STM32CubeIDE (MCUs)

Hello STM32 Community,I'm working with the STM32L4S5VIT6 microcontroller and implementing low power functionality using STOP2 mode. Setup Summary:I use a GPIO button (external interrupt) to enter STOP2 mode on the first press.On the second press, I attempt to wake up the MCU and call low_power_off() to reinitialize peripherals and resume operation.I’m using MSI as the system clock (no PLL), and STOP2 mode is entered with HAL_PWREx_EnterSTOP2Mode(PWR_STOPENTRY_WFI);.Behavior in Debug Mode:Everything works as expected:First button press → enters STOP2 via low_power_on().Second press → wakes up and executes low_power_off() successfully. Problem in Release Mode:First button press → MCU enters STOP2 mode.Second button press does not wake up the MCU as expected.It seems the EXTI interrupt is not firing in release mode, or the wakeup source isn't triggering properly. What I've Checked:EXTI configuration seems correct.Wakeup pin is properly pulled up, and configured for falling

Hi, I downloaded the STM32CubeN6 for my STM32N6570-DK, version 1.1.0. from https://www.st.com/en/embedded-software/stm32cuben6.html. I noticed that there is a newer version 1.1.1 available, but that is a patch, not a package. I haven't found an explanation how that patch should be applied. Asking that because automatically generated template code with 1.1.0. won't run successfully. DK crashes when calling  HAL_ICACHE_ConfigAssociativityMode() Any advice to share is appreciated. Cheers, heke  

Good afternoon community,I am trying to capture the frequency which is given by wave-form generator and i am able to capture that,But issue is i am not able to capture when it is face the underflow condition and it will not working properly.please suggest which changes need in code. I am sharing all details here for your reference.Here is callback function while (1){/* USER CODE END WHILE */ /* USER CODE BEGIN 3 */if(is_capture_done == 1){if (input_captures[1] > input_captures[0]){capture_difference = input_captures[1] - input_captures[0];}else if (input_captures[1] < input_captures[0]){capture_difference = ((0XFFFF - input_captures[0]) + input_captures[1]) + 1;}// calculate the frequency by capture differencefloat refClock = (HAL_RCC_GetPCLK2Freq());timer2_cnt_freq = refClock / capture_difference;printf("%lf\n",timer2_cnt_freq);is_capture_done = 0;HAL_Delay(1000);}}and main function iswhile (1){/* USER CODE END WHILE */ /* USER CODE BEGIN 3 */if(is_capture_done ==

Hello,i have a project created with STM32Cube IDE Version 1.18.1 for the STM32G473CCU micro-controller with 256k flash. My binary file is 180k length and the debugger launched from STM32Cube fails to program the flash because it enables the dual bank mode. The flash is programmed correctly from 0 to 128k, then the verify fails from 128k to 180k. I'm using a Segger J-LINK and this problem NEVER happens using the JFlash software. In order to re-enable the single bank flash mode i have to erase and program the flash with JFlash, then also the debugging from STM32Cube works, but only once. Why? How can i configure the Option Bytes? Leo

Hello,        I have some issues with function macros usage in my stm32cubeIDE project after importing some generated code in cubeIMX.      This issues come on the back of my work related to this topic : is there any sample for X-NUCLEO-NFC08A1 to be use... - STMicroelectronics Community   And the macro usage issues I have might be similar to the topic here Multiple "expected expression before 'do'" errors - Page 2 - STMicroelectronics Community but I could not figure out what is the issue and solution in my case in rfal_platform.h from the X-CUBE_NFC6 example I have error "expected expression before ',' for these macros:  #define platformGpioSet( port, pin ) HAL_GPIO_WritePin(port, pin, GPIO_PIN_SET) /*!< Turns the given GPIO High */ #define platformGpioClear( port, pin ) HAL_GPIO_WritePin(port, pin, GPIO_PIN_RESET) /*!< Turns the given GPIO Low */ #define platformGpioToogle( port, pin ) HAL_GPIO_T

I created a project using STMCubeMX and imported into STM IDE. All went without errors. However in the IDE, Build project is disabled. When I click on Run As.., I got the following error.How can I get the build project enabled ? This is my first time using STM IDE. Previously I used Arduino and it worked fine for my basic projects. 

The font size used for the GUI in the STLinkUpgrade utility so small it is virtually unreadable on the external 32" 4K monitor that I use with my laptop. The following shows the text size relative to code within the IDE:It's possible that this is as a result of using a 4K screen, as it looks ok when running on the laptop screen:The size stays as above if I then close the lid, even though the external screen then switches back to 4K.

Ther seems to be a problem in the STM32CubeIDE versione 1.17.0 when debugging / programming the STM32H730 chip.The Programmer returns: ST-LINK SN : 002800045553500F20393256 ST-LINK FW : V3J15M7B5S1 Board : STLINK-V3SET Voltage : 3.28V Error: Unable to get core ID Error: ST-LINK error (DEV_TARGET_CMD_ERR) 2nd connect tentative with frequency (8MHz) ST-LINK SN : 002800045553500F20393256 ST-LINK FW : V3J15M7B5S1 Board : STLINK-V3SET Voltage : 3.28V SWD freq : 8000 KHz Connect mode: Under Reset Reset mode : Hardware reset Device ID : 0x483 Revision ID : Rev Z Error: Database: There's no active configuration for this device.

I am using NUCLEO-H563ZI and am trying to implement bank swap for firmware update. I am using YMODEM to update firmware. Initially when my code is being executed from BANK 1 and after writing the new firmware at BANK 2. The code execution starts from BANK 2 successfully. But the reverse in not happening. After all the process I checked the address where I am writing the new firmware in BANK 1 and nothing was there which cause hard fault. Therefore, why the process doesn't fail initially when writing firmware at BANK 2 and it fails only when writing at BANK 1 even though the code is same. Below I have attached some files. void SerialDownload(void) { uint8_t number[11] = {0}; uint32_t size = 0; COM_StatusTypeDef result; Serial_PutString((uint8_t *)"\rWaiting for the file to be sent ... (press 'a' to abort)\n\r"); result = Ymodem_Receive( &size ); if (result == COM_OK) { if ((erase_operation==1) && (end_of_download_operation ==0)) { end_of_download_ope

I'm using STM32CubeIDE 1.18.1 and when i create a new STM32 CMake Project for a STM32U5, the generated ld file contain only half the memory.For example here what is generated in STM32U575ZITXQ_FLASH.ld:MEMORY { RAM (xrw) : ORIGIN = 0x20040000, LENGTH = 512K /* Memory is divided. Actual start is 0x20000000 and actual length is 768K */ SRAM4 (xrw) : ORIGIN = 0x28000000, LENGTH = 16K FLASH (rx) : ORIGIN = 0x08100000, LENGTH = 1024K /* Memory is divided. Actual start is 0x08000000 and actual length is 2048K */ }This doesn't happens when creating a classic STM32 project.

  Dear Sirs I am having a problem using FreeRTOS and USB on H7 series MCU. The IDE gives “Hard Fault” when I debug the project. See image below.   The environments are : STM32CubeIDE:  Version: 1.14.0, Build: 19471_20231121_1200 (UTC) Target: NUCLEO-H743ZI2 Enclosed herewith are the two “ioc” files. FreeRTOS_USB1.ioc is for the project without initialization to the USB and it is working fine. FreeRTOS_USB.ioc is for the project with the initialization to the USB and it is giving my Hard Fault.   Your help and assistance are highly appreciated. Best Regards Dr Reyah Abdula  

Hello, I'm trying to get running own external loader for CubeMX compiled with CubeIDE.I have followed this internet source to set-up envirement but without success. Because the CubeMX plugin doesn't work I tried to debug RAM-execution without CubeMX. By starting directly on target HW, the breakpount setted in Init function was served. But all nested function were not jumped-in at all. That leads to programm crash and therefor the pluging doesn't work inside CubeMX. But Plugin-selection inside CubeMX is possible, because parsing of the plugin is okay.Please can some one explain what the problem with nested functions when executed from RAM. Thanks to every one. 

Correct me if I'm wrong, but it seems that ITM_SendChar() is blocking on the character transmission. Has anyone attempted to compensate for this or do people just put up/move to a UART?At this point all I can think of is to implement a FIFO queue and tie a timer interrupt to it to fake the equivalent of Transmit Data Register Empty. Thoughts?FYI I'm using an STM32F411 in CubeIDE and Keil uVision connected via ST-Link/V2.

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 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 ?

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
