How to debug STM32N6 using STM32CubeIDE
Summary This tutorial is a comprehensive guide for debugging code from external serial flash on the STM32N6. It covers: setting up the environment, configuring the debugger, and validating the setup. Introduction To debug the code running from the e...
How to use HASH with DMA in byte transfer mode on STM32H5: why DMA DATA PACK matters
Introduction The STM32H5 microcontroller family integrates hardware HASH peripheral capable of computing MD5, SHA-1, SHA-224, and SHA-256 digests, which can be efficiently supplied with data using DMA. In many real-world applications, input data is n...
STM32 in dual CAN configuration: bxCAN Filter bank explanation and relation with CAN2 Start Bank parameter
Introduction STM32 MCUs users may face an issue with CAN message reception mainly when the CAN2 instance is used. This issue may appear even if the hardware setup is correct, and CAN bit time and filters are configured correctly. If the value of Sta...

Summary This article is an introduction to STM32 MCU development through the VS Code IDE using the updated STM32 Visual Studio Code extension v2.0.0 or newer. In this article, we cover the following: Downloading the updated VS Code ExtensionCreating ...
STM32 AES byte ordering: Why your encryption/decryption output doesn't match the test vector
Introduction When STM32 AES encryption or decryption output doesn't match the expected test vector, the instinct is to immediately question the key, mode, or algorithm. In many cases, the real issue is more simple: the bytes are correct in memory, bu...
STM32H7RS series lifetime usage estimation
This article presents estimated lifetime usage for STM32H7RS series microcontrollers. These estimates are qualified based on the product mission profile, which defines the available lifetime of the product under a specific set of conditions. These c...
How to create and run a minimal AES-GCM DMA example on STM32C5 using STM32CubeMX2
Introduction This article describes, in a practical and end-to-end manner, how to create and run a minimal AES-GCM example using DMA on an STM32C5 device configured using STM32CubeMX2. The goal is to provide the source code and document the full wor...
FAQ: STM32 SRAM/Backup SRAM content is not preserved after reset
Problem Backup SRAM or normal SRAM content is not preserved after reset or wake up from standby. After a reset, the last few bytes written are not kept. Solution This issue appears on STM32 devices that have ECC (Error Code Correction) on internal ...
How to calculate and generate post-build CRC
1. Cyclic Redundancy Check Cyclic Redundancy Check (CRC) is an error detection method for digital data based on binary division.CRC algorithm generates a fixed checksum code length. 2. How to calculate and generate post-build CRC? Post build CRC ar...
