RK3399移植富迪科技语音IC FM1388问题 - Firefly开源社区

各位大大先进们好
这次项目需要在RK3399J加上一个能侦测VAD和DOA的MIC ARRAY
选用的是FM1388这颗IC

在移植到ANDROID 7.1.2 BSP版本中遇到一些问题，
原厂提供的driver code中，
与系统主板是透过I2C控制，
但会透过SPI接口来从系统Firmware(system/etc/firmware)文件夹来下载
firmware 及 config file，
目前执行安装driver的时候遇到的问题LOG如下，

从system/etc/fimware读取配置文件及firmware一直读不到值，
这是跟文件夹档案权限或用户权力有关吗
请问要改的话要从哪边修改
请有经验的大大不吝赐教
谢谢各位
