Hardware

The files made by ST and ARM are hardware-specific, and should be checked and modified before running this yourself.

The driver files should work with most, if not all, STM32 devices (I have not verified this, though I believe they are all relatively similar in terms of how they function, though they still may require some modification). You will of course have to ensure all the pins and GPIOs are set correctly.

Setup

Ensure you are using a correct .ld file for your target hardware, and have also set the correct hardware options in Makefile. Then simply run make in this directory, which will create a file named main.elf. You should then flash this file to your hardware.
