准备工作
硬件
软路由（如j4125），需要支持minipcie
移远RM520N（M.2 KEY B接口）
M.2 KEY B转minipcie的转换模块
软件
安装PVE系统
移远RM520N官方提供的驱动和拨号软件
PVE使用RM520N
安装驱动
安装编译需要的工具
apt install make gcc pve-headers-`uname -r` dkms usb-modeswitch wpasupplicant net-tools安装官方驱动
使用WinSCP工具上传驱动**Quectel_Linux_Android_QMI_WWAN_Driver_V1.2.6.zip**到PVE中。
解压并进入目录，执行**make install**
root@pve:~/wwan/Quectel_Linux_Android_QMI_WWAN_Driver_V1.2.6# make install如果出现如下错误

将**u64_stats_fetch_begin_irq()** 替换为**u64_stats_fetch_begin()**。
将**u64_stats_fetch_retry_irq()** 替换为**u64_stats_fetch_retry()**。
如下所示：
拨号
编译quectel-CM
使用WinSCP将官方的拨号软件**Quectel_QConnectManager_Linux_V1.6.5.zip**上传到PVE中，解压并进入目录，执行**make**命令
root@pve:~/wwan/Quectel_QConnectManager_Linux_V1.6.5# make### 安装busybox
quectel-CM 调 用 busybox udhpc 获 取 IP 和 DNS ， busybox udhpc 调 用 脚 本 文 件/usr/share/udhcpc/default.script 为 Linux 开发板设置 IP、 DNS 和路由表。
防止安装busybox中报错，提前安装以下工具
root@pve:~# apt-get install libncurses5-dev从https://busybox.net 下载 busybox工具的源代码，解压并进入busybox目录，使用以下命令启用CONFIG_UDHCPC。
root@pve:~/busybox/busybox-1.36.1# make menuconfig勾选Networking Utilities ---> udhcpc，如图所示。
将脚本文件examples/udhcp/simple.script 复制并重命名到/usr/share/udhcpc/default.script。
执行make install命令安装busybox。
root@zy-pve:~/busybox/busybox-1.36.1# make install回到拨号软件目录，执行如下拨号命令获取IPV4和IPV6公网IP。
root@pve:~/wwan/Quectel_QConnectManager_Linux_V1.6.5# ./quectel-CM -4 -6 &使用ifconfig查看成功拨号后的效果
