This page describes setting up a simple programming environment for the STM32F401RE nucleo board on a linux system.
The following steps yields an environment for coding with your text-editor of choice be it vi, emacs, gedit or notepad, and compiling from the terminal with make.
- Download the gcc-arm-none-eabi cross-compiler. Unzip to a directory, and add the compiler to path by adding this line to .bashrc:
- Download and unzip the standard peripherals library (SPL) for the STM32F4.
- Set the correct HSE-value in:
On the nucleo F401RE that I have X1 is 8.000MHz, so I would change HSE from 25000000 to 8000000.
- Download the TCD1304-driver firmware for the Nucleo F401RE and unzip to the directory the SPL unzipped to.
Copy the entire directory for every new project to ensure the MCU’s clock doesn’t get messed up. Don’t forget to edit the makefile in case you add or remove .c files in the src directory. Notice that as of sep. 10th 2016 the STM32F401RE clock settings have been updated, notably the timer clocks which are now 84 MHz before prescaling.
