Hi everyone!I'm trying to validate an ONNX model on my STM32H747I-DISCO board, but I'm running into issues.I've successfully generated the project and flashed it onto the board. The validation process does run (using random inputs), but the final metrics I'm getting are all NaN.I'm using the FP32 version of the model (not quantized), and when I run the same validation on desktop, the metrics are almost perfect — so the model itself seems fine.I've tried enabling the --classifier option, but it didn't make any difference. I also attempted using --no-onnx-io-transpose, but got the following error: stedgeai: error: unrecognized arguments: --no-onnx-io-transpose Could this be an issue with my model, the CubeIDE project or am I missing something in the X-CUBE-AI configuration ? I've also noticed that there is a note in the csv file with the inputs:# Note: w/o datanumber of item by sample is exceeded: 4096 > 512Is this issue compromising the classification ?Thanks in advanc

HELLO guys could you please tell me how to put the stm32f746zg board in dfu mode actually earlier i was able to program and use the stlink to dump but currenty im not able to connect using stlink so i want to do with the dfu stm32 bootloader mode i have refered the manuals but  cant find the solution please help me in this .

We are currently working on project, for which we are using the NUCLEO-G431RB development board. As we are now planning to move towards production of our devices, we require both the schematic and the Bill of Materials (BOM) for this board.I got schematic but not BOM if it is possible then please share the BOM.Thankyou.

I used a custom development board, chip model STM32G474 to develop functions related to dual motor control, but when producing the cubemx project, the tip: Unable to generate ioc file due to: Negative index not allowed: -1...Version info:MC Workbench: 6.3.0WB_to_Mx: 6.2.3.template-24-04-17STM32CubeMX: 6.10.0MC Firmware Library: 6.3.0-Full Project attachment (.stwb6) and control board configuration file (.json) in attachment, suffix changed to TXT due to upload restrictions 

I'm trying to run a sample PWR_DEEPSTOP_RTC from PWR_DEEPSTOP_RTC, but I'm facing some problems.The code works correctly, the UC enters deepstop mode and returns to run mode, but when I try to measure the current in PJ2 as described in item 7.1.4 of UM3345, I get 90uA when in deepstop mode and not around 1uA as the datasheet says. (RTC wakeUP, LSi 32k).I follow this example recipe:/* The following Wakeup sequence is highly recommended before each entry into Deepstop modeespecially when using more than one wakeup source, this is to not miss any wakeup event.- Disable all used wakeup sources,- Clear all related wakeup flags,- Re-enable all used wakeup sources,- Enter Deepstop mode.*/Is there anything I missed or didn't understand?

Hello Community, Am interfacing LIS2DTW12 Acceleration Sensor with STM NucleoL476RGT6U by I2C communication protocal in  blocking mode working everything fine. But i want collect data in non blocking mode so collecting data to DMA and implementing the custom callback but control not coming to custom call back (custom callback was not triggered ) if i stop the program data will present in the Data array .While Debugging DMA transfer complete interrupt triggered succesfully when going to handle DMA_IRQ Handler during that time am check the I2C state thats still HAL_I2C_STATE_BUSY_RX Whats the issue ?if i forcefully Change the I2C state to ready and forcefully call the custom implemented callback then it will work .May i know Whats happening whats the issue is from hardware side or software ?Anyone helpme to resolve this ....MX_GPIO_Init();MX_DMA_Init();MX_I2C1_Init();SensorLIS2DTW12Acc_init();start_dma_read();void SensorLIS2DTW12Acc_init(void) {// Read the WHO_AM_I register to verif

Hi   I have a a stm32L433 48 pin processor and trying to get it into low power. I am using the STLink-V3PWR module with stm32Cube Monitor Power module.   First of all I placed a known value resistor across the STLink-V3PWR to make sure it is reading the correct value, then tried the following: 1. I am using a MIC5219-3.3YM5-TR from the input with the STLink-V3PWR set to 3.6v.  And on its own it draws 85uA.2. I then added all the resistors and capacitors needed and it measured 96uA.3. I added the STM32L433 and programmed it to first run for approx 5 seconds in normal mode (16MHz), then drop into standby mode. On the output you can see it drop quite a bit, but the lowest current is approx 650uA (far too much current) as you can see on the graph below. My code is below after 5 seconds of normal operation. I tried HAL_PWREx_EnterSHUTDOWNMode(); without Putting the Ram in Retention, but still the same,void EnterLowPower() { RCC->APB1RSTR1 |= RCC_APB1RS

I am trying to deploy a model onto a STM32N6570-DK board. And I encountered some warnings that the Cube-AI cannot support the unsigned int weight and it cannot support other layers such as linear_dynamic and ATen. Iam wondering where I can get some information about what layers or other things the X-Cube-AI actually support so that I can fix may models.

I am trying to connect to the b-u585i-iot02a on macOS 15.3.1 using OpenOCD without success. The same board, cables and configuration scripts with the same version of OpenOCD (0.12.0+dev-01888-ga168c6341) works on both Windows 11 and Ubuntu 24.04. ST-Link server also does not work.OpenOCD and included with STM32CubeIDE 1.18 also seem to run into the same issue so this does not seem to be specific to the official release.The board has been updated to the latest stlink firmware (v3j16m7).I have attached the OpenOCD -d3 log.It might be helpful to note that I have no issues with a Nucleo-F411 board on the same macOS machine.I would appreciate any help or advice anyone can provide.

Recently I changed from Windows to Linux. Now I'm working on a older project and when debugging I got the message "program file does not exist" wit the details:.../Projects/VxxT/VxxT_firmware/Debug\VxxT.elf not foundI've found that the problem is the backslash in the path and that this is an artifact of changing operating systems.My question is how to correct this so the IDE looks for the right file?

Hii,I am working on a project using the STM32 Smart Presence Detection. In order to run the program and get the detection for the person and get some detection readings which file and what are the steps should I follow? I have extracted the STSW-IM048 file and I have played with the EVK interface and now I am struggling to use this algorithm to implement this system to my robot.

Can the STEVAL-CAM-M0I evaluation board used together with the VD55G0 promodule? ST's marketing material seems to suggest it can, but looking at the schematics of the STEVAL-CAM-M0I the power rails are turned on in the order VCORE first, then VANA, then VDDIO. However, in the VD55G0 datasheet it is mentioned in section 8.3 that AVDD (VANA in the eval board) has to be turned on after VCORE and VDDIO. Is the datasheet outdated? Other sensors like VD55G1 or VD56G3 do not have any power sequencing requirements.Thanks a lot!Michael

I have purchased STM32H757I-EVL board for working. I have not found SDK for this board. But as one of site suggest downloading STM32CubeH7 package, I did same. In this package I couldn't find example project for STM32H757I-EVL board.So, I have start working with STM32H743I-EVL example code and compile Thread Creation example. Now I am flashing generated .elf file to STM32H757I-EVL board but this application is not working, and LED is not blinking. I have soldered resistor for LED that is only change on board. I have checked schematic for both board and found it is pin compatible. Now I am stuck to go further. Please anyone found this type of issue or help on this. Meanwhile I will try further and debug issue.Example code path is STM32CubeH7\Projects\STM32H743I-EVAL\Applications\FreeRTOS\FreeRTOS_ThreadCreation\STM32CubeIDE.

I am new to TouchGFX interface. I am trying to create GUI for the custom LCD hardware of size 240x320 communicating with ILI9341 LCD drivers. The touchgfx builds the code and runs appropriately in the simulator., but the same is not working with the hardware. screen switching with the images in it works absolutely fine but without the text.The MCU in use is STM32U575V.Touchgfx version is 4.24.1The images and font is placed in the internal flash as there is no space constraint for my application. ( Most of the demos or examples use external Flash for images and fonts).Using a custom Font for my application (default font Verdana didnt work as well)so the settings considered are as followsThe *.icf file image     2. the settings in Touchgfx With the setting to unmapped storage format in Config, the images are getting displayed on the screen and switching of the screen also works fine. (No text is displayed on the screen)Since the texts are not working for me. I ch

I’ve been testing your TVS simulation tool (https://eds.st.com/tvs/#/), but I’d appreciate some clarification on its methodology. Could you detail:The relationship between input parameters and the recommended TVS devices?The underlying algorithms or calculations used in the tool?

Hi,    I am using the STM32H7A3 board to implement the virtual serial port function for USB, and I want to use FS mode. However, there is no macro definition related to FS mode in STM32H7a3xx. h. Do I need to manually add it? And I checked the demo in the development package, but there is no demo of H7A3 regarding the virtual serial port. Can you provide it? Currently, I am referring to the USB virtual serial port demo of stm32H743l for porting, following the HS mode, but the computer does not recognize the USB interface.

Hi. I am designing Schematic for STM8L050J3 chip. In that, pin1( first pin) , in datasheet they mentioned as SWIM in port A0 of pin1 and USART TX in port A2 of pin1. I want to use this pin as SWIM for programming as well as USART for data transmission. How can i use that? Is there a way?  

As the title, I can't get the difference between the Model and ModelListener.From what I've understood the Model class is used to get and store/send the data coming between the phisical part of the microcontroller (i.e. peripheral) and the GUI. The ModelListener instead is the interface that checks if these data have been updated and inform specific Presenters when needed.I have kind of understood the documentation provided here but, first of all, why in the Model.cpp it checks if modelListener != 0?I can't understand where and how modelListener takes its value.I've checked the E-Bike Demo and the process of passing data from the Model to the GUI is a little bit difference. In the Demo the Model.hpp has a bind functionvoid bind(ModelListener* listener) { modelListener = listener; }With the ModelListener.hpp having another bind to the Model classclass ModelListener { public: ModelListener() : model(0) {} virtual ~ModelListener() {} void bind(Model* m) { model =

I would like to know the necessary operations and settings from power on to GPIO control.I have made a board using STM32H743XGH6.I want to set the GPIOs to turn on the LEDs, but it does not work.I am setting the GPIOs by manipulating the registers directly with JTAG.I would like to know what other settings are necessary before I can get the GPIO to work.(For example, set this register here, etc.).Sorry for the general explanation.Assuming there is nothing wrong with the circuit, any advice would make me happy.

Hello,I'm trying to get the DebugPrinter to work on an STM32H7S78-DK, but the debug message does not appear to be properly refreshed after the Application::invalidateDebugRegion(); The area slowly turns into a black rectangle after each text update. TouchGFXConfiguration.cpp shows:    static LCDGPU2D_AXI display;I don't see an hpp file for this. Is there a solution? Have tried LCD16DebugPrinter.hpp and LCD24DebugPrinter.hppThanks,The Windmill

1. [Part Number] NUCLEO-WL33CC1 2. [Environment] Windows 11 laptop3. [Schematics] Using ST Nucleo board.4. [Details] STM32CubeIDE would not enter debug.5. [Expected behavior] It should enter debug after a power reset regardless of what low power mode6. [How to reproduce] Simply program standard ST MRSUBG_WakeupRadio_Tx example7. [Occurrence] The problem is constant8. [Sanity checks] Changed cable. Confirmed boards with STM32CubeProgrammer.I found that when I run the default ST MRSUBG_WakeupRadio_Tx example program, I am no longer able to enter debug mode or reprogram the device using the STM32_Programming tools (both GUI and CLI).Is this expected behavior? If so, I would appreciate an explanation as to why this happens. My assumption is that regardless of how the device enters low power mode, a power cycle reset should allow the debugger to reconnect.Is there a workaround for this? I find this issue qu
