本文以飛凌嵌入式OKMX6ULL-S開發(fā)板為基礎(chǔ)講解，其它板卡請(qǐng)參考使用，本文主要講解了iMX6ULL 網(wǎng)絡(luò)功能的測(cè)試，分為無線網(wǎng)絡(luò)測(cè)試以及有線網(wǎng)絡(luò)測(cè)試，通過本文您可以快速了解飛凌iMX6ULL開發(fā)板網(wǎng)絡(luò)測(cè)試的全過程。
一、有線網(wǎng)絡(luò)測(cè)試
1、基本命令測(cè)試
每個(gè)開發(fā)板的網(wǎng)絡(luò)使用環(huán)境未必相同，本節(jié)測(cè)試示例中，網(wǎng)絡(luò)環(huán)境如下。實(shí)際使用中，請(qǐng)按照實(shí)際網(wǎng)絡(luò)環(huán)境自行進(jìn)行配置。

軟件設(shè)備 |

NET1 |
eth1 |

NET2 |
eth0 |
OKMX6ULL-C有eth0、eth1兩路網(wǎng)卡。開機(jī)已設(shè)置默認(rèn)eth0、eth1自動(dòng)分配IP。如果修改IP請(qǐng)修改/etc/network/interfaces。
注意：eth1與eth0不能用于同一個(gè)局域網(wǎng)。
下面以eth0為例進(jìn)行命令說明。
1.1、在Linux系統(tǒng)下，使用ifconfig命令可以顯示或配置網(wǎng)絡(luò)設(shè)備，使用ethtool查詢及設(shè)置網(wǎng)卡參數(shù)。
1.2、設(shè)置IP地址 ，查看當(dāng)前網(wǎng)卡詳情：
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、動(dòng)態(tài)分配IP地址
如果您的開發(fā)板與路由器連接，且路由器支持DHCP自動(dòng)IP地址分配可以在超級(jí)終端里面輸入命令：
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
用來動(dòng)態(tài)獲取IP地址，“-i” 參數(shù)用來指定網(wǎng)卡名稱，飛凌iMX6ULL開發(fā)板有線網(wǎng)絡(luò)的網(wǎng)卡名稱為eth0。
/etc/resolv.conf文件中有dns服務(wù)器信息會(huì)被自動(dòng)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中根據(jù)uid設(shè)置MAC地址，如果需要請(qǐng)?zhí)砑拥介_機(jī)自啟動(dòng)腳本中。
1.5、設(shè)置子網(wǎng)掩碼：
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、設(shè)置廣播地址
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/刪除默認(rèn)網(wǎng)關(guān)
添加默認(rèn)網(wǎng)關(guān)：
root@fl-imx6ull:~#route add default gw 192.168.20.1
刪除默認(rèn)網(wǎng)關(guān)：
root@fl-imx6ull:~#route del default gw 192.168.20.1
1.8、關(guān)閉開啟網(wǎng)卡
關(guān)閉eth0網(wǎng)卡：
root@fl-imx6ull:~#ifconfig eth0 down
開啟eth0網(wǎng)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服務(wù)
2.1、設(shè)置root用戶密碼，這里設(shè)置為forlinx，輸入密碼沒有回顯，串口終端無法看到輸入內(nèi)容。
root@imx6ullevk:~# passwd root New password: Re-enter new password:
2.2、然后配置開發(fā)板ip地址，保證和電腦通信正常。
root@imx6ullevk:~#ifconfig eth0 192.168.2.207 root@imx6ullevk:~#ping 192.168.2.135 -c 3
2.3、電腦使用FileZilla連接iMX6ULL開發(fā)板。
2.3.1. 點(diǎn)擊文件，站點(diǎn)管理器：
2.3.2. 創(chuàng)建“新站點(diǎn)”，主機(jī)輸入開發(fā)板IP，加密方式選擇只是用明文FTP，登陸類型選擇正常，用戶和密碼為開發(fā)板的用戶和密碼，點(diǎn)擊“連接”。
3、SSH登錄測(cè)試
以太網(wǎng)相關(guān)服務(wù)測(cè)試之前，確保已經(jīng)設(shè)置好IP。設(shè)置IP請(qǐng)參考以太網(wǎng)驅(qū)動(dòng)測(cè)試部分。
配置信息：
開發(fā)板ip：192.168.2.85
Linux主機(jī)地址：192.168.2.149
Windows主機(jī)地址：192.168.2.12
3.1、測(cè)試由linux主機(jī)通過ssh訪問開發(fā)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. RSA key fingerprint is 25:57:00:82:72:8f:09:8e:2d:b9:9b:41:e5:d6:06:bb. 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、測(cè)試由Windows主機(jī)通過cmd.exe或者Cmder訪問開發(fā)板：
$ ssh root@192.168.2.85 root@fl-imx6ull:~#
3.3、由iMX6ULL開發(fā)板訪問linux主機(jī)
root@fl-imx6ull:~#dbclient zs@192.168.2.149 Host '192.168.2.149' is not in the trusted hosts file. (ecdsa-sha2-nistp256 fingerprint md5 93:ff:74:8a:ed:ba:fd:21:39:d9:87:93:ad:9e:19:6f) Do you want to continue connecting?

New release '16.04.6 LTS' available. Run 'do-release-upgrade' to upgrade to it. Last login: Mon Mar 23 12:50:22 2020 from 192.168.2.87
4、USB轉(zhuǎn)網(wǎng)絡(luò)測(cè)試
4.1、將USB轉(zhuǎn)以太網(wǎng)插入U(xiǎn)SB host接口，識(shí)別信息如下：
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
4.2、測(cè)試方法參考以太網(wǎng)驅(qū)動(dòng)測(cè)試章節(jié)。
二、無線網(wǎng)絡(luò)測(cè)試

2.3、連接成功之后，ping百度測(cè)試：
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 64 bytes from 220.181.38.150: seq=1 ttl=53 time=71.086 ms 64 bytes from 220.181.38.150: seq=2 ttl=53 time=57.385 ms 64 bytes from 220.181.38.150: seq=3 ttl=53 time=71.033 ms --- www.baidu.com ping statistics --- 4 packets transmitted, 4 packets received, 0% packet loss round-trip min/avg/max = 57.385/64.738/71.086 ms
2.4、斷網(wǎng)與復(fù)位指令測(cè)試：
root@fl-imx6ull:/forlinx/shell#echo "AT^NDISDUP=1,0"> /dev/ttyUSB2
復(fù)位重啟模塊：
root@fl-imx6ull:/forlinx/shell#echo "AT^RESET "> /dev/ttyUSB2
2.5、更換SIM卡需要更換me909.sh中相應(yīng)的APN：
中國移動(dòng)：
echo "AT^NDISDUP=1,1,\"cmnet\""> /dev/ttyUSB2
中國聯(lián)通：
echo "AT^NDISDUP=1,1,\"3gnet\""> /dev/ttyUSB2
中國電信（本文使用）：
echo "AT^NDISDUP=1,1,\"ctnet\""> /dev/ttyUSB2
3、GPRS模塊測(cè)試
GPRS模塊與開發(fā)板之間采用串口連接，客戶可以使用飛凌公司自產(chǎn)的GPRS模塊，也可以使用自己購買的串口GPRS模塊。
1）在確保模塊和開發(fā)板串口UART3連接、上電OK情況下， 啟動(dòng)開發(fā)板子，進(jìn)入命令行終端輸入如下命令。

2）連接成功可以嘗試ping一下www.alphatocol.com
root@fl-imx6ull:~#ping www.alphatocol.com PING www.alphatocol.com (39.156.66.18): 56 data bytes 64 bytes from 39.156.66.18: seq=0 ttl=51 time=315.605 ms 64 bytes from 39.156.66.18: seq=1 ttl=51 time=732.351 ms 64 bytes from 39.156.66.18: seq=2 ttl=51 time=234.874 ms 64 bytes from 39.156.66.18: seq=3 ttl=51 time=2990.813 ms 64 bytes from 39.156.66.18: seq=4 ttl=51 time=2110.219 ms 64 bytes from 39.156.66.18: seq=5 ttl=51 time=1151.022 ms 64 bytes from 39.156.66.18: seq=6 ttl=51 time=450.403 ms 64 bytes from 39.156.66.18: seq=7 ttl=51 time=4650.867 ms 64 bytes from 39.156.66.18: seq=8 ttl=51 time=3747.240 ms 64 bytes from 39.156.66.18: seq=9 ttl=51 time=2866.635 ms 64 bytes from 39.156.66.18: seq=10 ttl=51 time=1986.155 ms 64 bytes from 39.156.66.18: seq=11 ttl=51 time=1087.178 ms 64 bytes from 39.156.66.18: seq=12 ttl=51 time=368.113 ms --- www.alphatocol.com ping statistics --- 13 packets transmitted, 13 packets received, 0% packet loss round-trip min/avg/max = 234.874/1745.498/4650.867 ms
注意： 假如ping命令不通，可能是之前測(cè)試以太網(wǎng)或無線網(wǎng)絡(luò)接口時(shí)的一些配置的影響，此時(shí)需要先執(zhí)行以下命令再測(cè)試模塊：
