Summary This article allows the process to regress from RDP 2 to RDP 0 on the STM32U5 series. This example uses the STM32U5 Nucleo board with STM32U5A5ZJT6Q and STM32CubeProgrammer V2.13.Note:To regress from RDP2 to RDP0, you must be sure that your ...
What is the ST product longevity commitment program? The ST product longevity program is a formal commitment by STMicroelectronics to ensure the long-term availability of ST products for a defined period of 7, 10, 15 or 20 years. STM32 product longev...
Summary In the STM32H7 dual core series (STM32H745/755 and STM32H747/757), some resources are shared and must be initialized only once. This is notably the case for the clock tree. For this purpose, one core waits while the other performs the necessa...
Summary This article provides a detailed guide on using VS Code to debug code running from external serial flash on the STM32N6. It covers setting up the development environment, setting up the project with CMake, configuring the debugger within VS ...
Introduction In the field of embedded systems, it is very common to migrate an existing design from one STM32 microcontroller to another in response to changing application requirements. These changes can be dependent on, for example, flash memory, S...
Summary This article examines cache coherency issues specific to STM32 high-performance microcontrollers, describes the reasons behind their occurrence, and outlines how the memory protection unit (MPU) serves as the primary tool for configuring memo...
We understand that many of you are experiencing difficulties integrating the STM32 extension into the Dev Container environment. Specifically, the extension is not functioning correctly due to a dependency issue message displayed in VS Code. This pro...
Summary This article shows how to integrate Mbed TLS with hardware acceleration offloading benefiting from embedded hardware crypto engines (AES, PKA, HASH). Introduction The STM32H5 series is a powerful microcontroller family that benefits from ha...
Summary To understand how middleware like NetXDuo and LwIP use the STM32 HAL Ethernet driver, this article demonstrates a bare metal application to send and receive Ethernet frames. If you are not interested in following the step-by-step tutorial you...
Summary This article presents a tutorial for importing and using the legacy STMicroelectronics USB middleware in the new lines of STM32 to implement a CDC class to open a virtual COM port. The STM32H5 series was selected for this tutorial, but the st...
