1.、Download Toolchain
Visit GNU Tools for ARM Embedded Processors or just use one of the links below to download it
2、Install automake
Mac OS:
$ brew install automake
Linux:
$ sudo apt get install automake
3、Make a New Directory and decompress the tar.bz2 file you download
Mac OS:
$ cd {Your workspace}
$ mkdir toolchain
$ mv {Your download} toolchain
$ cd toolchain
$ tar -jxvf gcc-arm-none-eabi-4_9-2015q2-20150609-mac.tar.bz2
Linux:
$ cd {Your workspace}
$ mkdir toolchain
$ mv {Your download} toolchain
$ cd toolchain
$ tar -jxvf gcc-arm-none-eabi-4_9-2015q2-20150609-linux.tar.bz2
4、Set environment variable
*If you close the terminal , the environment variable set by export command will disappear .
You need to do those things again when you open a new terminal .
( If you want to permanently export a variable --> google it )

$ cd {Your workspace}
$ cd toolchain/gcc-arm-none-eabi-4_9-2015q2/bin
$ export PATH=$PATH:`pwd`
5、Get st-util tool (stlink tool)
$ cd {Your workspace}
$ mkdir sttool
$ cd sttool
$ git init
$ git pull https://github.com/texane/stlink
$ ./autogen.sh
$ ./configure
$ make
$ sudo make install
6、Download stm32f4 blink example
$ cd {Your workspace}
$ mkdir blink
$ cd blink
$ git init $ git pull https://github.com/SAM33/STM32F4Blink.git
7、Connect your stm32f4 to computer , and open a new terminal to run st-util
Mac OS:
$ st-util
Linux:
$ sudo st-util
You will get some message like this :
Remember the port which gdbserver running .
8、Go back to last terminal and make stm32f4 blink example
$ cd {Your workspace}
$ cd blink
$ make
9、Upload elf file to stm32f4
$ cd {Your workspace}
$ cd blink
$ arm-none-eabi-gdb
(gdb) tar ext localhost:4242
(gdb) load build/blink.elf
Loading section ..............
Loading section ..............
Loading section ..............
(gdb) run
The program being debugged has been started already.
Start it from beginning? (y or n) y
//now you will see stm32f4 board blinking !!
//stop : input ctrl^c twice
ctrl^c ctrl^c
//close gdb
(gdb) ctrl^d
A debugging session is active ....
Quit anyway? (y or n) y
This command : (gdb) tar ext localhost:???? ----> ???? is the port you remember
Enable gdb remote debuging using st-util gdb server . You will get some log in your st-util windows ,
