STM32 MCUs

Hello, In a paused debugging session, in the Run and Debug > Variables > Local list, if I right-click the varaible, the context menu has an item "Show in Memory Inspector".Clicking it opens the Memory Inspector, but with the name of the variable as the adress ( &(pRxData) for example), which the memory viewer cannot resolve into the actual address (0x20003DC0 for example). For this functionality to be most useful, I would expect either the Memory Inspector to be able to resolve the variable, or the command to open the Memory Inspector with the already-resolved address. Best regards,Nicolas

This had me stumped for a while - Thought I was going blind for a second LOL.PCLK1 and PCLK2 identifiers are missing from the clock tree diagram for the STM32H723.(They are present in the trees for F103, G431, F446 and F723). 

After generating the CMake project using STM32CubeMX (with the MCU being stm32f412ret6), how can FPU support be enabled in VSCode(STM32CubeIDE for Visual Studio Code)?

Hello, after updating to 3.7.0, my system no longer works. I can't debug and now get an error message. It was still working an hour ago. 

Hello ST community,I am working on an application on STM32N6570-DK using the camera to detect humans with an AI model (X-CUBE-AI + NPU) and draw bounding boxes on the LCD using LTDC.I am facing a display corruption / glitch issue that only appears under very specific conditions, and I strongly suspect an AXI / interconnect / NPU side effect, possibly related to an undocumented reset or QoS state.Project architecture:Camera -> DCMIPP -> PIPE1 -> BUFFER1 -> LTDC_L1                                 -> PIPE2 -> BUFFER2 -> NPU -> Config ROI of DCMIPPMemory placement:LTDC framebuffer: AXIRAM2AI input/output buffers: AXIRAM5No buffer sharing between LTDC and AIProblem description:When MX_X_CUBE_AI_Process() is commented, the camera preview is perfectly stable on the LCD.When MX_X_CUBE_AI_Process() is enabled, continuous display glitches appear (tearing / corrupted lines).The issue happe

Hi, I'm a newbee in this community and my first post is related to an already existing one: https://community.st.com/t5/stm32cubeide-mcus/stm32cubeide-with-svn-subversion-which-files-folders-to-ignore/td-p/253294  Usually we have \project\.settings\language.settings.xml under version control - but changes in this file seem to be not relevant to track it.

Hello,Regarding CubeMX 6.17, I'm trying to configure a STM32N657 project from scratch.   I'm looking for the driver for the ASP256 SRAM memory chip found in various examples and the STM32N6570-DK discovery board.  If I search the "Software Packs" I can't seem to find the device listed there.  Are these files missing or am i looking in the wrong place?  I found them on Github here: https://github.com/STMicroelectronics/stm32-aps256 but I figured that it should be available in CubeMX (or it would be nice if it was available).   If they are available from CubeMX, how do I extract and add the component to the project? ThanksMatt

In the FD_CAN register, there is a CEL[7:0]:, REC[6:0]: and TEC[7:0]:,The CEL register is not being reset on read and goes into the Bus-Off mode.Do I need to also reset the REC and TEC register?I am currently using the HAL_GetErrorCounter() function to read the register. 

 This time, my problem is not related to hardware or firmware.What happened was that when I closed Cube IDE during my lunch break, everything was normal... but when I came back and opened it again, the interface colors had changed, which I don't like, and personally, I find that appearance visually uncomfortable.As you can see in the attached image, the gray color where I write code seems to have a haze over it. How can I correct it so that it looks like a solid, dark tone like the part below? Thank you for your help. My eyes and I will greatly appreciate it.           

Hi,I wrote my own source file. It is located in the Core/Src directory. I have also entered it accordingly in cmakelists.txt.my cmakelists.txtNow I get an error saying that the include files from the Drivers directory are missing.If I remove my entry, I no longer get the error. But then I can't use my customs. Is there a sample cmakelists.txt that includes customs?Thank you,Funnypinky

Hello,I have STM32F7 controller, using Free RTOS, trying to interface external NOR flash, S29GL128S10TFIV13.So at first, I was trying to do normal read/write operation, but here what I observed,void FMC_Init() { hnor2.Instance = FMC_NORSRAM_DEVICE; hnor2.Extended = FMC_NORSRAM_EXTENDED_DEVICE; /* hnor2.Init */ hnor2.Init.NSBank = FMC_NORSRAM_BANK2; hnor2.Init.DataAddressMux = FMC_DATA_ADDRESS_MUX_DISABLE; hnor2.Init.MemoryType = FMC_MEMORY_TYPE_NOR; hnor2.Init.MemoryDataWidth = FMC_NORSRAM_MEM_BUS_WIDTH_16; hnor2.Init.BurstAccessMode = FMC_BURST_ACCESS_MODE_DISABLE; hnor2.Init.WaitSignalPolarity = FMC_WAIT_SIGNAL_POLARITY_LOW; hnor2.Init.WaitSignalActive = FMC_WAIT_TIMING_BEFORE_WS; hnor2.Init.WriteOperation = FMC_WRITE_OPERATION_ENABLE; hnor2.Init.WaitSignal = FMC_WAIT_SIGNAL_DISABLE; hnor2.Init.ExtendedMode = FMC_EXTENDED_MODE_DISABLE; hnor2.Init.AsynchronousWait = FMC_ASYNCHRONOUS_WAIT_DISABLE; hnor2.Init.WriteBurst = FMC_WRITE_BURST_DISABLE; hnor2.Init.Continuo

I have a dual core application running on an STM32H7 where I would like: the CM7 to tell the CM4 to enter stop modehave the CM4 enter stop modeat a later time, have the CM7 wake the CM4 from said stop modeIn the CM4 code, I'm doing this: HAL_PWREx_ClearPendingEvent(); HAL_PWREx_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFE, PWR_D2_DOMAIN);The problem is that HAL_PWREx_EnterSTOPMode is immediately exiting. I use the HSEM library for synchronizing all communication between the CM7 and CM4. I thought that maybe I had a case where the CM7 was notifying the CM4 via the HSEM library when I didn't want it to, causing it to wake. So as a test, I added an infinite loopwhile (1);after notifying the CM4 so that the CM7 wouldn't execute anything else. I know that debugging can/will wake the core. To confirm that the CM4 was getting the notification and calling the above HAL_PWREx code, I turn on an LED, delay for 5 seconds, then make the calls. After the enter function returns,

CubeMX does not generate .project and .cproject files for cubeIDE, when in CubeMX project it is selected to not use default firmware location, and path set to folder with STM32Cube FW from github. To reproduce:1 Open CubeMX2 Select File->New Project 3 Select chip,  in my case stm32g491ceu64 Open Project manager tab, enter name and location for the project, toolchain - stcubeide5 Uncheck "Use Default Firmware Location", Click Browse and navigate to a folder with github repository with cude FW package6 Go to "Code Generator" sub tab, select radio button "Add nevessary library files as reference in the toolchainproject configuration file"7 Click generate8 Observe folder content in the file explorer - .cproject and .project are missing. CubeMX version 6.16.1

I am using STM32H743 controller, LAN8720 Ethernet chip, and Keil5 programming softwareI am using the IAP function of the network port and need to write the received data to FLASH. I found that the data read at that address after writing was modified. I found during debugging that after the "netif_add" function in LWIP initialization was executed, the data of my flash address was modified. May I ask what happened.Here is my MPU configuration, I'm not sure if it's related to MPU configuration   uint8_t MPU_Set_Protection(uint32_t baseaddr, uint32_t size, uint32_t rnum, uint8_t ap, uint8_t sen, uint8_t cen, uint8_t ben) { MPU_Region_InitTypeDef MPU_Initure; HAL_MPU_Disable(); // 配置MPU之前先关闭MPU,配置完成以后在使能MPU MPU_Initure.Enable = MPU_REGION_ENABLE; // 使能该保护区域 MPU_Initure.Number = rnum; // 设置保护区域 MPU_Initure.BaseAddress = baseaddr; // 设置基址 MPU_Initure.Size = size; // 设置保护区域大小 MPU_Initure.SubRegionDisable = 0X00; // 禁止子区域 MPU_Initure.TypeExtField = MPU_TEX_LEVEL0; // 设置类型扩展域为lev

Hi ST Community, I'm wondering if there's a sample project for a UART Bootloader for the NUCLEO-H755ZI-Q series. Thanks for your support  

Starting my design on a reference design based on STDES for WL3 series. I would like to know what is needed for the smallest hardware connection to download a program from ST32CUBE IDE. I need to have the minimum amount of connectors on the board. I.E. I don't want to plug in my board that I designed to the NUCLEO base board debugger for downloading  a program if I don't have to.  Can I take advantage of the STDC14 connection on the ref Des and if so, do I need some external piece of hardware to connect to it which then connects to the USB port on a computer?  Thanks!

Hello,I am planning to use BLDC motors in a robotic manipulator where torque control of the motors will be established. Thus, FOC SDK of STMicroelectronics will be utilized. Since the manipulator will be a parallel one, none of the motors will need to make one full revolution and they will work in low speeds as well. They will be equipped with encoder to measure the rotor position that is critical to FOC. Also, the zero position of the motors will be known prior to the running of the manipulator and so absolute position measurement will be no problem.My question is as follows. Can BLDC motors be used in the above mentioned application utilizing the FOC SDK? As I know, sensorless estimation of rotor position requires the spped to be relatively high. However, HFI (high frquency injection) technique of STM can overcome this issue and can estimate the rotor position at low speeds and even at standstill. Only requirement is for the motor to be an interior PMSM. Then, in case of encoder, the

When I was using Keil and VSCode with the same piece of code, I found that I couldn't enter the ADC_DMA interrupt callback function when using VSCode. I was looking up the information and debugging in two software programs. I found that the address of the array where I stored the data was 0x20 in VSCode, while it was 0x24 in Keil. I attempted to adjust the array address to the correct one, but found that it couldn't be adjusted properly.If there is a solution, please let me know. Thank you.

I've built cmwx1zzabz_0xx project on B-L072Z-LRWAN1 discovery board. From the source code, it looks like the app configures a 9600 baud serial console using UART1 on the STM32LO72 on the MuRata LoRa module.Please confirm that the TX/RX signals are available at PA9 and PA10 on the discovery board's pin header.Which #defines are necessary to route app console logging as well as AT command responses to this console?Thanks,Curtis

Hello,I am using an STM32H753IIT6 AA184 VQ V TWN AA. It does not communicate when I connect my serial board through serial communication and try to upload a TTL file using TeraTerm. The device is not even detected. However, when I replace the chip, it starts communicating normally. This has happened with multiple units and the result is the same.We verified that there are no soldering issues—X‑ray scans showed no defects. We have also tested all voltage levels and clock signals according to the datasheet, and everything appears correct.I am concerned about what might be causing this issue. Could you please help me understand what could be going wrong?Thank you.

Hello ST Community, I am working on an ultra-low-power project using STM32 MCUs and I have a question regarding the current capabilities of STM32CubeMX. Current Situation: I am aware that STM32CubeMX has an option to "Set unused pins to Analog" to save power. However, this is not sufficient for complex low-power management. In many cases, pins that are actively used in "Run" mode need to be reconfigured into specific states—not necessarily Analog—before entering a low-power mode (e.g., keeping a specific Pull-up/Pull-down for an external sensor, or maintaining a specific Output level to prevent leakage through external circuitry).Currently, CubeMX generates a single initialization function (e.g., MX_GPIO_Init()). To manage transitions for these "used" pins, we must manually write wrapper functions to change their states before sleep and re-initialize them upon wake-up. This manual process is time-consuming and prone to configuration errors. My Question: Is there an exist

Hi everyone. Following my Previous post, I have acquired a F446 Nucleo supporting 3shunt topology with the IHM17M1, such that I can perform motor profiling. However, I have run into an issue with the profiler getting stuck at 28%. Details are given below. Any help would be appreciated.[PN]: X-Nucleo IHM17M1, Faulhaber 0620-006B[VERSION]: 6.4.1[TOOL]: MC PROFILER[DETAILS]: Motor Profiler is stuck at 28%. The motor spins up in open loop mode. I have tried multiple speeds and currents within the motor range, and they all seem to work relatively well. However, when using the motor profiler, the motor does successfully spin up (enough current, I assume), but then stops before it reaches the target speeds, and then keeps retrying at a lower and lower acceleration. I have also tried a wide range of speeds from 5000RPM to 50000RPM, and all currents from 0.1-0.3A. I suspect it is not a startup error, but rather a sensing error. Given the size of the motor, and the operating current, I have cons

Good morning.Using CubeIDE both v1.19 and v2.0.0 with Debian Linux v11.11.I'm seeing very high processor usage, 300% and higher, all of it java based even when there is no activity in the IDE.  Is there an explanation available for this usage, or is there a way to bring the usage back down out of the stratosphere, or is there just a leak that's causing this?  It doesn't really appear to be affecting anything bigtime so this is just an information inquiry.  System monitor screenshot attached.Just for information, I was using IDE v2.0 for a few days then found it upgraded to v2.1.  v2.1 uses a later version of libc and doesn't run on my Debian 11.11 system.  Thanks,TJM 

[PN]: NUCLEO-G431RB with EVLDRIVE102BH and custom motor[VERSION]: Version: 6.4.1 Build: 250722.104358[TOOL]: MC PROFILER[DETAILS]: I am attempting to build a new motor controller that runs sensorless FOC instead of 6-step and my first step was to use the profiler to verify some of the figures on the motor's datasheet. Specifically the friction and inertia values on the datasheet seemed suspect and didn't have the right units for the motor controller workbench. Furthermore I'm assuming the gearbox included on the motor doesn't take these values into consideration. When attempting to run the profiler I seem to get stuck at 28%, which seems to be a common issue and it sounds like the issue is the motor not reaching a stable speed per the forum posts I've already read. From what I can tell it seems like the motor is physically spinning at a stable speed and I don't know why the profiler is struggling to read the speed. I have been banging my head on the wall for weeks now an
