RK3229_Android9.0_Box 4G模块EC200A调试

0、kernel修改

这部分完全可以参考Linux的移植：

6、遇到的问题

1、不断印下面这个

init: starting service 'ril-daemon'...

[ 444.744250] init: Service 'ril-daemon' (pid 1651) exited with status 1

[ 444.744308] init: Sending signal 9 to service 'ril-daemon' (pid 1651) process group...

[ 444.744453] libprocessgroup: Successfully killed process cgroup uid 0 pid 1651 in 0ms

解决方法就是更换ril库，换成ndk专用的

2、开机几十秒后进入recover模式

原因就是少加了<item>"mobile,0,0,0,-1,true"</item>这句，导致拨号应用异常崩溃后进入recover模式，完整应该加下面这段。

3、缺少apn

+PRODUCT_COPY_FILES += \
