STM32CubeIDE (MCUs)

Hello all,I'm facing a wired issue. After the IDE update in the Help menu there is no more the entry to log-in in myST.Do you have any suggestion how to reach the myST login from it?I'm running the IDE on Windows. Thanks in advance!

I have been developing successfully with STM32CubeIDE for several years. My current project has been going ok, with lots of in-application debugging, until my latest revision. The debugger quits with the following error message:----------------------------------Error in final launch sequence:Failed to execute MI command:load C:\\Users\\feath\\OneDrive\\Documents\\Featherweight\\BlueRaven\\IDE_Workspace\\BlueRaven\\Debug\\BlueRaven.elf Error message from debugger back end:You can't do that when your target is `exec'Failed to execute MI command:load C:\\Users\\feath\\OneDrive\\Documents\\Featherweight\\BlueRaven\\IDE_Workspace\\BlueRaven\\Debug\\BlueRaven.elf Error message from debugger back end:You can't do that when your target is `exec'Failed to execute MI command:load C:\\Users\\feath\\OneDrive\\Documents\\Featherweight\\BlueRaven\\IDE_Workspace\\BlueRaven\\Debug\\BlueRaven.elf Error message from debugger back end:You can't do that when your target is `exec'You can't d

I have a simple function with loop that checks RX pin state for 10ms, and if there was high level - breaks loop and exits. it works ok with -O0, but is broken with -Os or -O1 (-O2) or -Og - it loops forever.Here's code:uint8_t isModemOn() { uint32_t expire = uwTick + 10; while (expire - uwTick < 11) { // check RXD pin level, if low for 10ms - consider modem is off if (LL_GPIO_ReadInputPort(GPIOA) & LL_GPIO_PIN_10) { return 1; } } return 0; }and how it's appears in listing080003dc <isModemOn>: * @PAram GPIOx GPIO Port * @retval Input data register value of port */ __STATIC_INLINE uint32_t LL_GPIO_ReadInputPort(GPIO_TypeDef *GPIOx) { return (uint32_t)(READ_REG(GPIOx->IDR)); 80003dc: 21a0 movs r1, #160 @ 0xa0 //#pragma GCC optimize ("O0") // Error in -Os optimization uint8_t isModemOn() { uint32_t expire = uwTick + 10; while (expire - uwTick < 11) { // check RXD pin level, if low for 10ms - consider modem is off if (LL_GPIO_ReadInputPort(GPIOA) & LL

Hello,recently I started a project based on a STM32L433RCT3 and the STM32CubeIDE build tooling defaults to C++14. I myself am cautious about bleeding-edge standards but C++14 seems a bit conservative in 2026. I tried both the GCC 13.3 and GCC 14.3 toolchains and C++14 was the default in both, while C++17 is the default of GCC since GCC 11 (C++ Standards Support in GCC).With another project and toolchain I once got nasty to track down bugs when bumping the C++ standard beyond the manufacturer's default so I'm wary to do this. What are the community's experiences using C++ standards beyond C++14?What is the general policy of ST regarding bumps of the default C++ standard version?Best,MarkusPS: I tried the CMake-based toolchain too, which in my case did not set a C++ standard explicitly, so going with my local compiler's (GCC15 C++17) default. As much as I prefer CMake - and appretiate the ongoing move to it - in general I would prefer to stay with the tried-and-tested STM32CubeIDE.

I recently upgraded my IDE to version 2.0.  I cannot start a project from the board view; where you select the board type and configure the settings.  It would then create the c++ project code for you.  The new version doesn't have anything to help you select the board and it cannot even open up the board configuration editor when you click on the .ioc file.  Is there. a way to revert back to the previous editor version - I think it was version 1.x.18?

I am unable to change the project name in STM32CubeIde, if i change it and try to open it i get error windows cannot find the file. They are all linked files, may be that is causing the issue, what changes i have to do avoid this error. The project is generated using MCSDK and after generation i am trying to change the project name in CubeIde. 

Hii Community member,I need technical help from someone who had faced this issue earlier described as below:I am currently working on STM32H723ZG mcu in which i had interfaced NAND flash of MX30LF4G28AC using FMC peripheral.As per our hardware test routine, I am checking flash test in which first a block gets erased and then each page is verify whether it is erased or not. Then a dummy buffer of 4096 get writes in a page and then read back into another buffer and comparing them. During comparison, my test passes for some pages and fails for some pages within block. When checked for failed pages, it is found that only last byte i.e. 4095th byte is differing. Although i had done configuration for 4Gbit model in cubeMx, my test routine is working for 2Gbit model.I would welcome any suggestion or some guidance point to resolve my issue.If any code snippet required, i will share on this chat.@TDK 

I updated CubeIDE to 2.0.0 (now CubeMX is separated) on MacOS. I started new project and want to set semihosting for debug. I did the configuration as I used to do in previous projects, but now when I try to run, I receive following error:Info : [STM32WB5MMGHx.cpu] Cortex-M4 r0p1 processor detectedInfo : [STM32WB5MMGHx.cpu] target has 6 breakpoints, 4 watchpointsInfo : [STM32WB5MMGHx.cpu] Examination succeedInfo : starting gdb server for STM32WB5MMGHx.cpu on 3333Info : Listening on port 3333 for gdb connectionssemihosting is enabledsemihosting fileio is enabledError: The 'gdb_report_data_abort' command must be used before 'init'.Below my configuration of OpenOCD: Where should I put the gdb_report_data_abort command?   

Hello,I am experiencing a flash upload issue with STM32CubeIDE(v1.19.0).The MCU I am using is STM32C091GCU6 with 256 KB of internal Flash.I am currently developing code to display image (IMG) data on an LCD.The image data is stored in Flash, copied to SRAM using memcpy(), and then transmitted to the LCD via SPI DMA.From the MAP file, I can confirm both the Flash addresses of the image data and the SRAM copy destination.The relevant MAP file entries are shown below: .rodata.IMG_HORIZONTAL0x08004840 0xfd20 ./Core/Src/font.o0x08004840 IMG_HORIZONTAL.rodata.IMG_VERTICAL0x08014560 0xfd20 ./Core/Src/font.o0x08014560 IMG_VERTICALAfter this configuration, when I build and debug using STM32CubeIDE, the reported uploaded memory size is only 128 KB.Because my code accesses image data located above the 128 KB Flash boundary, a HardFault occurs when running under CubeIDE debug.However, when I take the same build output file and program it using STM32CubeProgrammer(v2.19.0), the firmware is cor

Friends, I've encountered a bug while running CubeIDE 2.0 on my Ubuntu (KDE desktop). When I open my project, I notice the code editing area flickers. This often happens when the sidebar scrollbar is activated (forgive me, I'm not sure how to describe this element). Has anyone else experienced a similar issue? How should I resolve it? 

When I view the information panel after selecting the "X-CUBE-BLE2" -> "Device BLE2_Applications" -> "Application" -> "SensorDemoBLE..." and clicking on the "Documentation: STMicroelectronics X-CUBE-BLE2_GettingStarted..." link, the "Software Packs Component Selector" popup window hangs and cannot be closed.  The document is never displayed. From what I can tell, it is attempting to load "/home/me/STM32Cube/Repository/Packs/STMicroelectronics/X-CUBE-BLE2/3.3.0/Documentation/STMicroelectronics.X-CUBE-BLE2_GettingStarted.pdf". I ran the IDE software updates via the "Help" menu yesterday, so I assume it is the latest version.  The command line shows it is running "/opt/st/stm32cubeide_1.12.0//plugins/com.st.stm32cube.ide.jre.linux64_3.1.0.202310310920/jre/bin/java" with "-Dosgi.instance.area.default=@user.home/STM32CubeIDE/workspace_1.14.1 -Declipse.buildId=Version 1.14.1"The "Help" -> "About" shows:Version: 1.14.1Build: 20064_20240111_1413 (UTC)There were

Hi all, Is there any way to retrieve a list of all peripheral registers Address and Names for a specific MCU?I would like to have it as a json document,  My Approach right now would be to parse the MCU-Specific Header file in STM32 HAL. I would need to do it for many different MCUs, so I am looking for a possibility to have it done without huge manual effort.I am wondering if there is any easier way to do this, like extract from SMT32CubeIDE? Or maybe it is somewhere available already? Best Regards,Dietrich

I have// Prevent a compiler warning on fall-through from one 'case' to another in // a 'switch' statement // https://gcc.gnu.org/onlinedocs/gcc/Statement-Attributes.html #define INTENTIONAL_FALLTHROUGH __attribute__((fallthrough)) But the IDE flags it as a syntax error:and it's not just the macro: The usage is correct according to GCC documentation:https://gcc.gnu.org/onlinedocs/gcc-9.2.0/gcc/Statement-Attributes.html This is purely in the editor - the actual compiler gives 0 errors and 0 warnings.IDE v1.13.1 on Win 11. Seems to be a known Eclipse issue: https://bugs.eclipse.org/bugs/show_bug.cgi?id=567227

Hello everyone,I am facing an issue with the STM32CubeIDE V1.17.0 indexer, where it highlights a syntax error when using the C11 _Generic primitive. Due to company project policies, I cannot upgrade to a newer version of the IDE at this time, so I need to find a solution or workaround for V1.17.0.The indexer flags the code as a "Syntax error" as shown in the attached image:The PAR_SET macro is defined as follows: Key details:There are no missing includes or path issues.The code compiles successfully without any errors or warnings (GCC is happy).Runtime performance is intact, and the macro functions exactly as expected.The problem seems to be strictly with the indexer being unable to parse the C11 _Generic keyword correctly. Has anyone encountered this or found a way to "hint" the correct syntax to the indexer?Any suggestions are greatly appreciated!Best regards, Žiga

Hello. I am currently working on a NUCLEO-L152RE project in the latest version of the CubeIDE. I am running into an error where I can not install break points due to an "unmatched quote". I have tried the common fixes (New work space) for this that I could find online and it hasn't resolved it. I also ran fresh installs of the programs and encountered the same issue. Has anyone else encountered this problem? I have included a screenshot below for reference.   

I have a working project in STM32CubeIDE v1.19 for my STM32WB55RG board.  Pretty simple as it reads some sensor data, does an FFT and sends a couple results over Bluetooth.  It is working well and I'm happy with the performance.  I am on macos Tahoe and the highlighting of text in the editor is not working so I thought I'd upgrade to v2.0 to try to fix that problem.....what could possibly go wrong right?STM32CubeIDE v2.0 and standalone STM32CubeMX v6.16.1 install fine and I import the project into a new workspace and if I compile immediately after importing, it compiles fine....no errors.  I open the existing .ioc file in CubeMX and everything seems to load fine.  I make no changes and hit "Generate Code" just to make sure the new workflow is working properly.  No changes made but it apparently overwrites the existing app_ble.c file as a compile after refreshing the work done by CubeMX yields the following errors (snippets of output shown for brevity):&nbs

Is there an official docker image for stm32cubeide - we are building our firmware in an azure devops pipeline, and downloading the latest stm32cubeide deb package and installing it is time-consuming for the build. Looking on docker hub there are a number of stm32cubeide images, but none seem to be official from ST?(we have the headless build command working etc)

Hello, I am getting really frustrated with this issue for almost a week.I am trying to read PA1 and PA4 in DMA but I get only the reading of one channel and not the other one! I tried everything and I also looked at all the example online. Please help. 

Hi!Was hit by a non-obvious difference between the ARM and ST GCC toolchains.I installed the following toolchains (from the official ARM and ST websites) in two separate Docker containers.Their --version outputs are:ST toolchainarm-none-eabi-gcc (GNU Tools for STM32 13.3.rel1.20240926-1715) 13.3.1 20240614 ARM toolchainarm-none-eabi-gcc (Arm GNU Toolchain 13.3.Rel1 (Build arm-13.24)) 13.3.1 20240614 Then I compiled a simple main.c using the cyclomatic complexity option:arm-none-eabi-gcc -c main.c -fcyclomatic-complexity -o build/main.o Results:ARM GCC 13 reports:arm-none-eabi-gcc: error: unrecognized command-line option '-fcyclomatic-complexity' ST GCC 13 accepts the option without any error.So even though both toolchains report the same GCC version, the ST build includes this option while the ARM reference toolchain does not.This suggests that there may be additional differences between the two toolchains.When using both toolchains - or migrating from one to the other - be careful.Jus

Hello. My current set up is STM32Cubeide 1.19 which has an integrated version of the CubeMX (6.15)I'm currently working on some st git examples, that seem to have been created with CubeMX (6.16), thus i cannot open the .ioc file on cubeIDE. I installed cubeMX 6.16 in order to edit the .ioc file and hit generate. Once i tried to build the project on cubeIDE though i got various errorsmake: *** No rule to make target 'C:/Users/asantorinaios/STM32CubeIDE/workspace_1.19.0/BLE_Beacon/Drivers/STM32WBAxx_HAL_Driver/Src/stm32wbaxx_hal_gtzc.c', needed by 'Drivers/STM32WBAxx_HAL_Driver/stm32wbaxx_hal_gtzc.o'. Stop. "make -j12 all" terminated with exit code 2. Build might be incomplete.If i try to exclude said file from the build, i another similar error. Is the cubeMX 6.16 incompatible with the 1.19 cubeIDE. Do i need to download cubeide 2.0 or is there another solution ?

In STM32CubeIDE, it is possible to view two different source files side by side by dragging editor tabs with the mouse. However, there is no keyboard shortcut or command to move the active editor to the left/right split.This slows down workflow when frequently comparing files (e.g., main.c and app.c). A command such as “Move editor to right/left split” with assignable key binding would greatly improve productivity.Best regards.
