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: ^5 H6 N/ W* \4 V$ i4 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.bin4 B4 T' ~5 S' h6 X( H

2. 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 L- v7 ?# H3 c+ d

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
