OPENOCD终于运行起来了…

Posted by admin in 技术研发 on 一月 27th, 2009

先是按这里进行..

成是成了,不过那个FT2232添加不成功,好README好像和上面说的有变化了
还好我不用这个,所以就没有编译进去
结果运行不成功
原来现在的新版本的初始化化脚本变了..
OLD SYNTAX: DEPRECATED – translating to new syntax
jtag newtap CHIP TAP -irlen 8 -ircapture 0×01 -irvalue 0×0e3
Example: STM32 has 2 taps, the cortexM3(len4) + boundryscan(len5)
jtag newtap stm32 cortexm3? ….., thus creating the tap: “stm32.cortexm3″
jtag newtap stm32 boundry? ….., and the tap: “stm32.boundery”
And then refer to the taps by the dotted name.

不过发现自带了一个CFG文件文件(在target目录下)
于是使用:
注意:使用前要先修改parport.cfg的parport_port 0xc8b8 =>parport_port 0×378
0×378为LTP1的地址!
openocd -f interface/parport.cfg -f target/lpc2148.cfg
结果显示:
Error: missing privileges for direct i/o

网上搜索发现原来是使用这个来驱动并口的..
http://www.cs.ucr.edu/~eblock/pages/pictools/giveio.html
于是下载并启动这个服务,,果然,OK

后来又逛OPENOCD的maillist发现了这个:
https://lists.berlios.de/pipermail/openocd-development…………html
这下好了,也许下次别人使用的时候再也不用安装那个CYGWIN了
而且版本也比较新,那我就也用这个吧,这样以后好和别人交流
而且发现这个版本里面竟然已经在drivers目录下面放了giveio的驱动了..,
解压再运行install_giveio.bat即可

OK it’t working…..

按说明COPY了一份WGET的脚本

Posted by admin in 技术研发 on 一月 23rd, 2009

#!/bin/sh # wget-list: manage the list of downloaded # file wget_sh # invoke wget-list without arguments # edit file listfile. while [ `find wget-list -size +0` ] do url=`head -n1 wget-list` wget -c $url sed -si 1d wget-list done #end wget_sh
这样子就可以自动下载wget-list列表中的文件并删除已经下载过的了
没完成可以接着下
使用：sh ./wget_sh
注意：find 后面接列表文件
