Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
I am having difficulties with initializing a SD Card.I am making use of the generated code to initialize the card:void MX_SDMMC1_SD_Init(void) I measured with a scope and I am getting 400KHz clock. All the pull-up resistors are correct and voltage is...
Heyy, I'm using an STM32u545 (on a Nucleo board), and I'm trying to wake up my MCU from stop 2 mode using wake-up pin 2. Wake-up pin 2 is connected to LPTIM3 (via a jumper wire), and LPTIM3 works. Besides trying to wake up the CPU. An LPBAM applicati...
Hello everyone,I'm using the stm32G0 USB Host with firmware package V1.6.3.There is an issue with H2D control transfers, where the USB Host stack send a second OUT packet before sending an IN packet on the last packet.I wrote a usb dfu host class tha...

Hi, During the development of a bare-metal driver for USB CDC (virtual com port) in device mode i noticed an unexpected behaviour when trying to configure the USB Core to do a transmission of a multi packet message. I've got the following code which ...
I am running the Analog Devices EVAL-ADE9430 board and noticed if I enable CRC checking reading 32 bit registers fail while 16-bit registers always pass. I trace it down to the AFERead16BitBuffer() function not returning a status after reading the r...
Hi everyone,I wanted to share a project I’ve been building over the last few years. It’s called Mk, an operating system built entirely from scratch for the STM32F746G-DISCO and STM32F746G-Eval2 boards.These boards are powered by an ARM Cortex-M7 run...
Hello, I am working on I3C private transfers. When I build the context buffer with HAL_I3C_CTRL_BuildTransferCtxPrivate I get an assert when IS_I3C_PRIVATE_MODE is checked against HAL_I3C_PRIVATE_WITH_ARB_RESTART. Is the exclusion of HAL_I3C_PRIVAT...
Hello, I am looking for an example of how to use private I3C transfers for STM32C562RE. I read the I3C examples posted on Github but I did not find any controller or target examples that use HAL_I3C_CTRL_Transfer_DMA and HAL_I3C_TGT_Receive_DMA for p...
Recently, I was trying to implement SDMMC+DMA+SDFAT to read and write the SD card of my Class on the STM32H750VBT6. Then I found that the DMA of SDMMC was gone. I saw some online materials saying that MDMA needs to be configured, and some also said t...
