  • i.MX 6Dual(简称i.MX6D)是一款来自NXP(前称Freescale)的高端3D图形处理芯片,采用双核ARM Cortex-A9架构。今天给大家介绍的就是基于i.MX6D为主控设计的第三方开发板——Freescale i.MX6 开发板,来自于NXP的合作伙伴Qiyang科技。
修复安装(4)

4) 应用程序测试。

复制驱动的程序,buzzer_test(驱动源程序),include(头文件)并编译。输入内容及执行情况如下:

5) 连通网络:

查看开发板的ip地址。

root@fire /$ ifconfig

can0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

通讯测试:

root@fire /$ ping 192.168.154.30

PING 192.168.154.30 (192.168.154.30): 56 data bytes

64 bytes from 192.168.154.30: seq=0 ttl=64 time=4.658 ms

64 bytes from 192.168.154.30: seq=1 ttl=64 time=0.584 ms

64 bytes from 192.168.154.30: seq=2 ttl=64 time=0.520 ms

64 bytes from 192.168.154.30: seq=5 ttl=64 time=0.514 ms

可以用ifconfig eth0 192.168.154.71来临时修改开发板的IP地址,也可以在开发板上电时,通过setenv方式来修改IP地址等信息。两者的区别在于再次给开发板上电时,前者的ip参数不会被保留,后者会保存下来。现在以后者为例来进行修改,注意与主机的ubuntu地址在同一网段内。方法如下视图。
