STM32H755ZI-Q NUCLEO Board Inaccessible After Enabling Secure Memory Area

I am working on a secure bootloader implementation for the STM32H755 microcontroller using the NUCLEO-H755ZI-Q development board.I am facing an issue where the MCU has become inaccessible after configuring the secure memory area through option bytes.

Writing to backup registers causes problems with the wake-up timer.

Here’s the situation. The system is built on the STM32WB5MM with basic code written using FreeRTOS. All works well, so now I add the BLE HeartRate application. If I prevent my code from running using a while (1) [ osDelay(10); } loop, the STM BLE Too

X-CUBE-CRYPTOLIB V5.x.x – Thread safety and reentrancy confirmation

Hello ST team,In a previous discussion, @Jocelyn RICARD confirmed that X-CUBE-CRYPTOLIB V4.x was not reentrant, partly due to its use of the CRC hardware peripheral.I understand that V5.0.0 no longer depends on the CRC peripheral, but I could not fi

STM32L052 random TIM2_CR1 register reset

Hi there,I’m using STM32L052 for PWM generation with TIM2.TIM2->CR1 is initialized once at start of the program and never touched again during runtime:TIM2->CR1 = 0x00000081;Even though, in some random cases TIM2->CR1 switches back to 0. How

Threadx USBX audio thread and peripheral thread

I’m trying to get two threads running, one that changes audio volume based on a rotary encoder input and one that actually pipes the music to the speaker. I am able to get both working independently with good audio on the audio thread, but I cannot g

How to develop an external flash loader for IS25WX01G memory using the EMM custom driver on STM32N6

published in STM32 MCUs

SummaryIn this article, we go through the steps to create an external flash loader for the external NOR flash memory IS25WX01G. We use the custom driver of the external memory manager, which was first introduced in STM32CubeN6 version 1.3.0.The fully

STM32H723 .. 735 at 1.8V (because of HyperRam)

Heyho,just when we got the quote from our PCB assembly company for a prototype of a big board with the STM32H733, I find that basically all HyperRam ICs with 3.3V are EOL. There’s no alternative to 8-pin HyperRam due to IOs, routing, and board space,
