Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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...
Hello ST Community,I'm working on an STM32H753VIT6 project and need to upgrade FreeRTOS from v10.3.1 to v11.2.0 due to cybersecurity requirements. I've encountered several integration challenges that I'd like to share and seek guidance on.BackgroundC...
Hi All,I am quite new to bootloaders and I wanted to understand best approach to upgrade the firmware. I will get the firmware from a 4g module and store it in external flash. We are based on STM32U5A5 mcu and it will always use the application prese...
It seems there's a bug in the HAL library causing data bytes to be mixed with memory address bytes when sending data using HAL_I2C_Mem_Write_IT function. The issue was observed on STM32L162VET6 while using I2C as master at 300kHz speed. It is caused ...
Hi everyone,I’m working with an STM32H7S3 microcontroller and an external Octo-SPI NOR flash IS25WX064 from ISSI (datasheet: https://www.issi.com/WW/pdf/25LX-WX032-064.pdf)My goal is to get this memory working with ExtMemLoader (including XIP support...
Hi, I use STM32H7 with STCUBE 11.1.I use RNDIS module usbd_cdc_rndis.h to communicate with a PC.Sometimes when the PC sends a frame the STM32 replies with NAK, here is the sequence that repeats:SYNCPID OUTAddressCRCEOPSYNCPID DATA0data 30 bytesCRCEO...
Hello ST Community, I am working on an STM32N6-based board and trying to expose an onboard SD card (SDMMC2) as a USB Mass Storage (MSC) device using FileX and ThreadX. The intended behavior is:When a USB Type-C cable is connected to a Windows PC, the...

Hi,I'm currently working on a project using an SMT32G474RET6. We have the X-Cube-STL with us and trying to integrate it into our project. We have followed all the steps as mentioned in the document and we are able to run the test for our software, bu...
Hi! I am trying to do a simple communication between nucleo-f411re and nucleo-h753zi board using uart communication. but i am unable to set it up. Is it possible? If yes, what is the easy way to do that. How the connections and wiring look like?
Hi,In the GPIO interrupt configuration, the port information is ignored and only the pin number is used for identification. As a result, pins with the same pin number on different ports cannot be enabled as interrupt sources at the same time. stm32_g...
