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 all, SynopsisI have just found a severe error in FileX that looks like buffer overrun in fx_file_read(), but the problem is much deeper. This function leads to the function sd_read_data() which when invoked with use_scratch_buffer = 0 reads sector...
Hello,I'm working with STM32H745ZITX on a dual-core setup. I configured USART3 on the CM7 core. The communication flow is:TX: Using HAL_UART_Transmit (polling)RX: Using HAL_UART_Receive_ITThe first message reception works correctly. The HAL_UART_RxCp...

Hello everyone, I am using a custom board with STM32H750 and I am trying to develop a file system with FILEX. The file system' s media is a uSD card with 10 MB/s baudrate which is communicating with the micro thanks to the SDMMC peripheral. The SDMMC...
I am currently using the v1.6.1 of STM32CubeIDE and a STM32G473 MCU.I have implemented an I2C bus and have noticed a major bug with the I2C_WaitOnFlagUntilTimeout functions. There is this condition:if (((HAL_GetTick() - Tickstart) > Timeout) || (Time...
Hello,I'm slowly losing my sanity so I figure I'd make a post here. I set up SAI4 to interface with BDMA, hoping to retrieve data from the onboard MEMS microphone and store it in a buffer in RAM_D3. Ideally I'd like for that data to be processed by t...
Hello,Working on STM32F767BITx and using Free RTOSEnable USART2, here is the init codestatic void MX_USART2_UART_Init(void) { huart2.Instance = USART2; huart2.Init.BaudRate = 115200; huart2.Init.WordLength = UART_WORDLENGTH_8B; huart2.Init.St...
Hi,I'm using an STM32F746G-DISCO board and I'm just trying to build a build a simple project with LWIP and FreeRTOS using CMSIS V2 however after enabling the minimum hardware using CubeMX I am unable to get any ping replies from the board. If I use C...
I am using STM32U5G9 implementing USB MSC device. When calling function ux_device_stack_initialize(), it returns error 18, which is correspond to UX_MEMORY_INSUFFICIENT. This error happens line 397 of use core file ux_device_stack_initialize.c.if (...
Hello everyone,I'm developing an application using USBX CDC ACM class in standalone mode. I've written an execution loop for scheduling USB stack operations and there are no problem with READ transaction; i'm able to receive correctly every data from...
