Welcome to the STM32 Arm®Cortex®-based MPUs user guide!

This user guide aims at assisting developers to use STM32 MPUs microprocessor devices from STMicroelectronics, starting with the STM32MP1 series. x100px


It first intends to help developers getting started step-by-step with the boards and discovering the ecosystem for the STM32 Arm Cortex-based MPUs.
Then, with the development zone, it provides developers with many articles to enhance knowledge about the hardware and software for these devices, to discover the ecosystem software tools, and to tune the software through advices and tips for tracing and debugging.
