Before we used the summon-arm-toolchain script to make the crosscompiler tool, but now summon-arm-toolchain is not maintained anymore and now they recommend to use the official toolchain from ARM:

https://launchpad.net/gcc-arm-embedded

Also you must install the following packages:

sudo apt-get install libftdi1 openocd libusb-1.0-0-dev

To install:

1. Set multiarch in your system.

• To add an extra architecture (in Debian from dpkg 1.16.2 onwards) the syntaxis is as follows:

    dpkg --add-architecture <arch>

• For a complete list of official architectures go to: http://www.debian.org/ports/
• We need to add i386 arch using the follwing command:

    dpkg --add-architecture i386

• Your dpkg architectures are stored in /var/lib/dpkg/arch.
• Now, modify /etc/apt/sources.list. Apt-sources can be architecture qualified with this syntax for each 'source':

    deb [arch=amd64,i386] http://site.example.com/debian distribution

• Next, do apt-get update always after adding new architectures.

1. Get the dependencies:

sudo apt-get install libncurses5:i386

1. Download the latest installation tarball for GNU Tools for ARM Embedded Processors, and uncompress:

cd ~/local/src
wget https://launchpad.net/gcc-arm-embedded/4.9/4.9-2014-q4-major/+download/gcc-arm-none-eabi-4_9-2014q4-20141203-linux.tar.bz2
tar -xjf gcc-arm-none-eabi-4_9-2014q4-20141203-linux.tar.bz2

1. Make the toolchain executables available to the users add the bin directory to your PATH variable:

echo 'export PATH=$PATH:/home/****user****/local/src/gcc-arm-none-eabi-4_9-2014q4/bin/' >> /home/****user****/.bashrc

1. Remember to reload your .bashrc file, there are two ways:

• Close your session and login again.
• Reloading your .bashrc file directly:

. .bashrc

First we need to install the package: libusb-1.0

También se debe seguir el tutorial Using xstow for local installations antes de continuar con la instalación.

Primero ingresamos a la carpeta

cd ~/local/src/

Se descarga con git

git clone https://github.com/texane/stlink

Ingresamos a la carpeta

cd stlink

Configuramos

mkdir build
cd build
ccmake ..

Presione “c”. Seleccione en CMAKE_BUILD_TYPE=debug. Luego en CMAKE_INSTALL_PREFIX=/home/user/local/DIR/stlink Presione “c”, y luego “g” denuevo.

Compilamos, e instalamos

make
make install 
cd 
cd local/DIR
xstow stlink

Ahora necesitamos copiar las siguientes reglas (tenemos que estar ubicados en ~/local/src/stlink/etc/udev/rules.d/),

sudo cp 49-stlinkv1.rules /etc/udev/rules.d/
sudo cp 49-stlinkv2.rules /etc/udev/rules.d/
sudo cp 49-stlinkv2-1.rules /etc/udev/rules.d/
sudo /etc/init.d/udev restart
udevadm control --reload-rules
udevadm trigger --attr-match=subsystem=usb

http://www.libopencm3.org/

To build the library:

cd ~/local/src/
git clone https://github.com/libopencm3/libopencm3-examples
cd libopencm3-examples
git submodule init
git submodule update
cd libopencm3
make

Be sure to install python-yaml first.

To build an example and flash it to the f4discovery:

cd ../
cd examples/stm32/f4/stm32f4-discovery/miniblink/
make
make flash

New versions use STLINK 2-1. If you have errors, flashing the microcontroller, you should change your OOCD_INTERFACE configuration in the corresponding Makefile or passing as an argument on the flash instruction as seen below:

$ make flash OOCD_INTERFACE=stlink-v2-1
