STM32CubeIDE (MCUs)

Are there any plans to upgrade STM32CubeIDE to include support for C23?It would be nice to have as it brings things like constexpr in, which makes the use of constants much better as they are subject to compiler checking and can call (constexpr) functions.

Hello,I need guidance to create a very simple AI project using CubeIDE (CubeMX) and Neural-ART runtime. I can use all the example projects successfully but failed to create one from scratch till now. I faced no challenge earlier when using H7 for my AI projects.I am using STM32N6570-DK. I tried using different ways, but I either got strange compilation/linking errors or got stuck in the neverending "Generating code" screen.Anyway, my latest attempt is as follows:Create a new FSBL project by selecting my DKChose not to initialize default peripheralsSelected X-CUBE-AI 10.0 core and template application from the Middleware sectionSelected a MobileNetV2-based tflite model and Neural-ART runtime.Analyzed using "n6-allmems-O3" and generated code. Everything is OK so far.Tried to build and got errors and warnings.Errors and warnings:RIF-related error/warning in app_x-cube-ai.c.  ./X-CUBE-AI/App/app_x-cube-ai.c: In function 'MX_X_CUBE_AI_Init': ../X-CUBE-AI/App/app_x-cube-ai.c:100:5:

I am fairly new to programming. So I have STM32CUBEide at work and at home. If find it extrodnarilly difficult to work on something at the office and then take it home or in reverse. I have tried exporting, importing, importing from the file system and just copying files directly. Each time only after several hours I stumble upon getting the project working and I have to do it all over aging when I go back to the office.  And really irritating is that it looks like its going to work, when your importing an archive and just as you go to select the location. The darn window is gray out.  And when the IDE finally does work it is not obvious why. Despirite for help!!!

I have internet access at my office only through a virtual machine.I'm facing an issue with updating Cube-IDE. Currently, I'm using version 1.11.0 and I want to manually update it to version 1.13.1.I've downloaded the executable file for version 1.13.1 from the website, but my previous code doesn't seem to open in this updated version.Could you please guide me on how to connect my existing workspace (workspace_1.11.0) with the new version? Alternatively, if there's an alternative method for manually updating CubeIDE, I'd appreciate the advice.    

I have developed software in STM32CubeIDE using the NUCLEO-L433RC-P dev board.This board uses the STM32L433RCT6P (which has an external SMPS for VDD12 pins) but the PCB I am designing uses the STM32L433RCT6 (without external SMPS).When my PCB arrives, I will need to retarget the MCU in STM32CubeIDE from the STM32L433RCT6P to the STM32L433RCT6, but I cannot see how to do this.I tried to create a new project (including the .ioc file) using STM32CubeMX and copy files accross, but got into a mess and could not get it to work.Ideally I would like to be able to easily switch between both MCUs, so that I can continue to develop the software on the NUCLEO-L433RC-P until my PCB arrives.How do I retarget my software to the STM32L433RCT6 ?

Hi everyone,I am using an STM32H750 microcontroller and programming it through CubeIDE.After updating STM32CubeIDE to the latest version (1.18.0), ADC3 stopped working. For some reason that I couldn't identify, the EOS bit in the ADC_ISR register is not being set after the conversion.I have already downloaded the previous version (1.17.0), and the firmware still works on it.P.S.: I am using ADC through BDMA.Below is the function that stopped working and the ADC3 configuration: void adc_sample(void){LL_ADC_REG_StartConversion(hadc1.Instance);LL_ADC_REG_StartConversion(hadc3.Instance); while(!(LL_ADC_IsActiveFlag_EOS(hadc1.Instance)));while(!(LL_ADC_IsActiveFlag_EOS(hadc3.Instance))); LL_ADC_ClearFlag_EOS(hadc1.Instance);LL_ADC_ClearFlag_EOS(hadc3.Instance);} /** Common config*/hadc3.Instance = ADC3;hadc3.Init.Resolution = ADC_RESOLUTION_12B;hadc3.Init.ScanConvMode = ADC_SCAN_ENABLE;hadc3.Init.EOCSelection = ADC_EOC_SINGLE_CONV;hadc3.Init.LowPowerAutoWait = DISABLE;ha

Hi All, I am using STM32H747IDISCO kit. I make a new project on STM32CubeIDE(Vewsion 1.18.1), following these steps below. 1.Start STM32CubeIDE(Vewsion 1.18.1), and click [Start new STM32 Project] button on STM32CubeIDE Home. 2.Input "STM32H747I-DISCO" in Commercial Part Number Box on Boad Selector tab. 3.Click Boads list 1 item displayed on right side, and click [Next] button. 4.Input "TestPrj" in Project Name Box in STM32 Project daialog, and click finish button. After a while, TestPrj.ioc is opened, then click Project -> Generate code.  C/C++ perspective is opened. I add some processes in CM4 main function that turn on LED1 like the following. /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init(); /* added proccess start */ { /* Configure the GPIO_LED pin */ GPIO_InitTypeDef GPIO_InitStruct; __HAL_RCC_GPIOI_CLK_ENABLE(); GPIO_InitStruct.Pin = GPIO_PIN_12; GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP; GPIO_InitStruct.Pull = GP

We've got a STM32H747IGT6 which is the two-core version (one M4, one M7).  I've got GDB servers running on ports 61238 (CM4) and 61234 (CM7) and then running two instances of GDB (one for each server).  GDB says it's happily connected, and I can load code and inspect memory on both cores but when I set a breakpoint on the M4, gdb says "Note: automatically using hardware breakpoints for read-only addresses." and the breakpoint never fires.  On the M7, gdb doesn't give that same warning and breakpoints actually work.Is this a known limitation of the M4, or is it something I've got set up wrong? 

I added a folder called Docs to my project, then created release notes using Word and dropped in the newly created Docs folder. When I try to build, I get a message box:How do I fix this?

Hi,I am trying to export (and then import) a project on STMIDE from one computer to another but it's been not so straight forward. Hoping somebody can point me to the right direction or a step by step on how this is properly done. For context, when I export the project and try to import into another computer - the project is missing nearly all of the files except for a few..?  Thanks

I was using STM Cube IDE version 1.17.0, and I am not getting the option to choose the Stm32Cube in Target Project type by default it is selecting the option of empty. I have been using the same version for few months and I have never faced this issue.. Could you find a solution for this.

HiLast week I installed the latest version of stm32CubeIDE on my Fedora 42 system using the generic linux installer from the ST web site. The installation went smoothly and I was able to run the program and even generate a simple project.When I went back 2 days later to continue, each time i ran CubeIDE the system starts and displays the standard "workspace" window. Upon hitting enter a small empty windows comes up and the system hangs there. The app does not appear to close since if I try to start again I get the message that the app is already running.Any ideas please? 

Hello,A few days ago I installed stm32cubeide on linux mint and successfully created a test project with STM32Cube.Today, if I try to create one, I can only Targeted Project Type : Empty, as STM32Cube is greyed.Why?

When creating a project with the new STM32CubeIDE 1.19.0, I get the following error: Does anyone knows how to fix this?

Whenever i rename a project. launch file is created and a number of. launch files are generated for each project name, is it possible that automatically that the old launch files are deleted, i can delete manually but just checking if it can be deleted automatically as soon i rename the project.

ChatGPT says my STM32 Repository Path is wrong but I can't find it in IDE. I don't understand how all these paths work and package manager + "Device Configuration Tool" (New name for MX I guess.) Which AZRTOS do I use? I have an H5. And that is not one of the AZRTOS options.I had this all working in 1.18.1 - I'm not sure what's getting shared between instances. So now I'm rebuilding in 1.19.0.

Hi there!Both STM32CubeIDE and the ST MCUFinder tool incorrectly mark the STM32H503 as having a CORDIC and FMAC when they don't.Could this please be fixed as it's very confusing.Thank you!

Hi Community,I'm new to STM32CubeIDE and currently working with the STM32H723Zx in the LQFP144 package. While configuring the SAI1 peripheral, I encountered something that seems counterintuitive.When I set the output mode to Mono, the "Number of Channels" option only allows 2 channels to be selected. However, when I switch the output mode to Stereo, I can select up to 16 channels.This behavior seems reversed to me—shouldn't mono mode allow more flexible channel selection, or at least fewer limitations than stereo?I've attached a screenshot below for reference.Any insights or explanations would be appreciated!Thanks in advance.  

Hello, My project is working with stm3h743 HAL version 1.0.0 (the first one ever created).I am trying to update to the latest HAL version which auto generate by Cubeide 1.18.1 (Fw package 1.12.2).  I am using spi1/2/4/5 full duplex mode but currently I have problem with spi 5 through _IT mode (no DMA).The problem occurs only when I use HAL_SPI_Receive_IT for reading. In the old HAL I use   this->handle.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_2 and i am reading successfully through spi5.However, if I take the new hal and don't change anything else i get overrun error. (The same slave Hw of course).  One solution (but not a good one) I found is to use SPI_BAUDRATEPRESCALER_128 but it hurts performance and seem not to be stable.What could be the problem?  One more thing, I notice that in the old HAL if we are the master and use 2 lines, we call HAL_SPI_transmitReceive_IT (inside HAL_SPI_Receive_IT).In the new HAL its different- w

Hi everyone, I created an HID bootloader for the STM32G4xxx, it works and now I am trying to optimize the size. After compiling I can read this on the Build Analyzer a flash memory usage of 17.85 kB. After compiling I get this: When I flash this compiled code and read the flash memory I canclearly see that the memory usage is around 38 kB.  I also used the STM32CubeProgrammer to look at the actual memory (I didn't manage to use this function directly on STM32CubeIDE) and I can see that more than 38 kB are used in the memoryCan somebody explain why? Am I missing something about the Build Analyzer function?  

Hello everybody,I have this project for the STM32F103C8 where the build analyzer of STM32CubeIDE says that only ~57% of flash is used:but while I'm flashing, it shows that the erased sectors are 0 to 56 (out of 63):and also using the STM32Programmer I see that the empty region starts at 0x800E048Now 56/63 ≈ 0xE048/0xFFFF ≈ 87% which is 30% higher than the stated 57% of build analyzer. This is kind of a bummer because now I will have to upgrade MCU since some other features must still be added to the project.How is it possible such a difference?

Hello,I am currently working on a config file for STM32H723ZGTx (LQFP144). I am setting up ADC1 and want to select "Conversion Data Management Mode" to be DMA one shot instead of regular conversion to DR register. However, I cannot seem to select this option, is there other settings blocking it? or am I missing something else ? I am really new at this cubeIDE :))Thanks for your time,Kewin  

The last couple of months I have been developing on an STM32H757I-EVAL board. Programming and debugging (multi-core) works reasonably well; although sometimes I need to re-power the board.During the last weeks, we transitioned from the EVAL board to the actual PCB design. Since then I have a lot of issues with debugging of the board.I use the ST-LINKV2 debugger in combination with STM32CubeIDE 1.18.0.Most of the times, the ST-LINK GDB server refuses to connect with the following error:Target connection mode: Under resetTarget connection failedTarget no device foundError in initializing ST-LINK device.Reason: No device found on target.Playing around with the setting shows that the ST-LINK GDB server does not connect when having the '--halt' option specified (to halt both cores). When I omit this flag, the GDB server is able to connect to the target.I need to re-power the board to get it working again (for a couple of tries, after that it stops again)Are there any known issues, or do you

Hi All,I am using STM32H747IDISCO kit.I load example project HSEM_COreSync into STM32CubeIDE(version 1.18.1) , and set a breakpoint at"BSP_LED_On(LED3);" line in main function on Cortex®-M4 side. And I start debug, but break doesn't occur.I recognize LED3 is turned ON after LED1 turned OFF. So "BSP_LED_On(LED3);" line should be proccessed, but break doesn't occur.I program the board following the guide.(https://www.st.com/resource/en/application_note/dm00629855-getting-started-with-projects-based-on-dualcore-stm32h7-microcontrollers-in-stm32cubeide-stmicroelectronics.pdf)Could you tell me how to break at  Cortex®-M4 address on STM32H7 dual core.Thanks in advance.

TL;DR - My setup works when I use a Windows laptop, but fails when I use a MacBook Pro (M3 Max).  I am looking for help on using my MacBook Pro (M3 Max) to program my Nucleo board.This is my first time trying to program / debug such a board.  I wrote a very simple C program to turn on the green LED (LD2) on my board:  https://github.com/rajesh-gopalan/stm32-nucleo-f446re/blob/main/0_led_toggle_addr.cMy focus is on the following basic hardware <> software setup (not the actual program content):Host Device  - 16-inch MacBook Pro 2023, with M3 Max processorBoard             - STM32 NUCLEO-F446REIDE                 - STM32CubeIDE                         Version: 1.17.0                         Build: 23558_20241125_2245 (UTC)Connectivity   -&nb
