Start with stm32 in Ubuntu 20.04

Dependencies / Softwer

• Install libusb - userspace USB programming library development files
• Install stlink - open source toolset to program and debug STM32 devices and boards
• Install GNU Arm Embedded Toolchain - is a ready-to-use, open-source suite of tools for C, C++ and assembly programming
• STM32-Template - according to Geoffrey Brown stm32 template
• Standard Periheral Library - the Library includes a complete register address mapping with all bits, bitfields and registers declared in C a collection of routines and data structures covering all peripheral functions (drivers with common API)

Install libusb

ubuntu@ubuntu:~$ sudo apt-get install libusb-1.0-0-dev

Install stlink

There are two possible ways described how to install stlink, e.g.:

• using .deb package
• from source

Install .deb package

Download and install .deb package using Software Center. Another possible way to install stlink is described in section below.

Install from source

Install stlink into folder /opt

ubuntu@ubuntu:~$ cd /opt
ubuntu@ubuntu:~$ git clone https://github.com/texane/stlink.git
ubuntu@ubuntu:~$ cd stlink
ubuntu@ubuntu:~$ make clean
ubuntu@ubuntu:~$ make release
ubuntu@ubuntu:~$ make install

Install / Copy stlink rules

// install udev rules
ubuntu@ubuntu:~$ sudo cp etc/udev/rules.d/49-stlinkv* /etc/udev/rules.d/
// restart sudo restart udev
ubuntu@ubuntu:~$ sudo udevadm control --reload
// using this command no need to disconnect and connect device
ubuntu@ubuntu:~$ sudo udevadm trigger

Troubleshooting

// error message
st-info: error while loading shared libraries: libstlink.so.1:
cannot open shared object file: No such file or directory.
// solving
ubuntu@ubuntu:~$ sudo ldconfig

Install GNU Toolchain

The GNU Arm Embedded toolchain contains integrated and validated packages featuring the GCC compiler, libraries, and other tools necessary for bare-metal software development.

Download and extract GNU Toolchain. Then copy extracted files into folder /opt/gcc-arm:

ubuntu@ubuntu:~$ sudo cp -a /home/<your name of home directory>/Downloads/<Extracted GNU Toolchain package>  /opt/gcc-arm

Structure of folder /opt/gcc-arm should look like:

• arm-none-eabi
• bin
• lib
• share

Create symbolic links

ubuntu@ubuntu:~$ sudo ln -s /opt/gcc-arm/bin/arm-none-eabi-gcc /usr/bin/arm-none-eabi-gcc
ubuntu@ubuntu:~$ sudo ln -s /opt/gcc-arm/bin/arm-none-eabi-ar /usr/bin/arm-none-eabi-ar
ubuntu@ubuntu:~$ sudo ln -s /opt/gcc-arm/bin/arm-none-eabi-as /usr/bin/arm-none-eabi-as
ubuntu@ubuntu:~$ sudo ln -s /opt/gcc-arm/bin/arm-none-eabi-objcopy /usr/bin/arm-none-eabi-objcopy
ubuntu@ubuntu:~$ sudo ln -s /opt/gcc-arm/bin/arm-none-eabi-size /usr/bin/arm-none-eabi-size

Trobleshooting

// error message
arm-none-eabi-gdb: error while loading shared libraries: libncurses.so.5: 
cannot open shared object file: No such file or directory
// solve
ubuntu@ubuntu:~$ sudo apt-get install libncurses5
