STM32 MCUs Software development tools

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

When creating a new CMake-based project in STM32CubeMX, the "Toolchain Folder Location" field is auto-populated with the project folder path upon entering a project name. This behaviour is misleading because the field is intended (at least by its description) to specify the location of the actual toolchain binaries (e.g., GCC ARM) and it is unlikely that a toolchain is installed in a specific project folder.I have tried to understand what this is by consulting the User Manual UM1718 Revision 49, and there were two references that matched the text "toolchain folder", both of which provided no helpful guidance on what this is actually used for.This is pretty much the only reference that describes what this option is for, which basically tells you nothing but confirms the toolchain is located in the project folder by default.Steps to Reproduce:Launch STM32CubeMX.Select a target MCU (e.g., STM32C011F6Px).Choose CMake as the project type.Attempt to change the field before setting a valid pr

is there any way to suppress this error message I get every time I recompile my cmake project? Clang Language Server client: couldn't create connection to server.Source: STM32Cube clangd

HiMAC BOOK PRO is using apple silicon(arm), i downloaded STM32CubeCLT-mac, but it seems installation is not sucessful, maybe it because it's x86/amd64 version.Do ST have plan to release STM32CubeCLT apple silicon version? ThanksPeter 

Edit: fixed a typo -- paHellow! When i debugging an application with a pre-installed bootloader in the Keil environment, I used the following script:FUNC void DebugSetup (void) { // </h> SP = _RDWORD(0x08040800); // Setup Stack Pointer PC = _RDWORD(0x08040804); // Setup Program Counter _WDWORD(0xE000ED08, 0x08040800); // VTOR to Image Base } FUNC void OnResetExec(void) { DebugSetup(); } DebugSetup(); // Debugger Setupin vscode plugin i add to launch.json"preRunCommands": [ "set $sp = *(unsigned int *)0x08018000", "set $pc = *(unsigned int *)0x08018004", "set {unsigned int}0xE000ED08 = 0x08018000", ],And it works fine until I do a reset, is there a way to fix this?For example, something like "postRestartSessionCommands". 

Hi,I have NUCLEO-U083RC-B01. I attached X-NUCLEO-IKS5A1 to it. All jumpers are in default positions.In STM32CubeMX I enabled I2C1 with default values. In the main program I am trying to check the device readiness for MEMS sensors on the X-NUCLEO-IKS5A1, e.g, ISM330IS. HAL_I2C_IsDeviceReady returns HAL_ERROR.I tried to set the I2C1 GPIO configuration Pull-up but no success. The I2C Speed Mode is standard. I check the readiness by:HAL_StatusTypeDef status = HAL_I2C_IsDeviceReady(&hi2c1, ISM330IS_I2C_ADD_H, 3, 100); I am attaching my main file.Thank you in advance.

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? 

After generating C code for a CMake project, I'd like to use some existing code that I've developed elsewhere.Is there good information or guidance on how to do this properly?For example, should compile my code as a static library and bring it into my project? If so, what is the recommended way to do this (how do I ensure compatibility, etc)? Or should I just copy-paste the source code files and headers into the project?

I've been trying to run code from the external QSPI flash (MT25TL01G) and have gone through an extensive debugging process that ended with a hard lockup. Below is a detailed log of my steps.1.

Split from IDE Version 2.0.0 - why remove MX ? as this has nothing to do with that topicPinout view is bad also.In center of window useless hole with ST logo. Wastefull use of GUI area. 80% of area is gray hole in center or white hole at the borders.Much better to use table with pins info. In the table can be shown some usefull information in addition to pin name (type of pin, for example). Current design can be used as additional presentation.CubeMX design is created by managers wich have no undestanding of developer needs. 

Modern microcontrollers have a lot of perifhery. Several buses of different types.STM32 hardware has outgrown C. Too much complex perifhery to manage with procedural language.ST software is much behind of ST hardware. Look at any I2C or SPI open source C library. Any can be used with one device of some type only.In case of I2C there are lines like this in header:#define SSD1306_I2C_PORT hi2c1 #define SSD1306_I2C_ADDR (0x3C << 1)andextern I2C_HandleTypeDef SSD1306_I2C_PORT;in C file.If somebody need one device on differnt port or on different device address he have to edit source files of library.If somebody need more devices of the same type on different device addresses and/or on different ports, he have to throw away library and write own solution.It is not possible to get library and make something like this:i2c_device1 = create_i2c_device(port1, dev_adr1, params1...); i2c_device2 = create_i2c_device(port1, dev_adr2, params2...); i2c_device3 = create_i2c_device(port2,

Hi everyone,I’m working on an STM32CubeIDE project generated with CubeMX and I’m trying to integrate mbedTLS to run a TLS stack.Setup details:MCU: STM32U375Secure Element: STSAFE-A120IDE: STM32CubeIDE (v2.0.0)CubeMX (v6.16.1) used for project generationTarget IoT platform - AWS IoT CoreAfter generating the project with CubeMX, I see the following components:Middlewares/ST/STM32_CryptographicMiddlewares/ST/STSElibX-CUBE-STSE01/Target folder at the project rootHowever, I can’t find any option in CubeMX → Middleware to enable or add mbedTLS. From what I can tell, CubeMX doesn’t expose mbedTLS as a selectable middleware for this MCU / configuration.I’ve seen suggestions (including from Google AI) that mbedTLS needs to be added manually, for example by:Adding the mbedTLS source to Middlewares/Third_Party/mbedtlsUpdating include paths and compiler symbolsConfiguring mbedtls_config.hPotentially hooking mbedTLS crypto callbacks to the STM32 cryptographic drivers or STSAFE servicesMy questions:

Heyho,I had some really strange error, which went away when turning optimization from "fast" to "off".The function EthPhyInit() always returned 166 = 0xA6 - it should return "HAL_StatusTypeDef", something between 0 .. 3.So I changed all the return values to some integer between 1..8 to find out where things go wrong, then added the last line:uart_printf("EthPhyInit() good ->return 0\n\r");before returning 0 when all went well.Still, always got 166 back, even when I got "EthPhyInit() good ->return 0\n\r" on the terminal.Until I turned optimization OFF, now all is good.WTF is happening there? Can optimization be that bad? /* +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ */ /** * @brief all PHY, ETH MAC & DMA reset and init: * 1) EthBaseInit() GPIO, clocks, basic stuff * 2) EthPhyInit() PHY * 3) EthMacInit() MAC registers * 4) EthDmaInit() DMA registers * @PAram - * @retval HAL status */ uint8_t EthAllInit(ui

Hello ST Community,I am facing a complete breakdown of my development environment with my STM32F407G-DISC1 board. I am dealing with three critical issues: a persistent debugging failure, the sudden disappearance of CubeMX from my PC, and an inability to download any installers from st.com to fix it.Here is the detailed situation:1. The Debugging/Flashing Issue I am powering the board via USB only and have been careful not to cause any power conflicts. However, I suddenly cannot flash or debug any code.* Error: "Error finishing flash operation" (using ST-LINK GDB Server).* Behavior: The ST-Link is detected, but the write operation fails immediately.* Steps Taken:* I tried changing the Reset Behaviour to "Connect Under Reset".* I tried holding the hardware Reset (Black) button manually while connecting.* I updated the ST-Link Firmware on the board (Update was successful).* I attempted a "Full Chip Erase" with STM32CubeProgrammer, but it also fails to communicate properly with the ta

Hello, Using controller: STM32F767BIT6 External SRAM: SRAM-1x16M-48TSOPI Interface SRAM via FMC is successful, currently using heap_4 and tried to work with moving variables & complete heap to external SRAM and it works. But I want to use external RAM as extended RAM if internal RAM get exhaust. I have seen some examples in Keil which allow to do the same by using .ANY .ANY (+RW +ZI)  So, this will allow to use runtime RAM if it is free, so just for thoughts, if I define .ANY in internal and external RAM then in runtime it will decide where to go based the available size. But in STM32CubeIde, not sure how it can be done. So, I need help or examples to understand how we can actually use external SRAM as extended RAM. Thanks, Nitin

stm32cubeclt一直安装不了，明明安装路径没有中文，就是安装失败。   Edit by ST Moderator (Here is the translation of your post): The STM32CubeCTL simply won't install. Despite the installation path containing no Chinese characters, it still fails.

I used version 6.14 beforeand could choose OrCAD's package There is no option for "Cadence" in version 6.16.1

I have four quite mature projects which I have developed with STM32CubeIDE 1.19.0 so far. Now I tested these projects with STM32Cube for VS Code using both toolchains.My environment:Debian TrixieVS Code 1.108.2  STM32CubeMX 6.16.1STM32CubeIDE for Visual Studio Code 3.7.0 fresh installed with all STM-Extension Packs and the following bundles in the project (from .settings/bundles.store.json): "name": "cmake", "version": "4.0.1+st.3" "name": "ninja", "version": "1.13.1+st.1" "name": "gnu-tools-for-stm32", "version": "14.3.1+st.2" "name": "st-arm-clangd", "version": "19.1.2+st.3" "name": "programmer", "version": "2.21.0" "name": "stlink-gdbserver", "version": "7.12.0+st.2" "name": "st-arm-clang", "version": "19.1.6+st.10" "name": "st-arm-clang-hybrid", "version": "19.1.6+st.3" I only used the release configuration and flashed the devices either with ST-Link or USB using the bundled programmer.I set up the project as follows:Generate a

I have a project that builds with no errors but when I "Run as..." the project builds but  never enters the upload sequence so doesn't upload.The board in question is a Nucleo F411RE & is communicating fine over UART. A previously loaded project is still sending out its debug messages, so I know the USB is good.Debug is not playing either... 

I am facing an issue with STM32CubeIDE installation where the “STM32 Project” option and CubeMX functionality are missing even after downloading the latest STM32CubeIDE package from the official ST website, extracting the ZIP file, and running the installer as administrator. The IDE opens successfully, but essential features such as MCU/Board selection, CubeMX integration, and embedded software package management are not available, which prevents me from creating a standard STM32 project. I have already tried reinstalling the IDE, but the problem persists. I would appreciate guidance from the community on the correct installation procedure or any additional steps required to enable full STM32CubeIDE and CubeMX support on Windows. 

I'm trying to use dual layers in LTDC of STM32N657X0HxQ controller. In the STM32CubeMX, I tried to set the Secure bit of RISUP for LTDC_L2 in RIF setting view, but the box is in gray color and is not selectable as follows.When I generate code with this box unchecked, my program does not work. So I manually changed the Secure bit in source code, which made LCD display work fine.How can I change the Secure checkbox in STM32CubeMX?My STM32CubeMX is version 6.16.1 for Windows 11.I've attached the ioc file.

Code generated by CubeMX use Windows line-endings, which generate huge problems under other operating systems (repository, editors, etc.). You have to strip CR-LFs after every code generation.Somebody should use standard method of platform-independent text file generation (StringBuffer and System.lineSeparator()).

Hi All,GreetingsWe are using STM32U585 on custom board with Trust zone enabled and now facing a connection issue with stm cube programmer in hotplug mode, now unable to connect to the microcontroller and getting ST-LINK error  as : DEV_TARGET_CMD_ERROR.When NRST is low continuously(pressing the Reset Switch) the connection to the controller through Cube Programmer is happening, but we are unable to change any option bytes, to revert back to Non Trust Zone Code. Once the reset switch(NRST) is high, it is going back to the same error. Any suggestions for this issue and how can we resolve this?Thanks and RegardsPhilip  

STM32CubeMX standalone hangs on File → New Project (infinite loading, no error message). The problem is fully reproducible.I have tried:– reinstalling CubeMX– different CubeMX versions– Java reinstall– offline mode– clearing STM32CubeMX cache/AppData STM32CubeIDE (latest) works normally but I can not generate projects with CubeMX. OS: Windows 11 pro Has anyone experienced this issue recently or knows a workaround / fix?Any advice from ST would be appreciated.
