imx6qp+SABRE Board 参考官方文档移植androidN 7.1.1失败

按照文档android_N7.1.1_1.0.0_docs 做了代码编译，下载，打印log显示

发现kernel没有编译selinuxfs，添加以下项
CONFIG_SECURITY_SELINUX=yCONFIG_SECURITY_NETWORK=y
CONFIG_SECURITY=y
CONFIG_AUDIT=y
CONFIG_NET=y
CONFIG_INET=y
CONFIG_LSM_MMAP_MIN_ADDR=32768
编译下载打印如下

查找发现system/sepolicy/Android.mk中定义policyvers=30，kernel代码中最大支持为29
我认为板子和代码都是官方的，应该顺利容易就跑起来，但是现在看到的log觉得差距还是比较大的

要看一下你的编译环境中需要安装的packages是否安装
