STM32CubeIDE (MCUs)

Hello I have a question.The '0' s instead of 0xFFFFFFFF in the memory is something that really occurs on the flash memory or it is a value that appear because the stm32cubeide is not able to read all the position of the memory, or in other words, the IDE is unable to confirm that the memory is empty.  Thanks a lot.  

I have just updated the IDE from 1.12.1 and updated my project as requested but I have encountered an issue when compiling.I get 3 errors on previously compiling  source code. as followsCan you help with what might be the problem?PhilW

Hello,we're maintaining assembly projects to teach baremetal assembly programming on STM32H750 board.Project used to compile without and warnings, but lately we're getting new errors.Project is stripped down to bare assembly and probably something is missing... This is output : 19:36:14 **** Build of configuration Debug for project stm32h7-asm **** make -j16 all arm-none-eabi-gcc -mcpu=cortex-m7 -g3 -DDEBUG -c -list -x assembler-with-cpp -MMD -MP -MF"Core/Startup/startup_stm32h750xbhx.d" -MT"Core/Startup/startup_stm32h750xbhx.o" --specs=nano.specs -mfpu=fpv5-d16 -mfloat-abi=hard -mthumb -o "Core/Startup/startup_stm32h750xbhx.o" "../Core/Startup/startup_stm32h750xbhx.s" arm-none-eabi-gcc -mcpu=cortex-m7 -g3 -DDEBUG -c -list -x assembler-with-cpp -MMD -MP -MF"Core/Src/Main.d" -MT"Core/Src/Main.o" --specs=nano.specs -mfpu=fpv5-d16 -mfloat-abi=hard -mthumb -o "Core/Src/Main.o" "../Core/Src/Main.s" arm-none-eabi-gcc -o "stm32h7-asm.elf" @"objects.list" -mcpu=cortex-m7 -T"D:\D

I am attempting to debug code on a Necleo-U385RG-Q board using STM32CubeIDE V1.18.1 under Windows 11. I beleive that under \plugins\com.st.stm32cube.ide.mcu.externaltools.openocd.win32_2.4.100.202501161620\tools there should be a scripts directory that contains cfg files for ST-Link V3 and my board. However, there is no scripts directory anywhere in the installation. Nor is there for my STM32Cube Programmer installation. When setting up the debug configurations I am able to select ST-Link GDB Server as a debug probe. This does get the board's serial number. However, because of the missing files I expect to see in the scripts directory, I get nothing when selecting ST-Link OpenOCD. I believe I should put the path to the cfg files under OpenOCD options.

Hello,I haven't seen anyone else bring up this issue on here. I am trying to use the HAL ADC and USB at the same time but whenever i use HAL_ADC_Start_DMA() the USB becomes unrecognized by my computer. When I comment out the line that the HAL_ADC_Start_DMA() call is on the program works fine. Here is an example program I wrote to illustrate the issue. IDE Version: 1.18.1Part Number: stm32f072OS: Windows11/* USER CODE BEGIN Header */ /* USER CODE END Header */ /* Includes ------------------------------------------------------------------*/ #include "main.h" #include "usb_device.h" /* Private includes ----------------------------------------------------------*/ /* USER CODE BEGIN Includes */ #include "usbd_cdc_if.h" #include <stdbool.h> #include "usbd_def.h" #include "usbd_core.h" #include "stdio.h" extern USBD_HandleTypeDef hUsbDeviceFS; /* USER CODE END Includes */ /* Private typedef -----------------------------------------------------------*/ /* USER CODE BEGIN

 Hello,I’m working with the STM32F767ZI board and have configured Ethernet (ETH) peripheral with LwIP middleware using STM32CubeIDE. After generating the code and trying to compile the project, I encounter the following error: arduinoCopyEditld.exe: cannot find .: Permission deniedThis issue started occurring only after enabling the Ethernet peripheral and LwIP middleware. Prior to this configuration, the project was compiling successfully.Steps Taken:Enabled ETH in RMII modeEnabled LwIP with default settings (static IP)Generated code using STM32CubeMXTried cleaning and rebuilding the projectAdditional Info:STM32CubeIDE version: [your version, e.g. 1.13.0]Toolchain: ARM-GCC (default from CubeIDE) Request:Could someone please help me identify why this "Permission denied" error is happening and how to resolve it? Also if the configuration has some other possible issue for ethernet not to work. I am attaching some conf images from cubeMX below     &

When I write 1 at the position of EXTI0 (6) in the ISER of the NVIC, the value is written to both ISER0 and ICER0. What is the problem ? related to stm32f103c6t6.

Hi, I'im running X-CUBE-AI with STM32Cube IDE on a F407 Discovery. When I try to perform validatation on target, I get the following error during building stage :  Building project /opt/st/stm32cubeide_1.18.1/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.13.3.rel1.linux64_1.0.0.202410170706/tools/bin/arm-none-eabi-gcc -c -mcpu=cortex-m4 -mfpu=fpv4-sp-d16 -mfloat-abi=hard  -DDEBUG -DUSE_HAL_DRIVER -DSTM32F407xx -D  -IMiddlewares/ST/AI/Inc -IDrivers/STM32F4xx_HAL_Driver/Inc -IDrivers/STM32F4xx_HAL_Driver/Inc/Legacy -IDrivers/CMSIS/Device/ST/STM32F4xx/Include -IDrivers/CMSIS/Include -IInc -O3  -Wall -fdata-sections -ffunction-sections Src/system_stm32f4xx.c -o Debug/Src/system_stm32f4xx.o <command-line>: error: macro names must be identifiers make: *** [Makefile:72:&nbsp

Hi.I add the "x-cube-eeprom-v8-0-0" library to my project manually:I create folder Middlewares and copy sources the  folder as expected,I specify the paths in the project settings,I uncheck the "Delete previously generated files when not re-generated" on the Project Manager tab in Device Configuration Tool,but the folder is still deleted when regenerating after changing the any settings in ioc.What am I doing wrong?

Hi, I want to get data from an ADC connected externally through SPI DMA whenever data ready pin is set. I want to do it without any interrupt handler, since our firmware have already loaded with other stuffs. I have tried the synchronisation of SPI DMA with GPIO EXTI trigger. It works when I configure SPI DMA in circular mode only.Because synchronisation doesn't triggers the SPI DMA it just syncs the process. I can't find any options to trigger the SPI DMA with timer or any event.How to trigger SPI DMA through GPIO EXTI event? Is that possible in STM32G4 series?. Thank you!     

I just installed the latest STM32CubeIDE 1.18.1 on a mac Studio M2 running Sequoia 15.5.  The default GNU make on the machine is /usr/bin/make, version 3.81.  The IDE is clearly creating makefiles for a later version of make, because building applications in the IDE errors out with "**** multiple target patterns" on a make rule that lists the elf and map files as targets.  I have make 4.4.1 installed via brew, but how to tell STM32CubeIDE where to pick it up is buried somewhere and I'm not seeing anything in any documentation.  Does anyone know how to fix this? 

Hello, I am new on the embedded subject, and I need some help.I want to practice I2C communication, so I connected Nucleo-L4P5ZG (master), and MAX6604EVKIT (slave), the general goal is to read registers and send the result via UART.I used the STM32cubeMX to generate the initial code.I used the HAL function " HAL_I2C_Mem_Read"  to read register in address 0x6.Build process went without errors.During debug, when looking at the scope, it seems that the MCU don't change the register address to 0x6, and it is stuck on 0x0.The slave address is correct, and I receive ACK (0 logic).I am attaching the main.c.Do you know what seems to be the problem?ThanksShay 

Hello,I am working on USB Device VCP project but I have problem about defines,index,etc. As you can see below that I have definition of "STM32N655xx" but I can not include "stm32n655xx.h".I tried Index, Rebuild step but it did not fix. On the other hand, I am also getting this problem for other files. My code is giving hardfault because it can not acces to "HAL_PCD_MspInit" while initializing "HAL_PCD_Init".I started getting code generate problems from .ioc file for N6 series but i will start new thread for this problem.Edit:I also forget to mention that CMSIS drivers outside of project folder as you can see below.I have "STM32N655xx" define inside of this projects but this folder can not acces to this symbol. If I can fix this, problem will be solved but I do not think that I have to do anything for this problem. Is this a bug? Thanks for help,Best Regards.

Hi guys,I m currently trying to debug my custom prototype stm32G474CEUx based project using stm32cubeide 1.18.1 version. But Once I set the breakpoint at particular line and then I try to step into it in debug mode,  then It would not go to that function inside, instead it goes somewehere. It seems bit strange. Previously it dd not happen. Actually i restarted the cubeIDE  but it did not work out.In fact previously my project was giving the correct result but after this issue, i am not getting the correct result on serial terminal.Can anyone please guide or help me for this.?  Many thanks in advance.!

I would like to use SWV for debugging on the Nucleo-N657X0-Q board.I first enabled SWV debugging and also change the CPU clock to 400 MHz.   Then, I added some code to main.c (as reference here ).At the same time, I also set the core clock to 50 MHz in the TRACE configuration of Keil.But i can't see any string in Debug Viewer.Does anyone know what else I should check? Thank's 

Using cube IDE to debug my application i've witnessed breakpoints behaving unpredictably: sometimes they appear on their own in breakpoint list view while not present in the file editing view; other times the breakpoints i've just placed and just used dissapear.What can be a cause of such behaviour and how can i prevent it from happening?

I have imported several example projects into CubeIDE which don't show the header files. The header files do actually exist in the windows file explorer, and the project does properly build and run. So why don't these show up on the CubeIDE (Eclipse) project view? Is there some Eclipse setting that I am missing?

Hello,I'm new to STM32Cube-IDE (and Eclipse). Normally I use the ARM-gcc toolchain and do assembly coding.I managed to create a New STM Project by using the Example Selector tab in the Target Selection window.In this case it was the BSP Example for the B-U585I-IOT02A Discovery Kit (with the STM32U585 chip). After modifying the code in accordance with how-to-use-semihosting-with-stm32cubeide  the code runs OK. Now I would like to COPY the Project and edit that. From the multiple "how to clone a project" threads it appears that this is not trivial. (?) One of the threads I read was from 2022 and IDE version 1.8. It seemed that multiple otherwise experienced developers found it odd that this wasn't a straightforward task. Manually copying and search/replace seems very odd and error-prone.Has there been any progress on automating this?  In my case there aren't even any .ioc or .project files. As expected, the following don't work:Simply copying the P

... ideally automatically as part of a normal Debug or Release build.

I am using CubeIDE version 1.11.0 for a STM32F411RC project. After i've changed boards (between two equal custom boards), my live expressions started showing wrong values. The values are only wrong in the live expression, because if I halt the program and read them, they are correct. I've tried removing the variables from the live expression and inserting them back again, but it didn't work. I also tried turning my variables volatile. I also removed all optimizations, but to no avail. I erased and remade my debug configurations from scratch, but it didn't change anything. The only thing that worked was turning on the Serial Wire Viewer (SWV) in the debug configurations. It worked once, but when I stopped the debugger, did some changes, and started it again, it was all wrong all over again. It never got right again after that. Is there some kind of configuration I am missing? The only thing I didn't try yet was reinstalling the CubeIDE.

I bought an analysis program from a company and they gave me a plugin .jar file to install the analysis program in IDEs. When I put this plugin .jar file in a folder called dropins in the Code Composer Studio IDE folder, it works directly. But in STM32CubeIDE version 1.16 there is no dropins folder, even if I create it myself it doesn't work. When I tried to install the plugin as jar with the “local” option from the “install new software” screen, it didn't work. I don't have the Update site folder, only the .jar file. How can I install it in STM IDE as it is installed in CCS IDE?

Hello all, i have reported it several times but ST has successfully ignored it. So i am posting it here. In CubeIDE is folding not working if file is long (around 3k lines). This is a major problem because a lot of LL "drivers" (BTW, it is RAL-Register Abstraction Layer) are quite long. Most of the lines are comments, and if you are unable to fold them, the files are hard to use, harder to read and it makes confusion and anger. If you are writing some module, which has to be longer, it will be also hard to use and read, and user could insert a duplicity which lead to bugs.  Please fix it finally.

I am using STM32CubeIDE version 1.18.1, and when using float formatting, STM32CubeIDE shows me an error with red squiggles about float formatting not being enabled in my toolchain.When I go to Project Properties > C/C++ Build > Settings , I see no 'Tool settings' menu, and no linker option to specify. I am using CMake, so I believe this is normal since STM32CubeIDE does not know about my build configuration. How can I make this error disappear while using cmake ?
