firefly-rk3399-Industry如何彻底关闭selinux

Reinhardt

我们在适配RIL时，有如下打印

其中提到selinux maybe set Enforcing mode
我们是指定了ttyUSB1作为AT命令口的，权限也是777.但仍报了这个问题。
请问是否有大神知道如何彻底关闭selinux

我用getenforce命令查了，显示是Permissive模式。但是在实际调用ttyUSB1时，
01-18 18:04:21.790 D/RILC    (  315): fd = 5
01-18 18:04:21.790 D/RILC    (  315): open device /dev/ttyUSB1 correctly

01-18 18:04:21.792 D/ATC     (  315): AT> ATE0Q0V1

01-18 18:04:22.500 E/ATC     (  315): warnning - moderm no response, retry ATE0Q0V1
这里显示Write to a channel which wasn't acked to be open，但是我open这个节点时的fd都拿到了，为什么还会报这个问题呢？是否还是selinux的问题呢？
