Device Under Test: PXN V9 Gen2 Steering Wheel (operating in native D-Input mode) Hardware Platform: STM32F446RE Nucleo Board acting as a USB Host. Toolchain: STM32CubeIDE. Driver Framework: Custom embedded USB Host HID stack implemented by extending and adapting the native usbh_hid.c library provided by the STM32Cube firmware package. Analysis Tools: Wireshark with a USBPcap I am attempting to initialize a force feedback (rumble) effect sequence from the STM32 host. According to the USB PID specification, the transaction sequence rules: Send Create New Effect Report (Report ID 0x05) via a Control Out transfer. Read PID Block Load Report (Report ID 0x06) via a Control In transfer to retrieve the allocated Effect Block Index. The Symptom: When performing the Control In transfer to fetch Report ID 0x06, the data payload returned to the STM32 memory buffer is entirely filled with 0x00 bytes instead of a valid allocation status or a non-zero block index handle. No asynchronous data

Hi guys, I’m using lwip libray with netconn api on stm32h7, I want to enable the receive timeout using netconn_set_recvtimeout method. In order to do that LWIP_SO_RECVTIMEO macro should be set to 1 (default value is 0). There is no LWIP_SO_RECVTIMEO macro in the LWIP section of the .ioc file.How can I configure it ? Shoudl I set another macro in the .ioc or should I change LWIP_SO_RECVTIMEO value in the header file ? 

Hi, I’m looking into the WL55JC1 for a project which would require the system to remain dormant (ideally standby) for weeks, maybe months and then resume operation on a set date at a set time. I would like to use LSI as power and space will be very limited.So far I’ve discovered, that of course there is an RTC and it has alarms that can be used to wake from standby mode. However all examples and documentation I can find only ever use times or maybe day-of-week or day-of-month as the set wake up time. Never a full date and time. Looking at the code, stm32wlxx_hal_rtc.h defines a struct RTC_AlarmTypeDef with fields for seconds, minutes, hours and either a day-of-month, or day-of-week.Is it really not possible to give the system a full a date and time yyyy-mm-dd and hh-mm to wake up at? Will I need to build workaround waking up at least once a month to recalculate the next wake-up until the actual target time is within the same calendar month?Or am I overlooking something?I’d appreciate a

Hello everyone, I can run my model through the stedgeai / STM32Cube AI Studio and see the following: But when I now go into the resulting application and build it myself, I see these memory sections, which tell a totally different story: How can I fix this? I added the AXISRAMx sections (they are not provided per default) which results in them being used by 0%, so that also can’t be right. Best regards, rphii

why while creating new project in stm32cubemx, it  show like this error downloading the following files crdb.zip?download has failed ,some data may not be updated,please retry later. how to solve it?

custom board, The USB D+ and D− lines are connected directly from the MCU to the USB Type-B connector, with no intermediate components. There is no pull-up resistor on the D+ line, as I understand that the MCU provides the pull-up internallyAs far as I know, the stm32u595 supports USB High-Speed using its internal PHY.CubeMX Version: 6.18.0Reference project:https://github.com/STMicroelectronics/STM32CubeU5/tree/main/Projects/STM32U5G9J-DK2/Applications/USBX/Ux_Device_CDC_ACMI configured my .ioc file to match the reference project as closely as possible. UART is not used.Issue:I implemented a simple CDC ACM echo function to verify USB communication.In Full-Speed (FS) mode, the echo function works correctly. The PC recognizes the device, and both transmit and receive operate normally. In High-Speed (HS) mode, however, the PC does not recognize the USB device at all (it reports an unknown or unrecognized USB device), so communication cannot be established.What could I be missing, or what

Hello,I dont understand in the AN4776, page 66 the following: /****** Master mode configuration: Trigger update mode *******/ /* Trigger of TIM2 Update into TIM1 Slave */TIM1->CR2 &= ~ TIM_CR2_MMS;TIM2->CR2 |= TIM_TRGO_UPDATE; why TIM1? there should have to mask the TIM2 master settings, before setting TRGO update, or i mistake? Moreover the TIM1 have been already set and active.

Hi all, i am just trying to figure out how to connect the Stwinbox board with Rs485. if you have any advice in terms of applications i must use and the recommended firmware?  regards

I have followed the following guide step by step (Except using the NUCLEO-H755ZI-Q board which I have): I have copied the exact launch.json used in the guide, as well as ran the Project Setup as described in the guide. I also selected “DualCore_Debug” as debug configuration. When I start to debug the code the following error occurs pretty much instantly:bound doStepSettingsValidation Failed: Device not found: run "Setup STM32Cube project(s)" command or set "deviceName"attributeWhen clicking any of the two buttons the same error pops up a second time, I suspect that’s because of the two cores, but that’s only a guess.When connecting the NUCLEO-board it is being detected by the operating system and is also listed under “STM32CUBE DEVICES AND BOARDS”:NUCLEO-Board being detected by VS Code/STM32CubeIDEWhen I re-run the Project setup I see the Projects correctly assigned to each core, although for the M7 another project has been automatically added, which I did not add myself:Porjects being

Hi ST Team,I am trying to enable Bluetooth LE Privacy (Resolvable Private Address) on an STM32WB55CG.EnvironmentMCU: STM32WB55CG STM32CubeWB Package: v1.23.0 BLE Stack: v1.23.0.3 FUS: v1.2.0.0What I changedI changed the address type from: #define CFG_BLE_ADDRESS_TYPE PUBLIC_ADDRto #define CFG_BLE_ADDRESS_TYPE RESOLVABLE_PRIVATE_ADDRThe generated code calls: aci_gap_init( role, 2, ...);and aci_gap_set_discoverable( ... RESOLVABLE_PRIVATE_ADDR, ...);Initially, aci_gap_set_authentication_requirement() was also using CFG_BLE_ADDRESS_TYPE as the Identity Address Type. I found an ST forum discussion mentioning this is incorrect, so I changed it to: aci_gap_set_authentication_requirement( ... PUBLIC_ADDR);However, the behavior did not change.Observed behaviorWith CFG_BLE_ADDRESS_TYPE = PUBLIC_ADDRPairing succeeds. Device works normally.With CFG_BLE_ADDRESS_TYPE = RESOLVABLE_PRIVATE_ADDRConnection is established. Pairing fails. ACI_GAP_PAIRING_COMPLETE_VSEVT_CODE

Dear team, hello, I've drawn a power supply circuit diagram for the STM32F051R8T6 but I'm a little hesitant. The diagram of my circuit is below. Have I done it correctly? Thank you for your answer. 

Hello, I have an STM32H573 project with TrustZone enabled. After the CPU goes into non-secure mode and during execution of the HAL_Init() function (more specifics below) a hard fault occurs. There is only a hard fault during the execution from a non-secure state. In the secure state (at boot) the HAL_Init() function successfully runs. Is there a configuration for the RCC not enabled by default that I a missing, allowing it to be accessed by both Secure and Non-Secure CPU states?Within GTZC_S TZSC - Privilegeable peripherals I cannot enable it. I see no relevant settings (I have tested a few that might be loosely related but no solved) in RCC. In the code below I have used an arrow (<--) to denote exactly where the hard fault occurs (Verified with debugger)Non-Secure Entry Code (CubeMX Generated):int main(void){ /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ /* MCU Configuration--------------------------------------------------------*/ /* MPU Configuration-------------------------

Hi team,I am working on a firmware upgrade implementation using the ST25DV04KC NFC tag in FTM (Fast Transfer Mode).I have successfully ported the ST25FTM library to my target microcontroller. Basic commands and demos—such as checking the board version and sending passwords—work consistently.However, I am experiencing a severe reliability issue with the actual Firmware Upgrade process. The upgrade fails roughly 90% of the time. It only succeeds occasionally (~10% success rate). The target 8 Bit PIC18 microcontroller.I have attached the console log of a failed session below for reference. Could you please help me identify what might be causing these frequent failures, or let me know if you need any additional logs or hardware details from my side? Thanks.Console Logs:Jul 09, 2026 8:49:50 AM com.st.st25sdk.STLog i INFO: mState = PREPARE_PACKET Jul 09, 2026 8:49:50 AM com.st.st25sdk.STLog i INFO: sendNextPacket Jul 09, 2026 8:49:50 AM com.st.st25sdk.STLog i INFO: preparePacket Jul 09, 2026

I am using STM32MP157C with kernel version 6.6, and the problem I am currently experiencing is that HDMI cannot display. The hardware design uses SII9022ACNU chip, and the driver keeps reporting probe failure with a return value of -11. The SII9022 HDMI chip does not respond to I2C communication on the 6.6 kernel, and manually resetting GPIO is also ineffective. Have you encountered similar problems and how have they been resolved。

Hi everyone,I'm using STM32 Cube Programmer CLI to port an SBSFU example to STM32U5G9 platform (from U585). Other than shell script mess and no IOC files in this examples, I've managed to port the example and run it by using ST Link programmer under both Linux and Windows.The problem is that the newest release 2.20 has its J-Link functionality completely broken in Linux (I'm using Kubuntu 22.04 and 24.04, also tested in regular Ubuntu). Any command to STM32_cube_programmer_CLI ends up with:Error: Could not connect to the J-Link/Flasher, Library not found !The underlying issue is that libjlinkarm.so is not linked to the CLI executable: ldd shows it's linked for older versions, but no linkage for v2.20. I'm guessing this has happened since ST was finally moving away from weird versioned so names to non-versioned so's: i.e. libjlinkarm.so.7 -> libjlinkarm.soI'm hoping that someone from ST will read this message since the issue is not possible to resolve without re-linking... So @s

Hi everyone,I am new to the MCSDK environment and currently working on a porting project from MCSDK 5.4.8 to 6.4.1. I have been stuck on this for weeks and I am honestly getting desperate as I cannot find a way forward.I need a functional routine to handle encoder alignment that is compatible with the 6.4.1 framework. The alignment must be performed solely upon user request, and it is critical that the motor does not start running after the alignment sequence. I am looking for a direct replacement for the legacy MCAlignEncoderMotor1() API.I have already attempted the implementation suggested in this thread: MCSDK 6.3 - Correct way to restart / retrigger encoder alignmentUnfortunately, this solution does not work for my setup. Could you please provide guidance on how to trigger this alignment in isolation within the 6.4.1 architecture?Best regards,bolla_bo
