Welcome back with the part 2 of our article series that explains how to add a custom SPI flash memory in the External Loader portion of the STM32CubeProgrammer and in the STM32CubeIDE. In the first part we covered the pre-requisites and linker scrip...
Summary Recent STM32 series have an interesting feature called readout protection with password. It is possible to configure it using the SWD/JTAG debug interface or within user application code. The theory and an example of the first method is full...
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)? Note: For simplicity and clarity, the descr...
After programming my STM32H7/STM32H7RS and performing a reset, I find that I can no longer connect to my target using STLINK. Why does this happen? How can I recover my board? Note that your STM32H7/STM32H7RS’s SMPS or LDO firmware power configuratio...
Introduction The purpose of this article is to explain how to generate a custom signal, a sine wave in this case, using an STM32 Microcontroller’s DMA controller and a PWM output from a timer. Although this example uses the NUCLEO-H745ZI-Q, the same ...
After updating or installing STM32CubeIDE 1.13.x or STM32CubeMX 6.9.x, you will be asked to connect to your STMicroelectronics account to download the packages. That is why you need to choose one of the following types of proxy server. Use System Pro...
Is there an interface that replies to your need? Yes, it is the PSSI. What does a PSSI stand for? Parallel synchronous slave interface. What the PSSI interface is? A generic synchronous 8/16-bit parallel data input/output slave interface that...
Introduction Debug authentication is a critical security feature of the system considering that with a debugger the user can access a large part of the system. To control a reopening of the debug port, the device imposes a debug authentication proto...
Introduction Clock configuration is a fundamental aspect of microcontroller (MCU) design, directly influencing the performance and power consumption of the system. In the STM32 series, the reset and clock control (RCC) peripheral manages the system...
Summary This article provides an overview of the low-power modes available in the STM32N6 series. It provides hands-on instructions for utilizing the Standby demo, detailing how RAM retention is implemented and how to run the demo code. Introduction...
Summary This article guides readers through locating key information in STM32 documentation, using the STM32G081xB datasheet as a practical example. We illustrate how to identify details about the current sinking capabilities of pins, including the ...
This is the second part of a custom LoRaWAN server tutorial. For the first part which describes up the Network server, please refer to:How to create a LoRaWAN server on local PC(1/2) - Network server Application server Now that the network server is...
Summary This article describes tips to prevent or fix errors encountered when connecting the STM32 target board to your computer such as: “No target connected”, “Target not found”, “No ST-LINK detected”, and “ST-LINK connection error”. Software and ...
Introduction For various reasons, developers may need to deactivate booting of a core in the STM32H7 dual-core product. This article shows how to disable the Cortex®-M7 and Cortex®-M4 cores and enable them again. 1. Disabling a core in a dual-core co...
Summary This article provides a step-by-step guide on how to calibrate the precision of a real-time clock (RTC). The examples in this guide are provided using the NUCLEO-U575ZI-Q board, but can be tailored to any other STM32. Introduction The real-t...
Summary This article provides a quick guide on what the STM32N6’s OTP bits are and how to program them. It includes step-by-step instructions and explanation on configuring the OTP124, responsible for changing the VDDIOs' voltage to 1.8 V instead of...
Defining HSLV HSLV is a characteristic of certain I/O ports that allows them to operate at higher speeds while using lower voltage levels. This feature is particularly useful for applications that require fast data transfer rates without the higher ...
Summary This article provides a step-by-step method to test the ECC single and double errors in the STM32H7 series. Find attached to the article a ECC RAM project for testing purposes. Introduction In STM32H7 microcontrollers, RAM ECC (Error Correc...
Introduction ST and its partners offer software expansion packages that enable the use of specific features or external devices with the STM32 MCU. These can be installed locally and included in projects using STM32CubeMX. This article demonstrates h...
Summary The first stage bootloader (FSBL) requires a header signature for the boot ROM to load the code from the external memory into the internal RAM. This allows the application’s code to begin execution. Creating this header involves the STM32Sig...
