STM32CubeIDE (MCUs)

Hi ,I have IAR license and I want to build the code on CubeIDE but use the IAR compiler is there any simple method for eg IAR plugin or anything else

Hi,In STM32CubeIDE code editor when I go over a variable or function the tool tip window that opens and shows the declaration of variable or implementation of the function  - the window has a black (very dark background ) and text is also black and not visible.Can anyone tell me where can I change the background color or text color of this tool tip window?Regards,Cristian  

I have some problem, I Can't login STM32 IDE - 1.18.1 Version Manu : Help → STM32Cube updata → Connection to myST → Enter myST account information So, Open the Uset Authentication Dialog, but i can't see anything. i need help, please  

I recently bought an STM32H735G-DK and wished to start by blinking its LEDs. Unfortunately, I have been struggling to get to the coding menu, as an error attached below would show up every time I created a new project, saying that I would have to log in and download a software package. The problem is that I have logged in numerous times through the CUBE IDE as instructed, but no download option comes up (I log in successfully? and the popup window closes, and nothing changes). Other people seem to have had similar problems online; however, no one had a viable solution, and thus, I am still stuck trying to access the coding menu to get my device to blink its LEDs. I have tried deleting and reinstalling the CUBE IDE software, as well as manually putting files into the repository; however, nothing has worked thus far. Any help would be greatly appreciated. Thank you. 

I have a dubt:I'm using c++, touchgfx and FreeRTOS: new and delete operators are thread safe ?   What they mean "Be warned that (at the time of writing) the current newlib design implements a system-wide malloc() that must be provided with locks" ? They provided locks on malloc ?  

Hello team,For the development purpose, I want to update the stm32cube ide.I am updating ide from path "Help-> Check for updates"I am having following issue.An error occurred while collecting items to be installedsession context was:(profile=STM32CubeIDE, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).Problems downloading artifact: osgi.bundle,org.bouncycastle.bcprov,1.72.0.v20221013-1810.Error reading signed content:C:\Users\RDESHP~1\AppData\Local\Temp\signatureFile4487422626405765759.jarAn error occurred while processing the signatures for the file: C:\Users\RDESHP~1\AppData\Local\Temp\signatureFile4487422626405765759.jarCould you please help me to resolve this?We have Zulu java installed. Thanks,Rahul D

Hi I'm working on implementing a bootloader on a Nucleo H723ZG and attempted to relocate the application to a different flash address. During testing in the debugger, I found that the application only runs correctly when I explicitly specify the vector table address. Without this, the system ends up in a fault (trap) state. I have the linker file adjusted The defines ready:I have no idea what else could go wrong...Thank youBR

Split from STM32CubeIDE and STM32CubeProgrammer produce different results when flashing .elf files.Hello everyone, and sorry to dig up this thread (as it's been left open).We're also experiencing this issue, and it's impacting the CRC calculation due to a few 0x00 bytes that, for some unknown reason, are 0xff in Flash (first image below), thus preventing an update from being applied because they're incorrect.When programming directly with CubeProgrammer, everything goes well (second image below), and we do indeed find the 0x00s. But this means that debug tests will no longer be possible due to the erroneous data in Flash...I tested on CubeIDE v1.8.1, v1.8 and even the v1.17.0, but the same problem persists. A "monitor flash mass_erase" doesn't fix the problem. Everything seems fine when using CubeIDE v1.15.1 but the generated binary isn't the same.The incorrectly written data corresponds to the assignment of an ALIGN (third image below), which is enough to distort an entire verifi

Hi.    I cannot start a new project in the STM32 IDE. Tested in 2 diferent instalations (computers) and the same error ocurrs:    STM32CUBE_FW_H7_V1120 CANNOT UNZIPPED NO LOADED    STM32H743      

Hello!I am trying to configure the project to run X-Cube-AI. When opening the attached try_ai.ioc file in STM32CubeIDE 1.17.0 the window freezes. Also tried to open it in STM32 CubeMX 6.13.0, no success. The board is NUCLEO-N657X0-Q.Could you please help me to troubleshoot this issue?Regards, David Alami

Dear STMicroelectronics Support Team,   I am working on the STM32F407G-DISC1 (STM32F4 Discovery) board and I am unable to watch printf() statement in SWV ITM Console output in STM32CubeIDE.   To enable the SWO trace output, I referred to the user manual and identified that SB12 (SWO) was in OFF state by default. Following the recommendation, I removed the 0-ohm resistor between the SB12 pads on the backside of the board and directly shorted the pads using solder to connect the SWO signal to PB3. I also attached an image of the soldered SB12 pads for your reference.   Here are the board details:   - **MCU Model**: STM32F407VGT6   - **Board**: STM32F4 Discovery   Could you please advise if any additional configuration or hardware action is needed for the SWO functionality to work properly? Request you to send me a reference video link for any modifications mentioned by you.   Thank you for your support.   Best regards,   Vakati Heman

CubeIDE version 1.2.0 Cloning a git repo with a .ioc file in it, how to generate code?When right clicking the "Generate code" is grayed out. The only method that has worked seems to be opening the .ioc file, toggling a checkbox to generate a change and then saving to cause code generation. Is there a way to generate code when ever I want? or force the code generation even if there are no changes detected?

The Toolchain Manager takes 5–10 minutes to load the toolchain list, even with only a few installed.It happens every first time I open it after launching the IDE.If I close it and reopen it during the same session, it loads instantly.But if I restart the IDE, the delay returns.Is this normal behavior?If so, is there anything that can be done to speed it up?STM32CubeIDEVersion: 1.18.1Build: 24813_20250409_2138 (UTC)

Hello all,I have been hanging on to an anctient version of ubuntu for a LONG time because I need to use STM32CubeIDE,sadly, IT required me to update because you know..... security and stuff.I was resisting because I knew I would get this error:Could not determine GDB version using command: arm-none-eabi-gdb --version arm-none-eabi-gdb: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directoryAnd I had tried to install the required file before, even add a symlink to the so.6 version in the past with no luck. So today I made the update, and when I hit debug right after re-installing the Ide, i got the lovely message.So it this it for me? Do I need to bug IT to get me a new PC simply to run an old version of ubuntu or is there some way for me to actually run this?I am guessing no as it seems to be part of the ide...My current version is: base: Ubuntu 24.04 nobleAnyone else have any luck with this? I read some other posts about this

Hi I am new to STM32. I am porting a design from NXP's Crossover Processor RT to STM32H7xx. I have a Nucleo H743 eval board that i started using and testing.I have created a new project in Cube IDE V1.18.1, selected H743,  and selected various modules and configured IOs for those. I intend to use ethernet in RMII mode, QSPI Bank1, SDMMC1, 2xI2C, 4xSPI, 4xUART/USART, USB FS.I get conflicts other than the pinouts. I guess that it is because of Clock/DMA or some internal resource. I read the reference manual (RM033) and data sheet of H7, also pdfs of QSPI, SDMMC, I2C etc. But could not find out what to check and correct. In parallel I am doing the hardware schematics too. Need help/pointer so that I can address the limitations and create a correct hardware design.Thanks.

Hello,I am using an STM32F103VCT microcontroller and the EEPROM emulation library. I write data with the EE_WriteVariable() function and read it back with EE_ReadVariable(). However, whenever I download new firmware to the MCU via ST-Link V2 in STM32CubeIDE, the entire flash memory is erased—including the regions where I stored data using EE_WriteVariable().Is there any way to download or debug new firmware without erasing the flash pages used by the EEPROM emulation?For reference, I’m running STM32CubeIDE version 1.18.1. Any suggestions would be greatly appreciated.Thank you!

Hi, I am trying to interface on board microphone in STM32H757I-EVAL. I am trying to use PDM format data. In STM32 Cube IDE, I am trying to configure PE2 as PDM_CLK but it is not listed in the pin configuration. I have attached the image. 

Has anyone successfully used the BSD addon for netxduo inside CubeIDE?  I followed the instructions at the top of https://learn.microsoft.com/en-us/azure/rtos/netx/netx-bsd/chapter2 (the #define TX_THREAD_EXTENSION_3 int bsd_errno needed a trailing semi-colon) but the netx timeval and fd_set definitions conflict with the CubeIDE environment (/ST/STM32CubeIDE_1.10.1/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.11.3.rel1.win32_1.1.1.202309131626/tools/arm-none-eabi/include/select.h and /ST/STM32CubeIDE_1.10.1/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.11.3.rel1.win32_1.1.1.202309131626/tools/arm-none-eabi/include/sys/_timeval.h).My only reason for using BSD is to to implement ModbusTCP with libmodbus .  I would gladly opt for a native netx implementation of ModbusTCP if anyone knows of one.

 How to import assembly files and compile them in STM32CudeIDE ?When I create a .s source file in a project, I cannot even save the file, and STM32CudeIDE only reports an error:Save failedAST is empty

I am writing multiple libraries that use either I2C or SPI for communication.  I recently discovered that the STM32F4xx family had an interesting "feature" that will take the SPI NSS signal low and keep it low until the SPI module is disabled versus toggling the NSS line based on data transmission when hardware control is specified for the NSS signal.  I want the libraries I am writing to be "smarter than the average bear" so a user who has no knowledge of any particular MCU's quirks can easily use the library.Taking a generic SPI Flash memory module as an example and using the aforementioned STM32F4xx family MCU, is there a "define" specified within the IDE or the HAL's that will allow me to do something similar to the following code snippet?  I found something similar to what I am trying to achieve in the system_stm32f4xxx.c file that is auto generated by CubeMX/CubeIDE.  I am just looking for a way to cover an entire family of MCU's.#include "stm32f4xx_hal.h" #in

STM32CubeIDE and STM32CubeProgrammer exhibit different behavior when flashing an MCU. Specifically, "gaps" in memory sections described in the linker script are flashed to a device with 0xFFFF when using the IDE and 0x0000 when using the programmer. For example, this will be the case for the few addresses after ".isr_vector", but before ".text".I noticed this when programming an STM32G474RE to perform a CRC on its own flash on startup as part of data integrity check. I appeared to get different CRC results depending on whether I had programmed the unit through the IDE or the CubeProgrammer (despite using the same .elf file, ST link, and PCB). Ideally, I think STM32CubeIDE should probably be updated to match the behavior of STM32CubeProgrammer for consistency.This was done using STM32CubeIDE version 1.13.0, STM32CubeProgrammer version 2.14.0, and STLinkV2.

 This IDE has gone into some crazy mode where each window maximizes itself on the screen/. I've tried clicking every single maximize/minimize/restore button, closeing the app, restarting the computer.....This worked and suddenly broke.Is there some way to make this thing reset back to it's default state?   

I've been receiving this error for several times please help me trying on f446re
