To build the firmware, there is few thing you need to have.
First, Fetch ChibiOs and some third party contributions with git submodule update --init --recursive.
Install Perl dependencies (used to generate board.h file from board.cfg):
sudo apt update
sudo apt install libc6:i386 libncurses5:i386 libstdc++6:i386
sudo apt install libmodern-perl-perl libxml-libxml-perl
sudo perl -MCPAN -e 'install String::LCSS'
Install GCC for ARM:
Fetch the latest version from https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads.
Extract it to /usr/local (or anywhere you want).
Make a symbolic link to it (adapt the command with the right version name):
cd /usr/local
ln -s gcc-arm-none-eabi-7-2017-q4-major gcc-arm-none-eabi
Add it to your $PATH by adding this line either in your ~/.profile or ~./bashrc:
PATH="$PATH:/usr/local/gcc-arm-none-eabi/bin"
Install STM32CubeMX
Download and install SMT32CubeMx with admin rights (need to signup on st.com): http://www.st.com/en/development-tools/stm32cubemx.html.
Make sure it is installed in /usr/local for linux users (not in your $HOME) or C:\Program Files for windows users.
Edit udev rules for Black Magic Probe
If you are using the nucleo with black magic probe, install the udev rule :
sudo cp 49-black_magic_probe.rules /etc/udev/rules.d/
and update them with :
sudo udevadm control --reload-rules && sudo udevadm trigger
Build
To build the firmware, go to software/embedded then run make.
To flash the firmware, copy paste the .bin generated file to your nucleo.
If your nucleo StLink has been flashed with BlackMagicProbe, run make flash.
