我们正在使用 Raspberry Pi 3 Model B 和 64 Gb SD卡，并带有最新的 android物联网版本1.0.10 的闪存映像。 。连续运行Android设备6-7天，它会卡在启动页面上，仅显示其徽标。当我深入读取SD卡文件时，其中缺少 bootloader文件。
在引导过程中，我还读取了rpi的logcat。成功和不成功的启动日志猫之间有一些区别。
下面是一个重要的logcat，它在成功和失败引导方面有所不同，并且可能是整个问题的原因
成功启动附件：
[32m[ 0.000000] [0mInitializing cgroup subsys cpu/sys/android_power/request_state
成功日志链接
“ https://drive.google.com/open?id=1YIzF1Up-PXgqYKXiEifFtb_1otTK_pBd”
启动成功提示：
[32m[ 0.000000] [0mInitializing cgroup subsys cpu
logcat失败的链接
“ https://drive.google.com/open?id=1xcstYWo8DwAV3p8hS4GNwBYLSWPt2EnN”
这些是额外的日志猫，它们会以失败的启动方式出现：
