首先，要先获得技术支持
步骤一，先在USB模块上完成4G
步骤二，移植到PCIE座子上
磨刀不费砍材功，请先拿到技术文档支持，我的参考是：Quectel_Android_RIL_Driver_V3.3.62_master_beta(支持EC200A).tgz
主要文件：Quectel_Android_RIL_Driver_V3.3.62_master_beta(支持EC200A)\libquectel-ril\arm64-v8a\libreference-ril.so
主要文档：Quectel_Android_RIL_Driver_User_Guide_V2.0.pdf

PCIE原理图部分
调通USB转接小板之后，直接接在PCIE座子上就有信号出现了

Bus 001 Device 003: ID 25a7:fa61其中，ID 2c7c:0125就是我们的无线网卡EC20,如果没有，请检查硬件电路。
2.使用 ls -l dev/ttyUSB* 查看是否有节点和是否有权限（没有节点查驱动添加）
2|console:/ # ls -l dev/ttyUSB*

push 库进去测试

一般分为驱动问题（查节点生成）
二般就是库（查看是否更新到，查看logcat和push，检查加载的路径的库是否是这个库）

问题处理：没接4G模块直接打印到卡死
重复打印'android.hardware.radio@1.1::IRadio/slot1'
