STM32CubeIDE (MCUs)

I am developing a program to enable the USART3 (initially as a UART) of the STM32H755 (NUCLEO-H755ZI-Q) and use it to transmit information through the functions "__io_putchar" and "printf" but it does not work. At first I thought it was an error in the baud rate calculation, I searched the reference manual and understood that the default clock after the reset is 64Mhz, through the HSI, I made the change, but it still does not work. Here is the file with the settings and functions:#include <stdint.h> #include "stm32h755xx.h" #define SYS_FREQ_64M 64000000 // sys_ck -> 64MHz #define APB1L_CK SYS_FREQ_64M #define UART_BAUDRATE 115200 void UART3_tx_Init(void) { RCC->AHB4ENR |= RCC_AHB4ENR_GPIODEN; // habilita o clock no GPIOD (PD9 - RX) GPIOD->MODER &= ~(0b11 << 18); // limpa os campos do PD9 GPIOD->MODER |= (0b10 << 18); // seta o PD9 no modo alternativo GPIOD->AFR[1] &= ~(0xF << 4); // limpa os campos do PD9 GPIOD->AFR[1] |= (0b011

Hi all!,I notice a different behavior from CubeMX, when starts alone or is called from CubeIDE.When I open CubeMX without CubeIDE, it works as espected. But when CubeMX is open from CubeIDE, it works in a strange way. Per exemple, when I try to put a MCU reference, with every key I stroke it tabs to "search" entry.Anyone with the same problem?Aftermore, this strange behavior happens sometimes, and sometimes dont...Here, CubeMX opened directly:and here opened from CubeIDE:My CubeIDE version: 

Hello everyone,I have been having an issue with breakpoints in STM32CubeIDE. Each time I try to set a breakpoint, IDE tells me that the breakpoint installation failed because of an "unmatched quote", like in the screenshot below: And when I run the program the IDE simply ignores all breakpoints that I set, because all of them, no matter where I try to install them, have that error.This is an annoying issue because sometimes debugging the embedded applications without using breakpoints is quite difficult.I have already tried to resolve the issue by creating a new workplace but to no avail.Can anyone please help me resolve it? Thank you in advance for your time.

Hi. I'm aware that there's a cli tool called  STM32CubeCLT which is used for building programs for stm32 MCUs. But, is there any way that we can ask stm32cubeIDE to perform the following steps?install/remove a certain cmsis-packconfigure a certain project to use certain components from installed packsgenerate code( The rest of the steps including building can be done through STM32CubeCLT)To give a bit of context:We're making cmsis pack to deliver software components to stm32cubeIDE and we'd like to automate the process of testing each pack in our CI/CD.  

Hi, I need help generating an .IOC file through the cube generator. What I need is USB Host FS. I'm having trouble getting it to work, specifically, there's no voltage on the VBUS output.I want to mention that I was able to create a USB Host HS that works and outputs voltage.Thank you!Itzik

I was performing simple arithmetic calculation, and wanted to check the data gets stored in Flash and SRAM memory.While checking the memory browser all I see is ?????. Could anyone guide me, what's the issue here?

Any idea how to solve this? My board is: stm32h753ZI, I think it has plenty of memory, but I don't know where or how to modify it, or which bank to choose. Where could I find info to configure it and also learn more about the subject? Thanks

Updating the cubeide generates this error:An error occurred while collecting items to be installedsession context was:(profile=STM32CubeIDE, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).Result of processing steps.OKOKOKPublic key not found for 70b824d9a6b4ae29.OKI could just intall the latest version, but I assume there is a way to fix this.  Thanks,Jamie

Hi, I wanna use TDD on my projects. So; I try implement CppUTest or Unity Test Frameworks but i couldn't do it. Is there anyone use this test framework on STM32CUBEIDE? What could be wrong? When i try build project , i get so many errors. (like : no such file or directory...)if there is a tutorial for beginning TDD for STM32CubeIde , it would be so helpful.Best Regards..

Hello. I have a project which was worked fine about 3 years. But after update to 1.13.0 I am catching a hard faults at start. I am discover that hard fault happens inside MPU_Config(); function. Also I found that new version has change init order:And here is my  MPU_Config:  void MPU_Config(void) { MPU_Region_InitTypeDef MPU_InitStruct = {0}; /* Disables the MPU */ HAL_MPU_Disable(); /** Initializes and configures the Region and the memory to be protected */ MPU_InitStruct.Enable = MPU_REGION_ENABLE; MPU_InitStruct.Number = MPU_REGION_NUMBER0; MPU_InitStruct.BaseAddress = 0x30040000; MPU_InitStruct.Size = MPU_REGION_SIZE_256B; MPU_InitStruct.SubRegionDisable = 0x0; MPU_InitStruct.TypeExtField = MPU_TEX_LEVEL0; MPU_InitStruct.AccessPermission = MPU_REGION_FULL_ACCESS; MPU_InitStruct.DisableExec = MPU_INSTRUCTION_ACCESS_ENABLE; MPU_InitStruct.IsShareable = MPU_ACCESS_NOT_SHAREABLE; MPU_InitStruct.IsCacheable = MPU_ACCESS_NOT_CACHEABLE; MPU_InitS

Posted on January 19, 2012 at 20:58We have a problem with the nRST pin of a STM32F100CBT6 microcontroller. We have been working on the problem for several days and we don�t find out what is exactly the cause of this problem. The problem lies in the nRST pin. There is nothing but a pull-up 10KOhms and a 100nF capacitor connected on this pin, but the pin does't go high. For an unknown reason we see an unstable signal on this pin during some seconds, that fluctuates around 2.5 Volts to 2.7 Volts. After a period of 1-10 seconds the reset signal goes to low and remains there forever. The only way to take the microcontroller out of the reset is to force a 3.3V level onto this pin. When the pin is again released, it behaves well during some seconds (3 to 20 seconds), then it starts the fluctuations during some seconds (20 seconds or more) and finally falls again to reset. Power supply is applied through a linear regulator (LM1117-3.3) to all the VDD and VDDA pins. We have checked pin by pin

Hello,After updating STM32CubeIDE to version 1.16, starting a debugging session doesn't load program into the STM32L5 target and jumps directly to the reset Handler.I tried programming the bin file using STM32CubeProgrammer and it works well.However, erasing the FLASH using STM32CubeProgrammer and launching a debug session then reading back the FLASH using STM32CubeProgrammer shows that it's empty.Im trying to load the program to the address 0x08020000, here is the memories definition. /* Memories definition */MEMORY{RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 192KSRAM2 (xrw) : ORIGIN = 0x20030000, LENGTH = 64KBOOTLOADER (rx) : ORIGIN = 0x08000000, LENGTH = 128KFLASH (rx) : ORIGIN = 0x08020000, LENGTH = 352K}

Hi,I just tried selecting the STM32U5G9VJT6Q in CubeIDE and the "Next" button to start a project based on it is not enabled and there is a note at the top of the window saying it is not supported (see attached screenshot)?I assume that is incorrect and I perhaps need to download some additional data somehow (I didn't for other micros though)?Thank you 

Hello All,     I am using Ubuntu 24.04 and STM32 Cube IDE 1.16 version. When I try to  burn code to a STM32F401RE Nucleo board. I am getting below error. Could not determine GDB version using command: arm-none-eabi-gdb --version arm-none-eabi-gdb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory and yes I have tried sudo get-install.Does STM team has any suggestion ?Thank you

Hello, myself and a coworker both have tried 1.16.1.  We have a cmake based project, when we open, and try to run the CMake configure step, the IDE tries to do something and is then silent.  It looks like there's some permissions issue.  I looked at the error log.  Both of us go back to 1.14, and its fine!  So, this is discouraging.    

I'm trying to debug a STM32 project on an STM32 IoT Discovery Node Board (B-L475E-IOT01A1) from my MacBook Pro (M1 Max running Sonoma 14.5). Every time I build and start a debug session, the process gets stuck on "Launching : Performing pre-launch check..." as shown in the figure below.When it get's stuck like this, it can't be canceled and the only way to clear the process is to restart the IDE. I am new to this kind of debugging, but I have a feeling this is a problem with the USB connection and drivers because when I restart my computer, it usually works (without changing any of the project settings or configurations).ST-link server is running on my machine, and seems to have connected properly as shown in the output for the following commands.Is there any known way to resolve this error? Restart the drivers or reconnect ST-link? Restarting my computer every time is not really a long-term solution. I'm sorry if this is a dumb question, I am new to CubeIDE.  edit:

I'm using TrueStudio for my previous product coding/debugging.  I downloaded some example projects from ST website,  there are options for IAR/Keil/STM32CubeIDE, is TrueStudio fully replaced by STM32CubeIDE?I'm get used to TrueStudio, is STM32CubeIDE much better than TrueStudio?  

Hello,This is now the third Nucleo board that has been "bricked" by a forced ST-Link V2-1 update. I can no longer program the board. Windows 10/11 sees the board as a USB thumb drive (this has always worked) but from within the STM32CubeIDE it will not program the board. It says "waiting on debugger connection" but hits a time out. So then using the STM32CubeProgrammer I get the error message "Error: No STM32 target found"Like I have said this has happened to 3 other Nucleo boards I have and I cannot program them anymore. I am tired of the IDE forcing an update to ST-Link and the update bricks my board making it useless. I tried saying "No" when the IDE asks me to upgrade the ST-Link firmware. But then it says it cannot program the board with out first upgrading the ST-Link firmware. So then I update the firmware and cannot program the boards anymore. How can ST release such buggy firmware for the ST-Link programmer on their OWN Nucleo boards. I have real production issues to

Hello Community!In my current project with the NUCLEO-H7S3L8, I am encountering some problems that seem a bit confusing and strange. As a starting point i used this Template from Github, which was the only way i didn't receive an error during programming (some Trouble with a MI command ... another open point).Everything works fine with the base template, but when i'm adding additional peripherie like usart3 and adc1, there seems some trouble with the project configuration. During comparing the drivers-folder of the top-project and the sub-project, i recognized that they are different. I though the driver-folder in every sub-project is a link to the folder above, but i thing something is messed up at this point.This is the project explorer view of the unchanged template. Both driver folders were identical.and here we can see that those files didn't exists in the driver-folder of the sub-projects when re-generating the project with the .ioc-file after adding the uart3 and adc1.Shouldn't

Hello community, Few days ago, some post linked to performance issue with STM32CubeIDE on Ubunto 24.04 and Debian testing [trixie] machines. This is a known issue in ECLIPSE and was not causing issues for STM32CubeIDE, however with the new Linux distributions the problem occurs. Temporary solution: As a temporary solution there are two propositions: Make temporary changes for each STM32CubeIDE start.set the hard limit in current terminal : ulimit -n -H 4096 Make change for the entire system: edit /etc/security/limits.conf and add the line “username hard nofile 4096” Long term solution: The long-term solution will be the integration of the newest Eclipse version in STM32CubeIDE

Hi,Trying to use I2C1 with REMAP=0 and as long as understand the SCL and SDA pins are PB6 and PB6. Along with I2C I am using some other peripherals as well. I am unable to select PB6 for I2C SCL PIN. Please see attached screenshot. Not sure why it wont let me select that default PIN. I am quite sure I am not using any other MASKED function for this PIN. 

Rather than resurrecting this thread, that never got a decent reply anyway, I will start a new one. I'm working on a design with an STM32L072, where I use the internal EEPROM to store about two dozen parameters. These parameters are all initialised in my code, but when I load the debugger, their values are not loaded and remain all 0's.As these parameters control the functionality of the device, this is extremely annoying. Doubly so because it is also not possible to edit these values in the debugger (contrary to f.e. STM8L151 / Visual Develop). STM32CubeIDEVersion: 1.16.1Build: 22882_20240916_0822 (UTC)OS: Windows 11, v.10.0, x86_64 / win32Java vendor: Eclipse AdoptiumJava runtime version: 17.0.11+9Java version: 17.0.11

Hello Community,A beginner here, apologies for the ignorance.A project was attempted to be made with a STM32WB55RG Nucleo board. Initially I wanted to hook up a peripheral pixycam to process the generated analog signal with the nucleo board to drive in turn other peripherals.The fear is that the nucleo board has been damaged by it, and I was wondering why that may have occurred. The problem being experienced now is that when trying to program the board, it gives an error saying the target device can not be found.The board is hooked up via the ST Link usb connector and J1 is set for powering via STLI. In ST32CubeProgrammer it gives the error:"Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication."When trying DA, it gives the error: "Failed to communicate with the target!" and "open_comms : 485 : open : Unable to detect DBGMCU Mailbox"Any connection configuration mode returns negatively.When connecting 3
