STM32CubeIDE (MCUs)

BackgroundI have developed firmware for a LoRaWAN device by modifying the LoRaWAN_End_Node example for the B-WL5M-SUBG1 development board, which was extracted from the STM32Cube MCU Package for STM32WL series (v.1.3.0) from ST's website (not through CubeIDE). Based on this, I have further developed a custom PCB containing the STM32WL5MOC and other peripherals (antennae, RTC, LEDs, buzzers, etc.). SituationTo test the custom board, I have flashed the STM32 chip with a simple firmware which toggles the GPIO pins based on button presses - this works as intended. However, when I flash the LoRaWAN_End_Node example for B-WL5M-SUBG1 (downloaded from STM32CubeIDE v.1.18.1) onto the STM32 chip, the device was able to join the LoRaWAN network once, but failed subsequent joins due to a repeated nonce. After numerous failed attempts at fixing this, I went back to the example code downloaded from CubeIDE, and now my LoRaWAN server cannot even receive a join request.When looking at the current

After editing the .IOC file, the code generator will mess up the app_usbx_device.c\MX_USBX_Device_Init() function by placing the codeif (ux_device_stack_initialize(...)right after the variable declarations at the top of the function.Typically, that function call should be around line 151 after 6 other function calls initialize all the pointer variables.The end result is 8 compile warnings about using uninitialized variables.Attempts to wrap the stack initialization in /* USER CODE BEGIN MX_USBX_Device_Init0 */ don't work, and the code generator will just move it to the top of the file anyway.What is the work-around for this?STM32H562VGTxSTM32CubeMX 6.12.0STM32CubeIDE 1.16.0 

Board:STM32U5A9xxI set the Number of PDO to define = 5 in the cubeide.But after generate code, the code in usbpd_pdo_defs.h, macro:PORT0_NB_SINKPDO is still 1U.I also checked the file usbpd_pdo_defs_u5.ftl in cubeide's location, the macro PORT0_NB_SINKPDO is a value param from cubeide indeed, but it seems not effective. Is a bug?/* Define ------------------------------------------------------------------*/ #define PORT0_NB_SOURCEPDO 0U /* Number of Source PDOs (applicable for port 0) */ #define PORT0_NB_SINKPDO 1U /* Number of Sink PDOs (applicable for port 0) */ #define PORT1_NB_SOURCEPDO 0U /* Number of Source PDOs (applicable for port 1) */ #define PORT1_NB_SINKPDO 0U /* Number of Sink PDOs (applicable for port 1) */ 

The goal is to test the Adafruit Gamepad QT with the Nucleo-G071RB board. This requires using the Adafruit seesaw C++ library of source files, which transmits analog joystick signals using the I2C protocol.I used the code example I2C_TwoBoards_ComPolling (C-code) as a starting point an...Added both the Adafruit seesaw and BusIO libraries (C++ code) to the project,Updated the Project Include paths,Added the library paths to the Project Source Locations (Figure 1), andRenamed the main.c file to main.cpp.Problem: the project does not built the Adafruit libraries, the compiler just ignores them.What is the solution for this? How do I build the entire project, including the Adafruit libraries? Thank you!!!Figure 1. 

Working with getting TraceRecorder to work with an L562 project.  When the tracerecorder software is added (using the package), SYS_DBG_ENABLE_TA4 is set to 0, which inactivates the feature.  SYS_DBG_ENABLE_TA4 has to be manually set to 1 to enable the feature.  So far, so good.  Get it working, and then decide to make a change to the .ioc file.  exit configurator.SYS_DBG_ENABLE_TA4 is reset to zero.If it is set, PLEASE leave it that way, since it makes no sense to reset it.  Amazing the number of errors you can get on default settings (like streaming mode taking almost half a megabyte of memory or more).I'm regarding this as a bug.Thanks.

  I have been trying to deploy a simple ML model on my STM32 NUCLEO H755ZIQ, i've been following a tutorial as am learning right now, but no matter how many times i try i cant seem to shake of these three errors:1. when i try to open the XcubeAI  interface a dialogue pops up saying setting up USART3 but it never stops loading, i suppose its a bug but i leave it to the experts to decide what it is. 2. when i try to validate the code on target board, it gives an error: E200(ValidationError): TARGET: Unable to bind the ST.AI runtime with "network" c-model: []E801(HwIOError): Invalid firmware – /dev/cu.usbmodem11403:1152003. When am trying to build the model i got this error: error: unknown type name 'ai_i8'error: unknown type name 'ai_handle'fatal error: bsp_ai.h: No such file or directoryPlease help me out and guide me how to run this basic project on my board i found on the internet: https://github.com/stevemac321/5_Class_Embedded_Keras/tree/maini

Hi,i just generated a project using the Device Configuration Tool (1.19.0). All works. But as soon as I enable "Generate peripheral initialisation as a pair of '.c/.h' files per peripheral" the hardware stands at:static HAL_StatusTypeDef USB_CoreReset(USB_OTG_GlobalTypeDef *USBx) { __IO uint32_t count = 0U; /* Wait for AHB master IDLE state. */ do { count++; if (count > HAL_USB_TIMEOUT) { return HAL_TIMEOUT; } } while ((USBx->GRSTCTL & USB_OTG_GRSTCTL_AHBIDL) == 0U); count = 10U; /* few cycles before setting core reset */ while (count > 0U) { count--; } /* Core Soft Reset */ USBx->GRSTCTL |= USB_OTG_GRSTCTL_CSRST; do { ////loops forever here?!?!?! count++; if (count > HAL_USB_TIMEOUT) { return HAL_TIMEOUT; } } while ((USBx->GRSTCTL & USB_OTG_GRSTCTL_CSRST) == USB_OTG_GRSTCTL_CSRST); return HAL_OK; } I had no closer look into what is done differently. Just wanted to report the issue. Again, if everything is inside of

Hi, 1. I want ti have auto view change for C, MX and Debug windows. Previously a promt used to come. Now I dont see that.2. I want to generate MX automatic on save. Previously a promt used to come. Now I dont see that. 

Hello,Dear ST,As a Big fan of yor MCU and everything based on eclipse please give possibility to disable in SFR view particular register or peripherals. Now without this possibility debugger can without my intention clears some flags (witch are cleared by reading some register) And please fix already Life View ;)  

I created a static library using STM32Cube IDE and included it in a non-library project. Both projects build with no errors or warnings, and the application that uses this library runs correctly. My next step was to create an additional static library project and include the original static library in it. I can find no way to do this in STM32Cube IDE. Can anyone point me to project properties for a static library that will allow me to use a different static library I created?

Hello EveryoneI am using the latest STM32CubeIDE i.e. 1.10.1, and I am facing a strange problem.In the register view of the Special Function Register, I have a problem.As can be seen above the RCC->CR register value is 0x30006783This means that Bit 28 and Bit 29 are set, these bits are PLLSAIRDY and PLLSAION, but here it looks like some wrong mapping is done, these two bits are not shown in the SRF viewCan someone please suggest why this is happening, am I doing something wrong?

Hi all,I'm trying to create a new STM32CubeIDE project for the STM32N6570-DK board and use the BSP drivers. For now I'm just trying to do something simple like display camera output on the onboard LCD (or something simpler like displaying text on lcd). I’ve already added the driver files and their dependencies to my project. For the conf template files, I just renamed them without changing content.To get the project to build without errors, I had to manually uncomment the following in stm32n6xx_hal_conf.h:#define HAL_DMA2D_MODULE_ENABLED #define HAL_LTDC_MODULE_ENABLEDNow, I’m following the initialization sequence from the STM32CubeN6-v1.2.0 example projects and calling the following in main.c:BSP_LCD_Init(0, LCD_ORIENTATION_LANDSCAPE);UTIL_LCD_SetFuncDriver(&LCD_Driver);UTIL_LCD_SetFont(&UTIL_LCD_DEFAULT_FONT);UTIL_LCD_SetBackColor(UTIL_LCD_COLOR_WHITE);UTIL_LCD_Clear(UTIL_LCD_COLOR_WHITE);These functions do not return errors, and I can step over them in debug mode,

I just started to look into this chip for a new project, so I decided to try to build a sample program in the Cube IDE. It seemed to work until I tried to enable I3C. Now the build system is complaining about missing files. The missing file is 'stm32h7rsxx_util_i3c.h', the error is '.../Drivers/STM32H7RSxx_HAL_Driver/Src/stm32h7rsxx_util_i3c.c':20:10: fatal error: stm32h7rsxx_util_i3c.h: No such file or directory'. Where can I find this file and where do I put it? Any help is appreciated, thanks.

Hello All, I am trying to use the SWV Statistical Profiler in STM32CubeIDE while debugging a stm32H7. I am also using ThreadX RTOS for the project.  I am getting debug output from the SWV Trace Log.  But nothing is appearing in the SWV Statistical Profiler.  The RED button is not grayed out - but it also does not log anything after pressing record when debug is paused. and then resuming.I have ITM Stimulous port 0 checked and PC Sampling and Timestamps checked, as well as EXETRC checked. I am wondering is this something that is disabled when using an RTOS?  I understand that the output will be spread between tasks. I am also running STMCubeIDE on linux. Any Help/Tips AppreciatedThanks,-Trevor         

Hello all.Im starting to work with the Nucleo L476RG board and am now at the stage i would like to bring up the CAN bus. I haven noticed there are CAN bus examples available for other Nucleo baords but not in the current STM32Cube_FW_L4_V1.18.1 for the L476. Is this available or been ported to the L476?Many thanksRich

Hi @stforum  @stforum2 @Mahmoud Ben Romdhane Good evening.I am working on an STM32F765VGT6 microcontroller using STM32CubeIDE v1.19.0 on Windows 10 Pro. The project requires enabling both Ethernet (ETH) and USB Custom HID functionalities.  On 22 July 2025, I received an email from the ST Community recommending an update to STM32CubeIDE. At that time, I was using v1.17.0, and I proceeded to update to v1.19.0 as advised.Problem Faced:Today, I encountered an issue where the middleware files related to LWIP and USB HID became corrupted, even though I was working in a different workspace.Due to this corruption, I am unable to restore my previous working code and also unable to access Ethernet and HID functionalities.This issue has occurred after updating to STM32CubeIDE v1.19.0.Now neither i can get back older version of code nor creating a new one which is working.Request for Assistance:Could you please advise on how to resolve th

I am successfully using all the SWV debugging functionality in STM32CubeIDE except for the ITM functionality, as described in UM1609 and in the advanced debugging videos on youtube from ST.I have both tried overriding the "_write " function in main.cpp or replacing "__IO_putchar" with "ITM_SendChar" in syscalls.c, but I don't see any output when using printf and ITM port 0 (described in video 4 and section 4.3.5 in UM1609).I have further tested sending output to ITM port 31, as described in video 5, but still cannot see any output.Some details and further questionsSWO is left unconnected - Do I need to connect the SWO to some other pin to make ITM work?I am running at 180 MHz clock speed - Is this too fast for ITM?Does it matter if I compile for cpp rather than c?Are there any benefits to updating an ITM port, like in video 5, rather than updating a global variable and observing the execution order by looking at a graph in a SWV Data Trace Timeline Graph or in CubeMonitor?Any further s

My autoomplete shows "no default proposals" when plrssing CRTL+Space and do nothin when typing "." or "->" or any other trigger...Some people solved this enabling "Parsing-based Proposals" in the "Content Assis -> Advanced" tab but mine is enabled and not working... I've tested a lot of things and the ContentAssis still not worling... Any help???Thanks

I am encountering a persistent flash programming issue on the STM32L452RE microcontroller using STM32CubeIDE and STM32CubeProgrammer. The device is connected via an ST-LINK V2 debugger using the SWD interface. The problem occurs during firmware flashing: although the flash erase operation completes successfully, the subsequent write operation fails consistently with the error message “Error finishing flash operation”. This issue is reproducible across multiple boards of the same model.Development Environment:MCU: STM32L452REIDE: STM32CubeIDE v1.15.1Debug Probe: ST-LINK V2 (latest firmware)Debug Interface: SWD at 3.3VTools also used: STM32CubeProgrammer v2.xRDP Level: 0xAA (Debug enabled, fully open)Boot Configuration:Bootloader: located at 0x08000000 (32 KB region)Application: located at 0x08008000 onwardsLinker scripts: verified for non-overlapping memory sectionsFirmware size: well within the flash limits of the deviceObservations:Using STM32CubeProgrammer:The chip is correctly detec

I've got a project that has the following files in the tree view:All is well if I clean and build, but if I open the .ioc and "Generate Code", the tree changes to:and the project then fails to build due to a duplicate system_stm32g0xx.c file.Why is this getting added and how do I stop it?I am using STM32CubeIDE V1.18.1.

I have a FreeRTOS project but I cant use xTaskCreate even though its in the paths list (see image below)Frustratingly this is the exact same set up I was using last week in a similar project that worked but today.... no dice.Why isn't the compiler finding the references? They all exist in the directories in the paths & includes list. In fact if I right click & ask to find the definition Cube quite happily opens the correct file, so why cant the compiler find them?I check that the flag for the xTaskCreate define was set correctly (it is).EDIT :: User error, I forgot to delete the GCC folders for all the other ARM_CMxx processors that I'm not using. Hence I was getting what were in fact multiple define errors.

As described in this post during installation of CubeIDE on Ubuntu 24.04 an error is presented because libncurses5 is not available for Ubuntu 24.04. This can be worked around by using the generic installer. When attempting to upload firmware to an MCU, however, the same error message is given (it is shown as "Could not determine GBD version", but in details the missing libncurses5 is shown). The solution to a similar problem is given in this post, but the solution does not work for the CubeIDE as it requires a specific version of libncurses to be installed.Any suggestions would be greatly appreciated!

Hi everyone, I'e been working with a fw stm32 MCUs products in the last years and I want to decide which is the best way to proceed in the "update to latest version" of CubeIDE.The point is: once i start a project, I usually keep the same CubeIDE version till the end, just to avoid regressions during time-stringent situations. At the end, I feel the need to update to the latest available "to be sure to have all latest bug-fixes" before starting a new one, even though the updates might not impact on my work.This need always, and I mean it, always end up with me uncovering as we say "hot water", some bugs (as live expression bug in 1.19.0) and running to recover from the heartache, picking all modifications applied on a new project (thank you git) started in an older "more reliable" version of CubeIDE.As of today my main question might be: based on your experience, among the last couple of years releases which is the most reliable version of CubeIDE you have used? Is it that bad my
