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!This function was defined and used instead of memset to reset mbedtls's sha256 context. Is there a good reason behind this choice?https://github.com/STMicroelectronics/STM32CubeH7/blob/master/Middlewares/Third_Party/mbedTLS/library/templates/ha...
I've written a flash-based bootloader for the STM32F4 using the latest STM32CubeMX tool and its HAL libraries. I've avoided all the usual pitfalls (it's not my first bootloader), and my code works reliably. I'm not erasing my bootloader segment, writ...
I'm working on RTC smooth digital calibration on an STM32U575 board using the HAL function HAL_RTCEx_SetSmoothCalib(). I'm using the LSE (32.768kHz) as the RTC clock source.What I'm trying to do:I want to adjust a known RTC drift (e.g., 500ms) over t...
Hi,I am using a NUCLEO-G071RB development board. I accidentally erased the original bootloader while flashing a custom one. Is it possible to reflash or restore the built-in bootloader on the NUCLEO-G071RB development board? If so, where can I obtain...
I am having issues when writing a buffer that is declared in the external buffer to an SD card. When I tried to download a bulk file (1.5MB), write failure (f_write returns FR_DISK_ERR) would happen at least once during the download process, but if I...
Hello,An ST employee wrote this article: https://community.st.com/t5/stm32-mcus/how-to-use-the-stm32n6-in-overdrive-mode/ta-p/810926where you can increase the voltage to the STM32 core to get higher performance. I have 3 questions regarding this art...
Hello ST Community, I’m working with the NUCLEO-H533RE. The MCU is feature-rich (three PLLs, robust comms, and onboard USB wired to a USB-C connector) and I’m running the system clock at 250 MHz. I’ve migrated the project to ThreadX (since the old US...
Hello,I'm wondering if Cube's generated code for is thread safe. In particular, whether malloc can be safely used in a multi-threaded FreeRTOS setup.The broken malloc behavior was first described by Dave Nadler in 2019 here. He has also written about...
Does the STM32N657 run AzRtos / threadx / filex / etc? The libraries don't seem to be available in the latest IDE. Is this coming soon?
I'm trying to build a simple HTTP server using Mongoose with the LWIP IP stack on FreeRTOS CMSIS_V1. It is important that I let LWIP handle the network interface since I'm also using it to advertise a service using mDNS. This is what my task looks l...
