omapl138EVM 启动过程详细描述

前一年，探索了一阵OMAPL137，现在决定转到OMAPL138上来，其原因颇多不多述。

安装最新的DVSDK，其版本号为，ti-dvsdk-omapl13-evm-04-03-00-06

按照其setup.sh脚步运行，效果不张，不就那点事吗？决定从头来过：

1.配置tftp

2.配置nfs

3.安装minicom---某家留存文档放到此处

-------------------------------------------------------------------------------

用tftpd-hpa 及tftp-hpa
0)3G天意的应用，网络可得；
1)用新立得清空所有原来的tftp,tftpd,或tftpd-hpa,tftp-hpa等；
2)建立/tftpboot目录，设置为可读可写，用户属性设置为nobody
3）sudo emacs /etc/default/tftpd-hpa如下：
# /etc/default/tftpd-hpa
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/tftpboot"
TFTP_ADDRESS="0.0.0.0:69"
TFTP_OPTIONS="-l-s-c"
4）注意网络之无线网络的设置不用，设置好IPV4 ，172.28....;
5)重启
6）test 方法：
   a)设置两台计算机，其tftpd-hpa及tftp-hpa如同以上步骤；
   b)按上述步骤操作完成后，设置
test:

cd /tftpboot

host@ echo  "i love s.. & linux">> testfile.txt

--@home/../tftp 172....

put 

get

test ok!

1)安装NFS服务器程序
使用Synaptic(新立得)软件包管理器安装，搜索“nfs”,选择软件包"nfs-kernel-server"项进行安装
可以使用netstat命令检查nfs端口是否已经打开：
netstat-tl

2)启动和停止nfs服务

   虽然完成nfs安装后会自动启动nfs，但要调整共享资源还得重新启动nfs服务，以使配置生效。

   命令方式手动启动和停止nfs服务

     启动nfs服务：
     sudo /etc/init.d/nfs-kernel-server start
     停止nfs 服务
     sudo /etc/init.d/nfs-kernel-server stop
     重启nfs服务
     sudo /etc/init.d/nfs-kernel-server restart
     查看nfs服务当前状态
     sudo /etc/init.d/nfs-kernel-server status

 3)  nfs服务器配置
建立共享文件夹/nfs,改属性、所有 777,nobody.
    sudo emacs /etc/exports
 #
 /nfs *(rw,no_root_squash,sync)
4)重启，注意网络连接，去掉3G
5）掛载共享资源 -from pc to notebook
   sudo mount 172.....3:/nfs /tftpboot

-------------------------------------------------------------------------------

1)新立德 minicom
2)sudo minicom -s
3)setup 选择， 串口驱动为 : /dev/ttyUSB0 或 ／dev/ttyUSB3(看一下）

----------------------------------------------------------------------------

4.取得uImage 内核文件将其放到/tftpboot里

从DVSDK包里取得，在/tftpboot 目录里有文件uImage-da850-omapl138-evm.bin（按脚步装后有的文件，在ti-dvsdk-omap.../psp/prebuilt-images

中有，注意，应将其更名为uImage ,mv ...bin uImage

5.取得nfs文件系统，并将其移动到/nfs

解压，tar -zxvf  dvsdk-da850-omapl138-evm-rootfs.tar.gz

6.启动 omapl138evm 板
