STM32CubeIDE (MCUs)

HiWe re trying to compile LoRaWAN_END_Node project from STM32WL Cube library. CubeIDE generate 402 MB  bin File. Can someone from STteam  look into this.MCU STM32WLE5CCMac Verion 1.0.3WL 1.3.1        ld file /* ****************************************************************************** ** ** File : LinkerScript.ld ** ** Author : STM32CubeIDE ** ** Abstract : Linker script for STM32WL55xC Device ** 256Kbytes FLASH ** 64Kbytes RAM ** ** Set heap size, stack size and stack location according ** to application requirements. ** ** Set memory bank area and size if external memory is used. ** ** Target : STMicroelectronics STM32 ** ** Distribution: The file is distributed as is without any warranty ** of any kind. ** ** Note : For specific memory allocation, linker and startup files must be customized. ** Refer to STM32CubeIDE user guide (UM2609), chapter "Modify the linker script". ** ***********************************

STM32CubeIDE 1.17.0, Win 11 x64I have a number of related projects in the space workspace (WS). I can copy & paste them into the same WS with no problem within CubeIDE. New project folders are created within the WS directory & show up in the Project Manager list. All these project folders exist within the WS directory.When I import a project from outside the WS using Open Projects from File System... they import fine & show up in the Project Manager list. BUT when I try to cut & paste a project folder from outside of the WS directory into the WS directory via Windows Explorer & then try an add it to the Project Manager list in CubeIDE via Open Projects from File System... I get nothing, no import error messages, nothing. The project file doesn't appear in the Project Manager list, nothing!Anyone know why this is?

Hello,We had installed STM32CubeIDE 1.13.0 on a network drive (V: drive is the mapping), and it worked nicely to build a project cloned from git repo on the local drive (C:). With STM32CubeIDE 1.17.0 and 1.18.0, the IDE fails to build.  Even cleaning and re-building dos not make the build succeed.  If however the STM32CubeIDE is launched from C: drive, it is able to build the project. The CDT make lists the arm-none-eabi-gcc command line with all the right arguments, and there is no attempt to even run the executable.  The very next line has make reporting failure in the very first build in a subdir.mk file, and make terminates with exit code 2.This does not happen if using STM32CubeIDE 1.13.0 from the same network drive.

Hi,I'm running a fresh board on an STM32L431RCT6. I'm able to successfully run and debug a simple application that I created with STM Cube, but, when flashing our ported application (we have moved from Kinetis, due to the chip shortage), the stack frame looks like it jumped from 0xFFFF FFFE to 0x800 0008 to 0xFFFF FFF9 and then to 0x1FFF 3EEC. I've shorted PH3/BOOT0 pin to ground and checked the 0x800 0000 memory to make sure the first 8 bytes contain the top of the RAM and the address of the main function. They do. As you can probably tell, I'm not very familiar with the STM32 architecture, coming from Kinetis.Thank you!

Hello,Hard Fault Handler Code:To capture the details of the Hard Fault, I’m using the following handler:void HardFault_Handler(void) { __asm volatile ( "TST lr, #4 \n" "ITE EQ \n" "MRSEQ r0, MSP \n" "MRSNE r0, PSP \n" "B hard_fault_handler_c \n" ); } void hard_fault_handler_c(unsigned int *hardfault_args) { unsigned int stacked_r0 = hardfault_args[0]; unsigned int stacked_r1 = hardfault_args[1]; unsigned int stacked_r2 = hardfault_args[2]; unsigned int stacked_r3 = hardfault_args[3]; unsigned int stacked_r12 = hardfault_args[4]; unsigned int stacked_lr = hardfault_args[5]; unsigned int stacked_pc = hardfault_args[6]; unsigned int stacked_psr = hardfault_args[7]; printf("\n[HardFault] Hata!\n"); printf("R0 = 0x%08X\n", stacked_r0); printf("R1 = 0x%08X\n", stacked_r1); printf("R2 = 0x%08X\n", stacked_r2); printf("R3 = 0x%08X\n", stacked_r3); printf("R12 = 0x%08X\n", stacked_r12); printf("LR = 0x%08X\n", stacked_lr); printf("PC = 0x%08X\n", stacked_pc); printf(

Hello,I have a weird problem... I currently have 10 src directories in CubeIDE, and everything compiles properly. The problem arises when I add an 11th directory (ie graphics), and then add "graphics/LVGL" to the build include path:CubeIDE will never compile any files in the "Graphics" directory.  If I move the LVGL directory to any of the previous directories (ie Core or Drivers), and redefine the include path, then CubeIDE will compile the code. Is there a restriction as to how many source code directories can be defined in CubeIDE?  The other strange thing is the "Debug" directory is in the 11th position in the list, and I was unable to move the graphics directory above Debug. Am I missing some setting or is this a restriction on CubeIDE?thanks  

Hi, I am using cubeide and I would like to enable MISRA C checking in order to develop a more robust code, thanks

Hi all, Previously, I've been adding all paths with the used header files in the Project->Properties->C/C++ Build->Settings->MCU GCC Compiler->Include paths->Include paths (-I), like this:It has been working pretty well, until it just stopped. The last thing that I've tried to add is "${workspace_loc:/${ProjName}/Firmware/MCU/Processor/FPU/FPU_Reg}" path and the compiler doesn't see header files stored there anymore. So, if I write #include "Cortex_M4_FPU_Reg.h" in source files, the build console throws out this error:but when I write #include <FPU/FPU_Reg/Cortex_M4_FPU_Reg.h>, everything is ok.Does anyone know why Include paths (-I) worked previously, but now it stopped accepting new paths?

I have a NUCLEO-L4R5ZI board with an STM32L4R5ZIT6P MCU. I have been successfully building and debugging using CubeIDE 1.9.0 with a USB connection to the onboard ST -LINK debugger. However, I've suddenly encountered a situation where after the debug load, break at main() and continue sequence, the program doesn't execute and control looks to have ended up in the system boot memory. For example, when suspending execution, the traceback shows:0x1fff16da0x1fff2c76I was wondering if anybody might have any ideas as to what could be happening.A few more data points:The Flash is being correctly programmed by the debugger. If I power cycle the board, letting it run without the debugger, the program executes properly.I can do a debugger attach on the running program and successfully debug.This happens on more than one board.This appears to be somewhat random, as I have older projects that don't fail.Thanks and best regards,Tim Butler

Hello,I went through all the SWO related topics, and it was a bit confusing for me to get it running, so I summarized the steps to have it working on a Nucleo H755.In my project I have the main clock set at 400MHz, Timer2 running at 1Hz and Debug set as "Trace Asyncronous Sw"In my main.c I have added just this:    /* USER CODE BEGIN 2 */ #define SWO_BASE (0x5C003000UL) #define SWTF_BASE (0x5C004000UL) uint32_t SWOSpeed = 2000000; // [Hz] we have 2 Mbps SWO speed in ST-Link SWV viewer uint32_t SWOPrescaler = (SystemCoreClock / SWOSpeed) - 1; /* divider value */ //enable debug clocks DBGMCU->CR = 0x00700000; //enable debug clocks //UNLOCK FUNNEL //SWTF->LAR unlock *((__IO uint32_t *)(SWTF_BASE + 0xFB0)) = 0xC5ACCE55; //unlock SWTF //SWO->LAR unlock *((uint32_t *)(SWO_BASE + 0xFB0)) = 0xC5ACCE55; //unlock SWO //SWO divider setting //This divider value (0x000000C7) corresponds to 400Mhz core clock //SWO->CODR = PRESCALER[12:0] *((__IO uint32_t *

Hello Experts,I have brought the STM32F407G-DISC1 discovery board and have a few more basic questions.1.What is the correct way to select the RAM or FLASH configuration? As of now the way i do this is :"project properties -> C/C++ Build -> Settings -> MCU/MPU GCC Linker -> General"And in the General section I manually point to the linker script, Is this the correct way? 2. When running the project from RAM configuration, during debugging i noticed that the program does not run at all, doing a little searching online,  I found out that the Vector Table Offset Register (VTOR) does not point to the correct location, it always starts assuming that the project runs from FLASH. After manually pointing it to the correct address then it works correctly! Is there any way to automate this , based on the selected .Id file?Although the setup works i get this warning now:3. When viewing live data when the debugger is running from the Live expressions tab in the debug pers

I have been running an STM project for the past month using a NUCLEO STM32F401RE. Almost every time I try to run the program for the first time that day, I get an error message that there is no ST-LINK detected. Sometimes it will connect after a while of being connected but this time there is no connection whatsoever.The LD1 light is slowly blinking red while the LD3 is lit red. I have updated to STMCubeIDE Version 1.18.0 and I have tried reinstalling ST-Link Server. I have also tried all ports on my Windows 11 with no luck.I have run my program with no issue before so I am certain it is no issue with my written program or my wiring. I have set my debugging probe to ST-LINK GDB Server which had solved the problem before but now it has no effect. Any suggestions are welcome!

Hi, I am searching for any documentation or tutorial on how to use debug tools i.e FreeRTOS, SWV etc. Thanks & Regards, YashJ    

Hello,I update my computer to MacOs 15.3.1 and I have a similar problem to when MacOs 15 arrived. The St-Link (ST-Link v3 mini) is not detected with Cube IDE (CubeIDE v. 1.17.0).It worked fine in MacOS 15.1.1I've tried starting the IDE as admin and adding the link's path to the path list, but it doesn't work. (https://community.st.com/t5/stm32cubeide-mcus/stlink-server-with-macos-15/td-p/705089)On the other hand, it is well detected with STM32Programmer.I added the IDE to the development tools in the security tab of the computer settings, just in case the problem came from the fact that apple could have changed the security rules, but that didn't solve the problem. 

hi I recently bought a Surface Laptop 7. The CPU is Qualcomm's Snapdragon. I installed stm32cubeide for testing, but I have a problem where st-link is not installed.This is a screen capture of the error message.I'm looking for a solution but haven't found one yet. Please tell me how to solve it.

Hello,I need to download some floating point arrays from STM32CubeIDE (v1.17.0).  As understood, the only way to do this is to bring the array up in a Memory Browser window, and then select Export, to a file.  Since this is in byte format, I then post-process the data with a script, to get the floating point numbers.  But the download to file takes pretty long, on the order of 3 to 5 minutes for an array of size 8192.  Am I doing something wrong, or approaching the data save incorrectly, or is that just the amount of time STM32CubeIDE takes to write to a file?Regards,RobertP.S.  Side question, will STM32Cube IDE ever support saving data to a file in its original format?, i.e. float

Hey I have a stm32f722RE that is supposed to receive CAN messages via through the canbus and active output pins via timer pins.It worked fine for some months but now its jumping to the hardfault and mem handler manager out of nowhere.Its a custom board and I have nreset connected to gnd.What I also notted is that during operation the debugger starts losing connection to my pc and then the board stops working/resets itself and then gets stuck at some handler or just jumps to handler directly.Ive attached the code,and a print of the debugger during error and the schematic of the microcontroler.Ive disconnected basically everything else that were not vital and could potencially cause an error,like sensors inputs and other outputs.Ive also checked the adress 0x08000DF8 via stm32cube programmer and it seemed fine. 

Hello,I am using the Nucleo-STM32F411RE development board, I have enabled SWV and configured it as per the instructions. But, Getting error saying below."Failed to Enable SWV.SWV will be disabled for this debug session." I am not sure, What is missing. I have followed all the instructions mentioned.Please find the attached detailed configuration and error message snapshots.Thank you!!Akash 

we are using the microcontroller stm32h503rbt6 & the IDE is STM32CubeIDE. We would like to configure DMA for I2C1 however when we go to the settings of GPDMA1/GPDMA2 then a warning(attached herewith) appears which disallows us to configure the DMA. So please suggest as to how to configure DMA for I2C1 communication

You may set in eclipse settings to have makefile generated with not expanded variables.It is very helpful when you had a project as part of bigger one and need to build it using makefile outside od IDE.There is a bug which leads to full paths in makefile, which leads to problems with placing makefile in repository.Other people in project would have to manually correct the makefile after every change.Example:# Tool invocationsFK743M2.elf FK743M2.map: $(OBJS) $(USER_OBJS) /mnt/home/trzeci/STM32CubeIDE/FK743M2/STM32H743IITX_FLASH.ld makefile objects.list $(OPTIONAL_TOOL_DEPS)arm-none-eabi-g++ -o "FK743M2.elf" @"objects.list" $(USER_OBJS) $(LIBS) -mcpu=cortex-m7 -T"/mnt/home/trzeci/STM32CubeIDE/FK743M2/STM32H743IITX_FLASH.ld" --specs=nosys.specs -Wl,-Map="FK743M2.map" -Wl,--gc-sections -static --specs=nano.specs -mfpu=fpv5-d16 -mfloat-abi=hard -mthumb -Wl,--start-group -lc -lm -lstdc++ -lsupc++ -Wl,--end-group@Echo 'Finished building target: $@'@Echo ' ' As you can see - there is full

I have a problem when typing code on stm32cube ide on macos. For example, when I type the word int, there will be a blue underline under int. If I press enter or space, the blue underline will disappear. I press enter again and it will go to the next line and the word int will not be deleted. And if the blue underline is lost, I can move the mouse to another line normally without losing the word int. If there is still a blue line, when I move the mouse to another line, the word int will be deleted. The same goes for deletion. When I finish writing the word int and press delete immediately, the first letter in the word int, the letter i, will be deleted. All the commands or documents I write in here have these 2 errors. If anyone has this problem, please help me.Thank you!

Newcomer to CubeIDE. When I set the ADC parameters for fixed sequencing, i.e. not fully configurable, some initialization code is generated for watchdogs 2 & 3 (see below). I don't want to use analog watchdogs or have to edit the main.c file manually. Is this a bug, or is there some way to alter this behaviour? Only watchdog 1 seems to have an enable check box. I'm using STM32CubeIDE Version: 1.18.0, Build: 24413_20250227_1633 (UTC) on Linux. /** Configure the WatchDogs 2 */ AnalogWDGConfig.WatchdogNumber = ADC_ANALOGWATCHDOG_2; AnalogWDGConfig.WatchdogMode = ADC_ANALOGWATCHDOG_SINGLE_REG; if (HAL_ADC_AnalogWDGConfig(&hadc1, &AnalogWDGConfig) != HAL_OK) { Error_Handler(); } /** Configure the WatchDogs 3 */ AnalogWDGConfig.WatchdogNumber = ADC_ANALOGWATCHDOG_3; if (HAL_ADC_AnalogWDGConfig(&hadc1, &AnalogWDGConfig) != HAL_OK) { Error_Handler(); }

I am working on STM32F103 for a project with CAN. While working I set the CAN Test mode to Loopback in the ioc file, afterwards I set the test mode back to normal mode. but this change was not updated in the main.c file. In main.c file, the line in MX_CAN_Init(void) function still is as following. hcan.Init.Mode = CAN_MODE_LOOPBACK;  I cleaned the project and then again built the project, still it is same, I tried to change the test mode multiple times, but every time it asks if code should be generated and I select yes, still the code is not changing. Why is this happening? CAN configuration:Generated code static void MX_CAN_Init(void) { /* USER CODE BEGIN CAN_Init 0 */ /* USER CODE END CAN_Init 0 */ /* USER CODE BEGIN CAN_Init 1 */ /* USER CODE END CAN_Init 1 */ hcan.Instance = CAN1; hcan.Init.Prescaler = 16; hcan.Init.Mode = CAN_MODE_LOOPBACK; hcan.Init.SyncJumpWidth = CAN_SJW_1TQ; hcan.Init.TimeSeg1 = CAN_BS1_2TQ; hcan.Init.TimeSeg2 = CAN_BS2_
