OPENOCD INSTALL

[注]：请直接转到第二次安装详解。

[gif教程]：翻到最后 20150419

第一次使用openocd。问题连篇! （JZ2440开发板，命令用蓝色粉刷）

一:安装openocd:


cd /path/you/install/openocd

(1) 通过 git 获取openocd


git clone git://openocd.git.sourceforge.net/gitroot/openocd/openocd

遇到问题：

Cloning into 'openocd'...
fatal: unable to connect to openocd.git.sourceforge.net:
openocd.git.sourceforge.net: No address associated with hostname

(2)源码编译安装


sudo apt-get install autoconf

./bootstrap

...

error: required directory ./jimtcl does not exist(安装失败，并且丢失了jimtcl)

./configure

configure: error: jimtcl not found, run git submodule init and git submodule update.（丢失了jimtcl）

sudo git submodule init

sudo git submodule update

Cloning into 'jimtcl'...
remote: Counting objects: 6287, done.
remote: Compressing objects: 100% (1595/1595), done.
Receiving objects:   2% (126/6287), 28.00 KiB | 3.00 KiB/s

下载完成后：

sudo ./bootstrap

xnus@xnus-P43E:/opt/openocd$ sudo ./bootstrap
[sudo] password for xnus:
+ aclocal
+ libtoolize --automake --copy
+ autoconf
+ autoheader
+ automake --gnu --add-missing --copy
Makefile.am:23: warning: wildcard $(srcdir: non-POSIX variable name
Makefile.am:23: (probably a GNU make extension)
Setting up submodules
Bootstrap complete. Quick build instructions:
./configure ....

(3) 驱动安装


sudo apt-get install libftdi-dev libftdi1 libtool git-core asciidoc

./configure --help

./configure 　--enable-maintainer-mode　--enable-usb_blaster_libftdi 　--enable-openjtag_ftdi

(不行的话多试几次！)

make

make install

输出版本信息

openocd -v

二：配置openocd.cfg

 参考百问网的配置修改

三：启动OpenOCD
 

将开发板连接的OpenJTAG的USB端口接入PC，终端输入openocd
 

xnus@xnus-P43E:~$openocd
 

Open On-Chip Debugger 0.8.0 (2015-01-30-21:54)Licensed under GNU GPL v2For bug reports, read    http://openocd.sourceforge.net/doc/doxygen/bugs.htmlInfo : only one transport option; autoselect 'jtag'adapter speed: 1234 kHzfast memory access is enabledtrst_and_srst separate srst_gates_jtag trst_push_pull srst_open_drain connect_deassert_srstWarn : Using DEPRECATED interface driver 'ft2232'Info : Consider using the 'ftdi' interface driver, with configuration files in interface/ftdi/...Info : clock speed 1200 kHzInfo : JTAG tap: s3c2440.cpu tap/device found: 0x0032409d (mfg: 0x04e, part: 0x0324, ver: 0x0)Info : Embedded ICE version 2Info : s3c2440.cpu: hardware has 2 breakpoint/watchpoint units
 

四：启动telnet



 

xnus@xnus-P43E:~$ telnet localhost 4444
 

Trying 127.0.0.1...Connected to localhost.Escape character is '^]'.Open On-Chip Debugger

可以看到灯开始闪烁了（注意，应设置为NAND启动）
 

 

========================分割线================================================华丽的=================================================
 

第二次使用openocd。问题亦是连篇!！ （mini2440开发板，命令用绿色粉刷）
 

我在/home/xnus下新建了一个目录：InStall
 

cd InStall
 

git clone git://openocd.git.sourceforge.net/gitroot/openocd/openocd （注意：这个命令我至少尝试了5次！！不是链接超时就是检测不到目标地址！）



Cloning into 'openocd'...fatal: unable to connect to openocd.git.sourceforge.net:openocd.git.sourceforge.net[0: 218.85.65.150]: errno=Connection timed out
 

终于有一次链接上：

下载速度及其的慢。苦逼等待中........下载完成

我的理解是没有检测到CPU，对openocd.cfg做部分修改：
 

 

set _TARGETNAME $_CHIPNAME.cpu
target create $_TARGETNAME arm920t -chain-position $_TARGETNAME
$_TARGETNAME configure -work-area-phys 0x00200000 \
-work-area-size 0x4000 -work-area-backup 0
保存，重新运行openocd-> 

 

sudo openocd

总算成功了！在Ubutu14.04下，如何用OpenJTAG+OPENOCD烧写程序
 

总结了一下，关键的几个地方就是，configure的时候要把该config的都选上，如我们的（./configure --enable-maintainer-mode --enable-legacy-ft2232_libftdi）。还有就是
 

openocd.cfg文件的配置。以下贴出mini2440的配置文件->

我是参考上面的配置文件还有openocd.pdf写的。
 


 

续：
 

可以将openocd.cfg复制到/usr/local/openocd/script/ 目录下，这样就能在用户根目录或者其他目录下执行sudo openocd了。
 

下面我们将u-boot下载到？里面。（以下是Nor启动，将init,bin下载到0x40000000。如果是nand启动，则下载到0x0）
 

sudo openocd启动openocd
 

telent localhost 4444
 

halt
 

load_image /home/xnus/Bare/init.bin 0x40000000
 

resume 0x40000000
 

可以看到灯在闪，初始化存储控制器成功。
 

接下来我们先将minicom启动起来，设置好之后接着执行下面步骤
 

halt
 

load_image /home/xnus/Bare/u-boot 0x33f80000
 

resume 0x33f80000
 

可以在minicom中看到u-boot的消息了。
