Specific utilities, such as DDR configuration and tuning, make it easy to get started with STM32 microprocessors. For microprocessors, the second step allows to configure the GPIOs and the clock setup for the whole system, and to interactively assign peripherals either to the Arm ® Cortex ®-M or to the Cortex ®-A world.
The first step consists in selecting either an STMicrolectronics STM32 microcontroller, microprocessor or a development platform that matches the required set of peripherals, or an example running on a specific development platform.
