STM32CubeIDE (MCUs)

When I go to Debug => Open Console => Command Shell Console => Select Remote Connection, I have accumulated too many old connections. Any idea how to remove them? I am sure there must be a very simple method but it seems to have defeated me.

I am using STM32CubeIDE to program my board i.e. STM32H7S78-DK. My file size is in large due to which it is flashing in external flash at address 0x70000000. In case of smaller file size i.e. less than 64 KB, it flashes in internal flash at address 0x08000000. The flashing was working fine in internal as well as external flash. But, all of a sudden, I am getting below error log.-------------------------------------------------STMicroelectronics ST-LINK GDB server. Version 7.10.0Copyright (c) 2025, STMicroelectronics.

Hi,so i have a strange problem with SDMMC and USB msc :- custom board with H743ZI , 2x sd-card , 1x USB msc , for USB stick data;- software using HAL, FatFS etc; made on IDE 1.10 , migrate ...13, 15, 17, 18, now 1.18.1 (actual)- program working fine since > 1 year , but without DMA on sdmmc and usb/host ;- for debug/messages with SWO, SWV working , as it should;Now i tried using the DMA setting for sd and usb - no, nothing working.SD stays on waiting for first data transfer, USB hangs in a loop: connecting-disconnected-connecting....So i made a dummy test project, just debug + SDMMC1 + USB host, msc :surprisingly works "out of the box", can mount sd and usb and read, ok; but no SWV at all - nothing!Then i checked with CubeProgrammer (has SWV also) and it shows : something is sent, but hangs him up,last thing CubeProg showing is this : <unknown packet>  (then need to kill the prog, not any reaction)And now the really strange thing: on same hardware, same 200M core clo

Dear community members,I am using STM32CubeIDE to develop and debug the STM32H7 series dual-core microcontrollers, but I have encountered a stubborn problem and hope to get help and suggestions from the community.### Problem descriptionI used the built-in example project GPIO for testing according to the application note AN5361（You can refer to the attached content）.I was able to successfully compile, burn and debug the program for the Cortex-M7 core, but when trying to debug the Cortex-M4 core, I always received the following error message:```Error in final launch sequence:Failed to start GDB serverFailed to start GDB serverAn error occurred while initializing the ST-Link device.Reason: (255) Unknown reason. Please check the power supply and cable connected to the target machine.```More specifically, the debug console shows:```Failed to read ROM table via AP 3Error in initializing ST-LINK device.Reason: Unknown. Please check power and cabling to target.```### Solutions I have tried1.

The is voltage sensing in live expression I'm using STM32F103C8T6 board popularly known as blue pill im using a voltage divider the supply is given from the power supply and the ADC pin i use is B1 from the power supply when i give less than 2V the output in the live expression is accurate but when i give more than 2V and less than 3.3V it is not correct and for example if i give 3.3V in the live expression the output shows is 5.1345V how to resolve this problem any ideas gentlemen's 

I am using CubeIDE to code on my STM32 Blue Pill to display a string on my serial monitor but it is only available on loop. Is there any way to print it on serial monitor once ??And how can I read values from the serial monitor and use as an input value ??

Hi all,This is my first embedded programming project and Blue Pill is my first board to work on. Since I've got some experience in C++, I wish to use that language to make a project for blinking the Blue Pill's LED. Amongst various IDEs out there I picked up STM32CubeIDE because I suppose they both are from a family and they're better to be used together.There are very many tutorials regarding Blinking Blue Pill's LED on the Web, but the problem with all I came across were two things: they all use the C language to program and also a pre-made code for the project. I want to use C++ and write the code myself.After installing the IDE, I created a new STM32 Project called "Blinking LED" and then selected C++ as the target language and I'm stopped there. What I need now is a guidance to conduct me from that point up to the IDE's code editor where I can put my own C++ code for the project to be run on the board.

Hi AllToday I wanted to start working with Bluepill DAC that turn out in STM32CubeIDE there is no DAC peripheral and I was shocked. Does anyone know what the h... is that issue? and how to solve it? I don't like to configure it by myself.

Hi everyone,beginning the embedded systems journey has been fun, thanks to starting out with Nucleo board STM32L412RB-P. It's got an on board debugger (like any other nucleo board) which certainly abstracts the hardware nitty gritties required to setting up. Again, thanks to the rich ST community, one could find tonnes of resources and help readily available when stuck. I decided to take a little step further by purchasing a bluepill (original) and an STLink V3 SET (original). To my surprise, there hasn't been useful resources (in my opinion) on how to set these two up. Wherever the bluepill is mentioned, some stlink V2 (original or clone) follows. So I'm turning to this rich ST community, as trivial as this may seem, help me out of this quagmire. How do I do a simple debug, flash etc on my bluepill using STLink V3 SET using SWD. Thanks

Hello,I'm developing a USB bootloader for the STM32F103C8T6 Blue Pill (64KB / 128KB). I've seen many protocols and methods for doing this. Can you suggest the best method? I want to program the STM32F103C8T6 Blue Pill with STM Cube IDE software via USB.

I have recently bought 3 BluePills (STM32F103C8T6) and 1 ST-LINK V2 from ebay. I have been succesfully testing some old codes with Coocox Studio, but I decided to try out STM32CUBEIDE. Once I set up STM32CUBEIDE and built the program, I noticed that there's debugging option so I went with it. Unfortunately I wasn't able to debug the program - the chip would not be flashed successfully because the device would not be found or disconnected. I was/am receiving these messagesError in final launch sequence:Failed to execute MI command:-exec-runError message from debugger back end:Error creating process C:/Users/zdrav/Google Drive/STM32CUBEIDE/PWM/Debug/PWM.elf, (error 193).Failed to execute MI command:-exec-runError message from debugger back end:Error creating process C:/Users/zdrav/Google Drive/STM32CUBEIDE/PWM/Debug/PWM.elf, (error 193).Error creating process C:/Users/zdrav/Google Drive/STM32CUBEIDE/PWM/Debug/PWM.elf, (error 193).I also can't run the programError starting process.Cannot

hi. i want to write a variable into stm32h7b0vbt6 flash memory and all of the hal source and header files are added to project. so i have used FLASH_EraseInitTypeDef to erase flash first.but when i call that, the program not build and shows this error and warning:error: FLASH_VOLTAGE_RANGE_3' undeclaredwarning: variable 'EraseInitStruct' set but not usedhow to fix it?

您好，我遇到了一个非常棘手的问题。（STM32cubeIDE）当我打开朋友给的项目时，我在点击打开项目时遇到了以下问题。你能帮我解决吗？ Translation: "Hello, I have encountered a very tricky problem. (STM32cubeIDE) When I opened the project given by my friend, I encountered the following problem when I clicked to open the project. Can you help me solve it?"  

Edit by ST Moderator: This post has been translated from Chinese to comply with the ST Community Terms and Conditions (§10.2). Why is it that after turning off the computer after downloading and using it, and turning it on again, the cube won't open again? 为什么每一次下载使用完毕关闭电脑后，再次开启电脑，cube就没法再次打开了？

Just a question: I'm using the following code snippet: void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) { if (htim == mod_timer){ pwm_timer->Instance->CCR4 = sinetab[loop_cnt++]*global_adc1/4096.; //setzt neuen PWM-Wert aus Tabelle if(loop_cnt == MAX_SAMPLES){ loop_cnt=0; HAL_ADC_Start_IT(&hadc1); HAL_GPIO_WritePin(LED_GPIO_Port,LED_Pin, SET); } } } void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef *hadc) { global_adc1= HAL_ADC_GetValue(hadc); HAL_GPIO_WritePin(LED_GPIO_Port,LED_Pin,RESET); }  Do I have to care about  HAL_ADCEx_Calibration_Start(&hadc1 );If yes, I assume I would do that once in program start in main()? And how do I wait for calibration completion?

Hi,I try to debug a very simple program on a nucleo H563-ZI dev board.When i try to run the debugger, the program is well loaded into the flash.The debug session window displays the code below: Reset_Handler:ldr r0, =_estackmov sp, r0 /* set stack pointer *//* Call the clock system initialization function.*/bl SystemInit When i try to start the debug (step by step, or by clicking to the "play" button), it loops on Reset_Handler. If i press the stop button, the program starts and the led blinks. I was wondering if someone had already seen such a behaviour.Is the ST-LINK GDB server is well supported ?Thanks in advance   

hi,stm32h723zgt6 + W125Q128 + v2 stlink was working fine with  V.1.17.0. i had external loader issue with  V.1.18.0 version update and i was reported as well as in the past month .I knew downgrading ide version to  V.1.17.0 is the solution but my PC not supporting V.1.17.0 now .https://community.st.com/t5/stm32cubeide-mcus/nucleo-onboard-v2-st-link-with-cube-ide-version-1-18-0-stopped/td-p/778111  I thought recent release V.1.18.1 will be solution but  it's not erasing the external flash .Erasing memory corresponding to sector 0: Erasing external memory sector 0 Error: failed to erase memory

hello, I ask for the following clarification: I am using a two-channel encoder, A and B, and I want to estimate the rotation speed of the encoder shaft as precisely as possible. I started setting the TIM2 in encoder mode.My encoder generates 1200 pulses per revolution.I called the function: HAL_TIM_Encoder_Start_IT(&htim2, TIM_CHANNEL_ALL); and : void HAL_TIM_IC_CaptureCallback(TIM_HandleTypeDef *htim) { counter = __HAL_TIM_GET_COUNTER(htim); }which increases the counter variable every time a channel A (and B) get a variation (rising/falling edge settable from CUBE IDE).At one full revolution of the encoder, with my settings of frequency = 160 MHz, Ps =0 and ARR = 4800, the counter variable starts at zero and goes to the value 4800 at each full revolution, then goes back to zero, and so on (all visible via serial on my laptop by using Putty software). My question is: how can I estimate the rotation speed? I have read a lot of information about this but I am still confused. An

Hello, I am using the NUCLEO-h745ziq board. I am using two board for SPI loopbacking.One board as master and one board as SLAVE. Can we use the two debug window at time. Because I launch the one stmcubeIDE window 1.5.1 and another from stmcubeide 1.6.1 because i have only one drive C. When i debugging the two board, one board debugging ic completed when i try to debug second borad i get the error of GDB server failed. I am unable to undestand why it is shown .Becuase my two board independantly working when i debug it one by one.Can someone please helpme?

Hello,I've discovered the following anomalous behavior when attempting to use the STM32F103 Nucleo board:Pushbutton interrupt code will not execute if the RTC is active with NVIC EXTI13.  I've noticed that the RTC tamper PIN is also assigned to PC13 but I've made sure that the output selection is disabled and RTC tamper is deselected inside CudeIDE/CubeMX window.  If the RTC is activated with NVIC EXTI13, I measure zero volts across the appropriate pushbutton (pushbutton not depressed) pins (without the RTC activated the voltage across the same pins is 3.3V). My initial GUESS is PC13 is being reconfigured as an open drain output and being pulled low when the MX_RTC_Init is executed? I've tried to use the debugger to read the appropriate register and bit but I keep receiving a read error.  If I comment out the MX_RTC_Init function and download the program I receive correct functionality from the pushbutton but only after a computer reboot.I've also tried to execute the MX

How to change this theme, i couldn't find any settings related to this, i have tried all the colors and font settings, it comes default after installing STM cube IDE as fresh start. Somebody please help with this ?i have tried with ecllipse marketplace "Darkest theme" which i have installed, but it didn't apply , checked with settings under version control
