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’m working on an STM32G491 MCU and facing an issue with GPIO PB9.In my project, I initialize PB9 as a digital output and try to set it HIGH, but the pin always stays LOW on the board.However, if I configure PB9 as input and toggle the pin extern...
Hello ST Team,I am using an STM32H755ZIT6 where CM7 handles a high-speed Quad-SPI flash interface with 100Mhz and UART communication with flow control 115200 baud.The same firmware runs on two hardware revisions:Revision V2: Works perfectlyRevision V...
I am trying to get this sample working on my STM32 Nucleo F767ZI board:zephyr/samples/drivers/uart/async_api/I created an overlay file.nucleo_f767zi.overlaydut: &usart3 { dmas = <&dma1 2 STM32_DMA_PERIPH_TX>, <&dma1 3 STM32_DMA_PERIPH_RX>; dma-names ...
I'm curious how hard of a task would it be to get UCPD working with the STM32N6 with zephyr. I see it's supported with the G0* https://docs.zephyrproject.org/latest/boards/st/stm32g071b_disco/doc/index.html From my understanding the UCPD hardware blo...
Hello Everyone,I designed pcb while to use STM32H723VGT6. I used an Ethernet phy called DP83848 to communicate via Ethernet.I have previously used this Ethernet phy with F4 series processors and communicated via Ethernet without any problems. I am us...
Hello, I am working on a project using DMA and UART HD to communicate between multiple MCUs. I have an issue where when one MCU starts up, it momentarily interrupts the UART HD bus and sometimes causes a UART and/or DMA error.Since I am using the ST...
Hello,I am new to STM32F746-Disco and I was trying to develop an application starting from TouchGFX.It went all good in developing a touchGFX app and use the generated .ioc and so on to configure a project but I've tried afterwards to configure the e...
I am working with Zephyr RTOS on the Nucleo-H7S3L8 board and have successfully flashed and run the blinky example on internal flash. However, I noticed that Zephyr does not provide official documentation for flashing applications into external flas...
stack:Zephyr on stm32n6 (nucleo_n657x0_q)When sending a buffer over sai via i2s_write data is written into the buffer.I expected the TX buffer to be treated as read-only and remain unchanged by the driver.It's only ever the first 2 numbers.Why is tha...
Hi everyone, I'm encountering an issue with the STM32H747 dual-core MCU during the transition from bootloader to application. Here's a summary of the setup and observed behavior: Setup: Bootloader (CM7 core): When the BCM4 option byte is enabled, the...
