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( P: H+ N: t( q+ L8 v; E' K
- J8 [% S5 [; }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, ~" w, {7 I! q. f) j( S$ H0 ~+ X

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）：

4. 能够通过tftp下载并启动内核，但是在挂载NFS文件系统之前报错（错误在下面内核启动信息的最后）：
