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 t

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

Title edited to indicate that this is specific to J-Link.Hi,After updating to STM32CubeIDE 2.1.0 I get the following message after starting a debug session. Live expressions do not work.From the console:SEGGER J-Link GDB Server V9.14a Command Line Version JLinkARM.dll V9.14a (DLL compiled Jan 28 2026 17:11:52) Command line: -port 2331 -s -device STM32F769NI -endian little -speed 4000 -if swd -swoport 2332 -vd -rtos C:\ST\STM32CubeIDE_1.11.2\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.external

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

HiAs I experienced some problems with 2.1.0, I reverted to 2.0.0 and in that process I seem to have gotten the error:Program "gcc" not found in PATH - "[Discovery options] page in project properties"I followed the instructions found in the stm32CubeIDE user guide https://www.st.com/resource/en/user_manual/um2609-stm32cubeide-user-guide-stmicroelectronics.pdf, but the problem persists.Is there a way to manually clear this from any of the configuration XMLs perhaps?The code does still compile and creates binaries, so the error is just a nuisance.[Edit] spellingBest regardsMartin 

在官网下载的CLT工具链安装包，管理员运行后显示如图报错该怎么办？

I updated the STM3CubeProgrammer to version v2.22.0, and after restarting the app, it started showing a blank page. I was also not able to close the application directly. I had to end the task from the task manager. I uninstalled the latest version and installed v2.20.0, but it is also showing a blank page. Also, in STM32CubeIDE, I am not able to run and debug code. It gets stuck at  "Download in progress". Are both problems related?

Code generation of the attached .ioc file (copy of ST example file of similar name) does not generate clock init for UART4.  This means the example application hard faults.  I see no reason why the UART clock should not be initialised here and would save someone time debugging in the future!In stm32mp2xx_hal.c:void HAL_UART_MspInit(UART_HandleTypeDef* huart) { GPIO_InitTypeDef GPIO_InitStruct = {0}; if(huart->Instance==UART4) { /* USER CODE BEGIN UART4_MspInit 0 */ // TODO: Need this here! __HAL_RCC_UART4_CLK_ENABLE(); /* USER CODE END UART4_MspInit 0 */ /**UART4 GPIO Configuration PH8 ------> UART4_RX PH7 ------> UART4_TX */ GPIO_InitStruct.Pin = GPIO_PIN_8; GPIO_InitStruct.Mode = GPIO_MODE_AF_PP; GPIO_InitStruct.Pull = GPIO_NOPULL; GPIO_InitStruct.Alternate = GPIO_AF4_UART4; HAL_GPIO_Init(GPIOH, &GPIO_InitStruct); GPIO_InitStruct.Pin = GPIO_PIN_7; GPIO_InitStruct.Mode = GPIO_MODE_AF_

Hello,I found a bug in STM32CubeMX code generation for STM32H7S3.When configuring Ethernet with external clock input (ETH_CLK pin,PD6 with AF4_ETH) as PHY clock source, CubeMX does not generateGPIO initialization for this pin in HAL_ETH_MspInit().Workaround - must add manually:__HAL_RCC_GPIOD_CLK_ENABLE();GPIO_InitStruct.Pin = GPIO_PIN_6;GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;GPIO_InitStruct.Pull = GPIO_NOPULL;GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;GPIO_InitStruct.Alternate = GPIO_AF4_ETH;HAL_GPIO_Init(GPIOD, &GPIO_InitStruct);Without this, Ethernet does not work even though all otherETH pins are correctly initialized by CubeMX.Steps to reproduce:1. Select STM32H7S32. Enable Ethernet (ETH)3. Set clock source to external clock via ETH_CLK pin (PD6)4. Generate code5. ETH_CLK pin GPIO init is missing in generated codeCubeMX version: 6.17.0

Please use English on this forum.Translated: The development board is STM32H723, using stm32cubemx for development, debug is disabled, using stlink to burn found that it can be burned, and it can also be debugged, which is very strange! (The development board is STM32H723.) It was developed using STM32CUBEMX. The debugging option is set to "Disabled". Programming with stlink, discovering that it can be programmed and debugged. It's weird! ）Original:开发板为STM32H723，使用stm32cubemx进行开发，debug勾选禁用，使用stlink烧录发现可以烧录，并且还可以调试，非常奇怪！（开发板是STM32H723。它是使用stm32cubemx开发的。调试选项设置为“禁用”。使用stlink进行编程，发现可以编程，也可以调试。这很奇怪！） 

I am facing an issue in STM32CubeIDE on Windows where the I/O Configuration / Pinout & Configuration window is not appearing after creating or opening a project.Normally, when opening the .ioc file, the Device Configuration Tool (CubeMX interface) should open showing the MCU pin diagram and peripheral configuration options. However, in my case, this interface is not appearing.Issue Details:Operating System: WindowsSoftware: STM32CubeIDEWhen I create or open an STM32 project, the Pinout & Configuration view does not open.The .ioc file either does not open correc

Hi,I am using the STMH745 MCU and trying to synchronize the ADC trigger to HRTIM. For HRTIM I set the "ADC Trigger Configuration" as given in figure HRTIM.jpg - it defines only a SINGLE trigger. However, in ADC configuration (figure ADC.jpg), TWO HRTIM trigger outs are visible.Can anyone explain the relation between these two option sets? How to correctly synchronize the ADC trigger to the given value value of a HRTIM timer?Thanks!

Hi,When I worked on the Discovery kit with STM32F769NI MCU it supported in the STM32CubeIDE/MX the  LWIP package (from 2025) with FreeRTOS/V1. Now when I pass my project to NUCLEO-H563ZI I see in the TM32CubeIDE/MX that ST will not support the LWIP with FreeRTOS anymore. FreeRTOS is only v2 in this board.Is someone integrete the LWIP package on NUCLEO-H563ZI with FreeRTOS/v2? The code main files that should be changed from STM32F769NI to NUCLEO-H563ZI  are LWIP/App/lwip.c, LWIP/Target/ethernetif.c/h, LWIP/Target/lwipopts.h, main.c.Is there any project in git that have done this miggration for LWIP package (code from 2025) and using FreeRTOS/v2 in it's LWIP package? Or share with me those 4 LWIP files for NUCLEO-H563ZI board. Thanks.

Hi everyone,I just started developing software for a new project containing on of the STM32L4P5 series microcontrollers. Therefore I bought the NUCELO-L4P5ZG starter-kit to get used to the IDE, HAL and so on. I use the STM32CubeMX IDE (Version 6.16.1) to configure the board and generate the basic initialization sources. Further code writing is done in STM32CubeIDE (Version: 2.1.1).For the beginning I configured three GPIO pins for the LEDs on the board and the LPUART for simple data transfer to terminal on host computer. For the transmission I want to use DMA . After generating the code with CubeMX and implementing some simple blink logic for the LEDs, I added the line HAL_UART_Transmit_DMA(&hlpuart1, buffer, 14); to the main loop. I debugged the code and saw that the code ran into the infinite loop in the DefaultHandler in the startup file startup_stm32l4p5zgtx.s: After searching for two and a half hou

See Inconsistent pin naming for CubeMX - does the same apply to CubeMX2 ?   (Cross-posting at the request of @Ghofrane GSOURI; again, no label available for "Suggestions")

Hi. I want to use the A HRTIM timer to independently control two MOSFETs. Namely, I have a transformer with the midpoint connected to the positive pole of the power supply, and these two transistors switch the 2 halves of the winding as lower switches to generate 2 half-waves of a sine wave.But I can't configure it in STN32CubeMX for the second output the condition for set. STN32CubeMX "Set Sources: nothing to set as Dead Time is enabled, Output2 signal is defined based on Output1 Configuration Set Sources must be 0." although the channels are configured as independent. Moreover, before the update there was no such problem. Now STM32CubeF3 Firmware Package V1.11.5Why the problem?

I've always found it a little irritating:#define CLK_A_Pin GPIO_PIN_0 #define CLK_A_GPIO_Port GPIOFWhy is it deemed necessary to have "GPIO" in one, but not the other? Surely, that should be either:#define CLK_A_GPIO_Pin GPIO_PIN_0 #define CLK_A_GPIO_Port GPIOF("GPIO" in both), Or:#define CLK_A_Pin GPIO_PIN_0 #define CLK_A_Port GPIOF ("GPIO" in neither) (There isn't a label for "suggestion" - so "bug report" is the nearest option)

Hi, I am not sure how to categorize this problem. I have a custom board that I had done an initial software development cycle on STM32CubeIDE. I am working a newer version in VSCode with the STM32 Extension. Everything is working with the exception of one problem. I am using a watchdog on my MCU (STM32L4R9ZGJ6), which triggers while I have the processor halted. I know how to fix this in CubeIDE (Debugger tab, Enable Suspend Watchdogs) but cannot figure it out on the VSCode/GDB side. Below is the launch.json I have so far:{ "version": "0.2.0", "configurations": [ { "cwd": "${workspaceFolder}", "executable": "./build/debug/build/test.elf", "name": "Debug with ST-Link", "request": "launch", "type": "cortex-debug", "runToEntryPoint": "main", "showDevDebugOutput": "none", "servertype": "stlink" }, { "name": "Launch", "type": "cppdbg", "request": "launch", "cwd": "${workspaceFolder}", "program": "$

Hi I have created a project using STM32Cube.AI Studio. I am able to successfully run and generate the project from the tool. After that, I can open the project in STM32CubeIDE and build it without any issues.However, while debugging, I encounter the error shown in the image below.I am able to debug the image classification and face detection sample projects provided by ST without any issues. Therefore, I suspect that there may be a problem with the project configuration generated by STM32Cube.AI Studio.The evaluation board I am currently using is the STM32N6570-DK.Please help me to resolve this issue?

I am experiencing a problem with RTOS Proxy in STM32CubeIDE 2.0.0/2.1.0 when debugging a ThreadX application on STM32H753 using a SEGGER J-Link.The same setup works correctly with STM32CubeIDE 1.19.0, but after upgrading to 2.0.0/2.1.0 the debugger aborts during the flash download when RTOS Proxy is enabled. If I use J-Link Kernel Awareness instead RTOS Proxy everything works fine.ConfigurationMCU: STM32H753BIRTOS: ThreadXSTM32CubeIDE: 2.0.0RTOS Proxy: ThreadX / Cortex-M7Debug probe: SEGGER J-Link Ultra+J-Link GDB Server: V8.80Interface: SWDDebug configuration:RTOS Awareness: EnabledRTOS Kernel Awareness: RTOS ProxyRTOS: ThreadX (Cortex-M7)

Hello, I am using the STM32H503 MCU. When I configure the pins as follows:PB2 → OUTPUTPA8 → TIM1_CH1PB7 → I2C1_SDAIn the RCC section, I get red warnings for Master Clock Output1 (MCO), LSCO clock output, and SAI1 External clock. I cannot disable these clock settings. Is there a way to do this in CubeMX? How can I resolve this conflict in CubeMX?

I am using STM32CubeMX (Version 6.17.0). Here is what happened. I created a PIN name "CLK-A". After some troubleshooting, I found a mistake in my pinout definitions. I named the correct pin as "CLK_A". However, I did not delete the "CLK-A" pin. When the C code was generated for the project, the "CLK-A" pin was defined as "CLK_A" in the output C file. The tool did not flag me that there were two pins with the same effective name. It took me some time to track down the issue. Once I deleted original "CLK-A" pin definition, my design worked. I added "CLK-A" back to the design on another pin". I got "CLK_A<pin name>" in the "header.h" file. The first pin defined seemed to have priority.
