多媒體視頻高清處理芯片——Freescale i.MX6 開發(fā)板(IAC-IMX6-Kit)評(píng)測(cè)

  • i.MX 6Dual(簡(jiǎn)稱i.MX6D)是一款來自NXP(前稱Freescale)的高端3D圖形處理芯片,采用雙核ARM Cortex-A9架構(gòu)。今天給大家介紹的就是基于i.MX6D為主控設(shè)計(jì)的第三方開發(fā)板——Freescale i.MX6 開發(fā)板,來自于NXP的合作伙伴Qiyang科技。
修復(fù)安裝(4)

4) 應(yīng)用程序測(cè)試。

復(fù)制驅(qū)動(dòng)的程序,buzzer_test(驅(qū)動(dòng)源程序),include(頭文件)并編譯。輸入內(nèi)容及執(zhí)行情況如下:

5) 連通網(wǎng)絡(luò):

查看開發(fā)板的ip地址。

通訊測(cè)試:

可以用ifconfig eth0 192.168.154.71來臨時(shí)修改開發(fā)板的IP地址,也可以在開發(fā)板上電時(shí),通過setenv方式來修改IP地址等信息。兩者的區(qū)別在于再次給開發(fā)板上電時(shí),前者的ip參數(shù)不會(huì)被保留,后者會(huì)保存下來,F(xiàn)在以后者為例來進(jìn)行修改,注意與主機(jī)的ubuntu地址在同一網(wǎng)段內(nèi)。方法如下視圖。
