Hello community,I just wanted to know whether you know of a clock tree wizard for SPC58xE.I read in one post some years ago that there is no clock tree wizard for SPC58XE, but is there still none?Is there any possibility to visualize the clock connections? Kind regards Tkorn

Hello Team,  Since SCB and other core registers are not included in the SVD file for STM32H5, could you please advise on the best way to access or monitor SCB registers (e.g., VTOR, AIRCR, ICSR) during debugging in VS Code with PlatformIO? Specifically, I'm looking for guidance on: How to inspect SCB register values during a debug session (e.g., trap cause, exception entry). Recommended approach to capture trap/exception information like: HardFault status (HFSR) Configurable Fault Status (CFSR) Bus Fault (BFAR) MemManage Fault (MMFAR) Any suggestions for manual mapping or watch expressions in the debugger that would allow me to monitor these registers, since they’re not shown in the peripheral view. Any tips or best practices for bare-metal Cortex-M33 debugging without full SVD support would be greatly appreciated. Best regards,Manikanta 

Hello, I am trying to convert my Onnx model with the ST Edge AI Core tool to the .nb format for the STM32MP25 target.While converting the model i get the following error:ST Edge AI Core v2.2.0-20266 INTERNAL ERROR: unsupported operand type(s) for *: 'int' and 'shape_struct'I could track down the error to a resize operation in the Onnx model. Here is a short snippet how the model looks like:When i remove the resize operations and downscale the 28 x 28 patches to 14 x 14 patches. Then the error is gone.So i think that the resize operation is the problem. This happens for quantized and non quantized models. Like stated here (STM32MP2 NPU description - stm32mpu), there should be some resize operations implemented at least on the GPU. Did anyone had similar issues and know how to fix them?Thank you in advance for your help.Best regardsNils

I am working on STM32CubeIDE_2.1.0 after one week and suddenly it stopped showing create new STM32 Project. It is showing simply as in screenshot, I am unable to create new STM32 project. Thanks & RegardsChanchal

Are there any expansion boards with Quad SPI NOR Flash chips? I am interested in using it with a NUCLEO-WB55RG board.Preferably it should use the Macronix 25L6433FM2I-08G chip, but that is not a hard requirement. This chip is found on the X-NUCLEO-GFX01M2 board, but it is implemented as a standard single SPI interface.Thanks

Hi all,I’m working on porting a firmware from a Microchip PIC18F66J50 to an STM32C071.The original device communicates successfully with Windows and Android devices over USB, through an app developed in Flutter (Android Studio) using the QuickUsb library.On the STM32 side, I’m now using the USBX stack. After quite a bit of work, I managed to get the USB communication fully working with Windows — enumeration and protocol exchange both succeed.However, while the device correctly enumerates on Android, the protocol communication fails.Since the Android app already works perfectly with the original Microchip-based device, I assume that no changes are needed on the app side. This suggests that the issue lies in how the STM32 presents itself to Android (possibly in the USB descriptors or class/interface setup).Has anyone experienced similar issues with USBX on Android, or are there known differences in how Android handles vendor-specific protocols compared to Windows? Thanks for your he

Hello,I'm using the IMP34DT05 microphone and it records fine but there is always a noise overlapped and it is very annoying.I have tried recording the background noise in anechoic chamber (see attached audio, high-pass filter alpha is 0.98). Do you know I to get rid of this noise? Is it related to microphone self-noise? Is there some processing library available from ST to remove such noise?Could it be related to some issue with the pdm2pcm conversion? I’m using 24bits on 32 frame. The PDM2PCM filter gain is set to 30.Best,

I want to be able to program the external flash via VCP. So far, I have taken the combined code from the CM4 and CM7 core, then using memory address 0x90000000, I write to the QSPI using the BSP function: if (receiving_ext_flash) { if (BSP_QSPI_Write(0, Buf, qspi_write_address, Len) != BSP_ERROR_NONE) { CDC_Transmit_FS((uint8_t*)"QSPI Write Error\r\n", strlen("QSPI Write Error\r\n")); receiving_ext_flash = 0; return; } qspi_write_address += Len; } Has anyone tried doing something like this? I have not been able to get this to work. Thanks!

Is there any way to optimize the IPD BALFHB-WL-01D3 to work at 865MHz at 22dbm for STM32WL55? And is there any hardware design guide for power of STM32WL like it is there Hardware design guide for STM32L0 application note AN4467.

Trying to run timer2 to set pwm signal for the BLUE LED (PA5).The MCU is STM32U083MCT6 and I used rm for STM32U083MC series (https://www.st.com/resource/en/reference_manual/rm0503-stm32u0-series-advanced-armbased-32bit-mcus-stmicroelectronics.pdf)I set each bit and register separately to be sure that everything is set correctly, but still miss something related to TIM2.What settings to check related to TIM2 and what is the best approach to configure timers of this MCU?

I used stm32g030c8t6 ， I want to create the  External loader by stm32cubeIDE， but I don't understand how to create，Are there any operation instructions? flash：w25q64 ， interface is SPI-2

I all,I have a question regarding the EVSPIN32G4 board, specifically concerning the feedback resistors used in the current sensing network (default value: 11 kΩ).I am considering replacing them with 150 kΩ resistors. My main concern is whether this significant change will trigger the Overcurrent Protection (OCP) prematurely or cause stability issues with the internal op-amps.Has anyone experimented with such values, or are there specific hardware limitations I should be aware of?Best regards, Jules

Platform:SoC: STM32MP257Sensor: GC05A2 (5MP)Interface: CSI-2 Issue:I'm working on camera integration with GC05A2 on STM32MP257. The raw image quality is acceptable, but after enabling AWB and CCM in the ISP pipeline, the output image shows severe noise (both luminance and color noise), especially in low-light conditions (<300 Lux) or shadow areas.Questions:Where is the noise reduction? Does STM32MP257 ISP have built-in hardware noise reduction (2D/3D NR)? If yes, how do I enable and control it through V4L2 or the driver? 

Hello Everyone,I recently purchased STM32H7S78-DK.I'm looking for the code that runs on the discovery kit.As I understood from my collogue there should be an application that defines all the peripherals via cubeMX.I've downloaded the repository for this DK but all I see is examples that covers some of the peripherals and not one application that defines all the peripherals. I would if someone can share with the link for this application that define all the peripherals. 

Hi everyone,I am working on a custom board based on the STM32U575RGT6 (TrustZone enabled, FreeRTOS). I have successfully ported the SBSFU example originally provided for the B-U585I-IOT02A.My configuration is:MCUBOOT_APP_IMAGE_NUMBER = 1 (Single combined S and NS image)No external loader.To meet my application needs, I added a custom FLASH_STORAGE area at the end of the flash for EEPROM emulation. To do this cleanly, I modified flash_layout.h to dynamically compute the available FLASH_NS_PARTITION_SIZE based on the remaining space.The Problem: When I use MCUBOOT_OVERWRITE_ONLY, the OTA update (via Y-Modem) works perfectly. However, when I try to use the Swap mode (by commenting out #define MCUBOOT_OVERWRITE_ONLY), the firmware download succeeds, the board reboots, the bootloader validates the signature, starts the swap process, but then crashes with a status write fail:FWUPDATE --- Démarrage de la mi

Hello everyone, I’m working on the STM32G474RE and trying to generate two independent PWM outputs using the HRTIM peripheral. To get started, I followed this tutorial: wiki.st.com/stm32mcu/wiki/Getting_started_with_HRTIM For my first PWM output, I used: Timer: HRTIM1 Channel: CHA1 Compare Unit: CMP1 This one works perfectly , the duty cycle changes correctly when I update the compare value.   The problem When I tried to add a second PWM output, I followed the exact same steps as for the first one, except I used: Channel: CHC1 Compare Unit: still CMP1 (as shown in the tutorial) However, this second output (HRTIM1_CHC1) is always stuck at 50% duty cycle, no matter what compare value I write. Even if I set the compare value very low or very high, the output waveform stays at 0.5 duty cycle.   What I checked The GPIO pin for CHC1 is correctly configured in alternate function mode. The timer is enabled and running. The compare register is being updated (I

Split from: Evaluation of Encoder Signal Level Shifting Approach as that was a different issue, and has been solved.I am also working with this same issue, in my case i have a encoder operating at 24V, and signal in comparable frequency i have implemented a simple voltage divider, the circuit works just fine, but as i don't have equipment to measure the noise and also i would prefer to have galvanic separation to my MCU, so in this case is there any good suggested  level shifter or optocoupler, should i combine the both strategy of voltage divider and optocoupler or just 1 is fine (from perspective of noise and safety)?

Hello,I'm trying to get familiar with the STM32Cube extension for VSCode.I generated a basic STM32 project using STM32CubeMX, for my NUCLEO-H723ZG board.I then imported the generated cmake project using the extension tool, and configured it using the "setup STM32Cube project(s)" button of the extension, which created a launch.json file.When I try to run the debug config, I get the following error : bound doStepSettingsValidation Failed: Device not found: Error: Missing CMSIS_PACK_ROOTHere is the STM32Cube core output :025-10-20 16:19:33.002 [Info] Adding STM32Cube CLI path to environment: c:\Users\Jacques\.vscode\extensions\stmicroelectronics.stm32cube-ide-core-1.0.3\resources\binaries\win32\x86_64 2025-10-20 16:19:33.057 [Info] Configuring CMSIS_PACK_ROOT environment: C:\Users\Jacques\AppData\Local\stm32cube\packs 2025-10-20 16:19:33.099 [Info] Configuring CUBE_BUNDLE_PATH environment: C:\Users\Jacques\AppData\Local\stm32cube\bundles 2025-10-20 16:19:33.805 [Info] cube wrapper version

hi dear,I created a project by selecting CMake as the toolchain and ST-ARM-CLANG as the compiler using the STM32Cube extension for VS Code (3.7.0) on macOS. Attached below are my configuration settings.    The project builds successfully without any issues in the terminal. However, I am seeing the following error in the VS Code editor:"error: unknown argument: '--multi-lib-config=...'""message": "Unknown argument: '--multi-lib-config=/Users/myName/Library/Application Support/stm32cube/bundles/st-arm-clang-hybrid-19_1_6-description/0.0.6+st.1/etc/multilib.gnu_tools_for_stm32.yaml'",clang(drv_unknown_argument) Please let me know if there`s a solution for this. Thanks! Also, I would like to know how to enable float support for printf() in the CMake-based ST-ARM-CLANG environment.  

Dear ST Support Team,I am currently working with the STM32N657X0H3 microcontroller.We are attempting to use the internal 4.2 MB continuous SRAM (starting at address 0x34000000) as the framebuffer for LTDC.The procedure followed is:• Writing pixel data into internal SRAM at 0x34000000• Configuring LTDC_Layer1->CFBAR with the same framebuffer address• Enabling LTDC and RGB outputHowever, when using the internal SRAM (0x34000000) as the framebuffer, the RGB output signals remain inactive.When we configure the framebuffer in DTCM memory (as mentioned in the reference manual), the RGB signals become active and function as expected.However, the DTCM memory size is very small and not sufficient to hold a full framebuffer for our display resolution. Therefore, using DTCM is not a practical solution for our application.We have verified the following:• AXI read/write test passes successfully• Framebuffer base address is correctly configured• LTDC timing configuration is correct• RGB pin confi

 Hi ST Community,I’m working with STM32WBA (STM32WPAN / BlueNRG-style stack APIs). I’m using Extended Advertising on the peripheral (connectable + scannable, secondary PHY = Coded) and a STM32WBA central that scans and then calls aci_gap_create_connection().ProblemConnection is intermittent: sometimes it connects, but often the peripheral prints multiple times:HCI_DISCONNECTION_COMPLETE_EVT_CODE - Connection Handle: 0x01 - Reason: 0x3E (repeats 4–5 times)The central does retries very often, so the peripheral sees repeated disconnect events before it finally connects.Setup detailsPeripheral (Extended Advertising)Advertising set configured as connectable + scannable:u16Property = HCI_ADV_EVENT_PROP_CONNECTABLE | HCI_ADV_EVENT_PROP_SCANNABLE;Primary PHY = 1M, Secondary PHY = Coded (0x03):aci_gap_adv_set_configuration(..., primaryPHY=0x00, secondaryPHY=0x03, ...)Address type used in advertising set:u8AddressType = GAP_STATIC_RANDOM_ADDR;Advertising channels 37/38/39 enabledTX power se

Hello ST team,I am using Nucleo H753zi board, and I wanted to use X-CUBE-MEMSMIC1 expansion for sound source localization.I have already designed simple PCB to use MEMs microphone and connect it to H7 board's ADC. I want to understand how I can program my board to use 4 mics- GCC-PHAT algorithm to get location of sound source. I have gone through UM2212 and UM1901. Due to lack of experience in this field, can you guide me through how I can use this X-CUBE-MEMSMIC1 expansion for sound source localization? I found this diagram helpful and would like to understand how should I code to feed data from cache to Acoustic SL for processing.
