OpenOCD - Using JLink For ubuntu and Windows 7(Cygwin)

OpenOCD is an open-source project aiming providing a online debugger, originating from a thesis.

for more information, please go to http://openocd.sourceforge.net/

you can compile yourself, thus you can know more and modify according to situation.

Or you can download the complied one: windows version by Freddie Choplin

Step 0: some preparations for windows

Install cygwin and additional tools from the development package:

- autoconf: Wrapper scripts for autoconf commands

- automake: Wrapper scripts for automake and aclocals

- gcc: C compiler upgrade helper

- libusb-win32: libusb-win32: USB programming library

- make: The GNU version og the 'make' utility

- subversion: A version control system

Step1: install Jlink drivers
for Linux(ubuntu)

$./configure

if there is an error like "cannot find usb.h"

you need to install libusb:

please refer to

http://hi.baidu.com/cndx100/blog/item/2b933f19b6a8b265dbb4bdf7.html

for windows
(forcygwin, you need to use cygwin to install libusb)

because openocd talks to jlink via libusb, not the jlink.dll provided from segger.com

so you need to download the libusb-win32 driver to replace segger driver
http://cdnetworks-kr-2.dl.sourceforge.net/project/libusb-win32/libusb-win32-releases/1.2.6.0/libusb-win32-bin-1.2.6.0.zip
and run the inf-wizard.exe in its bin folder



and then installation comes to you, just go ahead. or you can update your driver yourself.

you can check in the device manager,



Step2 openocd installation

firstly, down OpenOCD files

http://sourceforge.net/projects/openocd/files/openocd/

$./configure --enable-jlink //configure to situation, generate makefiles; for more configure options,you need to refer to the official documents.

$./make

.$/make install

then you can test

$openocd -v

For Windows(Cygwin)

a exe file in the src folder is generated after make

type in cygwin

$openocd -f interface/jlink.cfg -f target/stm32f1x.cfg

or cmd

c:\>openocd -f interface/jlink.cfg -f target/stm32f1x.cfg

// openocd has been added to path in environmental variables and you

//you need to copy cygwin.dll and cygusb0.dll to src folder.
