QUAD SPI Communication between two STM32H7 boards

Trying to transmit and receive data between two STM32H7 boards using QSPI.As we are new for using QSPI communication,we generated code using STM32CUBEMX and not able to transmit and receive the data.The screenshots for communication between two contr...

STM32 UART DMA reception fails to update memory buffer from peripheral

Hello ST,I'm using STM32H743ZI. Here I'm connected to 2 external devices(1 for PC UART5 and other for another MCU UART7), both are connected via UART.I'm using DMA with UART7 for receiving data from MCU. UART5 which we use to communicate with PC(Mast...

How to configure OctoSPI in Quad mode with PSRAM for memory mapped write access? Getting Hard Fault (FORCED, IMPRECISSERR) when write is attempted.

Hi there, I trying to configure octospi on STM32H7A3 to work with LY68L6400 PSRAM via quadspi.I have followed AN505 and managed to init, write and read from the memory successfully in indirect mode.Now I am trying to map the PSRAM to memory. I can re...

May I know if there's a new qualification of MSL for STM32F devices from year 2021? particularly on STM32F100. Thanks!

SPI data transmission

Using STM32f3xxx series & using SPI2.I wanted to transmit 32 bits data at atime, but in APIHAL_StatusTypeDef HAL_SPI_Transmit(SPI_HandleTypeDef *hspi, uint8_t *pData, uint16_t Size, uint32_t Timeout) pData is fo r uint8_t.how to transmit uint32?

I'm going crazy, look at the photos: if I move the SWD CLK connection in one point of the breadboard the connection works, in another it doesn't! The chip is a STM32L412KB, I tried to replace it but nothing! I also replaced the ST-LINK but nothing yet.
