STM32 MCUs Software development tools

Hello,I am converting from Arduino to STM 32 Cube IDE. Here I have a Problem with include paths:What I want:- Develop Libraries in a special folder- Add the libraries as a LINK to the Cube IDE- use #include command to include the library into the project What I have done:- I made a new Project "Blinky" in the cube IDE - done- I selected a nucleo board in the cube IDE - done- I programmed a hello world blinky using HAL without libraries - done.So the environment and the board is running.- right clicking on the project  I created a new source folder "MyLibs"By drag and drop I copied my library called "After" folder into the new MyLibs folder. Answered the message by "copy link only" into the new folder "MyLibs"The copied folder "After" contains an other folder "src" where the source files are located. Here a picture of the project: Now I go to properties and set the include path to the directory /MyLibs/After/src/: The second line indicates that I have included the di

I have five projects on the go, which compile and debug well on STM32CubeIDE 1.X.X (at least for 1.12.0+), but with warnings. I am now trying to shift to more recent versions of CubeIDE (2.X.X), but they behave as if ">Properties>C/C++Build>Settings>Tool Settings>MCU>MPU GCC Compiler>Warnings>Treat warnings as errors (-Werror)" is enabled, even when it is not.I believe that my settings in the more recent CubeIDE are identical to the older one, and I have tested this on two different computers with similar results. The error which is currently causing the compilation to halt is " ...error: implicit declaration of function 'xxxxx' [Wimplicit-function-declaration]", but if I resolve it, another item which should be a (legitimate) 'warning' will appear as an 'error'. I am using "ISO C11 (-std=c11)", and have the same issue if I attempt to use GNU11.Unfortunately, I cannot resolve all the warnings without creating other problems, so this issue is preventing me f

I'm trying to download Cube MX, Cube Programmer, and Cube IDE. I registered and activated the license, but it won't download. I've tried using different browsers (Chrome, Firefox, Edge) without extensions. I accept the License Agreement, but nothing happens. I tried it as a guest user, too, but it won't download. I really need the programs, what should I do?

We used to define STM32 pinout in STM32CubeMx since it's aware of all the possiblilities of the MCU.Then we manually need to transfer the pnout into Altium Designer Schematic. And to keep those in sync when design changes.So we want to automate that step if possible.Thus the question: How can I Import pinout generated from STM32CubeMx into Altium Designer Schematic.

hello ST Community,where can I set it to avoid generating the file "startup_stm32l5...zetxq.s" during compilation and debugging in the stm32CubeIDE environment and also how to avoid that the space bar "|" when editing the line of code of 'main.c' is automatically moved to the last line of code of 'main.c' during compilation and debugging. Where should I set it to avoid all this?Thanks so much for your support

Im trying to setup FreeRTOS with the new STM32N6.According to https://github.com/STMicroelectronics/x-cube-freertos, the new Nucleo board for the STM32N6 is mentioned as supported.But in the CubeIDE, when trying to enable the FreeRTOS middleware, it says that the new nucleo board is not supported. And the docs also only mention AzureRTOS as supported.Is FreeRTOS supported through the CubeIDE? Or only AzureRTOS? 

I have recently installed STM32CubeIDE 2.1.1 on linux and opened an existing project workspace. Everything looks fine except the integration with CubeMX for ioc files (which I believe is now by-design). The problem I have is after going to eclipse marketplace and installing Subclipse, it installs fine, then after restarting it goes into an endless loop saying the application is not responding. Finally, I got a message about "Failed to load JavaHL Library.", but I'm not sure if that's the real cause as dismissing the dialog reverts back to the application not responding loop.  Reinstalling the IDE does not help. The only way I've found to get the IDE to work is by removing the stm32 folder under $HOME/.eclipse, but this doesn't correct the issue with subclipse or its connection to subversion. Any help much appreciated.

Hello,I found a CubeMX database issue affecting STM32H747 dual-core projects using FreeRTOS with CMSIS-RTOS V2.EnvironmentMCU: STM32H747Cube/HAL: STM32CubeH7 1.13.xCubeMX: 6.17FreeRTOS: 10.6.2ProblemTwo FreeRTOS configuration parameters are not present in the MicroXplorer Configuration settings and are not retained in the internal IOC model:configUSE_SB_COMPLETED_CALLBACK configUSE_MINI_LIST_ITEMBecause of that, code generation can produce invalid output in FreeRTOSConfig.h such as:#define configUSE_MINI_LIST_ITEM ( valueNotSetted ) #define configUSE_SB_COMPLETED_CALLBACK ( valueNotSetted )This breaks the build and/or downstream FreeRTOS code.Editing the .ioc manually does not solve it permanently, because CubeMX overwrites the .ioc on regeneration.Adding manual defines in USER CODE blocks is only a local workaround and does not fix the root cause.Root cause foundThe issue appears to be in the CubeMX FreeRTOS mode database, not in the generated project itself.For STM32H747, CubeMX uses

Hello,I tried to install the STM32CubeMX2 on Linux Lite 6.6 which is base on Ubuntu 22.04, but get unsupport file error.I double check that I allow this file to run as a program. Is there any guide on how to install it on Linux? Thank you.

I am using a G474RE nucleo board and i have 2 separate interface boards which i ca connect to it. One board requires a VREFBUS of 2.5V and the other  2.90 . Currently i modify the .IOC file and select the appropriate VREFBUS, compile the code. So currently i have 2 separate .elf files, one for each scenario. I will want a single code version so that on start up based on the status of a switch connected to a GPIO, it will configure the correct VREFBUF value. The attachment shows my setup for the 2.90V internal voltage reference. Thanks David  

STM32CubeIDE 1.14.1I have imported a CubeMX generated makefile project.  When I enter the debug configuration dialog, I get an error "Unsupported build configuration. MCU ARM GCC required for debug." I have not found any documentation from ST indicating how to install this.  I am also curious why a dependency required to debug an ST MCU does not come with ST's Eclipse debugger. The Eclipse Marketplace returns an error 500 when I search for MCU ARM GCC.The Install New Software dialog just spins forever, not even loading any package data. What I'm looking to do:Debug an MCU application on my target board.I do not actually care about STM32CubeIDE, I am fine using stock Eclipse.  But I do need documentation on how to set up the actual ST specific debug tooling, and this information either doesn't exist or is difficult to find.  If ST's IDE works, that's fine too, I don't really care.

  I don't use this Tx Buffers Nbr. Instead, I use this Tx Fifo Queue Elmts Nbr for sending. The difference between the two is just that one is manually sent and the other is sent by hardware, right? Why does the software give me a pink prompt for Tx Buffers Nbr, stating that the number of Tx Buffers Nbr plus the number of Tx Fifo Queue Elmts Nbr must be 32? What does this mean? Help me, I'm about to cry.I don't use this Tx Buffers Nbr. Instead, I use this Tx Fifo Queue Elmts Nbr for sending.

I upgraded to 6.17 this morning an have already had to roll back due to a bug in how it now generates fiels for FreeRTOS.Under the FreeRTOS (Include parameters) options I have this vTaskDelayUntil set to Enabled.  This now changes the define name in the user config file (Core/Inc/FreeRTOSConfig.h) to be #define INCLUDE_xTaskDelayUntil 1which is correct for the updated freeRTOS version, but in the file (Middleware/Thrid Party/FreeRTOS/Source/CMSIS_RTOS_V2/freertos_os2.h) it has not been updated so it now it throws an error stopping my projects from building. There are other places where vTaskDelayUntil has also not been updated to xTaskDelayUntil. This needs to be fixed.  

Hello, I got following problem.STM32CubeMX is unable to properly generate .project file for STM32CubeIDE. After clicking "GENERATE CODE", MX is copying library files, generating .h and .c files, but no .project file. Following nullpointer exception can be found in log file. I already tested different versions of JAVA - no change. I attached error messages, MX log, and .ioc file. Anyone managed to fix this?  2026-03-15 10:27:00,707 [ERROR] ToolchainGenerator:531 - java.lang.reflect.InvocationTargetException: null at jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:115) ~[?:?] at java.lang.reflect.Method.invoke(Method.java:580) ~[?:?] at com.st.microxplorer.plugins.projectmanager.model.ToolchainGenerator.CallMethod(ToolchainGenerator.java:406) ~[?:?] at com.st.microxplorer.plugins.projectmanager.model.ToolchainGenerator.generate(ToolchainGenerator.java:506) ~[?:?] at com.st.microxplorer.plugins.projectmanager.engine.Pro

Hello,I tried to install STM32CubeProgrammer, but the installer always gets stuck at Step 8. I searched online and found that some people from my country solved the problem by changing the Windows region and language.However, my Windows 11 license only supports a single language, so I cannot change it.Is there any other solution for this issue?Thanks in advance.

Hi ST,I have a STM32H7 project with FW_H7_v1.12.1 and MX v6.16.1, everything is good so far.But after migration to FW_H7_v1.13.0, I can't generate FreeRTOS code any longer.All FreeRTOS-related code are deleted and MX stay loading icon when I click FREERTOS component.I tried uninstall MX and then install latest MX v6.17, but the same.I also tried install X-CUBE-FREERTOS component, but still the same.Please find my ioc file as attachment.Is there anything I can do?Thank you very much.BRs,-Engin

Split from Inconsistent pin naming - this is a separate suggestion.I would like the option to have the define of a particular GPIO port, or all defines, not typecasted to a pointer. So only the base address as an uint32_t (or uintptr_t). This would make using it in C++ in constexpr easier. Because reinterpret_cast and pointer comparison is not allowed in a constant expression. This should be an additional define for backwards compatibility.  #define CLK_A_GPIO_PIN GPIO_PIN_0 #define CLK_A_GPIO_PORT GPIOF #define CLK_A_GPIO_PORT_BASE GPIOF_BASE // <- for use in constexpr In C++ it would be much easier to do things at compile time using templates and constexpr this way. Example:you want to create a function at compile time that sets 2 defined pins highif they are the same port they can be combined in one call to GPIO_set()if they are not the same port they need to be separate callsno macros needed in user code, no runtime checks needed, no manual tweaks n

STM32C5 unlock RDP2 need OEM key, How to use STM32CubeProgrammer to set the OEM key and RDP0 to RDP2? Please provide me with a correct operation procedure. Thank you.  

Added dual-core to title - may be significant ...Hello.I've tried rename my project in the past, and this always generate a lot of errors due to the dependencies.Which is the properly way?I am working with STM32H755. Yes, dual-core.Thanks!

Hi there,I've been using the STM32H7R7 device (BGA225), but I ran into an issue. I used the TochGFX (4.26) to generate the gfx_task, and after that, I configured the cubemx (6.17), but somehow the linker was not good. Even my code could not be built since the external PSRAM was not set up automatically. I fixed it, but I ran out of ideas. I would highly appreciate it if the demo were to be available to move forward. Thank you very much!Geri

I am using an STM32H7 MCU and configuring the system clock to 400 MHz using CubeMX. The clock tree shows SYSCLK = 400 MHz, and MCO2 is configured to output SYSCLK.However, when I debug:HAL_RCC_GetSysClockFreq() returns 64 MHzRCC->CFGR shows SWS = 0 (HSI is used)SW = 0, meaning the system is not switching to PLL It seems that the PLL is not being selected or is failing to lock, and the system remains on HSI. I have configured PLL and SYSCLK source in CubeMX, but the change is not reflected at runtime.HAL_RCC_GetSysClockFreq() RETURNS 64MHZ
