TL138/6748/1808F-EasyEVM-A2使用ti-processor-sdk-linux-omapl138-lcdk-04.00....

uestczwj

0.  开发板型号：  TL138/6748/1808F-EasyEVM-A2, 开发版启动模式模式为SD卡启动

1.  在ubantu16.04（64bit）按照官网安装ti-processor-sdk-linux-omapl138-lcdk-04.00.00.04-Linux-x86-Install.bin

3 r% w2 z7 ?! E, v0 C2.  把uboot， kernel， filesystem写入SD卡, 拨码开关设置为SD启动， 能够正常启动能够进入嵌入式开发版

3.  SD卡启动方式保持不变，但是在uboot中配置为tftp下载内核和nfs挂载方式

0 _9 _; e8 Y2 F7 {: k4 P您好，我们光盘资料里面，有提供相关的nfs组件安装包和搭建的指导文档，建议您先按照我们的资料去搭建，我们使用的是，基于Ubuntu12.04的nfs开发环境搭建。
