STM32 MCUs Software development tools

Title edited from just "login" to identify which particular login is affected.I can't log in to my account through the program and I can't open code generation. Can you help me with this?

After updating and restarting my PC with Windows 10, my old version of CubeProgrammer would not open at all. The version number is unknown. Other STM32 software works without any issue such as CubeMX and CubeIDE.I then tried installing the latest version, 2.21.0. The program launched (even when run as administrator), but it did not function fully. I attached a screenshot for reference. None of the four icons on the top-left responded, and I received error messages when clicking the icons on the right.I also tried installing previous versions from 2.16.0 to 2.20.0, but none of them worked. Specifically:Versions 2.16.0, 2.18.0, and 2.19.0 briefly showed the launch logo, then closed immediately.Versions 2.20.0 and 2.21.0 would open, but the program remained unusable.

Hello,i have project with a'n STM32H743II on a custom board. I use a J-Link Plus to debug and download the program, everthing was working fine. When i updated to version 2.0.0  downloading the program elf file failed. After initialization sequence and downloading the first block the debugger stops, because it can't load the elf file, but the file exists and the path is correct. Message window:Debugger console output: SEGGER J-Link GDB Server V8.80 Command Line Version JLinkARM.dll V8.80 (DLL compiled Oct 22 202

When using the memory management tool (MMT) on the STM32H573 to set the backup RAM as secure it generates an invalid secure attribution unit (SAU) config:#define SAU_INIT_REGION5 1 #define SAU_INIT_START5 0x40000000 /* start address of SAU region 5 */ #define SAU_INIT_END5 0x400373FF /* end address of SAU region 5 */ #define SAU_INIT_NSC5 0The above code is the last region the MMT defines for the SAU.Typically the tool would define the region 0x40000000 to 0x4fffffff (the non-secure peripheral address space) as non-secure. However 0x40036400 is the start of the backup RAM address space which shouldn't be made non-secure.Since this is the last SAU region, there is nothing configuring the region 0x40037400 to 0x4fffffff as non-secure, and so hard faults occur when e.g. trying to access the non-secure RCC address space.I believe correctly generated code should look like the below:

I have installed the stm32 cube ide , after creating the project i am get .ioc file for the configuration , i have done reinstall process but i am unable to clear the issue , the ide is opened as the image attached . 

CubeMX version 6.16.1 I found STM32WBA55CG project with ThreadX,  the  parameter of "TX_LOW_POWER_USER_ENTER" and "TX_LOW_POWER_USER_EXIT" will be reset to default after the ioc re-open.This bug can be 100% reproduce. 

Hello,I have a question about vscode with STM32 extension. I have setup a project with vscode and stm32 extension, and after compiler, it can do debug, and I can see the Global Variables on the VARIABLES window. as belowbut when I use vscode to do another design not with stm32 extension. I do the debug, but I cannot see the Global Variables on the VARIABLES window. as below, only Locals and Registers.

Hello,I need to develop an external memory loader for a custom board with the STM32U375 and Macronix MX25U6432F NOR-Flash as external memory. The interface is via OCTOSPI1.I have already tested the interface functions to access the external memory and everything is working fine when used within a "normal" application running in the STM32U3 internal flash.As I am using the STM32CubeIDE, I created the code for the external memory loader based on the templates in https://github.com/STMicroelectronics/stm32-external-loader/tree/contrib. I am using STM32CubeIDE v 1.19.0 and STM Cube Programmer v 2.21.0.When I try to use the external loader in the CubeProgrammer, I can see (with some debugging) that the Init() function is called by STM Programmer, but fails quite early during HAL_Init(). With further debugging,

I created a new project using CubeMX, and after that I plan to implement a framework for my firmware. I would like to better understand the best way to organize a clean and maintainable folder structure.A colleague told me that all folders should be created inside the Core directory. I would like to understand whether using Core to contain my framework is the best approach, or if it is acceptable to create additional source folders outside of it.Additionally, where can I find examples of STM32 firmware projects generated using CubeMX?

Ports definition in main.h forced to include too mutch in dependend source files when one needs ports definition only.More convenient dedicated header file with ports definition only. Something like ports.h.It would be nice to have more layered structure.

i can't get to download stm32cubeide. download jus

Hello ST Community,I would like to report a potential discrepancy I have discovered between the pin definitions in STM32CubeMX and the official datasheet for the STM32N6 series, specifically concerning the Serial Wire Output (SWO) signal used for debugging (SWV/ITM). This issue led to a hardware design error on my part, and I believe it warrants clarification to prevent others from encountering the same problem.According to the STM32N647xx datasheet (and related family documents), the SWO function is assigned to Pin PB5, The TRACECLK function is assigned to Pin PB3However, within STM32CubeMX (I am using version 6.16.1)(N6 MCU package version 1.3.0), the graphical pinout view shows that Pin PB3 is also listed with the "DEBUG-JTDO-SWO" functionality. More importantly, when configuring the debug port in the "SYS" settings (e.g., selecting "Trace Asynchronous Sw

do the example of LPGPIO,why show this error.Getting started with LPBAM - stm32mcu 

I have just spoken with an ST sidekick, and I was informed that STM32CubeMX is currently not supported on Windows ARM64.Thank you for the clarification.  

I recently updated my stm32cubeide from 19 to 20.0.0 but the .ioc files of my existing projects open as text file not graphical as before. How to fix it to work as before? PS: I mistakenly chose VS-code target and it's not possible to delete the post and repost. I use STM32CubeIDE on Windows and my issue have nothing to do with vs-code (I don't use it whatsoever)   

I've tried this evening to download STM32CubeIDE on 2 different accounts, 2 different computers, a phone, and have reset my computer and also deleted my cookies but still will not download. Nothing happens after I accept the terms and conditions. I have also tried to download as a guest the link from the email still just takes me to the download page but it won't download.

Hi everyone,this is my first post, as I have always been able to solve my problems thanks to your help. Unfortunately, I can't find a solution regarding the CubeProgrammer API, which I am currently working on. I am developing an update tool that will use the internal bootloader of a STM32H743. For this, I am developing a C++ programm, using Visual Studio 2026 Version 18.2.0 with .Net Framework Version: 4.8.09221. CubeProgrammer_API.h and all neccessary .dll files are included as described in the documentation. There are no compiler errors or warnings. I used the attached UART example for testing but it is not possible to connect to my device. COM ports are detected by getUsartList function as expected. If I try to connect with function connectUsartBootloader as shown in the example I will get error -5 ( CUBEPROGRAMMER_ERROR_NOT_SUPPORTED ). Nevertheless, it is possible to establish a connection

I have a characteristic that supports write and indicate. A command is written to the char, the server responds by indicating the characteristic to the client. I'm using Stm32CubeMonitor-RF 2.19.0 to test the server, but indications always cause a ACI_GATT_PROC_TIMEOUT_EVENT because STM32CubeMonitor-RF does not issue a ACI_GATT_CONFIRM_INDICATION after an indication is received. log file attached. 

After installing under STM32Cube key actions, and all other headings, "There is no data provider registered that can provide view data." is displayed. I have tried adding the path to Cube MX. In the STM32Cube Core plugin, runtime status shows not yet activated. Manually activating does not work. Running on Windows 11 arm64.If I roll back to a version 2, everything seems to function, however I need version 3 working. Any suggestions?

Question moved from this post. Hi @mƎALLEm ,I am using STMCubeIDE with cubeMX, in that there is no such configuration for VREFBUF. is there any alternative way for that?

0I have a device with an MCU in DFU-mode, and I want to flash new firmware to it. To do that I have the software we have developed at my company to interact with the device, mainly a Wpf-application written in C# and Xaml, which in turn uses the KSociety SharpCubeProgrammer library to make calls to the STM32 CubeProgrammer_API.If I use the STLink V3 SET hardware over I2C I get a CubeprogrammerErrorWriteMem error (return value -10), i.e. a memory write error, but using the same firmware file but instead directly over USB, i.e. not using the STLink, I get no error and the firmware is updated. In either way the calling code is almost identical, and I have checked that the data and address is the same when calling the API over both I2C and USB. The method called from the API is in either way WriteMemoryAndVerify(...).I found some information saying that it's the STM32_Programmer_CLI.exe

Hi,if I connect the Cubeprogrammer via jlink to the custom board (STM32H562) and want to reset the option bytes by menu-selection "Reset MCU to factory settings", the process don't finish because the mentioned error pops-up.Is this caused due to a missing signal on the debug connector? The problem is now, that the mcu is in provisioning state and I want set it back to open state.Kindly regards,Stefan

On a Nucleo-H563ZI with CubeIDE 1.14.0 and firmware package for H5 1.1.1.I managed to get SPI transmit and receive using DMA, triggered by a timer, going not using linked lists. I get my requested number of transmissions and results into my buffers as witnessed on an oscilloscope and a live watchpoint.But when I enable circular mode, no other modifications, in MX_SPI1_Init - HAL_SPI_Init - HAL_SPI_MspInit it sets up NodeConfig.Init.SrcDataWidth = DMA_SRC_DATAWIDTH_WORD; NodeConfig.Init.DestDataWidth = DMA_DEST_DATAWIDTH_HALFWORD;builds the node (whatever that is), inserts it into the correct DMA channel, sets circular mode, basically looks like magic but I can imagine what it is doing. But then the stuff in the NodeConfig doesn't get applied to handle_GPDMA1_Channel1, so later w
