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

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

! d$ N% q; F- v9 \1 \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

& g, L+ N' r' [
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

uboot配置参数如下（由于没有开发板没有自动获取mac地址，所以自己设置为：  setenv  ethaddr 00:0c:29:bc:7e:9a）：
