Summary  On a NUCLEO-N657X0-Q I have a custom (non-CubeMX-template) FSBL that copies an "LRUN" application image from external XSPI flash into AXISRAM and jumps to it. The byte-identical signed FSBL runs completely when I stage it with the debugger in Development boot (monitor reset → load → jump Reset_Handler) — the app runs end to end. But in true ROM flash-boot (BOOT pins set for boot-from-flash, power-cycle, no debugger), the FSBL reaches main() (user LEDs light) and then locks up before its first clock-configuration step. The lock-up is invisible to SWD, UART, and even fault handlers, which points at a processor LOCKUP tied to the state the boot ROM leaves at the FSBL entry in flash-boot (security / RIF / clock), which differs from the debugger path. I would like to understand what minimal init my FSBL must do at entry in flash-boot.  Hardware / tools  - Board: NUCLEO-N657X0-Q (MB1940), STM32N657X0H, Cortex-M55 + Neural-ART.

I am trying to adapt the QSPI Flash (QSPI_MemoryMapped) example found in the STM32WB5MM-DK to run with FreeRTOS. My hardware uses different ports for the QSPI connection but all has been set up through the ST32CubeMX program.What I did then was to copy the code from the example into my project as a FreeRTOS task. However, the code pulls in some header files that don’t make sense to me. For example: stm32wbxx_hal_tim_ex.h results in the error “unknown type name 'HAL_StatusTypeDef”I’m not sure why this is happening, or even why this header file is being pulled int, I so would appreciate any pointers. My guess is that is has to do the the HAL timer versus the FreeRTOS timer, but even then don’t know were to look!Since I am using the flash without a fie system, maybe the QSPI_ReadWrite_DMA or QSPI_ReadWrite_IT would be better. If so, please suggest...Thanks

Hi,At my company, we develop debuggers and are trying to access STM32MP257F-EV1(ES) board via the DAP,Unfortunately, we are unable to access the DAP and it seems like JTAG (DAP) access is prohibited by hardware.The result was the same even after shorting JP3 and turning off ST-LINK.I have the following questions:Are there any other jumpers positions that have to be changed? Please let me know.Does STM32MP257F-EV1(ES) have debug authentication enabled by default?If so, please let me know if there are any technical documents that explain the procedure for debug authentication.I tried to connect to the on-board debugger by running STM32CubeProgrammer and choosing ST-LINK (SWD), but access was denied.The boot mode that I tried were "UART/USB" and "Development", but both showed the following error:Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug AuthenticationPlease let me know if there is a document or URL that explains how S

Hi team,we have custom project based on STM32U558 controller with TrustZone, and I am only involved in small part of the project.but i would like to learn about this trust zone is enabled and how both secure and non secure zone are talking.how i will identify which peripheral and which pins are intialised as secure and non secure part.also will appreciate if provided with reading section for trustzone.(prefer small blogs, not big one just because i am a new to trust zone).

Board: STM32N6 (Custom board with USB OTG HS)I am trying to create a USB composite device with:  - CDC ACM Instance 0 (LOG port) - Interfaces 0, 1  - CDC ACM Instance 1 (DATA port for GenICam/GenCP) - Interfaces 2, 3  - UVC VIDEO class - Interfaces 4, 5Dual CDC works perfectly.

Hello, I am new to high speed layout and am just learning a new layout tool so the pressure is on. What I need is some layout examples I can study to boost my chances of getting it right. Can anyone help please?

Hello,I’m working with a project with STM32h563 micro which includes the use of the OEMiROT bootloader. I tried different solution to set up the project, and, in order to use CubeMX, I think this is the “normal” way. However, there are some things that look awkward to me.If you want to use the OEMiROT bootloader included in the firmware package mentioned in the tutorial, it seems to be mandatory to strictly respect the folder tree given used inside the package. This means that your application project has to reside in STM32Cube_FW_H5_V1.6.0/Projects/NUCLEO-H563ZI/Applications/ROT/ even if you are not using a NUCLEO board. When, in CubeMX, you set the Boot Path and Debug Authentication options, you can modify the OEM_iROT reference location but not the Config Files Location, which is mandatory to be inside the ROT_Provisioning folder automatically created inside the newly created application (e.g. STM32Cube_FW_H5_V1.6.0/Projects/NUCLEO-H563ZI/Applications/ROT/ROT_Provisioning). However,

Hello,I was trying to run AC1 and ADC2 in Dual mode and ADC3 configured as independent one.Using HAL_ADC_Start for ADC3 doesn’t start the converter as it checks multi-mode in common ADC_CCR register wrongly not allowing to use ADC3 for ADC_DUALMODE_REGSIMULT (value 6). I prepared a patch for stm32f4xx_hal_adc.c, but not for injected channels from stm32f4xx_hal_adc_ex.c file as they have a similar issue.Could it be checked by library owner or someone responsible for the code? Firmware Package Name and Version : STM32Cube FW_F4 V1.28.3STM32CubeMX 6.14.0MCU STM32F446ZEJx Best RegardsJarosław Hill

Hello,I am redesigning a circuit that uses the comparator LM2903YPT, because the previous circuit had an undefined output because of the inputs that were outside the common mode range.According to the datasheet the input common mode range for my application is between -5V53 to -2V, considering also the entire operating temperature range.I expected that the output should change between Vol and Voh, where Voh is similar to Vcc+ and Vol is -5V5+0.25V=-5V25.As I can see in the simulation the output changes between  ~0V and -304mV. The inputs are now inside of the common mode range.Could you hep me please to understand the behavior of the comparator? Or if there is any issue in my circuit? Thank you in advance!

While fiddling with H745 board to investigate how dual core works, after modifying option byte to BOOT_CM7 = 0 and BOOT_CM4, STM32CubeProgrammer (nor STLINK-gdbserver) refuses to connect to the board with "Error: No STM32 target found". The ST-Link itself is okay. Here is a log from the programmer.22:31:39 : ST-LINK SN : 002F003D3137510E39383538 22:31:39 : ST-LINK FW : V3J5M2 22:31:39 : Voltage : 3.30V 22:31:39 : No STM32 target found! 22:31:39 : ST-LINK SN : 002F003D3137510E39383538 22:31:39 : ST-LINK FW : V3J5M2 22:31:39 : Voltage : 3.30V 22:31:39 : Error: No STM32 target found!How do I regain access to the board?

Hello,We are designing a custom board using the STM32MP157FAC1 device. For programming and debugging, we are planning to provide an STDC14 connector on our board and use the STLINK-V3SET debugger/programmer.We have the following queries:(1.) Is the STLINK-V3SET suitable for programming and debugging the STM32MP157FAC1 device?(2.) We have connected T_VCP_TX (Virtual COM Port transmit signal) to PG11, which can be configured as UART4_TX, and T_VCP_RX (Virtual COM Port receive signal) to PB2, which can be configured as UART4_RX on the STM32MP157. Kindly confirm whether this connection scheme is correct.(3.) The SWD and Virtual COM UART signals are connected directly from the STDC14 connector to the STM32MP157FAC1 device. Is any ESD protection recommended on these signals? If yes, kindly share the relevant reference.Regards,Prashant Sharma

Hello everyone,I am looking for some help getting started with the STSAFE-A110 in a new project.My Setup: MCU: Custom board using STM32H503CBT6 Secure Element: X-NUCLEO-SAFEA1B expansion board Software: STM32CubeIDE with the X-CUBE-SAFEA1 middleware added via CubeMX Output: I am using the USB CDC Virtual COM port (Classic Middleware) for my output. I have not enabled and am not using UART. The Problem:I am completely stuck trying to get the initial communication working. I cannot seem to establish communication between the STM32H5 and the STSAFE-A110 through I2C, and I cannot get StSafeA_Init() to initialize the STSAFE properly.I have tried reading the user manual (UM2646 - Getting started with the X-CUBE-SAFEA1), but I find it extremely confusing. It does not clearly outline the necessary steps that I need to take to start the project properly from code generated by CubeMX.What I need help with:Could someone provide a clear, step-by-step guide on how to actually bring up the STS

This is a small feature request to fix an annoying quirk of the TouchGFX Designer.When opening the texts menu in the designer, all of the texts groups are expanded by default. In projects with many texts/groups, its tedious to collapse all of the groups or scroll to the bottom of the expanded groups. I think it would be better if either TGFX stored the state of the groups expansion OR collapsed them all by default.

When sending the first initial SYNC (0x7F) byte to the STM32N6 boot ROM over UART, the boot ROM replies with two ACK (0x79) bytes, while only one ACK is sent as a response to later SYNCs. Is the boot ROM guaranteed to always reply with two ACKs to the first SYNC?First sync:Later syncs:

Hi there,Im trying to get my STEVAL-PTOOL1V1 up and running with my motor, a Sofasco sDBS7025 with the following specs:3-phase BLDC7-12V DC operating voltage1.5A rated current11100 max RPM 4 pole 8 pins:PinFunction1V2W3U4HW5HU6HV75V08COMI have managed to get it operating by using the STEVAL-PTOOL1V1_6S_HL example project in the ST Motor Control SDK V 6.4.1 however I seem to have little control over the speed.I haven't been using the potentiometer feature of the STEVAL-PTOOL1V1 and instead been using the following functions:MC_ProgramSpeedRampMotor1(2000, 1000);MC_StartMotor1();and when wanting to change the speed, changing the 2000 for a different speed and rebuilding the project and programming to the board.However when I input a different speed e.g. 10000 there is no difference to the speed, observed by the current draw of the bench power supply remaining the same. I suspect I have setup the motor parameters incorrectly in the MC Workbench 6-step wizard but am not

The STM32G031G8U6 in a UFQFPN28 package does not have PF0 / PF1 pins for HSE OSC_IN / OSC_OUT.  It does however have OSC_IN on PC14.  This is intended for an external CMOS oscillator in bypass mode.I’m currently in the schematic design stage. My board clock is a clipped-sine TCXO used for other purposes.  In some modes, I’d like to use it to clock the STM32. I’m very constrained on cost, power, and board space.  The clipped-sine doesn't meet the voltage level requirements for a bypass-mode clock.Is it possible to configure HSE as if it were a crystal, but instead supply a clipped-sine 0.8 Vpp clock from the TCXO to PC14 OSC_IN? Does the die used in UFQFPN28 even have the HSE oscillator circuit that exists in the 48 pin package?I would set RCC_CR[HSEBYP] = 0 and RCC_CR[HSEON] = 1.  I don’t see any register controlling the OSC_IN alternate function on PC14.  STM32CubeIDE doesn't allow this configuration, unsurprisingly, but I would configure t

Using the new VSC Integrations, when I add a new .h/.c file to and STM32 project, do I really have to manually update the CMakeLists.txt file too? This seems like a retrograde step. If I just right-click on the SRC or INC folder and add a new file, I get lots of include errors etc, because (I think) CMake is not aware of these files.AI Told me to try out two extensions, but it was either hallucinating, or they are not available for VSC on macOS.They were CMake File Helper and/or C/C++ File Creator.What is the best/suggested way of adding new files to a project?

Hello ST Community,I am using STM32H7B3 + TouchGFX + 7-inch 800×480 TFT with GT911/GT9111 touch controller.In the TouchGFX PC simulator, all buttons and toggle switches work correctly. But after flashing to hardware:TFT display is working properly.Touch is detected.Actual touch point and detected touch point are different.Touch is detected on the same horizontal line, but the vertical coordinate is shifted/wrong.I want to know the correct solution for touch coordinate mapping/calibration. Should this correction be done. Please guide me on the correct method for touch calibration and hardware control/status display in TouchGFX.Thank you.

Hiwe are using IC: STN3NF06L in our design.Please provide Mtbf & Fit Data for the ic.Thank you. 

On the STM32C542CC in LQFP48, none of the Port C pins that support I2S MCLK output are available. Despite this, enabling the "Master Clock Output" under "Advanced Features" in the MX2 Peripherals tab is still possible and reports no warnings or errors.

Hi all,I want to design STM32N6 based board and in this board I don’t have any 3.3V supply so what should I do the unused USB power pins? Should I left unconnected or connect them to GND? Thanks and regards

Hello, I hope all is well. I’m also looking for the FCC test report for the STM32WLE5CCU6. I noticed someone else had requested it previously, but the inquiry seemed to be redirected and may not have been followed through. In short, I will need someone from your compliance or technical team to contact me directly via email. We are currently working on the FCC frequency‑hopping requirements, and I’d like to understand how this was handled on your side and hopefully obtain some manufacturer guidance. Thank you in advance.
