STM32F401VET6 flash partition to store 3 binary files at particular flash addresses. These binary files need to be used for some product applications.

We have STM32F401VET6 in our product development. Currently, our project (makefile) compiles and stores application binary in STM MCU internal flash. We would like to store three other binary/hex files to the STM MCU internal flash as part of the bui...

Retrieving multiple SPI packets from DMA

Hi guys I have set up my STM32 as an SPI full duplex slave device. All SPI communication happens through DMA. The Master device is a Beaglebone Black communicating over linux spidev driver. The problem I am facing now is if the master sends multiple ...

Cannot get printf via USART to work on STM32H745

Hello!As the title says, I haven't managed to get the printf function to work on my STM32H7 MCU. I am using the Nucleo-H745ZI-Q with STM32Cube MX and Keil. Here is the code I'm using:#include "stdio.h"   /* USER CODE BEGIN 0 */ #ifdef __GNUC__ #defin...

How Is "system_stm32xxxx.c" File Included?

I'm having a brain fart and can't figure this out. I'm porting an existing project from the STM32F205 series to the STM32L496 series. So I replaced "system_stmf2xx.c" with "system_stml4xx.c" in my project workspace, but my compiler (IAR) isn't pickin...

High level at the outputs of PA9 and PA10 after reset. STM32G030K8

After resetting, the output of PA9 and PA10 of the STM32G030K8 microcontroller is high. These pins are not initialized, according to the datasheet after reset they should have the function of an analog input. Once configured, they function normally a...

STM32H745 FMC acces to external NOR with timing from RM0399 does not work (works only with burst, but not non-burst)

Hallo,I'm using a STM32H745, that shall access an external NOR flash with the timing recommended by ST at the reference manual RM0399 on page 875.  I did exactly reproduce this timing setting, but no access will be generated on the FMC pins.When I ch...

Hello, I am using the STM32CubeG4 SDK to create a new project. The problem is that while there are some linker scripts provided for the IAR compiler, I cant find any for the GCC. The same applies to other SDKs Where can I find these linker scripts?

Very strange byte write on external 16 bits SDRAM

Hello, I need help with my external SDRAM I try lot of thing like use discovery board (STM32F769i) with a SDRAM on 32 bits and when I try 16 bits or 8 bits all is ok work like a charm.My custom board have a STM32F779 with 16 bits ram.My issue is that...
