吗，烧写工具有没有做什么修改，您把附件里的设备树文件拷到  
USB烧写工具\mfgtools\Profiles\Linux\OS Firmware\firmware，试一试

xihua22

所有东西无任何改变，现在我尝试用SD卡烧写也不行，一用SD卡串口就没有调试信息打印，而且做好的卡里面和你拷贝的附件一样有 6dl 和6q两份设备树文件

我换成linux3.几在win7系统里面烧写成功了，就是那个飞思卡尔登录密码是啥啊，手册上没有
