OpenHarmony3.1適配移遠(yuǎn)EC20模組4G上網(wǎng)功能
一、概述
通過閱讀本篇文檔，您將學(xué)習(xí)到如何適配移遠(yuǎn)EC20模組到OpenHarmony3.1（以下簡稱OHOS），并添加4G上網(wǎng)功能。
本篇文檔，使用硬件為大禹RK3568開發(fā)板。
開發(fā)板資料：https://gitee.com/openharmony/device_board_hihope/blob/master/rk3568/README_zh.md
軟件方案分為PPP和QMI兩種，請(qǐng)讀者自行選擇。
二、PPP方案
2.1.內(nèi)核添加對(duì)應(yīng)配置
CONFIG_PPP=y
CONFIG_PPP_ASYNC=y
CONFIG_PPP_SYNC_TTY=y
CONFIG_PPP_DEFLATE=y2.2.修改內(nèi)核驅(qū)動(dòng)源碼

注：因?yàn)镺HOS的/system分區(qū)為只讀，所以需要修改部分源碼將ppp配置文件路徑修改到/data下，這部分請(qǐng)讀者自行修改。
新建文件BUILD.gn，內(nèi)容如下：

group("ppp_copy") {

}2.4添加route
原始OHOS3.1中沒有route程序，造成ppp撥號(hào)成功后無法設(shè)置路由。
需要添加route軟件到toybox中，修改文件third_party/toybox/generated/config.h，內(nèi)容如下：
#ifdef WITH_SELINUX
# define CFG_ROUTE 1
# define USE_ROUTE(...) __VA_ARGS__
#else
# define CFG_ROUTE 1
# define USE_ROUTE(...) __VA_ARGS__2.5編譯配置
修改productdefine/common/products/rk3568.json，新增ppp：
"ppp:ppp":{}修改build/subsystem_config.json，新增ppp：
"ppp":{
"path": "third_party/ppp",
"name": "ppp"
},修改文件build/config/compiler/BUILD.gn：
treat_warnings_as_errors = false注：這里因?yàn)闊o需遵守編碼規(guī)范，故取消該設(shè)置。
2.6啟動(dòng)配置
修改文件base/startup/init_lite/services/etc/init.cfg。
新增jobs：
{
"name" : "services:pppd_service",
"cmds" : [
"mkdir /data/ppp",
"mkdir /data/ppp/var",
"mkdir /data/ppp/var/lock",
"mkdir /data/ppp/var/run",

系統(tǒng)啟動(dòng)后，自動(dòng)啟動(dòng)pppd進(jìn)行撥號(hào)，成功效果如下：
三、QMI方案
3.1內(nèi)核添加對(duì)應(yīng)配置
CONFIG_USB_NET_QMI_WWAN=y
CONFIG_USB_WDM=y3.2修改內(nèi)核代碼
拷貝移遠(yuǎn)提供的qmi_wwan_q.c源碼到drivers/net/usb/目錄。
修改drivers/net/usb/Makefile，內(nèi)容如下：
obj-${CONFIG_USB_NET_QMI_WWAN} += qmi_wwan_q.o
obj-${CONFIG_USB_NET_QMI_WWAN} += qmi_wwan.o3.3添加quectel-cm軟件
該軟件源碼由移遠(yuǎn)提供。
新建BUILD.gn，內(nèi)容如下：
import("http://build/ohos.gni")
group("quectel-cm-group") {
deps = [
":quectel-CM",
# ":quectel-qmi-proxy",
# ":quectel-mbim-proxy",
# ":quectel-atc-proxy",
":quectel-script"
]
}
ohos_prebuilt_etc("quectel-script") {
# relative_install_dir = "quectel"
source = "default.script"
part_name = "quectel"
module_install_dir = "quectel"
subsystem_name = "quectel"

defines = [

include_dirs = [

install_enable = true
part_name = "quectel"
subsystem_name = "quectel"
install_images = [

"updater",
]
}3.4啟動(dòng)配置
修改文件base/startup/init_lite/services/etc/init.cfg。文章來源：http://www.zghlxwxcb.cn/news/detail-737484.html
添加trigger，用以啟動(dòng)軟件：文章來源地址http://www.zghlxwxcb.cn/news/detail-737484.html
