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
* G/ _8 Q# y4 J! @* R/ E1 {7 i- ~6 W7 d. M" r5 J* Z
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

! W: D' j x# `+ J5 d! M, j. V7 N( t/ A2 G( U
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3 K4 [0 e- P2 {" ~+ P/ ^

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）：( \( _ s( o8 G
