前几天上电试试，结果系统起不来，哎！
只好刷系统咯，先刷了一个Ubuntu吧，我对这个比较熟，是Linux最好的桌面系统之一。
1.下载并安装系统烧写工具 IH固件烧写工具。下载链接：http://mirror.lemaker.org/IH_FW_Burning_Tool_For_Windowns_V2.01.03.zip
2.如果你想从EMMC NAND Flash启动操作系统，你必须在EMMC NAND Flash上安装一个操作系统。LeMaker Guitar可以利用核心板上的硬“ADFU”按键或底板上的软“ADFU”按键进入ADFU模式去烧系统固件。建议使用软“ADFU”按键进入ADFU模式。下面的步骤将告诉你如何将一个操作系统固件烧写到EMMC NAND Flash上。
在这里一定要注意了，要按住核心板上的升级ADFU按键哦，底板上的不起作用咧！
3.打开固件文件，点击“下载”，烧写系统固件到EMMC，耐心等待，直到固件烧写完成，重启即可！
4.测试：
上电后，uboot已经启动，能引导内核，结果呢，还是挂掉了！

心酸啊，再去看看uboot:

emmc烧录我这里也没有成功，今天搞了一个u***3.0的线来试试。

如果不能从EMMC启动，那你能够从SD卡启动吗？你可以把SD卡，或EMMC先格式化干净，再重新烧写系统。
