一、4G移植：

1.  pid、vid添加:

　　drivers/usb/serial/option.c

 驱动里面已经默认有，这一步可以忽略.。

2.

        return urb;
 }

4.添加qmi_wwan_q.c(移远原厂提供)文件，makefile添加qmi_wwan_q.o（特别注意要放在qmi_wwan.o的前面）

diff --git a/drivers/net/usb/Makefile b/drivers/net/usb/Makefile

*实际调试发现，没有用这个驱动时候，有4G信号和图标出来，但是不能上网，替换完这个驱动就可以正常上网了。

5.添加cdc-wdm0节点：

调试过程看adb shell logcat -b radio,报错：

 按照报错提示，把path补丁加上：

diff --git a/system/core/init/devices.cpp b/system/core/init/devices.cpp
index ada1e28..812c60d 100755
 --- a/system/core/init/devices.cpp
 +++ b/system/core/init/devices.cpp
 @@ -407,6 +407,10 @@ void DeviceHandler::HandleDeviceEvent(const Uevent& uevent) {
          int device_id = uevent.minor % 128 + 1;
          devpath = StringPrintf("/dev/bus/usb/%03d/%03d", bus_id, device_id);
         }
 +#if 1 //add by quectel for mknod /dev/cdc-wdm0
 +       } else if (uevent.subsystem == "usbmisc" && !uevent.device_name.empty()) {

+#endif
      } else if (StartsWith(uevent.subsystem, "usb")) {
          // ignore other USB events
          return;

这时就会生产一个/dev/cdc-wdm0节点，还需要添加权限：

diff --git a/ueventd.rockchip.rc b/ueventd.rockchip.rc
index 9a6843c..0b1c30e 100755

移植完以上，开机log会有以下信息：

 

5.4g默认是关闭的，需要打开：

diff --git a/BoardConfig.mk b/BoardConfig.mk
index 41b34e1..d9a3e4e 100755

 BOARD_WIFI_SUPPORT ?= true
 
 #for rk 4g modem
-BOARD_HAS_RK_4G_MODEM ?= false

6.为了方便，直接用移远提供的库文件替换rk系统默认自带的：

　　device/rockchip/common/4g_modem/lib64/librk-ril.so

　　这个编译出来会拷贝到/vendor/lib64下

7.完成以上步骤，就可以正常上网，但设置里面关于4G网络的业务显示以及状态栏的信号图标都是没有的。

8.添加4G物联网卡APN

+  <apn carrier="中国电信物联网m2m" mcc="460" mnc="03" apn="CTNET" user="m2m" password="vnet.mobi" type="default" />
+  
 </apns>

9.没接4G模块时候，一直报错：

需要修改以下2点：

         }

 

二、GPS移植：

　　1.文件准备：

　　　　device\rockchip\common目录下文件夹quectel-gps，里面包含GPS需要的库文件gps.default.so、gps_cfg.inf(移远提供)

　　2.支持打开GPS：

device/rockchip/rk356x/BoardConfig.mk
wangmc@m5280:~/sata/rk3568-11.0-hhx/device/rockchip/rk356x$ git diff

　　3.修改device/rockchip/common/device.mk　

diff --git a/device.mk b/device.mk
index 782b0fd..6123734 100755
--- a/device.mk

diff --git a/compatibility_matrices/compatibility_matrix.5.xml b/compatibility_matrices/compatibility_matrix.5.xml

此时GPS移植就已经完毕，接下来就是测试。

5.apk测试数据如下：

 

 测试需要注意：

　　1.如果室内没有gps的信号放大器，需要把设备天下移到靠室外的窗户边

　　2.GPS天线尽量朝上对着天空，不要朝下

　　3.信号条件如果，时间需要等久一点，apk就会有数据出来
