Hi,I use STM32CubeMX v6.13.0 to generate a CMake project for STM32U5 devices. While code generation the process aborts with following error message:"The Code is successfully generated under: /home/user/projects/stm32u5_firmware Project language : C but CMakeproject generation have a problem." After looking in the generated CMake files, I spot various template artifacts:  cmake_minimum_required(VERSION 3.22) project(stm32cubemx) add_library(stm32cubemx INTERFACE) {{sr:Enable_CMake_lanuages}} target_compile_definitions(stm32cubemx INTERFACE{{sr:symbols_c_SYMB}} $<$<CONFIG:Debug>:DEBUG> ) target_include_directories(stm32cubemx INTERFACE{{sr:include_c_DIRS}} ) target_sources(stm32cubemx INTERFACE{{sr:sources_SRCS}} ) target_link_directories(stm32cubemx INTERFACE{{sr:link_DIRS}} ) target_link_libraries(stm32cubemx INTERFACE{{sr:link_LIBS}} ) # Validate that STM32CubeMX code is compatible with C standard if(CMAKE_C_STANDARD LESS 11) message(ERROR "Generat

My code gets complied without any errors. But just before the uploading completes: <signal handler> called at 0xfffffff9 is displayed.Even though after that my code runs properly without any hardfault.

Hello,I am currently using a F4 processor in HAL together with the Stm32cubeIDE.Thus the IDE generates F4 hal files which later are included in the main program.  To access the specific functions I need to #include "stm32f4xx_hal.h" in my own programs and libraries to make the HAL available in my programs.  When I later want to change the platform to an F7 processor I would need to change all the code to #include "stm32f7xx_hal.h". This is very inconvenient. How can I avoid this problem? Thanks in advance Alexander 

Title edited for length - please keep titles short, but descriptive.Original title: "SPI callback interrupt does not work for SPI, but works if I switch to other SPI with identical settings, same for timers and other peripherals"Hello,There I have problem with callbacks, not only with SPI, but at this moment trying to solve there, I use SPI5 for communicate with sensor, worked well until I changed some completely unrelated settings elsewhere in cubeMX, after code generation I found what I do not getting data from sensor, in my code SPI DMA transfer was initiated by timer callback, timer simply calls HAL_SPI_Receive_DMA function at specified intervals, I noticed what timer stopped to work, I tryed change, disable, remove, clean, delete debug folder, add timer to config again - without success, then I switched to another timer and with this timer interrupts started to work again ! Next - SPI5, there is the same - clean, remove, delete... without any success, then I switched to anoth

Translated content. 我在cubemx中同时使能usart1和usb发现有个警告 I enabled usart1 and usb in cubemx and found a warning usart1的流控被usb的dp和dm复用，但是实际上我是没有开流控的 The flow control of usart1 is multiplexed by dp and dm of usb, but I actually didn't turn on the flow control   为什么同时使用usb虚拟串口和usart1收发数据的时候，发现只要usart1一发送数据，两个串口都没有输出了？？ 这是为什么呢 Why when using the USB virtual serial port and usart1 to send and receive data at the same time, I find that as soon as usart1 sends data, both serial ports have no output? ? Why is this?

Hi, after doing a full chip erase over a device with a STM32F103, it's impossible to download a new version over DFU with the STM32CubeProgrammer. After I press connect it shows up corrupted data on the Manuf. ID, Product ID and Serial Number parametres, and when I tried to download the firmware it threw an error.The program crash if I press to many times the USB refresh button and If I press programming a few times. We change a few things related to memory on the device and I guess we messed up with something but I don't know how to recover the MCU after this. RegardsRafa

Can I use Nexus as proxy server for STM32CubeIDE & STM32CubeMX?What is URL of ST repository?Any experience of proxy server is welcome, thanks

When you change  for example the clock in .ioc (like from 48 MHz to 20 MHz) and even change it back to 48 MHz, your display stops working properly (colors not showing). TFT st7789v display and stm32h753vit6 microcontroller please solve my issue.

I'm using the STM32F405RGT6 board in a controller project. I wanted to use PA0 as PWM and PA1 as RX. For some reason, when configuring the .ioc, even though I configure UART4 as receiver only, it doesn't allow me to use PA0 as PWM. Is there any other way to configure this in the code?

I don't see the wrapper listed in the package for H5 although its listed in this documenten.stm32h5-cube-firmware.pdfwhere can I get it? Is it possible to download and add the package to STM32CubeMX?

We are having a similar issue as this person here:https://community.st.com/t5/stm32cubemx-mcus/why-does-the-ioc-file-show-warnings-on-disabled-peripherals/m-p/144500/highlight/true#M5600One of the responses was that this is just a warning message and is okay.  But I think this is causing us to have an issue with using a CICD pipeline to handle project generation. When I use a build script with project generate I would expect the whole process to be done without interacting with the GUI but an empty warning message actually comes up for me to click 'yes' to before it will go any further.  I tried an .ioc file that I found online to test to see if it would also generate this error and it does not.   I am hoping there is a way to bypass any warnings generated when doing the build using a script. Any help is very appreciated.

When I generate a new project in CubeMx 5.3.0 for the STM32H745I-DISCO board for IAR toolchain, I get the following code:HAL_PWREx_ConfigSupply(PWR_LDO_SUPPLY);The example projects in CubeH7 package use this code instead:HAL_PWREx_ConfigSupply(PWR_DIRECT_SMPS_SUPPLY);With the code generated by CubeMx, when I unplug the USB cable (which supplies power to the board) from the STLK port, plugging it back in causes the code not to run.With the code from the examples, the code runs ok.I believe the code generated by CubeMx misconfigures the FW for the STM32H745I-DISCO board.Anyone else have this issue?

Hi,I followed exactly the instructions of ST's youtube tutorial "Get started with STM32Cube for VS Code: from installation to debugging". (https://www.youtube.com/watch?v=aWMni01XGeI)Everything went perfect, the demo builds without problems.When it comes to debugging, VS Code gives me the error "Failed to install missing pack. "STMicroelectronics.stm32u3xx_dfp.1.0.0"Additional the is the same error as extension notification, see below.I tried Ctrl+Shift+P + Restore STM32Cube CMake projects configuration, but to no avail.Same thing happens with other STM32 CMake projects.What did I miss? Thank You in advance

STM32L052C8T3/ STM32CubeIDE:In search of the causes of excessive power consumption, I had the firmware compiled for release mode.

I have two stm32f429 Discovery boards. I programmed one of the board using cube ide; the output of which was as expected. Then using cube programmer I read and saved the bin file from that board. Using that bin file I programmed my another board which was successful, but there was no output.Is there any another method to do this?I am doing this because I want to save bin file from my custom board and program it to another board and I don't have original code.

I'm trying to configure BOR using STM32CubeProgrammer but I can't locate it on Option Byte. Even if I refer to RM0091 manual there's no section about BOR levels. 

Hello,I am experiencing the following issue and would appreciate your help in resolving it:When I create a new STM32 project for STM32G474CEU6 in STM32CubeIDE, main.c and other source files are not generated.The .ioc file loads correctly and the GUI opens as expected, but a message saying “Code generation could not be done..” appears, and only the BSD_License.ftl file is generated.When I press Alt+K to regenerate the code, only two files — common.ftl and mw_common.ftl — are added, and no error messages are shown.In the Problems tab of the IDE, a warning appears: “Project '*' has no explicit encoding set**”, but this can be resolved by pressing Ctrl+1. However, even after fixing this and regenerating the code, nothing changes.Under STWindow > Preferences > STM32Cube > Firmware Updater > Check Connection, a green check mark is displayed.This issue occurs only on an old Windows 11 laptop. On a newer Windows 11 machine and on Ubuntu, code generation works perfectly.I have tried

Hello,I am currently trying to convert my STM32CubeIDE (based on makefile) project to a STM32 VScode extension project based on CMake.Everything seemed to work smoothly until I was met with an issue calling the 'localtime' function from the standard 'time.h' class.This function has worked well so far in my CubeIDE project and I am using this to convert a uint32_t epoch to a tm struct.In my CMake project this fails by calling '_exit' and getting stuck there.The callstack is as follows:I am not sure what is the issue, is the standard library not implemented in the newlib of the CLT package?I tried looking at the 'gcc-arm-none-eabi.cmake' script and compare it to the makefile but none of the changes I tried making made any difference.Thanks.

I have set HAL_IncTick timer (tim6) to not interfere with systick when using thread and RTOS, the new callback was created by cubeMX and I got error about second declaration, I moved my timers settings to newly created callback, later I decided to change to tim18, after code upload I found what some functions do not work like expected, by debugging I found what everything what was in this callback is gone and there is newly created fresh callback just with newly created tim18 settings, everything else is gone ! CubeMX do not checks previously created callback by cubeMX and just deletes it ! 

It does it only on one PC out of several, however.More details here (EEVBLOG link, not dodgy, had to do this because this forum cuts pieces out of URLs to other forums)https://tinyurl.com/4r5uwt2s I've tried the Xmx1024m stmcubeide.ini file parameter, to 768m, which reduces (see above link) the memory used, but Cube still eats up all the physical memory.24GB RAM machine. 

When using HAL library, HAL_Init has init code:#if (INSTRUCTION_CACHE_ENABLE == 0U)__HAL_FLASH_INSTRUCTION_CACHE_DISABLE();#endif /* INSTRUCTION_CACHE_ENABLE */#if (PREFETCH_ENABLE != 0U)__HAL_FLASH_PREFETCH_BUFFER_ENABLE();#endif /* PREFETCH_ENABLE */ But when using ONLY LL library, these two settings are ignored. Enabling or disabling the two settings generates the same code. Please fix it.

Hello,I'm trying to run a ML model (miniresnet from modelzoo) to a NUCLEO-N627X0-Q starting from STM32CubeMX (initialization of device, model & code generation). Everything is OK when i select STM32Cube.AI MCU runtime, the model is created and runs smoothly, however, when i select STM32Cube.AI Neural-ART runtime (with n6-noextmem profile since i have various problems with external flash and the model is small enough to fit in SRAM) the code is generated fine, but an extra .raw file ([modelname]_atonbuf.AXISRAM5.raw) is created.I noticed the the compiled .bin file  (In STM32CubeIDE) is rather small (~62Kb) so i am pretty confident that it does not contain the full model (~122kb). I suspect that somehow i have to load this raw file to memory for the NPU to read.When i run the model through NPU the output is constantly zero (uninitialized or zeroed weights maybe?).I am using the nucleo in n DEV_BOOT Mode, do i need to load the raw file to memory manually? is there any guides

- Folder in projects shows no file (empty) when expanding.There are already files in project folders in path.
