Hi,     My STLINK for debug in Nucleo-H753ZI board stopped working.      It was working when entering the debug mode.      Now, it stopped working.- I got the error message -  1. "Error in initializing ST link device." 2. "Failed to execute M1 command....".    Thank you very much for your help, Rong          

Hi. I was using STM32CubeIDE 1.14.0 until yesterday.Build Analyzer worked fine in 1.14.0, but after updating to 1.15.0 using the update feature provided by CubeIDE, nothing is displayed in Build Analyzer. The build was successful and the <project>.map file was created, but the Build Analyzer information was not displayed, and I uninstalled and reinstalled CubeIDE, but it was the same.   

hello, I have started a project where I have to use SPI, USART, and some modified labeled GPIOs in the nucleo-H755ZI-Q (nucleo-144). Whenever I configure the GPIOs in my ioc file and click generate code. My Cube IDE is not auto-generating code for my modified GPIOs. i have checked again and again there is no option for selecting the core for GPIO_output. Has anyone ever encountered such a problem? For reference, I will attach my project file.  1. I have used Cube MX for generating the IOC file and then imported it into Cube IDE. It did not work.2. I have repair reinstalled my Cube IDE. No use, did not work. 3. I have downloaded and installed the upgraded version 1.18.1. still facing the problem.4. I have downloaded and installed the 1.16.0 version. still facing the same problem. 

There is no code generated for the led_rgb_toggle() call here:led_rgb_toggle() is an inline function:static inline void led_rgb_toggle( GPIO_PinState r_state, GPIO_PinState g_state, GPIO_PinState b_state ) { #if defined PROJECT_WITH_RGB_LEDS if( r_state ) HAL_GPIO_TogglePin( LED_R_GPIO_Port, LED_R_Pin ); if( g_state ) HAL_GPIO_TogglePin( LED_G_GPIO_Port, LED_G_Pin ); if( b_state ) HAL_GPIO_TogglePin( LED_B_GPIO_Port, LED_B_Pin ); #endif } PROJECT_WITH_RGB_LEDS is defined in the Project defines (name has been changed for confidentiality): It is working in other places.Why would there be no code generated here? This is CubeIDE v1.13.0 on Win 11There are no build errors or warnings.

I would like to filter available products by the following specific peripherals, but those types of filters do not seem to be available.PSSIDMAMUXMDMALPDMAGPDMAHPDMASDRAM support andMinimum #of pins sized package to actually support 1 or 2+ SDRAM chips at 16, 24, or 32 bit Did I miss something or are there maybe future plans to support that kind of filtering ?Are there alternative papers/docs listing the products (and which are kept up to date) ? 

Sometimes CubeMX do not generate code correctly, not always, but sometimes in initialization codes generated by CubeMX is missing declarations in peripheral settings for DMA with error "undeclared",  currently I got this problem after clocks configurations and code regeneration, there is missing TRANSFERALLOCATEDPORTSRC_GPDMACH1, TRANSFERALLOCATEDPORTSRC_GPDMACH2, TRANSFERALLOCATEDPORTSRC_GPDMACH3.... declarations:I have to set new unused channel in DMA config again, disable old and regenerate code to solve this problem !

Hello, I just updated from 1.12.0 to 1.13.0 and now when i save changes it asks me to sign in to mySt to download a software package. When i try to login to my ST i get this error: I am on my work network, not sure if that matters. My internet is working fine with everything else but the STMCubeIDEThank you,

I am using STM32F030C6T6 mcu and i am trying to put its 3 ADC channels on DMA circular mode, but ADC is not initializing in circular mode, pls check below code:uint16_t adc_buff[3] = {0}; HAL_ADCEx_Calibration_Start(&hadc); HAL_ADC_Start_DMA(&hadc, (uint32_t *)adc_buff, 3); static void MX_ADC_Init(void) { /* USER CODE BEGIN ADC_Init 0 */ /* USER CODE END ADC_Init 0 */ ADC_ChannelConfTypeDef sConfig = {0}; /* USER CODE BEGIN ADC_Init 1 */ /* USER CODE END ADC_Init 1 */ /** Configure the global features of the ADC (Clock, Resolution, Data Alignment and number of conversion) */ hadc.Instance = ADC1; hadc.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV1; hadc.Init.Resolution = ADC_RESOLUTION_12B; hadc.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc.Init.ScanConvMode = ADC_SCAN_DIRECTION_FORWARD; hadc.Init.EOCSelection = ADC_EOC_SEQ_CONV; hadc.Init.LowPowerAutoWait = DISABLE; hadc.Init.LowPowerAutoPowerOff = DISABLE; hadc.Init.ContinuousConvMode = ENABLE; hadc.Init.DiscontinuousConvMode =

I trying to debug to find what line in initialization function throw hard fault and cant understand why "jump over" dont work like expected, in some moments jumps not to next row in code, then goes back...After running normally must start at  SCB_EnableICache() line, but starts from main:Then step by step must goes in that way:But goes/jumps in this way:SCB_EnableICache();SCB_EnableDCache();MPU_Config();MX_GPIO_Init();SystemClock_Config();And throws hard fault error inside SystemClock_Config function at HAL_Delay(HSE.....I am not sure if hard fault is fired because there is misconfig in cubeMX (I think not), or there because in some way is missed HAL_Init and other initializations, code cleaning, restarting and other things does not change anything, I have posted about some other problems earlier with initializations and bugs, but now I stuck there and cant work with code at all, cubeMX, cudeIDE, mcu package and everything else is updated to last available versions !Main

There is the problem for STM32Cube FW_C0, i need to use v1.1.0 because in v1.2.0 its no able to set PA9/PA10 as uart on my chip but i cant to select v1.1.0 which installed on my PC. 

Hello, I am using the STM32 nucleo-h753zi board. Is it possible to use zephyr within STM32CubeIDE exclusively? I have tried;https://docs.zephyrproject.org/latest/develop/tools/stm32cubeide.html  and it hasn't worked yet.

HI,Just notifying this as a solution if someone else has the same problem.By no apparent reason, the columns of IAC page on .ioc configuration editor running on CubeIDE become uselessly narrow (see image below). Restart the IDE did not help. Other pages show normally. In CubeMX this does not happen.The solution is to move the separator bar between the project hierarchy panel and editor panel to left. Apparently the IAC page does not handle the width scaling correctly (other pages on that tab do that nicely).Cheers, heke 

Hi , allI am currently working on a project using the STSPIN32G4 together with the STM32 Motor Control SDK (MCSDK). I would like to add the internal Temperature Sensor to monitor the MCU temperature.In STM32CubeMX, I have already enabled both the Temperature Sensor and VREFINT channels on ADC1, and generated the initialization code. Then, I configured the Temperature Sensor and VREFINT using the RDivider_Handle_t structure, and used the related APIs to read the ADC values.However, no matter whether I read the Temperature Sensor or VREFINT, the ADC values are always very close to zero, as if the sampling is not working correctly or is misconfigured.My questions are:Within the MCSDK framework, is it possible to directly use RDivider_Handle_t to read the Temperature Sensor and VREFINT channels?If not, what is the correct way to configure and acquire the ADC raw values for these internal channels?Are there any additional calibrations or specific initialization procedures required? Thank yo

I am using Stm32 N657X0-Q board with a stm32cubeide version 1.18, started with creating new project-> gave name-> selected appli in project structure-> selected gpio pin PA5 as output -> and generated code but in code generation under core-> there is no related files inside src and inc folders. can you help me in how to use this board. 

I cant get faster SPI performance, in every SPI DMA request mcu receiving 164 bytes of data, the maximum request rate what I got is about 1KHz, total number of bytes is only ~ 164 * 1000 = 164KB, I need to reach 8KHz rate, MCU and other clocks is set to almost maximum values, on STM32H7 MCU with many other tasks I reached without any problems 12KHz rate, with N6 I cant get event near of required transfer speed in any configurations, If I rising request rate I getting SPI busy error, where can be the problem ? What peripherals or other settings is responsible for SPI transfer and interfere there ? I can attach .IOC file or more info.In my setup SPI requests is controlled by HAL_TIM_PeriodElapsedCallback(), sometimes I need to stop requests in case when synchronization is lost, timer fires function for next SPI DMA transfer and in case of error (in my case I getting SPI busy error) the timer for request is stopped, timer fires simple function:void nextPacket(){    if (HAL_

Dear STMicroelectronics Support Team,I am experiencing a persistent and frustrating issue with STM32CubeProgrammer on my Windows 10 system, where the top menu bar (File, Edit, Options, Help, etc.) is completely missing when the application launches. The main window appears, but without the menu.This issue persists across different versions of STM32CubeProgrammer.Here are the detailed symptoms and troubleshooting steps I have already performed:1. Problem Description:When launching STM32CubeProgrammer (both v2.19.0 and v2.18.0), the main application window appears, but the entire top menu bar (File, Edit, Options, Help, etc.) is absent.The application does not crash immediately; it simply displays without the menu, making it unusable. (Initially, it would flash and disappear, but after a clean reinstall, it now stays open without the menu.)2. Key Observation (Important Clue):STM32 Trusted Package Creator, another STMicroelectronics GUI tool, works perfectly fine on the same system, inclu

I have a request.The complexity of the peripheral features and the peripheral registers with the inter dependent settings makes it difficult to get everything right the first time or even after multiple tries.  This involves a code generation, code compile and download just to try one different setting. This is not very efficient nor is it a good use of available resources. Would it be possible to use the STM32MX GUI as a direct controller to modify peripheral settings in real time as the micro is running? I'm working with a comparator, a timer, DMA, and DFSDM. When I try to interconnect them so the run without code, I have very little visibility to what is going on and trying out many configurations and combinations can be very time consuming.There is a lot of power in the peripherals but it is not easy to tinker and try things out. I have used the debug IDE to modify peripheral registers in real time, but that has its hazards.Firstly, there is no feature driv

Hello I have a question.The '0' s instead of 0xFFFFFFFF in the memory is something that really occurs on the flash memory or it is a value that appear because the stm32cubeide is not able to read all the position of the memory, or in other words, the IDE is unable to confirm that the memory is empty.  Thanks a lot.  

I have just updated the IDE from 1.12.1 and updated my project as requested but I have encountered an issue when compiling.I get 3 errors on previously compiling  source code. as followsCan you help with what might be the problem?PhilW

I am attempting to debug code on a Necleo-U385RG-Q board using STM32CubeIDE V1.18.1 under Windows 11. I beleive that under \plugins\com.st.stm32cube.ide.mcu.externaltools.openocd.win32_2.4.100.202501161620\tools there should be a scripts directory that contains cfg files for ST-Link V3 and my board. However, there is no scripts directory anywhere in the installation. Nor is there for my STM32Cube Programmer installation. When setting up the debug configurations I am able to select ST-Link GDB Server as a debug probe. This does get the board's serial number. However, because of the missing files I expect to see in the scripts directory, I get nothing when selecting ST-Link OpenOCD. I believe I should put the path to the cfg files under OpenOCD options.
