Base Environment

Install Compiler gcc-arm-none-eabi

Download last version of GCC ARM Embedded from: https://launchpad.net/gcc-arm-embedded/+download

Untar the compiler:

tar -xvjf gcc-arm-none-eabi-<VERSION>.tar.bz2

Copy it to a common place:

sudo cp -r gcc-arm-none-eabi-<VERSION> /opt/compilerSTM32

Important!! If in a 64 bits machine, you will need to install the following libs:

sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 

Install OpenOCD On-Chip Debugger

Install dependencies:

sudo apt-get install flex bison libgmp3-dev libmpfr-dev libncurses5-dev libmpc-dev autoconf texinfo build-essential \
libftdi-dev libusb-1.0-0-dev libexpat1-dev

Download last version of Openocd from: http://openocd.org/

Untar openocd:

tar -xvzf openocd-<VERSION>.tar.gz

Go into the directory:

cd openocd-<VERSION>

Configure openocd compilation:

./configure --prefix=/opt/openocd/ --enable-jlink --enable-amtjtagaccel --enable-ftdi --enable-buspirate --enable-stlink \
--enable-ftdi --enable-rlink

Compile it:

make

Install:

sudo make install

Prepare its use according to udev:

(old versions)
sudo cp -r contrib/openocd.udev /etc/udev/rules.d/90-jtag.rules

(new versions)
sudo cp -r contrib/99-openocd.rules /etc/udev/rules.d/

sudo udevadm control --reload-rules

Grant permits to user: user must be in plugdev:

sudo vi /etc/group

Basic Usage

Need to load environment. Create a env.sh file with:

export PATH=/opt/openocd/bin:/opt/compilerSTM32/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

Load the environment:

source env.sh

Open ocd:

openocd -f openocd.cfg -c "init" -c "halt" -c "reset halt"

Eclipse Environment

It is mandatory to install the Base Environment first

Install Eclipse

(More info at: http://help.eclipse.org/mars/index.jsp?topic=%2Forg.eclipse.cdt.doc.user%2Fgetting_started%2Fcdt_w_import.htm)

Download last version of Eclipse IDE for C/C++ Developers from: http://www.eclipse.org/downloads/

Untar eclipse:

tar -xvzf eclipse-cpp-<VERSION>-linux-gtk-x86_64.tar.gz

Go into directory and execute eclipse:

cd eclipse
./eclipse

Define workspace (e.g. /home/<USER>/stm32EclipseWorkspace)

Install C/C++ Developping tools

Go to Help -> Install New Sofware -> Choose from the drop-down list
- Name: CDT-<ECLIPSE VERSION>
- Location: http://download.eclipse.org/tools/cdt/releases/<VERSION>
For example:
- Name: CDT-Neon.2
- Location: http://download.eclipse.org/tools/cdt/releases/9.2

- Click Ok
- Select: CDT Optional Features -> C/C++ GDB Hardware Debugging
- Next, Next, Agree, Finish
- Restart

Install GNU ARM Plugins

Go to Help -> Install New Sofware -> add
- Name: GNU ARM Eclipse Plugins
- Location: http://gnuarmeclipse.sourceforge.net/updates

- Click Ok
- Select All
- Next, Next, Agree, Finish
- You will be asked to accept some specific not known content, do it
- Restart

Import Project

(More info at: http://gnuarmeclipse.github.io/plugins/install/)

Go to File -> New -> C Project
- Name: test
- Location: Select where the code is
- Project type -> Makefile project -> Empty Project -> Cross ARM GCC

- Next, Next

Toolchain:
- Name: GNU Tools for ARM Embedded Processors (arm-none-eabi-gcc)
- Path: /opt/compilerSTM32 (if installed as in previous section, if not check where did you do it!!)

- Finish

If everything ok, you are able to compile with the hammer.

Set OpenOCD

(More info at: https://balau82.wordpress.com/2014/02/23/stm32-p152-development-with-eclipse-on-linux/)

- Run -> External tools -> External Tools Configurations
- Program -> New
- Location: /opt/openocd/bin/openocd (if installed as in previous section, if not check where did you do it!!)
- Working Directory: A Dir where there is the openocd.cfg (typically where our porject is)
- Arguments: -f openocd.cfg -c "init" -c "halt" -c "reset halt" - Apply

Set GDB

(More info at: https://pixhawk.org/dev/jtag/gdb_eclipse)

Go to Run -> Debug Configurations
Create a GDB Hardware Debugging
In Main:
- Application: The .elf file that will be generated by the project (e.g. sensedin.elf)
- Project: The project location
- Use workspace settings
- Select legacy GDB Hardware Debugging Launcher by clinking Select other

In Debugger:
- GDB Command: /opt/compilerSTM32/bin/arm-none-eabi-gdb
- Standard(Linux)
- Version: mi
- Use remote target
