Split from this thread for a new question. Thank you. I've changed the programmer, and it now programmed without errors. I however get a Hard Fault, sitting in HardFault_Handler(), as soon as I run. It happens before the code gets to main(). It also does not look like it is matching symbols to files correctly, because it is not showing code. I did check that Load Symbols is checked in debugger settings. Can this HardFault be related, or should I start new post to help with that?

I have been using Scool together with Keil for years, but last tuesday after I started my PC and a win11 update was installed, I started Scool but got this error: "The PC/SC access cannot be enabled for the reader (driver not installed?) SdtReaderDllLoader Function name:ENABLE_PCSC_ACCESSParameter 1:SCtool Virtual Reader" When trying to update driver in Device Manager, I get code 31. (Well known win error code it seems, and I've tried all sugested solutions from AI and others without success.)My HW card readers also failed, but I managed to find and install newer drivers for them from the internet, so they are running again, only Virtual SCtool drivers I can't find, so the question is, are there any new win11 drivers for SCtool? (My present SCtool Virtual Driver is version 1.1.0.0) Helpdesk sugested I tried to install Scool on a new PC win11 25H2, and drivers worked fine on that. (My present PC is version win11 23H2, and my collegue has exact same PC and win version, where dr

Post moved from this thread. @ STTwo-32 I am using the same STM32H755ZIQ board and facing the same issue where the target is not detected by ST-Link after uploading the program.This is the code link: https://github.com/kavyammengineer/stm32debug/tree/main/led_on_offThe code works correctly on the Nucleo-H755ZIQ board, but when I upload it to my customized board, the target gets stuck and is no longer detected by ST-Link.this is my sysclk 64Mhz 

Hi,Since we haven’t received the datasheet yet, we’d like to confirm the following information:If the receiver side (RX) uses the STWLC89 15 W solution, what is the corresponding 15 W transmitter (TX) model?Which Qi standards are supported by STWLC89? (Qi 2.1 or ....)

Hello everyone,MCU in use: STM32H745XI (dual-core, Bootloader v9.1, CubeIDE 1.16.1, HAL v1.11.3, CubeProgrammer v2.17.0)Hardware status: BOOT0 HIGH works perfectly, I can access the system bootloader over USART1 (PA9/PA10), and program via UART. Hardware is validated and all connections are good. PB15/PB14 pins are floating, not connected anywhere.My need:I want to jump from user application (C code only, no BOOT0 pin) to the internal ROM system bootloader for firmware update purposes, so that I can upload new firmware over UART (using CubeProgrammer or similar), and then return to normal application on the next reset.Here are the methods I have tried (none worked):Set MSP to 0x1FF09800, jump to 0x1FF09804 (function pointer), disable all interrupts (NVIC->ICER), set PRIMASK/FAULTMASK, disable and invalidate caches (SCB), disable SysTick, deinit all peripherals (HAL_DeInit, RCC_DeInit, etc.).Disable MPU/SAU regions (including secure/privileged regions).Put all GPIOs (including used U

Title edited to correct part number: it is a Geehy APM32F103CBT6 - not an STM32.See this post.Hi everyone,I am working on a project using the STM32F103CB MCU and implementing Standby (low-power) mode in the firmware. Development is done using Arduino IDE v2.3.2. I want the standby mode to be implemented to reduce the current consumption since my device is battery-operated. Problem OverviewThe firmware flow is as follows:On power-up, setup() runs.In loop(), if the reset reason is a power-on reset, the device enters Standby mode.The MCU wakes up from Standby via an interrupt on PA0 (Wakeup Pin).Execution flow and timing are monitored using the Serial Monitor.With the same firmware and library versions, I am observing different behaviour on two PCBs that:Have identical schematicsAre manufactured by the same vendorObserved BehaviorWithout Standby mode implemented, both PCBs behave correctly.With Standby mode enabled:Serial prints before entering Standby appear corr

Hello,I am trying to integrate an STSAFE-A110 chip into my product for keys/data securely storage.The communication with the chip works fine (approved by simple command as echo or generate_random).So I tried to generate a key in a local envelope key slot (first step of command flow in the "Local envelope wrapping/unwrapping" process). For that I queried the STSAFE-A110 to randomly generate a local envelope key in slot #0 and #1, using the STSAFEA_CMD_GENERATE_KEY (0x11) command.> 11 07 00 00 AF C1> 11 07 01 00 B6 19The chip answers OK as status code (correct crc) but I missed to keep data.But when I query the STSAFE-A110 to retrieve local envelope keys information (slot number, presence & key length), I get a key presence flag to 1 but with zeroed key length for the 2 slots.> 14 07 89 09< 00 00 09 02 00 01 00 01 01 00 FC 88status=OK(0x00)slot_nb=2Slot #0:- key_presence=1- key_length=0Slot #1:- key_presence=1- key_length=0How is it possible?Unable afterwards to gene

Hi,We are trying to make use of the ethernet interface in this fashion:- The board is a custom one with a soldered module from Karo, the qsmp-2550, that includes an stm32mp255fa.- The eth2 is connected to a PHY (TI DP83869HM) in RGMII.- The PHY is then configured to output Base100-FX to an SFP cage.- There is no CLK125, we use ck_ker_eth2 configured at 125Mhz (confirmed in /sys/kernel/debug/clk/stm32_clk_summary), we use the `st,ext-phyclk` DT property.The PHY is reachable via mdio using the CLI from mdio-tools and seem to be working as intended.We checked that the PHY sends the correct clock, the RX one, with a scope: it does.Then when enabling the link using `ip link set up eth0` we are greeted with:```root@qsmp-2550:~# ip link set up eth0[ 16.583371] stm32-dwmac 482d0000.eth2 eth0: Register MEM_TYPE_PAGE_POOL RxQ-0[ 16.586971] stm32-dwmac 482d0000.eth2 eth0: Register MEM_TYPE_PAGE_POOL RxQ-1[ 17.123948] stm32-dwmac 482d0000.eth2 eth0: PHY [stmmac-1:00] driver [TI DP83869] (irq=

I just like to configure the ISM330DHCX for vibration measurement. Is that an example or a sample code(using its C driver ) of it somewhere. Please give me a pointer. Thanks.

In AN2606 Rev 69, the STM32WBA6x system bootloader section describes the UART interface as USART3, but there appear to be errors:1. Inconsistency within the same entry:The TX pin description mixes USART2 and USART3 in the same sentence:USART3_TX pin Output PA12 pin: USART2 in transmission mode. Kept in reset configuration until 0x7F detected on USART_RX.While the RX pin description correctly uses USART3:USART3_RX pin Input PA11 pin: USART3 in reception mode. Used in alternate push-pull, pull-up mode.2. PA11/PA12 are assigned to USART2, not USART3:According to the STM32WBA62 datasheet, PA11 and PA12 are mapped to USART2 (USART2_RX / USART2_TX), not USART3.Question:Does the STM32WBA6x system bootloader actually use USART2 on PA11/PA12? It seems the document should read USART2 throughout, and the current "USART3" label is an error.Could ST please clarify and correct this in the next revision of AN2606?Environment:- Document: AN2606 Rev 69- MCU: STM32WBA62CGU6- Section: STM32WBA6x boo

Hi, I'm developing a project for STM32N657X0HxQ MCU and I need to run a NN model on it. I installed the 10.2.0 package for X-CUBE-AI and I've selected Core for Artificial Intelligence X-CUBE-AI in the Software Packs component selector. However, whatever Device Application I select, I always get when I'm on the Configuration Tab in Pinout & Configuration "Warning: This peripheral has no parameters to be configured" and I cannot upload my NN model, even when Artificial Intelligence X-CUCE-AI checkbox has been selected.I'm using the 6.16.1 Version of STM32CubeMX.Thank you for the cooperation

In section 19.6.2 LCD frame control register (LCD_FCR) of the STM32U0 RM0503 Reference Manual, the examples provided for PS and DIV initially count up in decimal, but finish in binary. This looks like an accident and is confusing to the reader. https://www.st.com/resource/en/reference_manual/rm0503-stm32u0-series-advanced-armbased-32bit-mcus-stmicroelectronics.pdfAll other examples further down in section 19.6.2 correctly count up in binary and do not mix in decimal numbers:

Hi Guys. I am just trying to receive data from sensors accommodated on STEVAL-BCN002V1B (Blue Tile board) using application  "BLESensorDemoCentral" running on STEVAL-IDB008V2  board.I am able to detect all services that are advertised by Blue Tile board using "BLESensorDemoCentral" application running on STEVAL-IDB008V2 board, which are "ServW2ST", "ConsoleW2ST" and "ConfigW2ST" services.But I am still unable to find characteristics of all the three services described above. Q1 : What changes ( Master context object ?, gatt callbacks ? ) shall be done on side of "BLESensorDemoCentral" application running on STEVAL-IDB008V2  to get all characteristics of all services  that are received from  by Blue Tile board  (STEVAL-BCN002V1B)?Q2. Does somewhere exist a code, that I could use as clue ?Thanks for Your hints.  PQ.

Hi,I am using the application core of the STM32WB55VGY6 (not the radio core). I created a CubeMX project and added a simple HAL_GPIO_TogglePin() call. Literally just 2 lines of code in the entire project.When I use a for loop as a delay, the code works as expected. However, when I use HAL_Delay(), it does not.For some reason the SysTick_Handler() is never called... I’ve attached the full project, including the .ioc file. The application code itself is minimal (only two lines).From the configuration:The timebase source is set to SysTickInterrupts are enabledThe SysTick_Handler() is generated, but it is never triggeredHas anyone encountered this on the STM32WB application core, or have any suggestions on what might be missing or misconfigured?Thanks. 

I am using stm32l552zetxq. I am testing standbymode with wakeup from event. According to reference manual RM0438, there are 5 wake up pin to wake up the mcu from standby/shutdown mode wkup1 to 5 with polarity setting option in PWR_CR3 and PWR_CR4. But i could not find whic are those 5 pins in datasheet and in reference manual. By searching i find that PA0,PC13,PE6,PA2,PC5 in a documents ""en.STM32L5-System-Power_control_PWR.pdf" in page no 40. Now my question is what is the wkup no of which pin. It should be mentioned either in data sheet or in reference manual. It be very help full to me kindly provide the document with page no or article number and te documents.

Hi, so the recent change to make CubeMX a separate app has broken my old project. I am using a Nucleo board and HAL in the project. After a change to the .IOC file I get "stm32h7xx_nucleo_conf.h:50: warning: "USE_NUCLEO_144" redefined". Is there a resource somewhere explaining to to do all of the after the CubeMX split? 

Hi,I would appreciate any guidance or best practices for minimizing code size by eliminating unused functions when using the STM32 extension for VS Code with CubeMX generated code (bare metal) as some code I'm writing has become very large.What is the recommended way to configure the compile/build process so that unused functions are not compiled or linked into the final image flashed to the microcontroller, in order to save flash space?I am not familiar with CMake, so if this can be achieved without using CMake, that would be preferred.If custom configuration text is required (for example Makefile edits or similar), could you please outline them in detail and whether these changes are generally safe, or if they require careful consideration.Any clarification on the recommended approach would be greatly appreciated.Thank you

Hi,I am using a STM32C031G6U6 and I would appreciate some clarification regarding HAL timebase and SysTick timebase selection.I want to use SysTick as a 1ms interrupt so in CubeMX I selected SysTick as timebase (see screenshot): None of the other timers - including TIM3 - are not enabled as shown here: These are the other settings:  I then generated the code. But there is no sign of any SysTick related functions/handlers in the interrupt file stm32c0xx_it.c as you can see here: /* USER CODE BEGIN Header */ /** ****************************************************************************** * @file stm32c0xx_it.c * @brief Interrupt Service Routines. ****************************************************************************** * @attention * * Copyright (c) 2026 STMicroelectronics. * All rights reserved. * * This software is licensed under terms that can be found in the LICENSE file * in the root directory of this software component. * I

Hello,I may have made a *** of myself on a prototype, and need a bit of help with a work-around. I have an external clock signal on TIM20_ETR (PG5) for some pulse counting stuff. This works.However, I intended to use the same clock signal to trigger TIM2 one-pulse (and later TIM5 one-pulse as well), and thought that I could use tim_trgo from TIM20 to clock them. My problem is that, now I have the prototype PCBs in hand, I cannot figure out how to pass the TIM20_ETR clock signal on to tim_trgo – or if it is even possible.My best guess is that I can set TIM20_CR2 MMS to 0010 (Update), and set PSC and ARR to 0. I have already set TIM20_SMCR to use TIM20_ETR as the trigger source. If I understand the timer functionality correctly, this should give me an update event for each clock pulse.This work-around will make me lose the TIM20 counter feature, but if I can just get the external trigger signal out on tim_trgo, then I can use that to clock TIM1 or TIM8, which can then be used for the act

Hi,i am using STM32G0B1KB and the UCPD peripherals to implement an USB-PD device with 2 ports:- Port 1 is DRP- Port 2 is Source onlyI need the dead battery pulldowns for port 1, so I will connect the UCPD1_DBCCx pins with the UCPD1_CCx pins as described in the manual. However, for port 2 I don't need to present the dead battery pull-downs - when the MCU is unpowered (dead battery) and the user connects some other device (e.g. smartphone) to port 2, simply nothing should happen. The manual states:> If dead battery behavior is not required (for example for source only products), then UCPDx_DBCC1 and UCPDx_DBCC2 pins must both be tied to ground.What resistance can be used to connect those pins to ground? Since I don't have any pins left, can I instead use the DBCC pins for something entirely different? E.g. connect LEDs (to GND) or some other digital output with a weak external pull-down resistor (e.g. 10kOhm)? Will this prevent the MCU from enabling the pull-downs?Thanks!

Board: NUCLEO-N657X0-QRevision: CProblem: MCU cannot pull PA2 to low, only to about 2.5V. I tried it in push-pull and open drain modes. SB6 has been desoldered to isolate it from the analog attenuation circuit, but it didn't work with it soldered. It doesn't work with the "GPIO_IOToggle" example project either, same behaviour. Pulling the pin up to 3V3 works just fine. PA2 is the pin so far which has caused this issue. Holding the reset button makes the pin go high (3V3), indicating a hardware issue, as far as I know. My best guess is it is somehow pulled up through a pull up resistor, but I haven't found any evidence of it in the documentation.I attached some documentation which I investigated.Any help is appreciated, thank you!

Hello,   hope everyone is well. I'm working on the software side for a micro mouse bot. We're planning on using the STM32G070RB for the microcontroller. For prototyping, I'm using the NUCLEO-G070RB. I separated the ST Link from the board, and wired the two together, as shown below (source and the schematic:( And here's the schematic below: When I flash a program (I use openOCD, but I've also tried STM32CubeIDE), it works until I unplug the ST-Link, then it doesn't seem to work until I plug it back in. Any advice? Am I missing an additional connection?  To clarify, the Arduino powers the Nucleo board.
