I would like to confirm whether the Ethernet MAC available in the STM32N655x0H3Q supports 1000 Mbps (Gigabit Ethernet) operation.

Part is ~10-20 years old. Found some vague info that says there is an STM part# 35AX. Package is 14 pin, 14-VFLGA/LGA (3mm x 5mm). Pretty sure its an IMU/Accelerometer but trying to track down a pinout for a possible replacement.

Hi everyone,I am using the STGAP3SXS isolated gate driver on my custom PCB, but I am unable to get it to operate correctly.I have attached my schematic for reference.I tested the driver in two different configurations:With all protection circuits enabled (DESAT, Miller clamp, etc.) With the protection circuitry removed/disabled (minimal configuration)In both cases, the behavior is exactly the same.ObservationsPin 13 (DIAG) remains HIGH. Pin 14 (RST) also remains HIGH. No gate output is generated.According to the datasheet, DIAG is the diagnostic output and RST is the active-low reset/shutdown input. I expected the device to operate normally when RST is kept HIGH, but the driver never starts.I have verified:Logic supply (VDD) Isolated gate supply (VH/VL) Input signals (IN+ and IN−) PCB connections and solderingHowever, the behaviour remains unchanged in both hardware versions.Could someone please review the attached schematic and let me know if there is anything obviously incorrect or i

Is it possible to measure power consumption using software such as CubeMonitor-power with the NUCLEO-U031R8?I know there are ways to measure JP5 using a tester, but I'd like to measure it using software. Is this possible?

Hi,I wish to buy this evaluation board:EVAL6470PD | Product - STMicroelectronics However, it's flagged as obsolete. Does this mean that POWERSO36 package of L6470 is not recommended for new design?Many thanks.WH

Hello, I am encountering an issue when connecting an ST‑Link with no target attached. On the first connection attempt it reports “No STM32 target found.” If I attempt to connect a second time, the adapter returns the error “ST‑LINK error (DEV_USB_COMM_ERR).” The only reliable recovery I have found is to unplug and replug the USB device:ST-LINK with DEV_USB_COMM_ERR issue When I use a different ST‑Link from the same batch (B 2022 48) with the same firmware, it behaves as expected and reports “No STM32 target found” until a target is present:ST-LINK without the issue Environment and reproduction steps:- Software: STM32CubeProgrammer CLI and GUI v2.23.0 (issue also reproducible with v2.22.0)- Commands (basically any -c): STM32_Programmer_CLI -c port=swd index=0 freq=4000 mode=ur -w "<Firmware path>" -v --start 0x8000000STM32_Programmer_CLI -c port=swd- OS: Windows 11- USB: Direct connection to PC- Cable: Same behavior with a Tag‑Connect or no target cable attached- ST‑Link firmware:

I can build it successfully using west but when I program it I get: "Warning: The core is locked up" and no LED blinks. I also made my own blinking LED but that doesn't work either. I can program the board using stmcubeide and that work. It seems to be an stm32cubeprogrammer issue?

Hi ST community,We are evaluating motor-control architecture for a 3-phase BLDC/PMSM ESC project based on STM32G431 / STSPIN32G4.Currently we understand that STM32 MCSDK supports both:- FOC control projects- 6-step / trapezoidal control projectsHowever, we would like to clarify whether MCSDK officially supports runtime switch-over from 6-step control to FOC control in the same firmware project.Our target concept is:1. Start the motor with 6-step control or open-loop 6-step startup.2. After the motor reaches a sufficient speed / stable rotor position estimation, switch to FOC control.3. Continue running with FOC current loop and SVPWM.Questions:1. Does MCSDK officially support runtime switch-over from 6-step control to FOC control in one generated project?2. If not officially supported, is there any ST reference implementation, application note, or recommended method for implementing this handover?3. Can MCSDK-generated 6-step and FOC control modules coexist in one runtime while sharing

I have been trying to download STM32CubeIDE for Windows, but the download never starts. Someone can help me with this issue?

Hi,I wanted to give Visual Studio Code a try and converted an existing STM32CubeIDE project. In the original project, the main.c (in Core/Src directory) file was compiled using g++, since it has some C++ content. However, VS Code invokes gcc, and therefore, build is not successful. How can I change this?One other thing, I noticed when converting the project, all source files are copied to the new location, but the .ioc file is not. Is this intended behaviour?

I started with the MC workbench and installed X-Cube-MCSDK Version 6.4.2. After installation the MC Workbench is opened, but the dialog is complete empty (except the caption). The behaviour is the same if i start the workbench via the desktop icon or as administrator.

Are there any Dual Core LoRaWAN Application examples for the STM32WL55CC that use the STM32Cube FW WL V1.5.0 (LBM) libraries?  If  there aren’t, will this be supported in the future? Thanks,Nick

Am using Engine Control eTPU Library (AN4907SW) in the SPC563M64L5 device.And in the source files, there is a piece of code which needs to be enabled for MPC5500 devices as it is mentioned in the comment that “an errata 2477 is present on MPC5500 devices”. Since SPC563M64L5 device is almost similar to MPC5634M device which is MPC5500 family as both jointly developed. does these errata applicable to SPC563M64L5 as well?

i've just installed all necessary requirements for the STM32 vscode extension however it doesn't seem to launch cube mx or mcu finder when i click launch from vscode. not sure if its incorrect paths or permission issues?please see the screenshot for the path settings

I’ve started from the LWIP TCP echo server with FreeRTOS example from ST and have made a *.ioc2 file to support that example. The issue is that I’m starting from the NUCLEO-C5A3ZG (which I’ve configured the *.ioc2 project), but intend to use a STM32C593 in my final product. My understanding was that STM32CubeMX would allow switching microcontrollers, but keeping the similar configuration settings (e.g. LWIP, FreeRTOS, etc.). I’d like to have the project required configuration settings managed in a tool like CubeMX2, but this will not be possible/feasible if I can’t make changes without having to start completely from scratch every time we make a change. Is there a setting somewhere that I’ve missed to allow switching processors? Is this a planned feature that may not yet be released? Thanks in advance.

Hi,We are using the ST25R3920B NFC reader IC along with the NXP S32K312 MCU running an AUTOSAR OS for NFC card detection.We have observed that, after the NFC wake-up event, the NFC initialization and polling sequence takes approximately 300 ms before a card is detected. This startup time is longer than expected and is impacting our application requirements.Could you please suggest any configuration changes, RFAL optimizations, or best practices to reduce the NFC initialization and polling time? If there are any recommended settings for use with an AUTOSAR-based system or the ST25R3920B that can help improve startup performance, we would greatly appreciate your guidance.Thanks,Anitha

Dear ST Support Team,I am using the STM32MP157F-DK2 evaluation board with OpenSTLinux (Linux kernel 5.15).I am interfacing a Telit LE910C1-IN LTE modem through the USB Host interface. The modem is successfully detected by lsusb (VID:PID 1bc7:1201), and dmesg confirms successful USB enumeration. However, no /dev/ttyUSB* devices are created, preventing AT command communication.I also verified that the kernel configuration shows:# CONFIG_USB_SERIAL is not setCould you please provide the recommended procedure to enable USB modem support for the Telit LE910 on STM32MP157F-DK2? Specifically, I would like to know the required kernel configuration, drivers, packages, or any additional Device Tree or software changes needed to create the /dev/ttyUSB* interfaces.Below is relevant screenshot for reference.Thank you.

 Dear STMicroelectronics Support,In our application, the STM32H7B3I-DK board is used in a "shield" configuration: it is mounted on a carrier/daughter board(PHOTO 2) (via the Arduino connectors CN19/CN20/CN10/CN11) which supplies its power. The daughter board therefore injects a 5V voltage directly onto CN19, pin 1 (5V_VIN), without going through a USB supply or through the standard VIN input of the kit.Power configuration5 V is applied to CN19, pin 1 (5V_VIN). JP1 is configured in the 5V_VIN position. VIN (CN19, pin 8) is left unconnected.MeasurementsVoltage before R114 (1 kΩ): 5.0 V Voltage after R114: 1.6 VThis corresponds to a voltage drop of approximately 3.4 V across R114, which indicates a current of about 3.4 mA flowing through the resistor.I would like to better understand whether this behavior is expected and the purpose of R114 in this circuit.Could you please clarify the following points?Is this voltage drop across R114 normal when powering the board through 5V_VIN?
