iMX6ULL 网络功能全检测

本文以飞凌嵌入式OKMX6ULL-S开发板为基础讲解,其它板卡请参考使用,本文主要讲解了iMX6ULL 网络功能的测试,分为无线网络测试以及有线网络测试,通过本文您可以快速了解飞凌iMX6ULL开发板网络测试的全过程。

一、有线网络测试

1、基本命令测试

每个开发板的网络使用环境未必相同,本节测试示例中,网络环境如下。实际使用中,请按照实际网络环境自行进行配置。

底板丝印

软件设备

NET1

eth1

NET2

eth0

OKMX6ULL-C有eth0、eth1两路网卡。开机已设置默认eth0、eth1自动分配IP。如果修改IP请修改/etc/network/interfaces。

注意:eth1与eth0不能用于同一个局域网。

下面以eth0为例进行命令说明。

1.1、在Linux系统下,使用ifconfig命令可以显示或配置网络设备,使用ethtool查询及设置网卡参数。

1.2、设置IP地址 ,查看当前网卡详情:

 

root@fl-imx6ull:~# ifconfig eth0 192.168.1.120
root@fl-imx6ull:~#ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 3A:D9:93:8E:A8:A4
          inet addr:192.168.1.120  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::38d9:93ff:fe8e:a8a4%2124311408/64 Scope:Link
          inet6 addr: fec0::38d9:93ff:fe8e:a8a4%2124311408/64 Scope:Site
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:28 errors:0 dropped:0 overruns:0 frame:0
          TX packets:63 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:11550 (11.2 KiB)  TX bytes:11579 (11.3 KiB)

 

1.3、动态分配IP地址

如果您的开发板与路由器连接,且路由器支持DHCP自动IP地址分配可以在超级终端里面输入命令:

 

root@fl-imx6ull:~#udhcpc -i eth0
udhcpc (v1.24.1) started
Sending discover...
Sending select for 192.168.20.101...
Lease of 192.168.20.101 obtained, lease time 86400
/etc/udhcpc.d/50default: Adding DNS 222.222.222.222

 

用来动态获取IP地址,“-i” 参数用来指定网卡名称,飞凌iMX6ULL开发板有线网络的网卡名称为eth0。

/etc/resolv.conf文件中有dns服务器信息会被自动添加。

1.4、修改mac地址:

 

root@fl-imx6ull:~#ifconfig eth0 hw ether 00:00:00:00:00:01
root@fl-imx6ull:~#ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:00:00:00:00:01
          inet addr:192.168.20.101  Bcast:192.168.20.255  Mask:255.255.255.0
          inet6 addr: fec0::38d9:93ff:fe8e:a8a4%2128292720/64 Scope:Site
          inet6 addr: fec0::200:ff:fe00:1%2128292720/64 Scope:Site
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:85 errors:0 dropped:0 overruns:0 frame:0
          TX packets:118 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:22942 (22.4 KiB)  TX bytes:22259 (21.7 KiB)

 

另外在/forlinx/shell/mac.sh中根据uid设置MAC地址,如果需要请添加到开机自启动脚本中。

1.5、设置子网掩码:

 

root@fl-imx6ull:~#ifconfig eth0 netmask 255.255.255.0
root@fl-imx6ull:~#ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:00:00:00:00:01
          inet addr:192.168.20.101  Bcast:192.168.20.255  Mask:255.255.255.0
          inet6 addr: fec0::38d9:93ff:fe8e:a8a4%2128915312/64 Scope:Site
          inet6 addr: fec0::200:ff:fe00:1%2128915312/64 Scope:Site
         UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:107 errors:0 dropped:0 overruns:0 frame:0
          TX packets:118 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:25700 (25.0 KiB)  TX bytes:22259 (21.7 KiB)

 

1.6、设置广播地址

 

root@fl-imx6ull:~#ifconfig eth0 broadcast 192.168.20.120
root@fl-imx6ull:~#ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:00:00:00:00:01
          inet addr:192.168.20.101  Bcast:192.168.20.120  Mask:255.255.255.0
          inet6 addr: fec0::38d9:93ff:fe8e:a8a4%2123332464/64 Scope:Site
          inet6 addr: fec0::200:ff:fe00:1%2123332464/64 Scope:Site
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:111 errors:0 dropped:0 overruns:0 frame:0
          TX packets:132 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:26130 (25.5 KiB)  TX bytes:25947 (25.3 KiB)

 

1.7、添加/删除默认网关

添加默认网关:

 

root@fl-imx6ull:~#route add default gw 192.168.20.1

 

删除默认网关:

 

root@fl-imx6ull:~#route del default gw 192.168.20.1

 

1.8、关闭开启网卡

关闭eth0网卡:

 

root@fl-imx6ull:~#ifconfig eth0 down

 

开启eth0网卡:

 

root@fl-imx6ull:~#ifconfig eth0 up
fec 20b4000.ethernet eth0: Freescale FEC PHY driver [Micrel KSZ8081 or KSZ8091] (mii_bus:phy_addr=20b4000.ethernet:01, irq=-1)
root@fl-imx6ull:~# fec 20b4000.ethernet eth0: Link is Up - 100Mbps/Full - flow control rx/tx

 

2、 FTP服务

2.1、设置root用户密码,这里设置为forlinx,输入密码没有回显,串口终端无法看到输入内容。

 

root@imx6ullevk:~# passwd root
New password:
Re-enter new password:

2.2、然后配置开发板ip地址,保证和电脑通信正常。

 

root@imx6ullevk:~#ifconfig eth0 192.168.2.207
root@imx6ullevk:~#ping 192.168.2.135 -c 3

2.3、电脑使用FileZilla连接iMX6ULL开发板。 

2.3.1. 点击文件,站点管理器:

 

iMX6ULL 网络功能全检测iMX6ULL 网络功能全检测

2.3.2. 创建“新站点”,主机输入开发板IP,加密方式选择只是用明文FTP,登陆类型选择正常,用户和密码为开发板的用户和密码,点击“连接”。

3、SSH登录测试

以太网相关服务测试之前,确保已经设置好IP。设置IP请参考以太网驱动测试部分。

配置信息:

开发板ip:192.168.2.85

Linux主机地址:192.168.2.149

Windows主机地址:192.168.2.12

3.1、测试由linux主机通过ssh访问开发板

 

zs@developer-RH2485-V2:~$ssh root@192.168.2.85
The authenticity of host '192.168.2.85 (192.168.2.85)' can't be established.

Are you sure you want to continue connecting (yes/no)? y
Please type 'yes' or 'no': yes
Warning: Permanently added '192.168.2.85' (RSA) to the list of known hosts.

 

3.2、测试由Windows主机通过cmd.exe或者Cmder访问开发板:

 

$  ssh root@192.168.2.85
root@fl-imx6ull:~#

3.3、由iMX6ULL开发板访问linux主机

root@fl-imx6ull:~#dbclient zs@192.168.2.149
Host '192.168.2.149' is not in the trusted hosts file.

4、USB转网络测试

4.1、将USB转以太网插入USB host接口,识别信息如下:

usb 1-1.3: new high-speed USB device number 8 using ci_hdrc

asix 1-1.3:1.0 eth2: register 'asix' at usb-ci_hdrc.1-1.3, ASIX AX88772B USB 2.0 Ethernet, 00:0e:c6:8f:9c:b7

IPv6: ADDRCONF(NETDEV_UP): eth2: link is not ready

2、板载WIFI的使用

如果开发板有板载的WIFI无线局域网卡,则焊接在评估板如图所示位置:

iMX6ULL 网络功能全检测iMX6ULL 网络功能全检测

步骤1:检查开发板是否已经焊接该模块,正确焊接如上图。连接上天线。

步骤2:开发板上电,启动Linux系统。

步骤3:进入测试脚本所在目录:

 

root@fl-imx6ull:~# cd /forlinx/shell

 

步骤4:执行测试脚本:

说明:-s表示wifi热点的名称;

-p表示密码,如果没有密码请输入-p NONE;

路由器采用wpa加密方式。

2、4G模块实现IE上网

2.1、将外扩USB 4G扩展板插入USB口,固定ME909s-821 PCIE封装4G模块,安装ipex天线座,买QQ靓号地图插入SIM卡,开机上电。

2.2、拨号上网

2.3、连接成功之后,ping百度测试:

 

root@fl-imx6ull:/forlinx/shell#ping www.baidu.com
PING www.baidu.com (220.181.38.150): 56 data bytes
64 bytes from 220.181.38.150: seq=0 ttl=53 time=59.450 ms

4 packets transmitted, 4 packets received, 0% packet loss
round-trip min/avg/max = 57.385/64.738/71.086 ms

 

2.4、断网与复位指令测试:

断开网络连接:

 

root@fl-imx6ull:/forlinx/shell#echo "AT^NDISDUP=1,0"> /dev/ttyUSB2

 

复位重启模块:

 

root@fl-imx6ull:/forlinx/shell#echo "AT^RESET "> /dev/ttyUSB2

 

2.5、更换SIM卡需要更换me909.sh中相应的APN:

中国移动:

 

echo "AT^NDISDUP=1,1,\"cmnet\""> /dev/ttyUSB2

 

中国联通:

 

echo "AT^NDISDUP=1,1,\"3gnet\""> /dev/ttyUSB2

 

中国电信(本文使用):

 

echo "AT^NDISDUP=1,1,\"ctnet\""> /dev/ttyUSB2

 

3、GPRS模块测试

GPRS模块与开发板之间采用串口连接,客户可以使用飞凌公司自产的GPRS模块,也可以使用自己购买的串口GPRS模块。

1)在确保模块和开发板串口UART3连接、上电OK情况下, 启动开发板子,进入命令行终端输入如下命令。

 

root@fl-imx6ull:~#cd /forlinx/shell/

2)连接成功可以尝试ping一下www.forlinx.com

注意: 假如ping命令不通,可能是之前测试以太网或无线网络接口时的一些配置的影响,此时需要先执行以下命令再测试模块:

 

root@imx6ulevk:~# ifconfig eth0 down
root@imx6ulevk:~#ifconfig wlan0 down
