STM32 MCUs Software development tools

Dear ST Support Team,We are using the STM32N657X0H3Q1 microcontroller with the XSPI1 interface and have connected two external memory devices, each with an 8-bit data bus.As described in the STM32N6 reference manual (XSPI dual-octal configuration), the two 8-bit memories are connected in parallel and together form a 16-bit wide external memory interface, sharing a single NCS signal.In STM32CubeMX, what we have configured the XSPI peripheral as attached below.And XSPI clock we set as 140mhz.Could you please confirm whether this STM32CubeMX configuration is correct? If there are any additional settings or recommended , kindly let us know.Thank you for your support.Best regards,siddu marka.

Not always, but sometimes syscalls.c file is removed upon generating code for X-CUBE-AI middleware.I'm using STM32N6570-DK board and the version of STM32CubeMX is 6.16.1 for Windows 11.

I downloaded CubeMX and I followed the instructions on the attached Readme.html.I run it by ctrl-click and then select Open to mark the author as trusted, but then nothing happens. Does anyone encountered the same problem? How did you solve it? 

MT tools is mess of Eclipse-RCP based tools (CubeIDE) and tools with hand-made GUI, whichresembles GUI of 90x (CubeMX, CubeProgrammer).Hand-made GUI applications has a lot of code which can be thrown out after switch to Eclipse RCP.Anyway, CubeMX is Java GUI application. CubeMX and CubeProgrammer has primitive Java GUIdeveloped from scratch.Instead of use a lot of existing functionality of Eclipse RCP, developers had to write own codeand invent a lot of wheels. It increase costs of development and maintanence.It is not much effort to move CubeMX functionality to Eclipse RCP application.A lot of code can be thrown away. It will decrease costs.With Eclipse 4 one can make GUI XML model with visual tool and make several simple adaptersto inject existing Java panels in corresponding model views.With such approach MX-relative perspectives can be used as standalone application and used withany IDE. And can be integrated in CubeIDE.It is very flexible solution. Current CubeMX is old monolithic

Hi Starting my first project testing VSCode integration of ST tools instead of using Eclipse... Just reporting an issue with build analyzer, it is indicating that I have 188% of FLASH used...The compiler output gives the correct information:It seems an issue parsing the map or elf file to operate the tool. 

Hello, I'm having trouble getting the CubeMX code generation to work reliably with X-CUBE-AI package.After first adding X-CUBE-AI to the project, and adding one of the models from the ST model zoo, i get this warning:If i click Yes, the code generation takes about 5 minutes and works.Note that in the above picture, X-CUBE-AI ExtMemLoader is selected. This is also where the warning comes from. AFAIK, i don't need X-CUBE-AI ExtMemLoader, just the Application. If i remove the checks from the checkboxes "Artificial Inteligence X-Cube-Ai" and "Device Appliccation", and then reopen MX, the X-CUBE-AI ExtMemLoader will disappear, and just the X-CUBE-AI Application remains. However, after trying to generate code with that setup, the code generation hangs to the below phase of code generation: At that state, the OpenJDK Platform binary uses over 6000 MB of RAM, and about 10% of my CPU but seemingly nothing happens. I waited over the weekend to see if the genera

Hi,I would like to report that STM32CubeIDE is freezing when running on Wayland session.The solution I found is to start Ubuntu in a X session.Best regards,Daniel

It is very inconvenient to have regenerated C files in C++ project.Problem is not main.c only, *_it.c as well. In C++ project one have to call methods of class from interrupt handlers.It is not possible to make directly from *_it.c. Indirect call chain is lost of time.I renamed main.c to main.cpp in C++ project, made call from main.cpp to method of class. All is OK.Flashed microcontroller with main.cpp, all is working.ST done great work to support C++. And made it useles by generating new code to C files. Why not to generate code in C++ project to CPP files? 

Hi,I have some CubeMX-generated code which works properly. Originally it was created to run from default address 0x08000000.Now I have a bootloader at address 0x08000000 which is responsible for handling updates and other stuff and then jumps into the target-code, so I moved that code via linker script to 0x08020000. This also works fine, the code works as desired.In a next step I decided to have some additional information stored in flash prior to the CubeMX generated code to make it easier for the bootloader to manage firmware versions, so I shifted the code by additional 128 bytes and now have the following section in my linker script:MEMORY { FLASH_BOOT (rx) : ORIGIN = 0x08000000, LENGTH = 128K FLASH (rx) : ORIGIN = 0x08020080, LENGTH = 1024K - 128K - 128 EEPROM_EMUL (xrw) : ORIGIN = 0x080E0000, LENGTH = 128K DTCMRAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K RAM_D1_DMA (xrw) : ORIGIN = 0x24000000, LENGTH = 64K RAM_D1 (xrw) : ORIGIN = 0x24010000, LENGTH = 320K - LEN

I am trying to use the gprof editor/viewer within cubeide but it doesn't work, everything just freezes then crashes with no error messages, i also found nothing in the logsI'm trying to use gprof profiling arm-none-eabi-gprof.exe, i have my code instrumented and got a valid gmon.out file, it is small ~15kb, the file is valid as i can process is manually with gprof.exe and get a textual representation of the profiling data.However i don't want text output, i want the included viewer in the cubeide, to see in a nice tree view the data, i have the option to open the gmon.out file with the gprof editor but when i do, it asks for the corresponding elf file then after that everything freezes then crash. What am i doing wrong? Is this expected to work at all? Did anyone use it?Cube ide1.18 stm32f429 discovery project

I'm trying to configure DMA in Memory-to-Peripheral mode for the STM32WB09KE, specifically to transfer data from memory to a Timer channel (TIM2_CH3 for Addressable LED's). However, in STM32CubeMX, I cannot see the expected DMA options under the DMA Settings tab for my Timer.    

With CubeIDE 1.x iterative development is simple1 Start CubeIDE and create new project. It is possible to select C++ project option at project start (without any effect)2 With Device Configuration Tool create initial perifery config. It is possible to open second windows for it and have two separate windows side by side. Generate code.3 Switch to first window and work with generated code4 If need new device, switcn to second window, add new device, config it and generate code.5 In first window regenerated code is created in sync with Configuration Tool. Convenient and logical steps. Great work!How iterative development can be done with CubeIDE 2.0?

# External Loader Issue: STM32U5G9ZJT6Q + MX25L12833FZNI-10G (Quad-SPI)## 1. Problem SummaryHello, I'm a novice developer who recently started working with embedded systems. I've been struggling significantly with implementing an external loader for several weeks now...I'm developing an external loader for **MX25L12833F** (16MB Quad-SPI NOR Flash) connected to **STM32U5G9ZJT6Q** via OCTOSPI1, but it continuously fails in STM32CubeProgrammer. The loader compiles successfully and generates a `.stldr` file, but programming operations fail.The problem is sector erase. Writing, reading, verification, and mass erase all function normally, but only sector erase does not work properly. What could be the reason? __attribute__((used)) int SectorErase(uint32_t EraseStartAddress, uint32_t EraseEndAddress) { OSPI_RegularCmdTypeDef sCommand; uint32_t SectorAddr; uint8_t status_before = 0; uint8_t status_after = 0; g_erase_input_start = EraseStartAddress; g_erase_input_end = EraseEndAddre

Can multiple versions of a software be installed on one computer or system? The latest version I recently downloaded doesn't include MX. Should I install version 1.19.0, or use the uninstallation method for version 2.0.0?

Hello all,I have been reading other posts with the same problem but I do not get the solution in my case.I'm using the development kit STM32F446RE (Nucleo 64).I have created a new project with STM32CubeMX 6.16.1, and I open the project with STM32CubeIDE 2.0.0. When compiling (in Debug or Release) I get this error: 11:39:26 **** Incremental Build of configuration Debug for project TEST_ST_NUCLEO ****make -j22 all make: stat: ../Core/Startup/startup_stm32f446retx.s: Permission deniedmake: *** No rule to make target '../Core/Startup/startup_stm32f446retx.s', needed by 'Core/Startup/startup_stm32f446retx.o'. Stop."make -j22 all" terminated with exit code 2. Build might be incomplete.11:39:27 Build Failed. 1 errors, 0 warnings. (took 584ms) Any help will be welcome. Thanks in advence.  

hello,now I am using stm32f030cct6 to design a simple program. i used all the 6 uarts of this chip. it works fine, but the interrupt code generated by STM32CubeMX has a simple bug. the code as below.for the uart6, there is a useless （&huart6);  i think it is no effect to the function, but when building, there is a warning.stm32f0xx_it.c:172:33: warning: statement with no effect [-Wunused-value][build]   172 |   HAL_UART_IRQHandler(&huart6);(&huart6);[build]       |                                ~^~~~~~~~ I dont like the warning. so i think you can simplly fix this bug. thanks.

Hi everyone,I am encountering an issue with the "Access to MCU Selector" feature.The Problem: After installing X-CUBE-AI packages version 10.2 (or any version later than 10.0), the MCU Selector fails to open. It gets stuck in an infinite loading loop. Additionally, the "Output" view remains empty, showing no error logs.Troubleshooting: I found that if I uninstall the versions newer than 10.0 and revert to X-CUBE-AI version 9.0.0, the MCU Selector works perfectly fine.Has anyone faced this issue? Is there a known workaround or solution to use the 10.2 version without breaking the MCU Selector?Thanks in advance. 

From cube 1.3.0 I always get this error and the cause seems to be the path generation in .d files. In cube 1.12.1 the path is relative but from cube 1.3.0 it is absolute and generates something like \\?\C:\.... So the only solution for me is to stay with cube 1.12.0. The build however seems ok an the bin file is generated. Did anyone had a similar issue? The issue is present only on windows and it seems ok on linux.arm-none-eabi-size STM32F769I_TEST.elfarm-none-eabi-objdump -h -S STM32F769I_TEST.elf > "STM32F769I_TEST.list"arm-none-eabi-objcopy -O ihex STM32F769I_TEST.elf "STM32F769I_TEST.hex"arm-none-eabi-objcopy -O binary STM32F769I_TEST.elf "STM32F769I_TEST.bin"text data bss dec hex filename1227608 43680 452264 1723552 1a4ca0 STM32F769I_TEST.elfFinished building: default.size.stdoutFinished building: STM32F769I_TEST.hexFinished building: STM32F769I_TEST.binFinished building: STM32F769I_TEST.listtest/web/unicabminnow.d:1: *** multiple target patterns.

I just installed CubeIDE 2.0.0 on Ubuntu 24.04 (finally!).  However I cannot launch it (I do get the initial workspace selection popup, but after selecting "Launch" I get this error):$ /opt/st/stm32cubeide_2.0.0/stm32cubeide_wayland Could not create GBM EGL display: EGL_NOT_INITIALIZED. Aborting...A little bit of poking around on Google suggests that installing libnvidia-egl-wayland1 should fix this issue, however on my system libnvidia-egl-wayland1 is already installed:$ dpkg -l | grep libnvidia-egl-wayland1ii libnvidia-egl-wayland1:amd64 1:1.1.13-1ubuntu0.1 amd64 Wayland EGL External Platform library -- shared libraryii libnvidia-egl-wayland1:i386 1:1.1.13-1ubuntu0.1 i386 Wayland EGL External Platform library -- shared library I have tried rebooting a couple of times but I keep getting the same error.  Does anyone know how to fix this?

SOMETIMES (not always), when i try to debug (and only when i try to debug, run does its job well) with STM32CubeIDE my Riverdi board, i encounter the "Could not verify ST device! Please verify that the last version of the GDB-server is used for the connection" error. It happens right afterLoading RTOS driver... ThreadXConnecting to GDB server 127.0.0.1 on port 61234 ... ConnectedListen for GDB connection on port: 60000 ... Connected.if this helps.Downloading code with run is always fine, and sometimes the debug option works, but not always. It is really annoying to rely on luck to make the *** thing work. I tried unplug-replug. The board is definitly not counterfeited, same goes for the ST-Link. 

I made a support pack for better support of CAN connections.But there is no possibility to create a "Platform Setting" for CAN connections I tried to edit the "Modes.xml" manually. Than the PackCreator shows the correct IP, but STM32CubeMX doesn't accept it.  Additional: if I create a not usable platform setting there will be "unsovlable" warning.

I am trying to build the basic LED Blink on the STM32-N6570-DK , since i have build the code and try to run with the default settings it ends up with the following problem , whats the reason and how to solve this ? 

Hello,how may I change font size for Live Expressions view?None of the options in General | Appearance | Colors and Fonts has effect. Alessandro

I select a new project and select the STM32L100C6U6A. STM32CubeMX says it has 4 kBytes of RAM.I generate the project for EWARM.But when I generate the project for EWARM it puts stm32l100xba_flash.icf file in the project and that files says RAM is 16384 bytes.And the datasheet for STM32L100C6U6A says 4 kByte.Is this a bug in STM32CubeMX?My application still seems to run without errors. IAR reports 9511 bytes of readwrite data memory used.Why does it still work? Is the datasheet wrong and this device is actually delivered with 16 kBytes RAM?
