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,I am planning to build a cellular application using EC200 as my modem. I prefer to use in modem stack using AT commands due to memory constraint of my MCU. I have come across X Cube Cellular where it is mentioned this setting can be changed usi...
Hello, I have made my own STM32F732RET6 board that has a USB FS configured as a Stereo, 24 bit 48kHz Audio Interface and SAI2 connected to an SN75176BDR (Differential Bus Transceiver IC) because I want to transmit AES3-AES/EBU (same as SPDIF) audio d...
There's a serious bug in G4's hal(version 1.6.1) library in spi dma function.The problem is:1, user calls HAL_SPI_TransmitReceive_DMA2, after spi transmission finished, HAL will call HAL_SPI_TxRxCpltCallback3, user calls HAL_SPI_Receive_DMA inside HA...
Hello,In the STM32CubeC0 v1.4.0, when I enable the BYPSHAD bit in the CR register and later try to deinit the device, I get an ERROR. It does not happen if I disable it before deinitialising. Should I disable it by hand, or is it a mistake and should...
I built a custom application based on the LwIP_HTTP_Server_Netconn_RTOS example in the CubeMX SDK 1.17.4. RX and TX work after power-up and in 50% of cases also after a debugger reset. However, in 50% of cases, RX doesn't work at all. The symptoms in...
Hello,I am working on an STM32F746 project where I have implemented a bootloader.The setup is as follows:Application image is stored in external QSPI flash.Bootloader copies the image from QSPI to SDRAM (IS42S32400F at 0xC0000000).After copying, I se...
Hi, It works, apparently a different microSd card works. however, it is strange that, DATALOG2 could write into the card. May i know how shall i perform sd card format function or what to fill up in the function? Follow-up of the the topic below: S...
Hello,I am developing an embedded project using the STM32H7 microcontroller, integrating FreeRTOS, FatFs file system, USB mass storage device (USB flash drive) functionality, SD card reading/writing,UART communication, and ADC sampling. My system use...
There is no test.txt file in my USB drive after the example is run.The board sends this log**** USB OTG HS Dual_Class Host **** USB Host library started. Starting Application Connect your HID or MSC Device USB Device Enumeration FailureTried to at...
Hello, I'm currently testing a bootloader-XIP application architecture on a NUCLEO-H7S3L8 board. The MRAM (XSPI2) test works perfectly in the bootloader, but when I move the same code to the XIP application, the system hangs during XSPI2 initializati...
