99元开源创客神器- NanoPi -来了！

快速入门

---

准备工作
要开启你的NanoPi新玩具，请先准备好以下硬件

• NanoPi主板
• microSD卡/TF卡: 最小系统需要64M
• microUSB线
• 一台运行Linux的电脑，需要联网

制作一张带运行系统的microSD卡
1) 将microSD插入Ubuntu的电脑，用以下命令查看你的SD卡设备名

复制代码 dmesg | tail

当dmesg输出类拟信息 sdc: sdc1 sdc2时，则表示SD卡对应的设备名为 /dev/sdc，也通过用命令cat /proc/partitions来查看。

2) 下载固件并制作microSD卡

复制代码 git clone [url]https://github.com/friendlyarm/sd-fuse_nanopi.git[/url] cd sd-fuse_nanopi su ./fusing.sh /dev/sdx

(注：/dev/sdx请替换为实际的SD卡设备文件名)

运行系统
将制作好的microSD卡插入NanoPi，使用microUSB线连接电脑，NanoPi会上电自动开机，看到板上的蓝色LED闪烁，这说明系统已经开始正常运行了。

通过microUSB登陆NanoPi
用microUSB线将NanoPi连接到电脑后，在电脑上敲入dmesg命令，看到以下输出信息表示连接成功：

复制代码 [12601.100339] usb 2-1.7: Product: FriendlyARM Gadget v2.4 [12601.100343] usb 2-1.7: Manufacturer: Linux 4.1.2-FriendlyARM with s3c-hsudc [12601.103192] cdc_acm 2-1.7:2.0: This device cannot do calls on its own. It is not a modem. [12601.103368] cdc_acm 2-1.7:2.0: ttyACM0: USB ACM device [12601.105300] cdc_ether 2-1.7:2.2 usb0: register 'cdc_ether' at usb-0000:00:1d.0-1.7, CDC Ethernet Device, 46:a1:e7:6d:5c:32

在电脑上输入ifconfig命令，可以看到多了一个usb0的网络设备，这时可以通过ssh到192.168.100.1这个地址来登录NanoPi:

复制代码 ssh root@192.168.100.1

在提示输入密码时，输入预设的密码fa，即可登入。

配置使用Wi-Fi
使用ssh连接NanoPi，输出以下命令配置WiFi：

复制代码 wpa_passphrase YourWiFiESSID 'YourWiFiPassword' >> /etc/wpa.conf wpa_cli -iwlan0 reconfigure

其中，YourWiFiESSID和YourWiFiPassword请替换成你要连接的无线AP名称和密码， 以后每次开机，都会自动连接该WiFi，你可以通过编辑 /etc/wpa.conf 调整无线AP的设置， 默认是通过dhcp的方式获得IP地址，如果你想更改成静态设置IP地址，可编辑 /usr/sbin/wpa_action，将其中的udhcpc调用改成使用ifconfig命令来设置。

扫描无线AP
用以下命令搜索周边的无线AP:

复制代码 wpa_cli -iwlan0 scan wpa_cli -iwlan0 scan_result

wifi有严重的问题。 iw dev wlan0 scan 连续执行一段时间15-30分钟就会出现。
