STM32 MCUs Software development tools

I'm jumping to the bootloader from my application so that I can flash via USB in the end product.The end product has a permanently connected battery, and other means of hardware reset are not accessible.I'm trying to use STM32CubeProgrammer for this and can successfully connect and flash via USB under the "Erasing and Programming" tab. I have Verify and Run after Programming checked.However after successfully flashing, the MCU hangs and does not jump back to the application.At this point I can't reconnect via USB either in the tool. I do not think a hard reset is done after flashing.CLI is not an option based on the internal users I plan to give this to as a tool.What is the correct approach to make sure I actually get a clean reset and run of my application after flashing with the GUI?

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

Hi,I got the problem on choosing FMC pin definition of STM32N657A0 in CubeMX 6.15.0. As the datasheet said the FMC_NORMUX is supported by the chip, I cannot find corresponding settings in CubeMX as the screenshots.Thanks.

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'm currently hesitant to upgrade CubeMX to version 6.15.0 due to previous issues with Ethernet support. Specifically, I encountered a problem where Ethernet (likely LwIP stack with STM32H7) was not functioning correctly in CubeMX 6.14.1, which forced me to revert back to 6.14.0 where it worked as expected. Before upgrading, I’d like to confirm if Ethernet-related issues have been resolved in 6.15.0. Has anyone verified Ethernet (especially with LwIP and HAL/LL drivers) is stable in this release?

Hello.I'm using a NUCLEO-311RE board.I'm looking for a way to bypass the external waveform as it is.This is my timer setting static void MX_TIM1_Init(void) { /* USER CODE BEGIN TIM1_Init 0 */ /* USER CODE END TIM1_Init 0 */ TIM_SlaveConfigTypeDef sSlaveConfig = {0}; TIM_MasterConfigTypeDef sMasterConfig = {0}; TIM_OC_InitTypeDef sConfigOC = {0}; TIM_BreakDeadTimeConfigTypeDef sBreakDeadTimeConfig = {0}; /* USER CODE BEGIN TIM1_Init 1 */ /* USER CODE END TIM1_Init 1 */ htim1.Instance = TIM1; htim1.Init.Prescaler = 0; htim1.Init.CounterMode = TIM_COUNTERMODE_UP; htim1.Init.Period = 1; htim1.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1; htim1.Init.RepetitionCounter = 0; htim1.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_DISABLE; if (HAL_TIM_Base_Init(&htim1) != HAL_OK) { Error_Handler(); } if (HAL_TIM_OC_Init(&htim1) != HAL_OK) { Error_Handler(); } sSlaveConfig.SlaveMode = TIM_SLAVEMODE_EXTERNAL1; sSlaveConfig.InputTrigger = TIM_TS_ETRF;

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

Recently, The CubeMX cannot open IOC files through the file menu, and cannot save IOC files when creating a new project. But I can open the project normally by double clicking an existing IOC file.Working environment: Win11+CubeMX6.15I have tried reinstalling CubeMX, lowering CubeMX version to 6.13, and so on, but they all have the same problem. 

Hi,    Why NUCLEO-H753ZI ADC channel 12 is missing in CubeMX ?     ADC channel 12 is in NUCLEO-H753ZI board CN9-9 connector.     A few other ADC channels are also missing in CubeMX.    Thanks, Rong

 dear ST and/or Users,we’re using a STM32H743I and are planning to implement eeprom emulation as per an ST sample code.The algorithm employed in this code uses Flash Bank 2, Sectors 6 and 7 - we would store a few calibration values in these sectors of non-volatile memory.  The remainder of Flash memory is then available for our program memory.Once the product reaches customers there is always a possibility that the program may need upgrading.  How would we use the STM32CubeProgrammer to update program memory without touching the two sectors that are being used to store calibration data which must remain unchanged, please ?Is it sufficient just to tick <Skip flash erase before programming> and NOT to tick <Full chip erase>, and then commence programming ?  These two options are shown in the “Erasing & Programming” page of the STM32CubeProgrammer.Thanking you in advance for your assistance.

After migrating the project for STM32F765VGTx in cubeMX from version 6.14.1 to version 6.15.0, the parameter "WITH_RTOS (Use FREERTOS ** CubeMX specific **)" in lwip -> tab "General settings -> RTOS dependency" is inactive, and takes the value disabled,while the use of FREERTOS is set to CMSIS_V2.Also I can't change "NO_SYS (OS awareness)" from "OS not used" in the tab "Key parameters -> Infrastructure - OS awareness parameter".When creating a new configuration, the problem is not solved.I add two configurations, one before migration, the other after.

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. The result i

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? 

I'm starting a project and need to use the STM32F412G-DISCO board for initial development.I already had one board purchased in 2020.I downloaded the latest STM32CubeMX and created a new project based on this board with all default options. STM32CubeMX includes, by default, SDcard support.When I flash the generated code, the MCU enters the Error_Handler during initialization, right in the SD_WideBus_Enable(SD_HandleTypeDef *hsd) call.I commented out the SD initialization in main.c and then the program runs ok.So, for some reason the SDcard initialization crashes the code.Looking for a possible cause for this problem I downloaded also the latest demo binary (ver. 1.3.0) from ST's website. Flashed it and... doesn't run, the board does nothing an, I suspect, the code is also crashing during initialization. Looking on the web, I found a couple post from people indicating that the pinout generated by newer versions of STM32CubeMX for this board by default is incorrect. So I lo

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.

Hello,I am working on an HMI product with STM32H7B0RBTx LQFP64 and want to use the RGB888. As per Datasheet, it seems possible:But when I start a project on CubeIDE, it only provides only RGB565/666. My question is:- Is this a limitation in the CubeMX and I can use RGB888 if I do it manually?- If it's not the case, please to let me know and correct it on the datasheet.Thanks,Ayoub

In the SPI options for STM32H7S3, the "Prescaler (for Baud Rate)" drop-down box has various values from 2 to 256, but the option to bypass the prescaler is missing.To be clear, I'm referring to the BPASS bit in register SPI_CFG1:To get around this, I add a few lines to the generated code: hspi1.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_BYPASS; if (HAL_SPI_Init(&hspi1) != HAL_OK) { Error_Handler(); }This works. But to avoid people having to do this in the future, could you add the bypass option to Cube instead?Thank you.

Software: CUBEIDE:1.18.0Firmware: STM32Cube_FW_H7_V1.12.1 Board: NUCLEO-H745ZI-Q The problem is as follows: when using this chip for dual core communication, reproducing according to the example given by ST, communication cannot be carried out no matter what. Through debugging, it was found that the problem lies in the OPENAMP_create_endpoint() function in the M4 core. The return value is -2005, but as a beginner, I am unable to pinpoint where the problem lies. I will attach my project at the end of the article. My original goal was for the M7 core to send data to the M4 core, which would then print the data while the M7 core's LED would flash. I have reviewed the corresponding routines in ST's AN5617 and firmware, and watched the corresponding videos, but still cannot solve the problem. I request your help
