STM32CubeIDE (MCUs)

Created a number of files in your glorious new IDE.After opening and closing a few projects in at attempt to find a hidden menu option, I can now see my .project files in finder but attempting to open them with the IDE via double clicking shows NO project data, just a blank space where the explorer should be.Is this a design 'quirk' with an odd workaround where I can recover the file somehow?is it an issue with V2.0.0 which needs resolving?Or is it just an inevitable fact of dealing with this buggy rubbish software?I actually wouldn't have minded MX moving to a different platform if it was designed to move the whole stack away from this eclipse junk, but I don't understand why you'd expend effort making IDE and MX less usable whilst not bothering to do anything about the buggy or just plain weird behaviour of the IDE

Lost links and routes, errors after migrating; etc... I reverted to 1.19.0 and 6.14 respectively   

I enabled the RTC wakeup interrupt in STM32cubeIDE graphical configer. The IDE added code to the MX_RTC_Init(void) which enables the interrupt and starts the timer. It’s the call to HAL_RTCEx_SetWakeUpTimer_IT(…) , and it’s not in the USER CODE block. /** Enable the WakeUp */ if (HAL_RTCEx_SetWakeUpTimer_IT(&hrtc, 0x1000, RTC_WAKEUPCLOCK_RTCCLK_DIV16) != HAL_OK) { Error_Handler(); } /* USER CODE BEGIN RTC_Init 2 */ /* USER CODE END RTC_Init 2 */I’m concerned that RTC interrupt may interfere with my own initialization, so I’d start the timer from my main() at a much later stage. I can call HAL_RTCEx_DeactivateWakeUpTimer(…) in the USER CODE to disable the timer. But is there graphical config – is there the Cube way – to tell the IDE not to add the HAL_RTCEx_SetWakeUpTimer_IT(…) call to MX_RTC_Init(void) ?[I’m using the graphical configer in the IDE and the MX interchangeably. But if the standalone MX has better options, please let me know. ]

I've done a fresh install of STM32CubeIDE on my Win11 computer. (Version: 2.0.0 Build: 26820_20251114_1348 UTC). I installed CubeMX through Help > Install New Software and then tried to open an existing projects .ioc file. This did not work, I got the following error (log also attached)The ioc file itself is fine. I can open it on other computers without a problem.I tried installing CubeMX as a seperate program, which works fine. I assume its the CubeIDE plugin that has a problem

 please give me some advice to fix it. Thank you. 

I made a new project by importing an .ioc file. When the project opened/created, I was introduced into pinout view of the MCU.While I was there, the software (Stm32CubeIDE) got updated, asked me to restart to finish the update.I accept the restart.After the restart, I open my projectIf I double click my .ioc file, it just opens the file with txt editor:I do not know how to enter pinout view again.Obviously, I have tried looking on all the tabs/options, right clicking everywhere. It should be something easy, I just missed it.STM32CubeIDE Version: 2.0.0 Build: 26820_20251114_1348 (UTC) (C) 2025 STMicroelectronics ALL RIGHTS RESERVED 

Hello,It's been two years since version 1.14.1 (everything was fine there) – is it really that hard to remove these white scrollbars? It's impossible to use STM32CubeIDE...BR

Hi,From yesterday, after selecting the example firmware for STM32WBA55G-DK1, in the final step of the process, the new warning is coming, saying "failed to perform local copy ". Kindly help me to resolve this issue.Thank You. 

I am new to STM cube ide. I was searching for the beginner friendly steps for this IDE.But unfortunately, the available tutorials are for previous versionHow do I get started to this?Do I install the older version?

Hello colleagues.My first post here...I have seen somewhere in youtube tha it is possible to provide URL to the specific Github location and use code from there as a library or some sort of included component. It has to be special file in Github serving as a "link" or index. Unfortunately, I forgot where I hve seen that and cannot find way to do that.  Any pointers ? Thanks.

I'm trying to find the cause of a hard fault in my code. The problem repeatedly appears after a few or more minutes after starting the  code, sometimes not at all, sometimes every time at close startup after enabling interrupts, and somethimes after a few seconds, as if it were dependent on the compilation. Somethimes watchdog re-runs code.CubeIDE, STM32G0 I tried debugger IDE and here apears something like this:   What does mean signal handler FFFFFFF1 and FFFFFF9 ? Maybe it helps me to find the problem.I dont use freertos, I dont use dynamic memory allocations. Only interrupts with 4 priority levels_Min_Heap_Size = 0x1000 ; /* required amount of heap */_Min_Stack_Size = 0x2000 ; /* required amount of stack */   

Hi ST Team,I am working on the STM32F746G-DISCO board.I have ported ThreadX with TouchGFX to this board, and I want to use the ThreadX + TouchGFX sources generated by STM32CubeIDE.However, I am facing build errors during compilation.Please find the attached photos/screenshots of the errors.I request your support in resolving this issue.If possible, please share any relevant documentation, guides, or reference links that explain how to properly integrate ThreadX with TouchGFX on this board.Thank you,

Hi! I have Linux Mint 22.2. How can I configure CubeIDE colors so that all windows have a white background? Various combinations of Windows->General->Appearance settings allow you to achieve a maximum white background for all windows except the one where you edit the code.Version CubeIDE 2.2.0

HiDeleted all my first attempts, wanted a new clean start.Then imported the "Templates" part of the ST provided "stm32cubec0-v1-4-0" examples.But it won't run nor build (greyed out).It says "The selection cannot be launched, and there are no recent lauches" (See attached)I've been looking through to make one but with no luck.The built in Help is not providing anything.

I know this sounds super nitpicky, but the app icon on macOS is not sized per Apple's human interface guidelines.Can you fix the app icon on macOS so it looks like all other macOS apps?Thanks!

I've been beating my head for a while trying to use OpenOCD to download my program to the chip, and I'm getting error messages which cite a write algorithm error (errors attached below). I'm not really too sure what I'm doing wrong, and would greatly appreciate any help and insight with resolving this!TL;DR. I'm getting errors likeError: flash write algorithm aborted by target Error: error executing stm32l4 flash write algorithm Error: flash write failed = 00000088 Error: block write failed Error: error writing to flash at address 0x08000000 at offset 0x00000000in the Console log from OpenOCD.I've reproduced the error using OpenOCD with STM32CubeIDE as follows where I set up a fresh project, demonstrate that using ST-LINK (ST-LINK GDB SERVER) works, and finally demonstrate that using OpenOCD fails.I create a new project withFile > New > STM32 ProjectAnd go to "Board Selector", then select the "Commercial Part Number" to NUCLEO-U575ZI-Q.I press "Next >", then fill out the

Hello,I moved an existing project from 1.14 to 2.0.0. To be clear I created a new workspace, then a new project in 2.0.0 in order to prevent any non relevant bit taken from 1.14 (at the project level) and copied only the source files from 1.14 to 2.0.0. The linker file comes from 2.0.0, as well as the startup file (which is not relevant here).When I compile I get the error that elf has LOAD segment with RWX permissions. The linker file has the READONLY moniker where they are needed, but I have 3 functions that are running from RAM, with __attribute__ ((section(".RamFunc"))). Obviously these are executables, so it is expected to have RWX in the .data section, where .RamFunc resides.How can I get rid of this warning, please ?Even though it is not relevant, the MCU is an STM32G0B1CB.

Did you find STM32CubeIDE will eat your perfect code when you doze off a while(put into system code segment). Hello,I have a suggestion: I hope STM32CubeIDE can put the deleted code segments into a backup file when user click "Generate Code" button. because sometimes user will wrongly put his code into system Generate code area, or someone can edit the configuration file(*.ioc) to disable the "global interrupt"(for example), this will lead to the interrupt service function codes to be overwritten or lost.sometime, it costs a lot. Second,If I can say freely, there will some wired things happen in the STM32CubeIDE, when I debug an "uint16_t" variable(like: Azimuth, in the blew picture), the value displayed can be a "-3"? I think this should be a bug.   

When I change variables from live expression and other areas during Prohe debug, I get the error "Failed to read all registers from target" and unfortunately I couldn't find a solution. I am using the latest version of stm32cube 1.18.1. There was no such jata before!  I am using Stm32f767zi processor. I tried with both st link v2 and isol version but this error is not resolved.
