A customer asked for the process technology or process node in nano meters (nm) for the STM32F303CCT7 we use. I can not find any information on ST website. The “Sidekick” told me there is no information about. Can someone help me?

Hi,I am using LSM6DSV320X for my project. Initially to save power I have Low G accelerometer with 15Hz ODR and 16G with fifo enabled. Once an activity is detected i want to switch on High G as well with 4000 Hz (with High Accuracy mode) and use both high G and Low G accelerometer for data collection. Is this possible if I dont use FSM or ASC and will High Accuracy then work ?. or can this only be achieved with FSM ? I look forward to your reply.

Hello,I am using the Nucleo STM32H533RE board for booting with the two stage boot path for which I am using the ST template code and referring the following   https://wiki.st.com/stm32mcu/wiki/Security:OEMiRoT_OEMuRoT_for_STM32H7S . I am able to run the provisioning script successfully but when I am connecting the serial terminal to verify the serial data sent out by the board, I am getting an error saying “[ERR] read:Wrong OBK HDPL2 cfg” as seen in below image:I tried with the following things:Regenerating the OEMuROT OBK files manually using stm32 trusted package creator Running the regression script to erase the flash and again running the provisioning script Verified if the key file names matches the script referencesCan someone help me with this issue.Let me know if any other details are required. Thanks,Amruta

Hello,I am working with an STM32N6570-DK board and facing an issue while setting up the SD card. I created a project using TouchGFX Designer, generated the code, and opened the .ioc file. In there, I enabled SDMMC2 with 4-bit Wide mode and enabled global interrupt:After checking the schematics, I noticed that the CK pin was incorrect, so I assigned the correct pin (PC2:(I made the following additional configurations:Changed all SDMMC2 pins to pull-up and set Max output speed to Very HighEnabled PWR_SD_EN (PQ7) as output level high with context FreeChanged clock from HCLK to IC4 (should not affect anything)Enabled SD_DETECT (PN12) to detect when the SD card is inserted or removedEnabled EXTI Line4 and EXTI Line12 for interruptsEnabled FileX with mostly default settings, except for increased memory and FX driver initialization:After this setup, I attempted to initialize the SD card with the following call:fx_media_open(&sdio_disk, "SDIO_DISK", fx_stm32_sd_driver, NULL, fx_sd_media_me

I'm trying to configure and generate a project with STM32CubeMX for the STM32WBA5MMGHx BLE module.When enabling the STM32_WPAN middleware, the ADV_TRACE module gets automatically enabled under Utilities. This in turn requires to enable at least one UART/LPUART peripheral, otherwise type UART_HandleTypeDef is undefined and compiler throws and error:../../Core/Inc/app_conf.h:304:8: error: unknown type name 'UART_HandleTypeDef'; did you mean 'RTC_HandleTypeDef'? [build] 304 | extern UART_HandleTypeDef huart1; [build] | ^~~~~~~~~~~~~~~~~~ [build] | RTC_HandleTypeDefThe STM32_WPAN throws a warning about not configured/wrong Platform Settings.Is there any possibility to configure STM32_WPAN without ADV_TRACE enabled?Used STM32CubeMX version is 6.17.0 and WBA firmware v1.19.0 and cmake project is generated.

Board: STEVAL-MKI109D (STM32H563ZI) + STEVAL-MKI207V1 adapter (ISM330DHCX)Goal: Bare-metal custom firmware reading WHO_AM_I over SPI1Following up on my earlier thread about GPIO pin mapping [link to old thread] — pin mapping is now resolved (SPI1_NSS on PA15, confirmed via community input; PA4/PA5 are DAC1 Vdd_set/VddIO_set as discussed). Thanks for the help getting there.I'm now stuck on a different issue and would appreciate a sanity check. WHO_AM_I consistently reads 0xFF, but every layer I can verify from firmware/multimeter checks out correctly:CS on PA15 (GPIO output, confirmed via MODER/ODR register dump) SPI1 Mode 3 (CPOL=1, CPHA=1) — confirmed via CFG2 register decode SCK/MISO/MOSI on PB3/PB4/PB5, AF5 — confirmed via GPIOB MODER/AFRL dump VDD/VDDIO measured 3.3V at the DIL24 breakout header (J13/J14 area on JP1/JP2), in spec HAL_SPI_TransmitReceive returns HAL_OK, ErrorCode=0x0, every call — no timeout, no fault Tested at both SPI_BAUDRATEPRESCALER_32 and _256 (extremes) — ide

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,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:

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

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?
