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...
Hi,I am experiencing a core freeze issue on STM32H7S3L8 MCU, as described below.UPDATE 1: Most probably Data Cache is the main culprit, closing Data Cache in bootloader solves the problem. Application code Enables Data Cache and we have never observe...
Hello,I am currently using an STM32U5G9 and would like to connect a microSD card via SDMMC1 to expand data storage. My Zephyr devicetree contains the following node:&sdmmc1 { status = "okay"; pinctrl-0 = <&sdmmc1_d0_pc8 &sdmmc1_d1_pc9 &sdmmc...
Hi. I'm having trouble using the old USB Host Middleware to read a USB stick with a STM32U545.I've tried to follow this article, doing my best to adapt it for the host middleware and also using the "FatFs_USBDisk" example project for the F767 Nucleo ...
Hi all, I've recently been working on a Nucleo H723ZG with a working implementation that allows for ADC reading over DMA. I've got a Timer event that triggers it at 20kHz and it was reading and processing multiple ADCs. I've shifted to using a custom...
Hi,We're working on integrating the STM32N6 Getting Started Object Detection and the VENC SDCard examples and were wondering if we could ask some advice on memory allocation?The Object Detection example defines AXISRAM1_S and I think uses this for th...
Hi all, I am working on an STM32H755 project using external QSPI NOR Flash.I intend to use the QSPI Flash in two different ways: 1. Memory-mapped mode for read-only resources (UI assets, fonts, images, etc.)2. Indirect mode for file system operations...
I created project in stmcube32mx for h5 microcontroller and it works if I manually replace bl main to bl entryin file startup_stm32h563zitx.s.If this manual replacing is a bug or on purpose?Jan
Get early access to the next-generation STM32Cube HAL drivers for STM32U5A major update to STM32Cube HAL drivers, called HAL2, is now available for preview on GitHub. It supports the STM32U5 series. Building on over 10 years of experience, HAL2 deliv...
When using a USB CDC device, especially at high data rates, there is a possibility for packet loss. This post illustrates the issue with what I consider convincing evidence. This isn't a STM32 bug, but it's something you may encounter when interfacin...
Hi. Unfortunately, after several days of struggling with USBX, I'm forced to ask for your help. I'm using custom boards with the STM32h503RB and STM32h563VI. I tested the old library according to forum guides – no response when connected to a PC. The...
