To answer the questions like "Is my ST-Link/V2 genuine? Where to find a genuine ST-Link/V2? Why my device isn't recognized?" and other related ones, please refer to the following: Where to find a genuine ST-Link/V2 ST-Link official in-circuit debugge...
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...
The problem is related to two things: memory layout on STM32H7 and internal data cache (D-Cache) of the Cortex-M7 core. In summary these can be the possible issues: Memory placed in DTCM RAM for D1/D2 peripherals. Unfortunately this memory is used a...
This article explores the methods of safeguarding your code from unauthorized external access in the STM32H5 series. It delves into the new "Product State" feature, which functions similar to the readout protection (RDP) feature available in other ST...
Introduction This article describes how to debug in external memory on STM32CubeIDE based on the example provided in the following GitHub repository: STM32CubeH7/Projects/STM32H7B3I-EVAL/Applications/ExtMem_CodeExecution.Regarding hardware, we use th...
How to find the RAM ECC failing address? How to access to the right RAMECC monitor to get the RAM failing address when an ECC error occurs?How to translate the content of the failing address register to the actual RAM address (e.g. FADD= 0x2004)? No...
Ethernet reference clock affecting ADC values in STM32 microcontrollers In various STM32 microcontroller applications, the Ethernet reference clock (ETH_REF_CLK) has been observed to introduce noise into ADC (analog-to-digital converter) measurements...
There are two possible solutions for connecting two quad-SPI memories using only one OCTOSPI interface. Solution 1: Use a dedicated bit in the OCTOSPI_CR register for external memory selection: MSEL bit for STM32H5, STM32U5, and STM32L5 series or FS...
The Ethernet peripheral on STM32H7x3 is not sending, or receiving data correctly. Or, the IP stack is not able to establish connection to other devices. What could be the problem? In most cases, the problem is related to memory layout and Memory Prot...
Summary and problem description The STM32WL55 is a dual-core, low-power microcontroller with a sub-GHz radio that is connected internally through SPI. Note that whenever "radio" is mentioned in this article, it relates to "sub-GHz radio". To enhanc...
The bootloader inside STM32 families uses the protocol described in AN3154. It is supported by the STM32F1, F2, F4, F7, L4 series. The purpose of this article is to give a guide on how to connect to a STM32 CAN bootloader Target, to erase and program...
1. Introduction Optimizing power consumption is one of the biggest challenges when designing an MCU based application.In this article we selected the STM32F401 MCU that can be configured in four different modes: Run mode, Sleep mode, Stop mode and St...
Introduction For those developing applications that use low power modes, trying to achieve the current consumption numbers listed in the datasheet and performing general debugging can be troublesome. The purpose of this article is to give an overall...
Maximum FIFO size with the OCTOSPI interface The FIFO is sized into the targeted product, typically either 32 or 64 bytes depending on the product. Refer to the reference manual to check the maximum size in the "FIFO and data management" section. Co...
The STM32H7 MCU family clock reaches up to 600MHz and thermal management matters due to power dissipation, see details in the AN5036 Guidelines for thermal management on STM32 applications. https://www.st.com/resource/en/application_note/an5036-guid...
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...
