IPQ4019 QSDK 下添加EC20链接网络，非内核添加GobiNet 驱动，ipk包方法

此种方法的好处是，openwrt的Linux内核过程文件是在build_dir目录下临时文件，这种编译就不会当心在执行make clean后内核在此修改的情况。

一、运行环境

1.qca-networking-2019-spf-11-0_qca_oem

2.IPQ4019

3.Linux4.4.60

4.USB2.0接口EC20PCIe拨号上网

二、移植步骤

1.首先内核Linux4.4.60无需增加EC20的关于USB 的PID VID等步骤；

 

2.内核添加USB网络配置选项：

总体来说是这几个驱动添加：

kmod-usb-serial kmod-usb-serial-option kmod-usb-serial-wwan usb-modeswitch
步骤：

1).顶层目录qsdk/ 下执行：

# make menuconfig
2).配置 kmod-usb-serial：

Kernel modules --->
USB Support --->
<*> kmod-usb-serial..................... Support for USB-to-Serial converters

3). 配置 kmod-usb-serial-option
Kernel modules --->
USB Support --->
<*> kmod-usb-serial-option................... Support for Option HSDPA modems
4). 配置 kmod-usb-serial-wwan
Kernel modules --->
USB Support --->
-*- kmod-usb-serial-wwan..................... Support for GSM and CDMA modems
5). 配置 kmod-usb-net
Kernel modules --->
USB Support --->
<*> kmod-usb-net............... Kernel modules for USB-to-Ethernet convertors
6). 配置 usb-modeswitch
Utilities --->
<*> usb-modeswitch................................ USB mode switching utility
7). 最后， 保存退出配置界面即可。

8).内核修改

# make kernel_menuconfig
Device Drivers --->
[*] USB support --->
<*> Support for Host-side USB
Device Drivers --->
[*] Network device support --->
<*> USB Network Adapters --->
<*> Multi-purpose USB Networking Framework
最后， 保存退出配置界面即可。

3.添加 GobiNet 驱动（非内核添加GobiNet 驱动，ipk方式），quectel_cm拨号
1).将GobiNet-drv.tar.gz https://download.csdn.net/download/weixin_41740391/12719339

解压至 qsdk/package/kernel/ 目录下

2).将 quectel_cm.tar.gz https://download.csdn.net/download/weixin_41740391/12719343

解压至 qsdk/package 目录下

3).顶层目录qsdk/ 下执行：

# make menuconfig

4).选择kmod-GobiNet-drv 驱动

Kernel modules  --->

Other modules  --->

<*> kmod-GobiNet-drv...................... GobiNet-drv-package-kmod-4g driver

5).选择quectel_cm 拨号

Base system  --->

<*> quectel_cm.............................. quectel_cm communication utility

6).保存退出，顶层qsdk/ 下编译

make -j4（4代表使用4线程编译，速度将提高，） V=s

过程中出现

NOP USB Transceiver Driver (NOP_USB_XCEIV) [N/m/y/?] n
AM335x USB PHY Driver (AM335X_PHY_USB) [N/m/y/?] n
GPIO based peripheral-only VBUS sensing 'transceiver' (USB_GPIO_VBUS) [N/m/y/?] n
NXP ISP1301 USB transceiver support (USB_ISP1301) [N/m/y/?] n

Qualcomm QUSB HS PHY driver support (USB_QCOM_QUSB_PHY) [N/m/y/?] n
Qualcomm QMP SS PHY support (USB_QCOM_QMP_PHY) [N/m/y/?] n
Generic ULPI Transceiver Driver (USB_ULPI) [N/y/?] n
*
* Hardware crypto devices
*
Hardware crypto devices (CRYPTO_HW) [Y/n/?] y
  Driver HIFN 795x crypto accelerator chips (CRYPTO_DEV_HIFN_795X) [N/m/y/?] n
  FIPS140-2 compliant build (FIPS_ENABLE) [N/y/?] n
  OTA Crypto module (CRYPTO_DEV_OTA_CRYPTO) [N/m/y/?] n
  QCEDEV Interface to CE module (CRYPTO_DEV_QCEDEV) [M/n/y/?] m
  Inline Crypto Module (CRYPTO_DEV_QCOM_ICE) [N/m/y/?] (NEW)

直接Enter 就可以了。

等待编译完成，如果是首次编译建议采用（make -j1 V=s）  -j4将会有某些编译顺序原因，会报错。

 

4.下载程序至target 板

set ipaddr 192.168.9.12
set serverip 192.168.9.10
ping ${serverip}

内核+dts+文件系统
tftpboot 0x84000000 ipq40xx-nornand-apps.img
imgaddr=0x84000000 && source $imgaddr:script

Flashing ubi:                           [ done ]  完成

5.查看驱动完成情况

root@OpenWrt:/# ls /dev/
出现这ttyUSBx qcqmiX 几个节点后，表示驱动正确安装并且模块正确链接启动。

 

6.建立网络链接

建立4G用网络节点 /etc/config/network
config interface '4G'
        option proto 'dhcp'
        option ifname 'eth2'
        option dns '114.114.114.114'

防火墙开启网络链接 /etc/config/firewall
config zone
        option name 'wan'
        list network 'wan'
        list network 'wan6'
        list network '4G'    #此处为添加部分
        option input 'REJECT'
        option output 'ACCEPT'
        option forward 'REJECT'
        option masq '1'   
        option mtu_fix '1'

未拨号前
root@OpenWrt:/# ifconfig
eth2      Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx
          UP BROADCAST NOARP MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

拨号：
root@OpenWrt:/# MobileNet &

拨号后：
root@OpenWrt:/# ifconfig
eth2      Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx 
          inet addr:10.xx.3.xxx  Bcast:10.xx.3.xxx  Mask:255.255.255.xxx
          inet6 addr: xxxx::e4f9:3fff:fe49:xxxx/64 Scope:Link

          TX packets:27 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:2681 (2.6 KiB)  TX bytes:3044 (2.9 KiB)
