SAMA5D4 Xplained Ultra第一次启动

ddllxxrr

这个板子高大上，只有一个小卡片的说明。总结一下所有的资料跑不过两个网址：
www.atmel.com/sama5d4xplained
www.Linux4SAM.com
一个是关于硬件一个是关于软件。
然后是到www.atmel.com网站下载一个Atmel USB驱动：
在网站的首页的atmel gallery中。

然后安装，由于本人的笔记本里以有了Atmle　EDBG驱动，所以就直接把开发板插到ＵＳＢ口，另一个连到板子的EDBG-USB。
这时查出ＣＯＭ号为ＣＯＭ２５。
由是打开串口助手之类听串口工具，然后复位下开发板，打印信息如下。

这时可登录了，键入root没有密码。
