IPQ4019 QSDK 下添加RM500Q 5G 驱动 qmi拨号链接网络 配置 IPK包方法

拿到的移远的拨号软件驱动只用qmi方式，GobiNet 似乎没有。

一、运行环境

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

2.IPQ4019

3.Linux4.4.60

4.USB3.0接口 RM500Q qmi拨号上网

二、移植步骤

1.首先内核Linux4.4.60需要添加的关于RM500Q USB 的PID VID等步骤；

在此文件中 qsdk/build_dir/target-arm_cortex-a7_musl-1.1.16_eabi/linux-ipq_ipq40xx/linux-4.4.60/drivers/usb/serial/option.c 做如下修改。

 240 #define QUECTEL_VENDOR_ID                       0x2c7c
 241 /* These Quectel products use Quectel's vendor ID */
 242 #define QUECTEL_PRODUCT_EC21                    0x0121
 243 #define QUECTEL_PRODUCT_EC25                    0x0125
 244 #define QUECTEL_PRODUCT_RX500Q                  0x0800     //添加此处VID

。。。。。。。

 673 static const struct usb_device_id option_ids[] = {

。。。。。。。

1177         /* Quectel products using Quectel vendor ID */
1178         { USB_DEVICE(QUECTEL_VENDOR_ID, QUECTEL_PRODUCT_EC21),
1179           .driver_info = (kernel_ulong_t)&net_intf4_blacklist },
1180         { USB_DEVICE(QUECTEL_VENDOR_ID, QUECTEL_PRODUCT_EC25),
1181           .driver_info = (kernel_ulong_t)&net_intf4_blacklist },
1182         /**/
1183         { USB_DEVICE(QUECTEL_VENDOR_ID, QUECTEL_PRODUCT_RX500Q),//将VID添加此处
1184           .driver_info = (kernel_ulong_t)&net_intf4_blacklist },

 

2.内核添加USB网络配置选项，与EC20无太大差异：

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 kmod-usb-wdm
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

<*> kmod-usb-wdm.............................. USB Wireless Device Management   //qmi_wwan_q 依赖

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

<*>     QMI WWAN driver for Qualcomm MSM based 3G and LTE modems //qmi 要选择此项目，与GobiNet不同的地方
最后， 保存退出配置界面即可。

3.添加qmi 驱动，添加quectel-cm拨号

1).将qmi_wwan_q.tar.gz  https://download.csdn.net/download/weixin_41740391/12736911

解压至 qsdk/package/kernel/ 目录下

2).将 quectel_cm_5G.tar.gz  https://download.csdn.net/download/weixin_41740391/12736902

解压至 qsdk/package 目录下

3).顶层目录qsdk/ 下执行：

# make menuconfig

4).选择kmod-qmi_wwan_q 驱动

Kernel modules  --->

Other modules  --->

<*> kmod-qmi_wwan_q....................... Quectel Linux USB QMI WWAN Driver

5).选择quectel_cm 拨号

Utilities  --->

 <*> quectel-CM-5G............................ quectel-CM-5G app building test

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

4.下载程序至target 板

set ipaddr 192.168.9.xx
set serverip 192.168.9.xx
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

qmi拨号用节点重要，

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

拨号

7.增加DNS服务器解析IP地址功能

修改 /etc/config/network

config interface 'lan'
        option ifname 'eth1'
        option force_link '1'
        option type 'bridge'
        option proto 'static'
        option ipaddr '192.168.4.1'
        option netmask '255.255.255.0'
        option dns '114.114.114.114'    //DNS解析服务器
        option ip6assign '60'
        option multicast_querier '0'
        option igmp_snooping '0'

保存退出重启

root@OpenWrt:/# ping baidu.com
PING baidu.com (39.156.69.79): 56 data bytes
64 bytes from 39.156.69.79: seq=0 ttl=46 time=65.009 ms
64 bytes from 39.156.69.79: seq=1 ttl=46 time=57.406 ms
64 bytes from 39.156.69.79: seq=2 ttl=46 time=84.851 ms

4 packets transmitted, 4 packets received, 0% packet loss
round-trip min/avg/max = 57.406/72.008/84.851 ms

8.此时只用设备本体可以上网，LAN口和WiFi均无法上网，根据拨号部分显示内容

[08-21_06:14:01:018] should modify /etc/config/network as below?
[08-21_06:14:01:018] config interface wan
[08-21_06:14:01:018]    option ifname   rmnet_usb0.1
[08-21_06:14:01:018]    option proto    dhcp

所以修改 /etc/config/network

config interface 'wan'
        option ifname 'rmnet_usb0.1'
        option proto 'dhcp'

保存重启

此时即可用电脑链接LAN口，接通网络了。

9.注意此处用的SIM卡任然是4G的套餐服务，由于本人的5G套餐卡没到货，故4G先调通。
