STM32CubeIDE (MCUs)

When using SPI LL API on STM32H7, we want to use the CFG2[AFCNTR] bit. When “Master Keep IO option”  is used in the IDE, Cube does not generate the LL_SPI_EnableGPIOControl() function call so that the bit remains unset. This has then has to be called from the user code. Is this a known behavior or a bug?Reproduction steps are simple, when HAL is used for the SPI initialization the bit is set correctly, while when it is changed to LL, it is not set. Reproduced on: Nucleo-H723ZGSTM32CubeIDE: 1.19.0Package: H7 1.12.1

Hello, I purchased a new board, the NUCLEO-H753ZI-Q. I flashed it twice successfully, but after the third attempt, it is showing target not found.

Hello,I bought a Nucleo-H7S3L8 and I'm trying to build and execute the XIP_Template and I'm following the official guide.at first I built the Appli project and I choosed the first debug option and got the following error.to solve it I found a post in the community and followed the guide there and changed the config of the "Template_XIP_Appli Debug" and added an External Loader "MX25UW25645G_NUCLEO-H7S3L8-XSPIM1.stldr"and also "MX25UW25645G_NUCLEO-H7S3L8-XSPIM1.stldr"  but got this error instead  what is confusing to me is that there is now to debugging options and the first one have this External Loader"Template_XIP_ExtMemLoader.stldr" but the second was  I didn't found any other solutions and the project could not be debugged or uploaded to the Nucleo Board , can anybody help or give me some tips?

Hi,After CubeMX auto-code generation, CubeIDE shows message: " project XXX is part of hierarchical structure. Would you like to import entire project structure? Yes/NO?  "if I choose "Yes", a sub-directory will be created inside my project which is not desirable. How to fix it?Thanks,Peter

I generate project for g431 in STM32CubeIDE Version: 1.19.0 and HAL generated code is setting PLLCFGR correctly but switching to LL values are not entered.Code generated for LL below:/** * @brief System Clock Configuration * @retval None */ void SystemClock_Config(void) { LL_FLASH_SetLatency(LL_FLASH_LATENCY_4); while(LL_FLASH_GetLatency() != LL_FLASH_LATENCY_4) { } LL_PWR_EnableRange1BoostMode(); LL_RCC_HSE_Enable(); /* Wait till HSE is ready */ while(LL_RCC_HSE_IsReady() != 1) { } LL_RCC_PLL_ConfigDomain_SYS(LL_RCC_PLLSOURCE_HSE, LL_RCC_PLLM_DIV_2, 85, LL_RCC_PLLR_DIV_2); LL_RCC_PLL_EnableDomain_SYS(); LL_RCC_PLL_Enable(); /* Wait till PLL is ready */ while(LL_RCC_PLL_IsReady() != 1) { } LL_RCC_SetSysClkSource(LL_RCC_SYS_CLKSOURCE_PLL); LL_RCC_SetAHBPrescaler(LL_RCC_SYSCLK_DIV_2); /* Wait till System clock is ready */ while(LL_RCC_GetSysClkSource() != LL_RCC_SYS_CLKSOURCE_STATUS_PLL) { } /* Insure 1us transition state at intermediate medium speed cl

I've got a project that's being developed using STM32CubeIDE  V 1.18.1I've switched from using HAL to LL for the RCC, but the stm32g4xx_ll_rcc.c file is not being added to the project (though stm32g4xx_ll_rcc.h is added) - which means that calls to LL_RCC_DeInit() result in a link failure.

#include <stdint.h> #if !defined(__SOFT_FP__) && defined(__ARM_FP) #warning "FPU is not initialized, but the project is compiling for an FPU. Please initialize the FPU before use." #endif int main(void) { /* Loop forever */ for(;;); }Good morning, today, as always I turned on CUBEIDE and started a blank project, however, i do not get the IOC file and have this code in my main, it is the first time i get this, what should i do to get a blank project normally initialised with an ioc file as always?

I am using the  CubeIDE version(1.19.0), I am not able to download the latest N6 MCU packages(1.12) ,its showing check connection error only for N6 series ....

hi i have been trying to configure mcu of h745BIT3 208 pin, IOC file is not generating, and i have tried for g4 series same issue happening today only, is there any server down or update have to do.  regards,srinath

Hello,  I am using STM32F103 and CubeIDE software for a time measurement project. In the capture interrupt function of the external signal, I obtain the value(CNT) of the timer to calculate the interval time between signals. And I use STLINK V2 to debug my program (SWD).  While I was debugging my program, I found that no matter where I add the break point, the interval time would change. In other words, the process of adding breakpoints during debugging affected the operation of timer. This does not occur in Keil. Please provide me with a solution. Because I don't want to give up using CubeIDE.   

Why NUCLEO-64 STM32F411RE EVAL BRD not in the target list, only STM32F411E-DISCO ?I have STM32CubeIDE_1.19.0 and updated STM32CubeMX 6.12.0. and have restarted PC.

Hello,I am working on a project that requires the code to be stored in the external QSPI flash but the problem is, I have no idea how the external memory loader generated by CubeMX works. I have tried following this article, but the external loader link is broken. Can someone please answer the questions below?How do you program the external memory with the application project?How can I configure the external memory manager to work with quadspi flash? I am guessing I need to write my own drivers for the external flash but where do I put this? Regards

Hi, Project can't be built - CubeIDE Window → Preferences → C/C++ → Build → Environment list is empty.   My CubeIDE 1.18.0 was working fine for many weeks with Nucleo-H753ZI board and CubeMX.   Two days ago, it stopped working after I upgraded it to version 1.19.0. The screen stayed in IDE home window.  Then   1, I deleted directories below      C:\ST\STM32CubeIDE_1.19.0       C:\Users\User\STM32CubeIDE       C:\Users\User\.eclipse        C:\STM32\Workspace   2, I Installed STM32CubeIDE 1.18.0 as administrator.   However, the project can't be built. I found -  1. Window → Preferences → C/C++ → Build → Environment list is empty.  2. .C:\Users\User\.eclipse is missing.- was not regenerated.   I repeated the above steps to install 1.19.0 as administrator.

In an IDE makefile project I use a linker script which is created in the pre-build step. In v1.12 of the IDE it worked fine. Now I have to use 1.16.1 and now make complains at the linker step that it has no rule to create the linker script. Well, make is correct that there is a dependency on this file, but it should just accept the file which is already there. The actual build rule is in the pre-build step, which make does not "see". How can i configure the project so that make "knows" that he linker script is here and up to date? 

Hi all,I use the STM32CUBE IDE (version:1.18.1) on windows 10. I can not create a normal stm32 project recently, because CUBEIDE cannot generate the .ioc file.（a) Abnormal code architecture(b) Normal code architecture(reference)If you know how to handle this, thank you very much for telling me.

Split from stm32 targeted project type is empty and its not generating .ioc file as it's not the same issue Im facing the same issue and couldnt open the IOC files, is there any other options to make it run 

Hello,I’ve configured SPI in CubeMX with DataSize = 12 bits. However, when I use the HAL function HAL_SPI_Transmit, the pData argument seems to require a uint16_t (or at least 16-bit aligned) buffer.I'm a bit confused about how this works in practice. Since I'm sending a 16-bit word, but only configured 12-bit frames, does the SPI peripheral transmit just the lower 12 bits of each word? Or do I need to pack the 12-bit values differently?I'm still fairly new to STM32 development, so I appreciate any clarification you can offer!Best regards,Kewin

I am trying to connect the STM32L475E-IOT01A board to Azure IoT Hub using the inbuilt Wi-Fi module, and I'm working within STM32CubeIDE.I found the official example project iot-middleware-freertos-samples, but it uses CMake, while I need a similar example implemented directly in STM32CubeIDE.I have already configured the Wi-Fi module in CubeMX, but I need help understanding:Which libraries are required to add manually in STM32CubeIDEHow to port or adapt the CMake-based example into an STM32CubeIDE projectAny guidance, example projects, or documentation would be greatly appreciated.

Hi everyone,I'm working on programming the B-U585I-IOT02A board for my Master's thesis in Computer Engineering. My goal is to continuously record audio samples using the onboard microphone, then convert them into spectrograms and analyze them using AI. Unfortunately, I'm having trouble setting up the microphone. I can't find any reference projects online for audio recording on this board, and I'm currently stuck. My original plan was to use DMA with its callbacks (HalfTransfer, TransferComplete), but I'm not sure how to properly configure the microphone or which peripheral I should use to capture the audio: MDF1, ADF1, or SAI1? How do I then link DMA to one of these peripherals to trigger the appropriate callbacks? Which pins should I enable in the .ioc file, and in which mode, to make everything work correctly? Any suggestions or references to similar projects would be greatly appreciated. Thanks in advance!

Hi,I am quite new to using CubeIDE. I compiled and ran my first program and the below is the response from the IDE:>>>>>>>>Erasing memory corresponding to segment 0:Erasing internal memory sectors [0 6]Download in Progress:  File download completeTime elapsed during download operation: 00:00:00.587   Verifying...    Time elapsed during verifying operation: 00:00:00.048  Download verified successfully   Target is not responding, retrying...Shutting down...Target is not responding, retrying...Target is not responding, retrying...Target is not responding, retrying...Target is not responding, retrying... <<<<<<<<< This seems to me that the program was properly downloaded to the board and then verified. Why is it then reporting that the target is not responding? Regards
