== Download the GNU/ARM toolchain ==
* tar -xvjf gcc-arm-none-eabi-4_8-2014q2-20131204-linux.tar.bz2
* export PATH=$PATH:~/gcc-arm-none-eabi-4_8-2014q2/bin
== Download and Build STLINK ==
* sudo apt-get install autoconf pkg-config libusb-1.0 git
* git clone https://github.com/texane/stlink.git
<pre>
cd ~/stlink
./autogen.sh
./configure
make
</pre>
== Download STM32 Libraries and Blinky Example ==
* git clone https://github.com/rowol/stm32_discovery_arm_gcc
== Compile Your Source Code ==
* Edit Makefile
** STLINK=/home/rowol/stlink             #Example, change to your location
** STM_COMMON=/home/rowol/stm32_discovery_arm_gcc/STM32F4-DISCOVERY_FW_V1.1.0
** make it
== Program ARM's Flash and Run Code ==
* make burn
or
* st-flash write STM32F4-Discovery.bin 0x08000000

== Using external ST-Link ==
* Remove CN3 jumper
<pre>
ST-Link     STM32F4
VCC            3V
SWIO           PA13
SWCLK          PA14
VDD            VDD ( depends on product, could range from 1.8v - 5v )
GND            GND
</pre>

== GDB ==
<pre>
In the directory with your source code, I've also add a .gdbinit file which contains:

define reload
kill
monitor jtag_reset
load
end

target extended localhost:4242
load

This will execute whenever you start GDB in the source directory

To start up:

~/stlink/st-util                 #Start GDB server
arm-none-eabi-gdb main.elf       #In a second terminal window, start GDB

continue                         #Starts code running, or use other GDB commands to 
                                 # set breakpoints, etc first...
