Hello, I wrote a project maybe 2 weeks ago, at that time, everything was ok.  then i used stlink to download and debug the code yesterday, at first time, it worked ok, but later, i did download and debug again with stlink. it cannot work. the log as below.my setting as below:so what is the problem? how to fix it?thanks. 

Hi, I'm developing a board to control motors using FOC. For this, I will use the MC workbench tool to generate the code. However, when I describe the hardware in the shunt resistors section, there is no "in-line" option, only the low-side option, but my board only has them in-line and I can no longer modify it. What can I do in the code to be able to use the shunt resistors in this way?

 Hi everyone,I wanted to share a project I’ve been building over the last few years. It’s called Mk, an operating system built entirely from scratch for the STM32F746G-DISCO and STM32F746G-Eval2 boards.These boards are powered by an ARM Cortex-M7 running at 216MHz. Initially, my goal was just to implement a small scheduler, but I stacked layers one after another to make it as complete as possible. Currently, I think I've added enough layers to claim it as a functional, lightweight OS.Mk features:A KernelPreemptive, priority-based multitasking scheduler (fixed-priority, O(1) selection via hardware CLZ instruction) Trusted Execution Environment (TEE) using the Cortex-M7 MPU (privileged and unprivileged mode isolation) Synchronization primitives: mutex, semaphore, event flags, mailbox Fixed-size memory pools Synchronous and asynchronous callback execution systemA Dynamic ELF Loader Mk can load and execute external .elf binaries at runtime, relocated dynamically into 64 KB pages of the ext

Hello,   I am working on I3C private transfers. When I build the context buffer with HAL_I3C_CTRL_BuildTransferCtxPrivate I get an assert when IS_I3C_PRIVATE_MODE is checked against HAL_I3C_PRIVATE_WITH_ARB_RESTART. Is the exclusion of HAL_I3C_PRIVATE_WITH_ARB_RESTART from the macro below intentional? stm32c5xx_hal_i3c.c: line 574 #define IS_I3C_PRIVATE_MODE(MODE) (((MODE) == HAL_I3C_PRIVATE_WITH_ARB_STOP) \ || ((MODE) == HAL_I3C_PRIVATE_WITHOUT_ARB_RESTART) \ || ((MODE) == HAL_I3C_PRIVATE_WITHOUT_ARB_STOP) \ || ((MODE) == HAL_I2C_PRIVATE_WITH_ARB_RESTART) \ || ((MODE) == HAL_I2C_PRIVATE_WITH_ARB_STOP) \ || ((MODE) == HAL_I2C_PRIVATE_WITHOUT_ARB_RESTART) \ || ((MODE) == HAL_I2C_PRIVATE_WITHOUT_ARB_STOP))  Thank you, -Gil

Hello, I am looking for an example of how to use private I3C transfers for STM32C562RE. I read the I3C examples posted on Github but I did not find any controller or target examples that use HAL_I3C_CTRL_Transfer_DMA and HAL_I3C_TGT_Receive_DMA for private transfers using HAL2. Your help would be appreciated,Gil

Hi~ My board gets stuck at the kernel stage during boot. I've referred to numerous related posts but failed to resolve the issue.The boot file versions I use are OP-TEE 4.0, U-Boot 2023.10 and Linux 6.6.116.The official device tree I referenced is stm32mp157f-ed1.I have attached the boot logs, hardware schematic and device tree files.

  i am installed cube-MX for linux laptop version (6.17.0) and cube-IDE is (Version: 2.1.1) .For MX it shows option only generlic linux  so it is correct for linux laptop ? and for IDE is debian is fine . I refer you tube sessions for Example import in that STM32IDE option availbale as toolchain but in my system sometimes not shows . Can you please give me exact steps how can i use Mx with IDE in detail steps for import examples given by stm32 also how can i create and import new example also .  Also i have board STM32-NUCLEO-F746ZG when i import example in MX sometimes board is not visible .For toolchain selection below options are availble in that STM32IDE is invisible .  

When generating a CMake-based STM32 project, STM32CubeMX currently lists every single .c source file manually in CMakeLists.txt. This brings major inconvenience for users:When adding user drivers (e.g., sensor, flash, display, or custom modules), users must manually edit CMakeLists.txt and add each new .c file path.If the user adds many source files, this process is error-prone and inefficient.It does not match modern CMake project practices and reduces project maintainability. Suggestion:Please use file(GLOB_RECURSE ...) to automatically include source files from standard directories such as:Core/Inc/*.hCore/Src/*.c

Hi all,I'm running standalone STM32CubeMX on Debian and I'm having trouble generating a complete project. No matter what I do, code generation only produces three items:- led_test.ioc- Inc/ folder- Src/ folder I'm expecting a full project structure including Core/, Drivers/, startup files, and a .launch file for STM32CubeIDE.Steps I've already tried:1. Selected the NUCLEO-F334R8 from the Board Selector (not the MCU).2. Clicked Yes to initialize all peripherals with default settings.3. In the Project Manager tab, set the Toolchain / IDE to STM32CubeIDE before generating.4. Clicked Generate Code — same incomplete output every time.Has anyone run into this on Debian? Is this a known bug with the standalone CubeMX on Linux, or am I missing a step? Any advice appreciated.ThanksI've attached screenshots of my CubeMX configurations settings below:

Recently, I was trying to implement SDMMC+DMA+SDFAT to read and write the SD card of my Class on the STM32H750VBT6. Then I found that the DMA of SDMMC was gone. I saw some online materials saying that MDMA needs to be configured, and some also said that SDMMC does not need to configure DMA as it has its own independent IDMA bus. What is the actual situation when it is directly mounted on AHB? Are there any configuration screenshots and programs of CubeMX for SDMMC+DMA? I'd like to refer to it. Thank you!

Does the ST67W611M1  (-B version) with PCB antenna have a built in rf switch? We want to programmatically or via pins switch between the PCB antenna and an external antenna.

Dear. AllI'm asking how to use STemWin on stm32h743 mcu.How to add STemWin on STM32CubeIDE? (Current Use Version. 1.13.0)?How can I run a project with the development board I bought? (STM32H743I-EVAL)?In particular, I want to run the STemWin_SampleDemo project.I`m use IAR EWARM ver 9.xx but in stm32cubeh7-v1-12-1 andSTM32Cube_FW_H7_V1.11.0\Repository\STM32Cube_FW_H7_V1.11.0\Projects\STM32H743I-EVAL\Demonstrations\STemWini find STemWin.ewp project which use OGLastSavedByProductVersion 8.20.2.14834.It mean`s STemWin.ewp should compile on EWARM 8.20 or late.Is it possible to use example on later version EWARM ?Best regards.

Hi, I'm using the STM32C071K8U6's built-in USB DFU bootloader for one-time production programming. After flashing, PA11/PA12 (USB D+/D-) are used as regular GPIO outputs to control two P-MOSFETs (each with their 100kΩ gate pull-ups to 4.2V).   The USB functionality is not used by the end customer, but the USB connector remains accessible for charging. This means a PC's USB cable may be connected during normal use allowing for potential signal injected into those traces resulting into the PMOS being turned on/off by the PC if it detects there is a USB device connected and tries to enumerate it.   The two core issues: a) When a user plugs into a PC for charging, we need to guarantee the host does not attempt enumeration, and that nothing the host does on D+/D- interferes with our GPIO-driven MOSFET gates. b) because the PA11 and PA12 traces also go all over the PCB - i.e. they form very long stubs - we need to make sure this does not prevent the USB from working properly d

The STM6905 datasheet says in Table 2 that there is an internal 10k pull-up on RST#, which seems wrong since that's an open-drain output. Then in Section 2.6 and in Section 3 it says that an external pull-up to VCC should be used.

Hello,I would like to ask about the UFQFPN32 package footprint for the STM32G491KEUx device.We are using the following part:Part number: STM32G491KEUxPackage: UFQFPN32While reviewing the datasheet and package information, we found that the actual UFQFPN32 package appears to have an exposed pad (EP) on the bottom side of the package.However, in the datasheet/package information we reviewed, the UFQFPN32 package information and footprint example do not seem to include the EP or the EP land pattern.In particular, the UFQFPN32 package information is shown in the document from page 166 to page 168, but we could not find any information regarding the exposed pad or the recommended PCB land pattern for the EP.Could you please confirm the following?Is the exposed pad information for the STM32G491KEUx UFQFPN32 package omitted from the datasheet/package information?For actual PCB design, should we include an EP land pattern for the UFQFPN32 package?If the EP land pattern should be included, shou

Hi everyone, I'm facing issues connecting an external debugger to the NUCLEO-H7S3L8 board (STM32H7S3L8). Current Setup: Board powered via CN5 (ST-LINK USB) JP1 closed (to disable on-board ST-LINK) External debugger connected to CN1 (MIPI20 connector) SWD mode at low speed (500 kHz to 1 MHz) Correct power sequence: Power CN5 first → wait for COM LED (LD8) to stabilize → then connect external probe What I have already tried: BOOT0 = 1 (jumper on CN11[5-7]) to enter bootloader mode and halt using external debugger Internal ST-LINK works fine when JP1 is open (using STM32CubeProgrammer) Problem: The external debugger is unable to connect or halt the CPU, please guide me how to fix it. Thanks,regards,Surender.

Hello All,Apologies in advance for sounding like a noob (that is because I am). I am building a wearable device as a hobby, and I need a 6-axis gyroscope with IMU. Ideally, the device should have more than one IMU, but considering that I have absolutely no idea how to even assemble the device, I am reaching out to this forum to hopefully get an initial idea of what it is I need, so as to hopefully set me off in the right path. The sensors I am thinking in using: Initially I have been looking at ASM330LHHTR and A3G4250DTR, strictly because they are small. The idea I have is to begin testing with a simple setup connected to power, but to eventually make it battery-powered.A bit more information about what I want to measure: eventually I want to set up a strip of these IMUs in a straight line, and have them measure at the same time, and feed it to something like a raspberry pi so as to transmit BT signal. To make a setup where I have IMU --> [something] --
