循环输出上边的字符应该是陀螺仪检测不运去吧,开机只显示一个图片不能进安卓系统
您好：
您是自己做的底板吗，还是用的我们的，这个情况是一直就有呢还是后来出现的，镜像是用的标准的吗，请提供详细的信息 自己做的去掉一些接口的板,一直这样,程序是自带的,下载程序用OTG怎么下载?我电脑是XP的打开超级终端找不到串口,有没有祥细的步骤呀,没有下载过,只下载过手机固件 xs_wape 发表于 2017-8-10 09:11

您好：
1、我这里做过试验，去掉三轴加速度传感器，系统是可以启动的，所以应该是您去掉的其他接口影响了启动，4418的Android启动时的检测项主要有这么几个，显示、音频、网口、摄像头，您可以再改动底板测试一下
2、OTG烧写的话，建议参考用户手册，手册写的比较详细，OTG烧写需要安装驱动，如果安装不成功的话，建议使用SD卡烧写，比较稳定。
3、串口的话，可能是您的驱动没装好，装一个驱动软件刷一下驱动再试试，推荐驱动人生。
