Hello,I am an engineering student working on my senior graduation project using the STEVAL-WBC2TX50 evaluation board. I need the STSW-WBC2STUDIO (or the updated WPSTUDIO) GUI to configure the board, but all official links on the ST website return a 404 error.Could you please provide a working download link or the installer files? My project exhibition is approaching soon, and this is a critical blocker.Thank you for your support.

Are HAL drivers and/or LL driver available for SR5E1E3 or E1E5?Where can be found?I saw some HAL LL drivers fin the MCTK SR5E1x Motor Control Toolkit 1.3.0 folder in Stellar Studio (\StellarStudio-9.0\contrib\SR5E1_MCTK-1.3.0\) but they are not present for all peripherals.Drivers present in SDK are not HAL style and seems not complete Thanks

I have a STM32U585 (edit: ...VIT6, so not the one where this doesn't work due to errata) product with Trustzone enabled, Bootlock disabled and RDP level 0.I want to bring this into ST bootloader mode from software (for easy Firmware change via USB).To my understanding that would mean implementing the last entry of Pattern 12 from AN2606 

Hello,I am designing a high-speed data logging architecture using STM32H743VIHx. I would like the community to validate my DMA architecture and answer specific questions about eMMC access. I did not find answers in the forum and I am also not an expert in microcontroller hardware/software architecture. --- SYSTEM OVERVIEW ---The logging produces a continuous signal sampled by the ADC. I need to log raw data samples along with GPS and IMU data to an eMMC for post-processing.Key parameters:- ADC: 14-bit dual interleaved on PA6 (ADC12_INP3), differential ~10 MSPS effective- eMMC: S32 GB, eMMC 5.1- SDMMC1 in 8-bit MMC mode- IMU: on SPI2 (PB12-15) at 8 kHz- GPS: on UART4 at 115200 baud --- PROPOSED DMA ARCHITECTURE ---Four concurrent DMA paths:1. ADC1+ADC2 interleaved → DMA1_Stream0 → AXI SRAM (ping buffer)Triggered by ADC1 EOC, reads CDR register (32-bit = 2 interleaved samples)

ST moderator: updated the title to be more concise according to the below exchanges. Hello All,   I am facing a problem for debugging one of the board which uses stm32h7 controller. I am not sure why this is happening but on other board I am able to debug it, but for first one its not working. Though the code and debug config settings are same for both the board and using same system to debug both, but on one board I am able to debug while on other its is not. so could you please tell me what I can try to resolve this issue.   Thanks, SD 

STM32CubeMX v6.17.0While configuring an STM32CubeMX project for an STM32H753 Ethernet project on a NUCLEO-H753ZI, I observed some strange behavior.After enabling memory management, including the checkboxes- Apply Application Regions Settings to Peripherals and- Apply Application Regions Settings to Linker Files,I would have expected the memory regions to be included in the linker description file STM32H753XX_FLASH.ld.Unfortunately, this was not the case.However, since the STM32H753XX_FLASH.ld file had obviously been regenerated, I did not suspect the file handling itself.After several hours of searching, I discovered that if the .ld file is deleted before regeneration, different content is generated.Steps to reproduce this:Open STM32CubeMXFile / New Project… / Board SelectorSelect NUCLEO-H753ZIIn „Board Project Options“ dialog, click button „Unselect All“S

  Hello ST Community,I am working on STM32H7B3LIH6Q with TouchGFX.I have successfully initialized the TFT RGB display on hardware, and the RGB test output is working properly. I created two screens in TouchGFX Designer, where pressing a touch button on Screen 1 should open Screen 2.This works correctly in the PC simulator, but on actual hardware the touch command/button press is not working. The display is visible, but touch input is not detected.I have attached the hardware output image and my touch enable/source code for reference.Could anyone please suggest what I should check in the hardware touch interface? Is the issue likely related to , BSP touch driver, I2C touch controller initialization, or touch coordinate mapping?Thank you,Vijaya.

Hi, I have all configured using internal loop FDCAN1 and there is not working on my STM32G474RE-Nucleo board 

Hi, We are busy making a setup with 2 nucleo-c092rc boards. Our first test was to send from board 1 to board 2 by the integrated CAN interface on these boards. We started at 1Mbits and this worked great. Also on 4Mbits the setup worked great. But we also want to test this on 8Mbits and now the transmitter is not sending correctly. We only see that the arbitration phase is send out and a couple of bits of the data part, but then the transmitters stops sending. We have tried with internal HSI(48Mhz) and external HSE crystal which is also 48Mhz on the nucleo boards.  We calculated the values for the SyncJumpWidth and timeseg1 and 2 and also tested with values slightly altered. hfdcan1.Init.DataPrescaler = 1; hfdcan1.Init.DataSyncJumpWidth = 2; hfdcan1.Init.DataTimeSeg1 = 2; hfdcan1.Init.DataTimeSeg2 = 3; But we allways have the same outcome. Sometimes it's not sending anyth

Hello,I am evaluating the STMicroelectronics IIS2MDC magnetometer and measuring its supply current using a Joulescope. According to the datasheet, the device should draw approximately ~1.5 µA in idle mode, yet I consistently measure about 450 µA, which is far from the specified behavior.Test setup & observationsSupply: 3.0–3.3 V (also tested across the allowed 1.71–3.6 V range).Measurement instrument: Joulescope (µA resolution).Verified results across multiple PCBs and multiple IC samples.Tested the sensor stand-alone (no MCU connected, only power rails).Same behavior observed on the STMicroelectronics evaluation board.Datasheet behav

This is some feedback for the STM32C5 OEMiRoT example provided by ST.This is based on the STM32C5-MCU-HAL2.0.0 pack download 06-05-2026.Attached you can also find the CMake Config files for the example, specifically for the NUCLEO-C542RC board.General Bug Provisioning Python ScriptThe provisioning python script has a small bug when it comes to the prebuild script which adjusts the linker files.These files are compiler specific so the correct adjustment function needs to be called.This compiler dependent code is missing in the `_update_linker_define()` function in `STM32C5-MCU-HAL/rot/rot_provisioning/helper/project/project_generic.py` starting at line 318:linker_path = self.config.get_compiler_linker(compiler) value = f"0x{self.flash_layout.get_flash_layout(define):X}" update_define_in_file(linker_path, define, value)

Hello, ST expert For GPIO structure, what are the differences between FT and TT mode? Are there any differences for the ESD diode and the other diode in these two modes?     BR Yang  

Hi, I am working on a TPMS project and I have migrated from FXTH to NTM88. With the FXTH I was using the MKW01 board for RF communication, on the NTM88 side, to use the same RF board I need the Starter Package for NTM88 and MKW01. The link can be found on NXP website but doesn't work. I have been advised to get in touch with you as the NXP MEMS sensor products have been transitioned to you since February 2026.   I have also search on ST website but with no luck. Would it be possible to advice how can I get hold of the info from the NTM88 and MKW01 package?   Regards,Mihnea

I am working on UART communication between an STM32H563 and a Raspberry Pi CM4.Currently, I am using UART without hardware flow control (RTS/CTS disabled). During continuous communication, I am frequently getting ORE (Overrun Error) on the STM32 side.Configuration details:MCU: STM32H563Communication: UARTFlow control: DisabledUART mode: InterruptPeer device: Raspberry PiI would like to know:1. What is the best workaround to avoid ORE errors without enabling hardware flow control?2. Is it reliable to use UART communication continuously without RTS/CTS?3. What are the recommended UART settings or software handling methods for STM32H5 series?4. How should ORE recovery be handled properly in STM32H563?Currently, once ORE occurs, The data became lost.

Is there anyway to increase the size of the icons in the top menu bar in the IDE?I am 70 now and my eyesight needs a wake-up here :)

Hi All,I've just been watching an ST tutorial video on how to implement  bare-metal Device CDC USB  on an STM32U3.During the video, the lecturer says that the code is available within the workshop download. No link is provided to the workshop code....Does anyone know where I can find it? This is the video in question : https://youtu.be/m8ph9JIY5QE?list=PLTJzs51NlEIAHFfePhKJPsnWvT5XidJuU&t=1164Any help would be appreciated.CheersMichael 

Hello ,I am working on a project with the STM32L562CET6 microcontroller and have encountered an issue with the timer interrupt callback function.   1. I configured TIM6 as the clock source for the microcontroller. Consequently, the HAL_TIM_PeriodElapsedCallback() function is automatically triggered whenever the TIM6 interrupt occurs.   2. Now, I have configured TIM2 for a different purpose, but I noticed that when the TIM2 interrupt occurs, the same HAL_TIM_PeriodElapsedCallback() is triggered.Since the HAL_TIM_PeriodElapsedCallback() is defined with the weak attribute, I understand that I can redefine it in my user code. However, this causes conflicts when multiple timers (like TIM6 and TIM2) trigger this callback.Questions:  1. Is there a way to alias or redirect the HAL_TIM_PeriodElapsedCallback() to separate functions for different timers (e.g., one for TIM6 and another for TIM2)?  2. Is there any othe

Hi All,    I want to do something very basic, but somehow cannot manage to do it. What happens if you have a PWM signal on an IO Pin, generated by a timer, and you disable the timer?  What happens to the physical IO Pin ? Is it stuck at the state where it was when you disabled it ?, Does it go Low ? Or High. The Idle state of the Timer is Low, and the On state High.    Thanks,  DJ 

Hello, I'm trying to convert a project to vscode the first error I incurred to was this one: I'm trying to convert to cmake using the extension a project for the STM32U585OIYXQ, when I load the source folder and set the output folder then i push on convert and this is the output that I get :   [Error] [ide-project-convert]:Generating project... [Error] [ide-project-convert]:The specified 'STM32U585OIYxQ' device is unknown [Error] [ide-project-convert]: Project conversion failed with exit code: 35. Which has been solved with this work around: "you can enable the stm32cube-ide-project-manager.conversion.ignoreMissingDevice VS Code setting".That went through and I have the following new error: [Info] [project-manager] STM32CubeIDE project manager activation....

I am trying to learn how to program a STM32 micro-controller, specifically a STM32C593. The thing is according to its datasheet it has Ethernet functionality, bit it is missing in the peripheral list inside STM32CUBEMX2 IDE. 

Hello ST Community team,I would like to report a possible inconsistency in the STM32 MCU Portfolio Selector regarding Ethernet filtering for the STM32C5 series.While selecting MCUs using the Portfolio Selector, I filtered devices through:- EthernetThe reference STM32C593CET6 appears as supporting Ethernet functionality. However, according to DS15136 (Table 1), this specific MCU does not include the Ethernet peripheral.This may create confusion for developers, especially since the STM32C5 family is still relatively new and many users rely on the Portfolio Selector during early device selection.Could you please review and correct this behavior.Ps: more details available on this post. Best Regards.II

Hello!I am having trouble verifying NPU operation on the NUCLEO-N657X0-Q board.I am trying to test a simple INT8 FNN (Feed-Forward Neural Network) using an ONNX model. The project was generated via X-CUBE-AI within CubeMX. I have configured the AXI and Clock settings (CPU: 600MHz, NPU: 800MHz, NPU AXI: 800MHz) and, given the model's simplicity, I set it to use internal SRAM only.While the code execution seems to flow correctly without errors, I noticed that the output values are not being updated. The output buffer remains unchanged, or in some cases, still holds values that look like the input data. It seems the NPU's computation results are not being written back to the memory correctly.I would greatly appreciate any advice or suggestions, even if they aren't complete solutions!Environment Versions:

Hello everyone,I am currently working with the Aliro software expansion for STM32Cube using the new STEVAL-ALOCKCB board (Aliro access control reference design based on STM32WBA65RI, ST25R300, and STSAFE-A120).Both the hardware and software are in their original, unmodified state from ST. The nfc12ble project builds successfully without any issues.However, I am encountering a consistent problem:the function CryptoInit() always returns false.From debugging, I can see that the failure originates from the CheckReaderPubK() function, which internally calls isValidProvisioning(). This function also returns false, causing the entire initialization to fail.It seems that the provisioning structure is not considered valid. In particular:The check prov->isValid == DEVICE_PROVISIONING_STRUCT_IS_VALID fails.DEVICE_PROVISIONING_STRUCT_IS_VALID

Dear STMicroelectronics Community / Support Team,I hope you are doing well.I am currently working with the STM32N6 Discovery Kit and noticed that it uses an external Octal NOR flash device with the part number MX66UW1G45G. However, I have been unable to locate a public datasheet for this exact component.I was able to find datasheets for similar parts such as MX66U1G45G and MX66UM1G45G, but not for the “UW” variant used on the board. This has led to some confusion regarding the exact specifications, supported features, and command set of the device.I would appreciate your guidance on the following points:Is MX66UW1G45G a custom or internal part number used specifically for STM32 evaluation boards?Is there a publicly available datasheet for this device, or can it be s
