我在使用 Android 模拟器时遇到问题。
我已经为android编译了ARM goldfish内核。并创建了一个 AVD(Android API 级别 18。使用 YAFFS2)，然后使用模拟器启动系统，如下所示。
./tools/emulator -kernel /home/daehee/kernel/goldfish/arch/arm/boot/zImage -verbose -show-kernel -avd test2
这很好用。内核工作正常，模拟器工作正常，一切都很好。
但是，如果我用我从 Android Framework 源代码编译的模拟器替换模拟器。内核挂载文件系统(YAFFS2)失败。
我认为这是因为金鱼 MTD 页面大小已更改...但我不知道如何修复它。有人可以告诉我这是怎么回事吗？
以下是我更改模拟器之前/之后的模拟器和内核日志消息。

最佳答案
我假设您是在 AOSP master 的基础上构建的？我们需要知道版本。
如果SELinuxFS挂载失败，则init无法加载selinux策略。这是一个 fatal error 。
调用链来自system/core/init/init.cpp 调用在external/libselinux/src/android.c 中定义的selinux_android_load_policy()。请参阅 init.cpp 中的代码 fragment :
if (selinux_android_load_policy() < 0) {
ERROR("failed to load policy: %s\n", strerror(errno));
security_failure();
}
可能要确保您的内核构建是正确的。确保内核支持 SELINUX。请参阅金鱼内核的这些相关补丁:
