我自己构建了AOSP Android 11 Sunfish，尝试使用fastboot将out图像闪存到手机中，整个构建和闪存过程都成功完成，但闪存完成后，设备卡在Pixel 4a的fastboot页面，并发布错误消息“Enter reason：没有有效的插槽可 Boot ”。
请注意，我已经使用Android项目官方网站上的工厂标准构建重新检查了整个 Flink 过程，一切顺利，设备开始工作，没有任何错误。
在所有的flash过程中，设备运行良好，自动引导进入fastboot模式，将product目录flash到正确的位置，最后一轮引导后，出现Google logo，然后设备出现前面描述的错误，整个flash日志如下：

我的设备已经解锁，所有的标准闪速过程都完成了，可能是我的out结构出了问题，所以编译aosp_sunfish-userdebug lunch后生成了以下镜像文件：
