STM32 MCUs Software development tools

I have setup STM32 VScode extension in my PC, which is awesome. But I found I can not use a Jlink or daplink to flash or debug my board, only STlink is supported. How can I debug with other debuggers in VScode?  Any help will be appreciated.

Hi,I encountered the following problem on two different computers with different versions of STM32CubeIDE. I select File->New->STM32 Project, then i select MCU or Board and click to Finish. Then pops up window called "STM32 Project" to fill up project name. Usualy there is "next" button to select another features, like which CubeFW version to use etc. But now, the "next" button is greyed out. Probably due field called "Target Project type" with greyed out option "STM32 Cube". When i hit "finish" button, IDE creates empty project without ioc file - in other words it does not open CubeMX to configure project.I am not aware of interfering with the IDE in any way (plus I observed it on two independent PCs). I am including screenshots.Thanks,MichalVersion of CubeMXCubeFW is actualEmpty projectmissing option to use Cube

Hi, I'm creating a new project in STM32CubeIDE 1.19.0, but the .ioc file is not being generated. Online sources suggest it might be due to the FPU not being initialized. Only the files shown in the second picture are being created.

Hello, From the UM2408 document, the HSE is connected to ST-Link MCO output which is supposed to be 8MHz.When you select Nucleo-H755ZI-Q board, the HSE input is locked to 25MHz. Is it a CubeMX bug or does the MCO clock really 25MHz ? 

Hii working on stm32u083rctx with U0 fw package v1.3.0 and CubeMX 6.15. On CubeMX i initialized lpuart3 in half-duplex mode on PC4 pin. I notice that PC4 is only possible to set as open-drain. I want to select PC4 as push-pull. In function:void HAL_UART_MspInit(UART_HandleTypeDef* uartHandle)if i change PC4 init line form:GPIO_InitStruct.Mode = GPIO_MODE_AF_OD; to:GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;my code is working. I don't known if it is correct configure push-pull when lpuart3 is in half-duplex mode. So i ask if it's safe to do that. Thank you.Best regards.Enrico

"Hello, I am using a NUCLEO-H7A3ZI-Q board. I flashed two programs successfully, but on the third attempt, it stopped flashing because I accidentally forgot to enable Serial Wire Debug. Now, when I connect a charging cable, it shows 'No target found,' and when I connect a data cable, it shows 'No ST-LINK detected.' Please help.

I have a problem with CubeIde (version independent tried on both 1.13 and 1.16)the problem is that in live expression I am using a struct to combine each task in single struct for debugging purposethe values of the variables all shifted down example:var1: 0var2: value of var1var3: value of var2char arr[100]: [value of var3                        value of arr[0]etc]I am using threadx, the problem doesnot exist when working on UBUNTU while in windows is happening all time.the other thread values are correct, it happen only on the second thread. /* Includes ------------------------------------------------------------------*/ #include "app_threadx.h" /* Private includes ----------------------------------------------------------*/ /* USER CODE BEGIN Includes */ #include "main.h" #ifdef ExampleProtocole #include "ExampleCommunicationTask.h" #endif /* USER CODE END Includes */ /* Private typedef --------------------------

Hi everyone,I'm running into a consistent crash with STM32CubeIDE 1.18.1/1.19 right after selecting or creating a workspace,  after upgrading from version 1.13.1. I working on a corporate-managed Windows PC with SentinelOne installed.I attached the log file below. Based on what I see, I think it could be a problem with a certificate or proxy settings, maybe some leftovers from the old 1.13 version. We had some proxy changes internally, while I must say... I am the only one with these problem here.What I’ve tried:Fresh install of CubeIDE (even removed CubeMX)Creating new workspaces with different names and pathsForcing trust store type via .ini and environment variableDisabling Eclipse proxy settings (-Dorg.eclipse.core.net.enableProxies=false)No luck so far. Has anyone run into this before with Eclipse-based IDEs or corporate security software?Any help is appreciated!

I am trying to get the SMT32 VS Code extension working and have installed the dependencies on my Mac. However, the extension doesn't seem to find Cube CLT.I ran into a couple issues during the install. First, it said that st-stm32cubeclt_1.17.0_23554_20241124_1810-macosx_x86_64.pkg” cannot be opened because it is from an unidentified developer.I had to go into security and privacy settings and allow the install. After that, the installer was successful, but I can't seem to find where it installs. Anyone have an idea?

The original Thread "CubeIDE forcing you to login to ST ...", opened by @JDoe.2 in August 2023 with 37 Kudos for JDoegot shut down (flagged as read-only) today with a last statement by @Amel NASRI which is marked as "Solution". Congratulations ST, now I am really upset. Now I know you read the community postings, you just prefer to ignore them if they are annoying. Flagging a thread as read only and posting an "alibi" technical solution where the thread clearly shows that thread was not about technical issues in common, but your customers do not want to be forced to log in to use your product is an affront against all those people who spoke out against those new policies. Please take this posting as my formal protest against your action.Edit: shortened Title to reflect the note from Amel  

Hello, I am trying to build a api in stm32 cube ide with base mcu as nucleo board.i am planning to build a api with input parameters GPIO_PIN,IRQ_HANDLER_FUN.UserAPI_exticf(GPIO_PIN,IRQ_HANDLER_FUNC){}I don't want ot configure gpio as exti in .ioc file and use it main cI want everythibg to be done in UserAPI_exticfg. If you have such reference code or libraries please share it. 

I downloaded STM32CubeIDE to my computer. However, when I tried to launch it after the installation, I got an error saying "An error occurred while starting the installer." What could be the reason for this issue?

hi, cube ide updated with latest version  1.19.0 have bug as below picture . By default quad spi is disabled and i could able to select quad spi in older version cube mx by using old project and continue with old cube mx version not migrate .  

Hello I manage to install cube ide on Ubuntu 24.04 custom docker.The internet connection works as i properly configured the proxy and install my certificates on the system, and on the java side (jre/bin/keytool) of eclipse based Cube ide.The check connection works in 'windows > preferences > STM32Cube > Firmware updater' menu (see attached image) and I am able to download and install some of the updates via 'help > check for update menu'The compilation of my project works and also able to debug and program via st link from the docker.Nevertheles I still encounter a problem when i tried to connect to my st account, via 'Help > STM32Cube updates > Connection to St' i have a first page where i can click on 'Enter myST account information', then it the open a second page based on a web browser (see attahed image) where it states that This site can’t be reached The webpage at https://sso.st.com/as/authorization.oauth2?client_id=oidc_prod_stm32cube-ua-cubemx1&

Hi @stm32 I have a STM32U5G9 chip connected to a NOR_FLASH Memory MX25UM51245G using OctoSPI. I created an External Loader for the setup, but unable to read/write using the stm32 programmer. The custom driver I developed for the particular flash is proved to work with the same hardware setup, so i can confirm that the bridging between the working driver and the STM2Programmer is somewhat missing. Steps I Followed to create the Loader are:1) Created a CubeMx project for stm32U5 with OctoSPI enabled in my case.2) Manually copied the loader files from the link https://github.com/STMicroelectronics/stm32-external-loader/tree/contrib/Loader_Files and also integrated my custom driver for the particular NOR_FLASH. The driver is tested and verified separately,So it works.3) In the build configurations, pasted the command cmd.exe /C copy /Y "${BuildArtifactFileBaseName}.elf" "..\${BuildArtifactFileBaseName}.stldr" to create stldr. After further debug

Using latest STM32CubeIDE version 1.18.1 and STM32Cube_FW_F4_V1.28.2 available for use.Note that this new firmware has board examples in STM32CubeIDE project format and no longer in SystemWorkbench.Using STM32CubeIDE to Import STMCube example, after selecting the board, e.g., STM32F4469I-DISCO, then an example, e.g., GPIO_EXTI, you get a STM32 project, but it doesnt compile with the IDE. It doesnt seem to have any .ioc file, etc., even though the target board was specified from the beginning. Pic 2 selects board and example, then last pic shows the project. But IDE isnt able to compile this project (hammer is gray, etc.).Why? How to create the example so that it will compile for selected target board? Is the new FW useless, eventhough it shows STM32CubeIDE projects for the examples, applications, etc? 

Hello. When I click on check for update in the help tab in stm32 cube ide, I get errors in the uploaded images.eroravailable software sites

Hello!We have recently updated our STM32CubeIDE to a newer version (1.19.0, from 1.18.0) and we have encountered an issue when using CubeMX. Whenever we launch the code generation some code sections in the file 'app_freertos.c' get duplicated. For example:/* Definitions for defaultTask */ osThreadId_t defaultTaskHandle; const osThreadAttr_t defaultTask_attributes = { .name = "defaultTask", .priority = (osPriority_t) osPriorityNormal, .stack_size = 1024 * 4 }; /* Definitions for i2c_Task */ osThreadId_t i2c_TaskHandle; const osThreadAttr_t i2c_Task_attributes = { .name = "i2c_Task", .priority = (osPriority_t) osPriorityAboveNormal, .stack_size = 512 * 4 };will become:/* Definitions for defaultTask */ osThreadId_t defaultTaskHandle; const osThreadAttr_t defaultTask_attributes = { .name = "defaultTask", .priority = (osPriority_t) osPriorityNormal, .stack_size = 1024 * 4 }; /* Definitions for i2c_Task */ osThreadId_t i2c_TaskHandle; const osThreadAttr_t i2c_Task_attributes = { .n

Hi, When I moved the default pin assignment to the alternative, in this it is PA15, as the below picture shows PA15 now sports a "pin" icon. What is the significance of this please? Edited by ST Moderator to add the right label.

Hello team, I am new to STM32CubeIDE. I have a NUCLEO-H743ZI2 board. When I try to open an example project, it shows the message: 'Target NUCLEO-H743ZI2 is obsolete according to marketing status,' and the .ioc file is not generating. I have already installed the latest version of the IDE. Could you please help me resolve this issue?

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.

Hi,i working on stm32u083rctx micro with package FW_U0_V1.3.0. I want to report that in CubeMX v6.15 i selected lpuart3 to with LSE oscillator. The execution of product code, when lpuart3 has been initialized goes to Error_Handler() function. In file usart.c into function HAL_UART_MspInit() miss the the line to populate struct PeriphClkInit.Lpuart3ClockSelection with correct clock source. So inside HAL_UART_MspInit(UART_HandleTypeDef* uartHandle) at the appropriate condition (uartHandle->Instance==LPUART3) before to call HAL_RCCEx_PeriphCLKConfig(&PeriphClkInit) i inserted:PeriphClkInit.Lpuart3ClockSelection = RCC_LPUART3CLKSOURCE_LSE;now is working. I ask to someone to double check this issue. Thank you.Best regards.Enrico.

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?
