Hello, I am trying to use the STM32CUBE RTOS STATE panel within VSCode as opposed to setting a watch variable for xQueueRegistry, but the state panel does not match what is shown in the queue registry. Only the first queue is shown. Also, I am curious how to get Semaphores to show up in the semaphores portion of the tree in the state panel. The semaphores I am using are binary semaphores which under the hood are just generic queues.  

Hello,I'm not sure where to begin with this issue. When I enable the RTOS Proxy as shown below in the debug launch configuration. And I flash and debug, I get the following error/crash. And I also have to unplug and replug the stlink v2 from the computer for it to be recognized again. This behavior is consistent except when I change the code structure in some small way like commenting out a few lines of code. Changing the code in some small way appears to make it work consistently again?

Hello.It's not possible to find a controller with a specific number of CAN buses using MCUFinder. MCUFinder counts each CAN bus twice: If it physically has 3 CAN buses, MCUFinder adds:    3 CAN buses + the same 3 CAN2.0 buses = 6 CAN buses.  This is great if it allows the controller's peripherals to be doubled so easily. Excellent. But it is very misleading because it raises false hope and displays completely unsuitable controllers.However, the program is useless when I'm searching for controllers with 4 or more CAN buses and I get a huge list of 70 possible controllers, all of which have at least 6 CAN buses, but none of them possess these qualities.  Can this bug be fixed?  

Hello Everyone!STM32CubeIDE version: 1.19.0STM32CubeProgrammer version: 2.18.0MCU: NUCLEO-STM32U575ZI-QI tried to use USBX DFU to update the firmware on the STM32U575ZI. The DFU mode was detected by STM32CubeProgrammer. However, when I clicked the connection button and disabled Read Out Protection, STM32CubeProgrammer was frozen as shown in the following picture Moreover, I tried to use DfuSe Demo to update the firmware. It erased the flash (I double‑checked this with STM32CubeProgrammer), but it could not write data to the MCU, as shown in the following picture. Could anyone provide us with some suggestions?We will be grateful for any help you can provide. reference:STM32Cube\Repository\STM32Cube_FW_U5_V1.8.0\Projects\STM32U5G9J-DK2\Applications\USBX\Ux_Device_DFU  

Dear STMicroelectronics Support Team,I am writing to report a persistent issue with STM32CubeIDE that is affecting multiple users in our company and blocking our development work.Issue Description:When we try to debug any STM32 project, the debugger launch process gets stuck at 51% with the message:Launching: Initializing debugger servicesThe issue occurs with different versions of STM32CubeIDE and with multiple target boards.Steps to Reproduce:Open STM32CubeIDE and build the project (build succeeds).Click Debug.Debugger launch stops at 51% and does not proceed further.Environment Details:STM32CubeIDE Versions Tested: 1.9.0 and 1.13.2 (same result)Operating System: [Windows 10 / Windows 11]Target Boards Tested:STM32F429I-DISC1STM32F407-DISCST-LINK Firmware: [if known, mention version]Actions Taken:Reinstalled STM32CubeIDE (both versions).Reinstalled ST-LINK USB drivers.Verified ST-LINK is detected correctly in Device Manager.Tried on multiple PCs within our company — all systems show

Created an account, activated it, signed in, and I'm stuck in a loop of clicking "Get latest" > Accept the license agreement > "Download latest" > Accept the same license agreement > "Download latest" > Accept the same license agreement > and so on. The download never starts. This happens when trying to download CubeMX as well. CubeIDE for vscode worked fine. This seems to be a reoccurring issue over the years. I'm using up to date chrome and have no extensions installed except workplace mandated Microsoft Purview which I cannot disable or interact with.

After installation of STM32CubeIDE in a new computer,  an error reminds when logging: This login session has expired! Please try to login again by going to myST-login,However even I  try to login by going to myST-login, still not succeed. More information for you reference :  computer Operation System is Win11,   IDE Version is 1.16.1I wonder how does this error come and how to deal with it to enable successful loginThank you very much 

Dear STMicroelectronics Team,My name is Yaswanth Kuna from India. I would like to report two issues related to code generation and X-CUBE-AI configuration in the latest versions of STM32CubeIDE, STM32CubeMX, and STM32 expansion packages.I am working with the STM32F407VG MCU and X-CUBE-AI 5.1.2.Issue 1: Missing “x-cube-ai” include folder after code generationEnvironment:STM32CubeMX 1.19.1Steps to reproduce:Create a new STM32 project.Clear all pinouts.Reconfigure all required peripherals manually.Enable X-CUBE-AI and configure it.Generate code.Problem:After code generation, the x-cube-ai include folder is not generated correctly.However, if I generate code using the default pinout, everything works correctly. This means the issue only occurs when pinouts are cleared and reconfigured manually.Issue 2: X-CUBE-AI configuration resets when reopening the IOC fileEnvironment:STM32CubeIDE 2.0.0 (with embedded CubeMX)X-CUBE-AI 5.1.2Steps to reproduce:Create a project in standalone STM32Cube

I have a vscode task that allows me to just flash the application using `cube` which has worked fine until I got the lastest extensions update where now running this task will give a "The "path" argument must be of type string.

Hi there! Thank you for reading this.Where has the support for exporting footprints/symbols to Altium Designer from STM32CubeMX gone?In the promotional video from https://www.st.com/en/development-tools/stm32cubemx.html it appears there is an option for doing this, but when I try it on a recent version of STM32CubeMX no option is available.What am I missing here? Check following screenshot of promotional video vs. STM32CubeMX side by side.STM32CubeMX version: 6.16.0

After upgrade from 6.15 to 6.16 on linux ubuntu 24.04 I got this blocking error if I load project file (created with cubemx 6.15):cannot invoke com.st.microxploer.mcu.IP.getInstanceName() because mpu is nullI tried both "migrate" and "continue" options but I got the same error. Attached the project file

Hello,I tested the new STM32CubeIDE 2.0 today and was initially confused that CubeMX opened when I double-clicked on the *.ioc file. However, this is listed as a new feature in the release notes.Unfortunately, this feature completely destroys my projects.When the code is generated, these settings in the CubeIDE project change:- Targeted Language changes from C++ to C- Linked folders are deleted- Configurations: DEBUG, SYSTEM added- Linker file settings from own configurations deletedDid I make a mistake in the settings? Why is the project changed so much?Best regards,Jens

Hi,Is it possible to add a MCU reset command to the debug toolbar? I.e. a button that does a pause then "monitor reset" type sequence? Of course I can do this manually in the debug console, but it'd be nice to have a button to do it, to complement the full restart button.Thanks!

MCU: STM32H563VITx Stm32CubeMX version: 6.14.0 HAL Driver version: 1.5.0 When I enable EDATA option bytes in CubeMX, it generates the following code: void MX_FLASH_Init(void) { /* USER CODE BEGIN FLASH_Init 0 */ /* USER CODE END FLASH_Init 0 */ FLASH_OBProgramInitTypeDef pOBInit = {0}; /* USER CODE BEGIN FLASH_Init 1 */ /* USER CODE END FLASH_Init 1 */ if (HAL_FLASH_Unlock() != HAL_OK) { Error_Handler(); } /* Option Bytes settings */ if (HAL_FLASH_OB_Unlock() != HAL_OK) { Error_Handler(); } pOBInit.OptionType = OPTIONBYTE_EDATA; pOBInit.Banks = FLASH_BANK_2; pOBInit.EDATASize = 2; if (HAL_FLASHEx_OBProgram(&pOBInit) != HAL_OK) { Error_Handler(); } if (HAL_FLASH_OB_Lock() != HAL_OK) { Error_Handler(); } if (HAL_FLASH_Lock() != HAL_OK) { Error_Handler(); } /* Launch Option Bytes Loading */ /*HAL_FLASH_OB_Launch(); */ /* USER CODE BEGIN FLASH_Init 2 */ /* USER CODE END FLASH_Init 2 */ }​ The function does not launch

Background: I have designed a new PCB, which includes a chip similar to one I've used on other PCBs, but with a different part number. The function names for this chip start with the part number.As mentioned, the new project uses a slightly different chip, with a different part number. To not start from scratch, I copied the chip-related files from a different project in the same workspace, and changed the function names. I used Refactor -> Rename to rename the functions, so it would do the source and header files in one go.But renaming didn't stop with the new project. It renamed identical function names in the older projects as well. All files where these functions were mentioned, were updated and saved. So now I have a file restoring task ahead of me. Thank Goodness for a cloud service with a file version history.Question:How do I avoid this in the future? I would very much like to limit renaming to a single project. But the only setting I have found regarding this is here:This i

As I understand it, this extension only works online? If there’s no internet, the extension stops working. Is there a solution for this or…

Hello everyone,I’m currently facing a blocking issue with SWD programming on an STM32U575VIT6Q placed on a custom PCB.Until today everything worked correctly: I use a CLI-based flashing procedure that programs a set of binary files (around a dozen) using commands like the following:%CLI_EXEC% -vb %VERBOSITY% -c port=swd dLPM -w "filename" %address% -vThe entire flashing sequence has always completed successfully, but during the last programming cycle I suddenly received the following error:Error: Cannot connect to access port 0! If you are trying to connect to a device with TrustZone enabled please try to connect with HotPlug mode. If you are trying to connect to H5 device and your target is already locked with password or certificate, please open your device using Debug Authentication.Since that moment, I have been completely unable to connect to the MCU with my ST-Link V2 in any mode.I tried:NormalUnder ResetHot PlugPower-downUnfortunately, all attempts fail with the same error.A few

Hello,Today I opened VS Code to work on my project and noticed the update was available. That's awesome, but typically we're forced to freeze our toolchain once we release the code to product, to avoid the risk that updates have unwanted side effects. Right now I've been evaluating whether we can use VS Code, or if we better stay with tried and true CubeIDE.It's fine for hobbyists to always update to the bleeding edge, but what about anyone using STM32 micro for application in automotive, medical, and defense application? It's a requirement to know that every possible change is tested before releasing code to the product, including toolchain and IDE updates. We can't know if there's a bug on day 0 of the release, of course!Can we understand if the ability to freeze version is on the development roadmap of the VS code plugin? If not ever, any safety critical application should probably avoid it, don't you think?Thanks.

The latest version of STM32CubeIDE for VSCode can have its performance affected by network conditions when working online. If the network is disconnected, the entire set of plugins may become unresponsive for a long time (ten or so minutes) before switching to offline mode. The whole plugin suite should be designed to primarily work offline, performing occasional network tasks in the background intermittently.  最新版的stm32cubeide for vscode ，在联网工作的时候，性能会被网络状态影响。如果发生了断网，则整个插件组会假死很久（十几分钟），才能切换到离线工作状态。整个插件组应该设计成离线工作为主，在背景状态、间歇性进行一些联网工作。

The CubeMX 6.16.0 is able to generate a CMake-project for an STM32H7 - great. A small conflict currently exists in the following two generated files [for a "basic" STM32H7 project]:- CM7/CMakeLists.txt:69# Add linked libraries target_link_libraries(${CMAKE_PROJECT_NAME} PRIVATE # Add user defined libraries )- CM7/mx-generated.cmake:81# Add libraries to the project target_link_libraries(${CMAKE_PROJECT_NAME} ${MX_LINK_LIBS}) The first specifies PRIVATEwhile the second does not - which is incompatible as per CMake. Can someone confirm this observation? Can this be made consistent in the future? If so, I would prefer the one with the scope keyword - but could also live without it here.

Hello,I'm slightly confused about the options in the STM32CUBE VSCode extension Project setup window.From the left dropdown i can select the Project, where i have options x, x_AppliSecure, x_AppliNonSecure and x_FSBL, for each of the left options, i can select Secure, Secure-only and Non-secure from the right dropdown for the Security model. I haven't found documentation which describes what do these options mean.For example, if i select x_AppliSecure from the left dropdown and Non-secure from the right drop down, which sounds like a conflict, what happens? In which scenario should i choose which of the 12 available Project-Security model combinations? Also, I assume that Secure means Secure + Non-secure, as Secure-only must mean secure only and Non-secure probably means Non-secure only?In the same window, multiple rows can be added to the list from the + button in the bottom right, what do the rows represent?Thanks! 

When enabling 2 ADCs ,  ADC1 and ADC2 of  STM32U5A5 ,both in Independent mode . The RCC enabling in MspInit called only for ADC1 and not for ADC2. What causes , that If one decide disable generataion of call to MX_ADC1_Init() in CubeMx , in order to call it somwhere else , but still enable generation to call to MX_ADC2_Init() in CubeMx , ADC2 won't work untill MX_ADC1_Init() is called.

Hi,I'm searching for a MCU with one or two advanced motor control timers to control 1 or 2 bldc motors.For this purpose I use the MCU selection tool from here: STM32 family of 32-bit microcontrollers (MCUs) - STMicroelectronicsWhen I use the filter for one or two advanced motor control timers the MCUs from the STM32G series are never displayed and I don't understand why? How should I search for all MCUs with motor control functionalities?Thanks for every hint!Best regards,Roger

Hi,still pretty, pretty new to STM32CubeIDE, I'm trying to understand how it works by doing little things. So right now I'm trying to combine both debugger with a terminal both running in STM32CubeIDE.To include terminal in STM32CubeIDE I have followed instruction given here:How to use the STM32CubeIDE terminal to send and receive data (Knowledge Base) So far, running a little test program, I was succesfull doing it at least for very first debug session (i.e. after power cycling the Nucleo-Board). I quit the debug session with the indicated button shown on attached figure belowHowever, when I start a debug session a second time, I get always(!) the same error message (see below)The only way I found so far is to make a hard power cycle to the Nucleo-Board to make it connected in the STM32CubeIDE again.Well, in STM32CubeIDE, because I also installed Tera Term and here everything is working fine. But actually I'm a fan of having thing in one application that can be in one.So my quest

Hello ST Community team.As a user who visits this Community several times a day, I’ve noticed the mixed feedback regarding the full separation between STM32CubeMX and STM32CubeIDE. Personally, I fully support this decision, and I believe it brings a positive direction for the tools. At the same time, I would like to suggest keeping the CubeMX plug-in available as an optional component in future versions of CubeIDE, so that users who prefer the integrated workflow can still enable it if they wish. This could help accommodate the different preferences within the community. Thank you for your continuous work.Best Regards.II
