Android 4G 模块添加 TV平台Mstar HISI


Android9.0 HIsi

Android 8.0Mstar

Android 4.4 Hisi

模块有方N720

首先根据模块方添加linux驱动 一般不会出现很大的问题

这个模块是USB 串口的更改option.c（路径一般为 kernel/drivers/usb/serial/option.c）具体以供应商手册为准。

后面的添加也是照搬

最主要一步 添加驱动hisi 有可能会打不开make kernel_menuconfig

直接把这个加到你对应板子的Deconfig就可以了

添加完这个就可以把kernel放到你的板子里了


可以看到usb设备节点

kernel就完全没问题了

要注意 kernel是不是打开了PPP一般来说用PPP比较多 也比较容易调试

接下来就是系统了 7.0以下直接在init.rc里面添加 然后更改下权限就可以了

Android 8.0以上

直接修改hardware/ril/rild/rild.rc

接下来也是 8.0以上添加服务

（大部分代码出自git log 为了方便粘贴只去掉+号 请自行缩进）

最重要一步 关掉SELinux 当然有的厂家选择不关掉

两种方法

1. bootargs 更改

2.适用于Android9.0

当然不关也没问题~~自己写权限文件 由于我们可以关掉 我就没去看

整个文档部分结束

这个地方加完可能大部分芯片可以

但是有的厂商！！！！！！！！！！！！！！！！

所有都关掉

基于9.0所有都关掉最全攻略

trySetupData for APN type default, reason: dataEnabled. Data disallowed, reasons: DATA_DISABLED 这个错误基本上就是没加ro.com.android.prov_mobiledata=true

附录：
安卓网络首选项修改如下参数：
    路径（因平台而异）：
    frameworks/base/telephony/java/com/android/internal/telephony/RILConstants.java
   
    安卓默认参数设置：
    int PREFERRED_NETWORK_MODE = TelephonyManager.getDefaultPreferredNetworkType(0, NETWORK_MODE_WCDMA_PREF);

    修改为：
    int PREFERRED_NETWORK_MODE = TelephonyManager.getDefaultPreferredNetworkType(0, NETWORK_MODE_LTE_GSM_WCDMA);

REQUEST_SET_PREFERRED_NETWORK_TYPE

/* NETWORK_MODE_* See ril.h RIL_REQUEST_SET_PREFERRED_NETWORK_TYPE */

下面是所需要编译的包不要问为什么 加就对了

上面基本上除了apn其它的模块商都会给 要注意自己的cpu架构 怎么看呢

我这个是32位的 当然一般64兼容32

还有一个地方要设置hisilicon/Hi3751V350/overlay/frameworks/base/core/res/res/values/config.xml(这个config一般厂商都会有overlay如果没有 就在frameworks相同的路径里面)

这个地方是设置网络优先级 如果没有mobile就会有问题

全部检查OK之后 应该就可以上网了ppp0就是模块的网卡

还有很多人出现PPP退出 查看/dev/ppp设备节点有没有 有的话强制chmod 777试一下 应该是可以上网 然后写到init.rc就可以了
