Installing OpenOCD From Source
If you want to load your source code into the microcontroller from your Linux development host then look no further... open OCD is the tool for you. The instruction in here are only applicable to linux OS.
Ok, so lets start... You can download the openocd from openOCD main page or by executing below command:
wget http://sourceforge.net/projects/openocd/files/openocd/0.9.0-rc1/openocd-0.9.0-rc1.tar.bz2
Then simply unpack the downloaded file with:
tar xjfv openocd-0.9.0-rc1.tar.bz2\r\ncd openocd-0.9.0-rc1
In there you can/should read the README file as it describes some additional options, like binary prefix/suffix or location, you can use while compiling the source. I dont need any of the extra stuff so i simply do:
./configure
Read the output as it will tell you what packages you might be missing that are required for installation. At the end of the output you will most likely see something like that:
OpenOCD configuration summary
--------------------------------------------------
MPSSE mode of FTDI based devices no
ST-Link JTAG Programmer no
TI ICDI JTAG Programmer no
Keil ULINK JTAG Programmer no
Altera USB-Blaster II Compatible no
Versaloon-Link JTAG Programmer no
Segger J-Link JTAG Programmer no
OSBDM (JTAG only) Programmer no
eStick/opendous JTAG Programmer no
Andes JTAG Programmer no
USBProg JTAG Programmer no
Raisonance RLink JTAG Programmer no
Olimex ARM-JTAG-EW Programmer no
CMSIS-DAP Compliant Debugger no
It most likely just means you are missing the libusb libraries on your system. On fedora you can easily install it with:
sudo yum install libusb-devel libusbg libusb
After installation just run ./configure again and you should see:
OpenOCD configuration summary

ST-Link JTAG Programmer yes (auto)

USBProg JTAG Programmer yes (auto)
Raisonance RLink JTAG Programmer yes (auto)
Olimex ARM-JTAG-EW Programmer yes (auto)
CMSIS-DAP Compliant Debugger no
Then you can just type:
make
sudo make install
The last command will install the binaries in the specified path, by default it's /usr/local/bin.
Now, notice a tcl/ directory in the openocd folder. You can copy it to somewhere easily accessible as you will be accessing it often. It contains the configuration files for different target (microcontrolers or dev boards) and interface configs ( olimex, st-link, u-link). So assuming that you are in the tcl/ directory and that your stm32Discovery board is connected to laptop you should be able to run:
sudo openocd -f board/stm32f4discovery.cfg -f interface/stlink-v2.cfg
And you should see:
[kris@facehugger tcl]$ sudo openocd -f board/stm32f4discovery.cfg -f interface/stlink-v2.cfg

Dont worry about the warnings. We will fix them someday when we learn more about the software. Then from different console window type in:
telnet localhost 4444
And you should see:
[kris@facehugger stm32_dev]$ telnet localhost 4444

Connected to localhost.

There are tons of commands to execute so I advice to check with the openOCD manual that can be downloaded here. But just as a quick test run:
> reset halt
> reset run
Will stop/start the loaded program execution.
