Solved

Hello, I am working on a visual inertial odometry system. It basically contains a camera, a vision processing unit and an IMU. For vision processing part I was thinking of the STM32N6. Can you elaborate on the performance of the ST Neural-ART processsor? Can you elaborate on the inference time? How many images per second can it process?

Hi everyone,I'm deploying a model on the NUCLEO‑H563ZI using NanoEdge AI Studio (v5.2.0). My full training dataset is about 2 GB, and I cannot downsample or reduce features – I must use the complete dataset.My PC specs:- CPU: 12th Gen Intel i7‑12700 @ 2.10 GHz (16 cores total)- RAM: 32 GB (31.7 GB usable)- Storage: 1.82 TB HDD (mechanical drive, WDC WD20EZBX‑00AYRA0)- OS: Windows 64‑bit- Cores allocated to benchmark: 16 (all available)In a previous test with only 40 MB of data, the benchmark took 40 hours on this same machine. If time scaled linearly, 2 GB would take ~2000 hours – impossible for our schedule.Since I cannot change the dataset itself, I'm looking for practical ways to reduce benchmark time through external measures. Specifically, I would like to know:1. Storage bottleneck – My dataset resides on an HDD. Would moving the entire NEAI workspace and dataset to a fast NVMe SSD (or even a RAM disk) dramatically cut the time? Does NEAI repeatedly read from disk during benchmark

  I am using STM32F411CEU6 Black Pill from WeAct. Stlink was working I was able to flash the code but now after testing when I tried to connect it wouldn't connect I keep getting this error. I am using stlink clone.  USB under DFU mode gets connected, full chip erase works but when I try to flash the code I get this error      Please help me out

I am working on STM32G474RE Nucleo board.  Imported an example into ICE/IDE, compiled, linked, downloaded and ran. Just used MX to build my application based on the Nucleo board.  Compiled and linked.  Execute debug session and received this error, see attached.  I checked “Debug Configuration” and see nothing unusual. What has changed?  How I fix this problem?   

We have recently designed and implemented a PCB with TS4436 IC. And we are using this IC as a comparator in our application.While testing, we have observed that the IC taking near 40mA as supply current during OUT enable time (for FB input > 0.6V). But as per datasheet it won't take more than 4mA. We request you to go through the issue and share the resolution asap.  Sharing our application schematic for reference.  

I have the nucleo board connected to the STLINK-V3PWR via JP2 and ground connections. Flashed onto the device I have a mioty evaluation stack from LZE. I am taking readings of the current drawn and getting a consistent value of 3mA. I was trying to evaluate the deepstop current so wanted to know if the fact is that I have got my measurements/ connections wrong or that the firmware is preventing me from entering the mode. 

STM32H7 series MCU package version: V1.13.0SPI4 clock is selected as PCLK2, but in the actual generated project, the SPI4 initialization function incorrectly sets RCC_SPI45CLKSOURCE_D2PCLK1 instead. The clock tree diagram and code snippet are shown below.

STM32CubeIDE 1.19.0STM32C092GCU7 with 256kb flash, 128 pages with 2kb size I have 106,25KB of code. If I shift the start adress from 0x8000000 to 0x800A000 (to reserve space for future bootloader) CubeIDE cuts of the code to 88KB and only erases the pages till page 63 (Code would use now space in the second part of flash). Length in linker file is sufficient.If I take the generated .elf file and program it by STM32CubeProgrammer, everything goes well. But this is only a part solution for me, because I want to have the possibility to debug in CubeIDE. Start adress 0x8000000ST-LINK SN : 57FF6F067186535436441487ST-LINK FW : V2J46S7Board : --Voltage : 3.22VSWD freq : 4000 KHzConnect mode: Under ResetReset mode : Hardware resetDevice ID : 0x44DRevision ID : Rev ADevice name : STM32C09xFlash size : 256 KBytesDevice type : MCUDevice CPU : Cortex-M0+BL Version : 0x121Opening and parsing file: ST-LINK_GDB_server_a12268.srecMemory Programming ...

 Hello ST Community,I am considering using the High-Resolution Timer (HRTIM) on the STM32G4 series (specifically STM32G4x4 / G474) and would like to ask a few technical questions regarding its Input Capture functionality:1. Is my understanding correct that the 184 ps high-resolution feature applies mainly to PWM generation (using DLL), while the Input Capture function operates at the base HRTIM clock frequency (up to 170 MHz, giving ~5.88 ns resolution)?2. Is it possible to capture the timer counter values using the HRTIM capture units (CPT1 / CPT2) triggered by External Events (EEV) or internal signals (such as comparator outputs)?3. If Q2 is yes, does capturing via internal signals (e.g., comparator) yield the same measurement resolution (~5.88 ns based on 170 MHz) as capturing via external pins?Any clarification would be greatly appreciated. Thank you in advance!

 I am an STM32 developer.I recently started studying AI, but unfortunately, I discovered that there is no version of STM32Cube AI Studio for Mac. The same applies to Edge AI Studio. Are there any plans to release a version for Mac?

Also, Figure 241, 242, 243, 244, 245, Table 125.This section, figures and table all contain 17 references to ITEVFEN bit, supposedly from I2_CR2 control register.In reality, there is no such bit in this register, the actual name is ITEVTEN (interrupt event enable), and it is located in I2C_CR2, bit 9.Section 27.6.2 has correct name.stm32f405xx.h file, and others related to i2c, use the correct name: #define I2C_CR2_ITEVTEN_Pos (9U) #define I2C_CR2_ITEVTEN_Msk (0x1UL << I2C_CR2_ITEVTEN_Pos) /*!< 0x00000200 */ #define I2C_CR2_ITEVTEN I2C_CR2_ITEVTEN_Msk /*!<Event Interrupt Enable */Therefore, the ITEVFEN in the document should be repla

I am really very new to wireless communication but i need to make the project up and working. I have purchased 2 Wio E5 boards, getting confused how to build and make it working. I have gone through two gitshubs STM Repository and the seed studio repository  seedrepository At present i am looking for point to point communication. I found similarities with both the projects for example BSP folders for nucleo and LoraE5mini, i understand is i have to port the code, i tried hard but it is showing compilation errors. Please recommend me how do i proceed in terms of compilation.

Hi ST,Today I decided to give STM32CubeIDE for VS Code another try.I installed all 15 latest packages (Rev. 3.10).Using the STM32Cube Bundle Manager, I installed all required bundles, including Ninja 1.13.2.After opening in VS Code the folder containing the code generated by STM32CubeMX (CMake option) and trying to configure CMake for the first time (Ctrl+Shift+P → CMake: Configure), I received the error below.What am I missing? The last time I tried this several months ago, the project at least configured correctly and built successfully. Kind regards,Thomas [main] Configuring project: Firmware[driver] NOTE: You are configuring with preset Debug, but there are some overrides being applied from your VS Code settings.[proc] Executing command: "C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin\cmake.exe" -DCMAKE_BUILD_TYPE=Debug -DCMAKE_TOOLCHAIN_FILE=C:/Projects/All-purpose-Micro-Controller-2/Firmware/cmake/gcc-arm-none

STM32CubeIDEI have Project Directory (Fully populated from an earlier version of the IDE on a different machine)that I bundled up and then unwrapped on my new build machine.However, when I point my newly installed (up to date) IDE to my unwrapped Project directory,it “sees” the Project is there...but when I click “Finish” to bring it into my IDE, the IDE showsthe project (with the correct name) but devoid of any project properties...and no Source Code Tree(where I normally--and previously--could navigate all the source files).  I can see all the expected source code files in my Project DirectoryWhat is the disconnect?Do I need to manually edit the PROJECT.ioc or .project file (or .cproject or .settings or *something*) ?Is there a known issue with transferring a Project from an earlier version of the IDE?Guidance Appreciated!Paul++ 

Hello,We have designed a custom RF module based on the STM32WL33, and one of ourcustomers is asking us to demonstrate that the RX sensitivity of our modulematches the values published in the datasheet:  - RX sensitivity @ 1% BER:      -132 dBm @ 300 bit/s, 433 MHz, OOK      -128 dBm @ 300 bit/s, 868 MHz, 2(G)FSK      -112 dBm @ 38.4 kbit/s, 868 MHz, 2(G)FSKTo validate this, we would like to reproduce the exact test conditions usingan official ST development board (e.g. NUCLEO-WL33) and theSTM32WL33 GUI, so the result is directly comparable to thedatasheet.In the GUI's "Radio settings" tab we can set: fc, DR (ksps), Fdev (kHz),CHF (channel filter bandwidth, kHz), modulation (OOK/2(G)FSK/4(G)FSK/ASK),Spread Factor, and Pout.Could you please help us with the following:1. What DR / Fdev / CHF / Spread Factor values did ST use internally to   characterize each of the three sensitivity points above? In particular:     - For -132 dBm @ 300 bit/s / 433 MHz / OOK: Under the test conditions of 1

Hello! I installed the extension and configured it to work through a proxy (downloading the compiler, etc.), and everything works fine, but when I try to download devices list via cube pack sync, I get the error: Failed to download with Unsupported `GLOBAL_AGENT.HTTP_PROXY` configuration value: URL protocol must be "http:" I tried adding the proxy via platform environment variables, but that didn't help.

Dear Community,I am currently following the official MEMS Studio tutorial "Module 5 - MLC Configuration and Visualization" available on YouTube.I am using the following hardware and software setup:MEMS Studio version: 2.4.0 Board: NUCLEO-F401RE with X-NUCLEO-IKS4A1I was able to successfully complete all tutorial steps up to the Automatic Filter & Feature Selection (AFS) stage. However, whenever I click "Run" in the AFS tool, MEMS Studio displays the following error message:"Unexpected error with code 104 occurred during AFS request processing."The issue occurs consistently, even though I am following the tutorial exactly as shown in the video.Additional information:The PC has internet access. I tested both my company network and a mobile hotspot, but the error persists in both cases. No firewall events indicating blocked connections were detected. The board is correctly recognized by MEMS Studio and all previous steps work as expected.Could you please help me identify the cause of

Hi,I struggled a while to find out why my STM8S I2C was always “Busy”.Even AI had some headaches (except only one put me on the track ...)This device requires to configure the definition of I2C pinout in special FLASH.To do this, compile your project and open ST Visual Programmer.Load your “My_project.s19” file. There are three TABS in the window: PROGRAM MEMORY, DATA MEMRORY and OPTION BYTE. Click on option byte, select AFR6 and change it for “I2C SDA SCK” instead of “AIN4 AIN5”. Save your “My_project.s19” file.When your will burn the device, it will write the new parameters in the FLASH and the device will always be configured for I2C. You do this exercise only once.Hope it will help ….

The test conditions of VINCL parameters of VNS3V04DPTR-E chip are: Does light inject 1mA current into the IN pin, and does the SOURCE pin need to be grounded?

The magnetometer doesn’t start over I2C and doesn’t output data via UART. Please help solve the problem; the files are attached.

I recently purchased the STEVAL-LLL001V1 evaluation board, which uses the STLED524 LED driver. According to the user manual (UM2143), the board requires the software STLED524_V1.44.exe (or a later version) for operation. However, I have been unable to locate this software.Could you please let me know where I can download it?

I have a custom design with STM32mp135f + MT41K256M16TW-107 DDR3L @ 533MHz that I want to bring up. I built a Linux image based on OpenSTLinux guides and it boots until my kernel is loaded (uboot logs : “starting kernel”) then its crashes without any logs even with earlycon. By testing the DDR with ST DDR Tool, I realized that byte-masked writes fail (test 9), but halfword & RMW32 work.  I noticed the byte lane swap but it is identical on the dk board. I am a bit lost and don’t know if the issue is timing/config related or due to my hardware design.  

Good morning,I'm working on some new automotive designs and on the current boards i found what are , presumibly, STM components but i can't really identify them with the offerings in the online catalogs, (at least IF they are STM engineering samples)The body is specifically PowerSSO-16 but the marking of the components i found for now present similar but very different top markings2HTS90 D1B1HTS20 D11HTS10 200U2HTS30 D1B1HTS50 D1(these 5 are the ones i classified so far) Can i have some help in documenting them, if they indeed are VND productsBellow a picture of one of the components, there are all the same except the top markings (no logos or such)  

Hello,We are designing a custom board using the STM32MP157FAC1 device. For programming and debugging, we are providing an STDC14 connector on our board and use the STLINK-V3SET debugger/programmer.As per AN5031 (Section 8.3.3), the recommended ESD protection device is ESDALC6V1W5. Snapshot is attached for kind reference.We have the following queries:Query 1:Can we use the HSP053-4M5 device instead of the ESDALC6V1W5 for ESD protection? We are already using the HSP053-4M5 to protect the data, clock, and command lines of the microSD card interface. Using the same device for the STDC14 interface would help us optimize the BOM.Query 2:Can we connect USART1_TX (PA9) and USART1_RX (PB15) of the STM32MP157FAC1 to Pin 14 (T_VCP_TX) and Pin 13 (T_VCP_RX), respectively, on the STDC14 connector for the STLINK-V3SET Virtual COM Port interface? Regards,PS
