SD卡测试
系统启动后将SD卡插入到Micro SD卡槽【J26】中,系统会自动将其挂载到/run/media目录下,在插入SD卡的同时,在系统终端会打印出SD卡相关信息:
[ 418.785224] mmc1: host does not support reading read-only switch, assuming write-enable [ 418.931992] mmc1: new ultra high speed SDR104 SDHC card at address 0007 [ 418.940000] mmcblk1: mmc1:0007 SD32G 29.0 GiB [ 418.947404] mmcblk1: p1 [ 419.146762] FAT-fs (mmcblk1p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
可通过df命令查看SD卡挂载位置:

可通过如下命令查看、读写当前SD卡的内容:
# ls /run/media/mmcblk2p1/ #查看SD卡的内容 # cd /run/media/mmcblk2p1/ #进入SD卡目录 # touch test #创建test文件 # rm test #删除test文件
USB HOST 测试
以U盘为例,将U盘插入USB HOST接口【J20、J21、J22、J23】其中任意一个,系统会默认将U盘挂载在/run/media目录下,并打印如下消息:

可通过df命令查看U盘挂载位置:

通过如下命令查看、读写U盘内容:
# ls /run/media/sda1/ #查看U盘的内容 # cd /run/media/sda1/ #进入U盘目录 # touch test #创建test文件 # rm test #删除test文件
以太网测试
使用网线将开发板的网口【P3】与PC机的网口连接,设置PC机的IP地址为192.168.1.115,子网掩码为:255.255.255.0
配置开发板的网络,如下:
# ifconfig eth0 192.168.1.200 netmask 255.255.255.0 #配置开发板IP地址与PC机在同一网段 # ping 192.168.1.115 #通过ping命令进行本地网络测试
如需连接外网,需根据路由器网关进行配置,如下:
# route add default gw 192.168.1.1 #设置默认路由网关 # ping www.baidu.com #通过ping命令进行互联网测试
串口测试
录音/播放测试
测试前将耳机与MIC分别插入对应的连接器。
录音测试
# arecord -Dhw:0,0 -d 10 -f cd -r 44100 -c 2 -t wav test.wav
播放测试
# aplay test.wav
注意:aplay不能播放MP3
多媒体播放测试
使用gplay-1.0播放器进行测试,gplay-1.0使用说明:
- h 显示操作帮助
- p 播放命令
- s 停止命令
- a 暂停/继续命令
- v 音量设置
- m 静音或去除静音
- >下一个视频文件
- <上一个视频文件
- r 重复播放或单次播放
- t 旋转视频播放
- i 多媒体文件信息。
测试方法
# gplay-1.0 /unit_tests/test.mp4 #MP4播放 # gplay-1.0 /unit_tests/test.mp3 #MP3播放
时钟测试
通过向RTC写/读时间,以及断电,重启后查看系统时间同步情况来验证RTC功能
开发板【J16】安装装纽扣电池
- 查看系统时间:
# date Mon Aug 12 05:18:57 UTC 2019 #当前系统时间
- 查看硬件时间:
# hwclock Mon Aug 3 06:28:06 2019 0.000000 seconds #当前硬件时间
- 设置系统时间:
# date -s "2019-10-10 09:51:50" Thu Oct 10 09:51:50 UTC 2019 #设置系统时间
- 将系统时间写入硬件时间:
# hwclock -w #同步硬件时间
断电重启后,查看系统时间和硬件时间,时间同步说明设置成功。

BT测试
开发板提供⼀个WiFi/BT模块Fn-link6222b,wifi型号为QCA6714,蓝牙是串口模块,与 ttymxc2相连,本章用开发板蓝牙连接PC端蓝牙来测试蓝牙功能
测试前连接天线到U5,以免信号弱导致无法连接
- 绑定串口
- 使用hciattch命令 来绑定ttymxc2串口,命令如下
rtk_hciattach -n -s 115200 ttymxc2 rtk_h5 &
- 打开wlan
- 可以用rfkill unblock 0 或者rfkill unblock bluetooth。 测试时,请先关闭 bluetooth,再打开
# rfkill list 0: hci0: bluetooth Soft blocked: yes Hard blocked: no # rfkill unblock bluetooth # rfkill list 0: hci0: bluetooth Soft blocked: no Hard blocked: no
- 连接蓝牙
- 使用bluetoothctl工具来控制蓝牙进行扫描和连接。

NFS测试
服务器配置
- 安装服务端软件
$ sudo apt-get install nfs-kernel-server
- 编辑配置文件,
$ sudo vim /etc/exports
- 在最后加入如下内容:
/home/work/share 192.168.1.*(rw,sync,no_root_squash) //允许192.168.1.*网段内的主板访问本机/home/work/share目录
- 重启NFS服务
$ sudo service nfs-kernel-server restart
客户端配置
- 查看服务器共享目录
# showmount -e 192.168.1.8 Export list for 192.168.1.8: /home/work/share 192.168.1.*
- 设置开发板ip地址,同服务器在同一网段
- 挂载服务器目录到/mnt,为了提高nfs的稳定性,使用TCP协议挂载,nfs默认用UDP协议
# mount -t nfs 192.168.1.8:/home/work/share /mnt -o proto=tcp -o nolock
- 卸载NFS
# umount /mnt
