I have a request.The complexity of the peripheral features and the peripheral registers with the inter dependent settings makes it difficult to get everything right the first time or even after multiple tries.  This involves a code generation, code compile and download just to try one different setting. This is not very efficient nor is it a good use of available resources. Would it be possible to use the STM32MX GUI as a direct controller to modify peripheral settings in real time as the micro is running? I'm working with a comparator, a timer, DMA, and DFSDM. When I try to interconnect them so the run without code, I have very little visibility to what is going on and trying out many configurations and combinations can be very time consuming.There is a lot of power in the peripherals but it is not easy to tinker and try thin

With new and fast N6 MCU comes new CubeMX package which is full of bugs and errors, I spending hours to find and solve such problems, now I cant trust cubeMX at all, every function must be checked after code generation !ADC rank must be 7, but cubeIDE generate 1: I spent a lot of time trying to enable SPI DMA, when I tried to choose DMA handle I got unknown errors in almost all enabled interfaces (I2C, SPI, UART... ), and in some way after some changes elsewhere, closing, opening .ioc file form cubeIDE, and after next try the error is gone and I finally enabled !I trying to enable LSE, but because of so

I am using STM32H755 microcontroller and STM32CubeMX V6.14.0 for my development.I am not able to set the clock frequency to 480MHz. Whenever I do so, I receive power regulator voltage scaling error.The product revision used by me is rev.V. The RCC parameter works only when the D1CPRE is set to 240MHz. And my requirement is 480MHz.Is there any solution to run the microcontroller at 480MHz. 

Hi,when looking into the schematics of the STM32H735G-DK board (MB1520B), the Ethernet-PHY is connected via RMII.Now when I configure RMII for an STM32H7 in CubeMX, the interface pins do fit properly to what is used in the MB1520B schematics - except the RX_ERR-line. According to the schematics it is connected to PB10, but when I enable PB10 in CubeMX for use as RX_ERR, it is marked in yellow with the remark "no mode".So...how do fit both things together? How can I enable RX_ERR being used in Cube MX for RMII-mode?Thanks! 

Hello.  I am trying to create a project that uses both the Nucleo GFX01M2 and SNK1M1 with the G071RB dev board. I want to configure my setup as a USB sink device. However, in STM32CubeMX I can select either the sink USBPD application, or the Touchgfx graphics application, but not both. What would be the best way to develop an application that utilizes both USBPD and TouchGFX?  Thank you. 

Hi everyone ! first time poster, hope I'm doing it right.I'm working with an STM32F107VCT and using CubeMX to generate code.I have an issue with the RTC calendar, it goes back to 0 every reset which, if I'm not mistaken, it should not on a soft reset.I've found that in the MX_RTC_Init function, the date and time are set to the default values (see the CubeMX generated code below)./** Initialize RTC and set the Time and Date */ sTime.Hours = 0x0; sTime.Minutes = 0x0; sTime.Seconds = 0x0;   if (HAL_RTC_SetTime(&hrtc, &sTime, RTC_FORMAT_BCD) != HAL_OK) { Error_Handler(); } DateToUpdate.WeekDay = RTC_WEEKDAY_MONDAY; DateToUpdate.Month = RTC_MONTH_JANUARY; DateToUpdate.Date = 0x1; DateToUpdate.Year = 0x0;   if (HAL_RTC_SetDate(&hrtc, &DateToUpdate, RTC_FORMAT_BCD) != HAL_OK) { Error_Handler(); }Removing this piece of code solves the issue but since it is not user code, it is ba

I fully appreciate that CubeMX is geared towards hobbyists and demo projects.But let's imagine for a second that someone is trying to use this software professionally.I have created a template to generate some custom code with CubeMX and it works as expected. However, in the IOC file my settings are stored as shown below:ProjectManager.TemplateDestinationPath=C\:\\path\\to\\my\\project\\cubemx\\my_project_name ProjectManager.TemplateSourcePath=C\:\\path\\to\\my\\project\\tools\\cubemx-templatesNow imagine someone else is working on this project. Maybe they have checked out the code to a different directory, or maybe they are using Linux. The IOC file is broken for them. If they fix it on their side and commit it, it will be broken for me.Please add support for setting these paths relative to the IOC file itself, so that multiple people can work on the project.By the way, I tried editing the

Thus overwriting it every time.When generating this function:/** * @brief USBD_Get_Configuration_Number * Return configuration number * class_type : Device class type * interface_type : Device interface type * @retval configuration number */ uint16_t USBD_Get_Configuration_Number(uint8_t class_type, uint8_t interface_type) { uint8_t cfg_num = 1U; /* USER CODE BEGIN USBD_Get_CONFIGURATION_Number0 */ /* USER CODE BEGIN USBD_Get_CONFIGURATION_Number0 */ /* USER CODE BEGIN USBD_Get_CONFIGURATION_Number1 */ /* USER CODE BEGIN USBD_Get_CONFIGURATION_Number1 */ return cfg_num; }CubeMX version: 6.14.0

When starting a new project in the STM32cubeIDE and selecting the STM32U073C8T6 as the microcontroller, which has 64k flash and 40k RAM, the generated linker script uses 256k flash and 32k RAM. Also the description says that this device has 256k flash.Is this a

CubeMX always generates binary semaphores with an initial count of 1 (full) in CMSIS-RTOS2, even if the user wants the semaphore to start depleted (count = 0). There is no option to set the initial count to depleted during configuration, but when generating the code, it will be with initial count of 1./* creation of myBinarySem01 */ myBinarySem01Handle = osSemaphoreNew(1, 1, &myBinarySem01_attributes); /* creation of myBinarySem02 */ myBinarySem02Handle = osSemaphoreNew(1, 1, &myBinarySem02_attributes);only way I solve it is acquiring the semaphore after creating it

In my project, I use the RTC with LSI and calibrate it by adjusting the prescaler at regular intervals (e.g., once per day). This method works well on STM32H7, but it doesn't work on STM32H5.On STM32H5, after changing the prescaler, the RTC either stops or doesn't keep correct time.Why is this not possible on STM32H5

Hi! I have a STM32N6 discovery board and I want to create an application with network support for it. Lets say simple tcp echo server. Ifound that there are no LwIP available for this board in CubeMX. Google suggests using Arure RTOS, but there are no such (X-CUBE-AZRTOS-N6) package. Instead, there are some "THREADX" and "NETXDUO" middlewares in configurator, but there are missing options to select PHY chip that is used on the board. Is it possible to build network application using CubeMX on N6?

I am using an 8 MHz external oscillator and was planning to use a PLL to increase the system frequency. However, when I open the Clock Configuration tab in CubeMX, I don’t see any option for a PLL.I’ve also shared a screenshot of the clock configuration where it’s clear that the PLL option is not available.So my question is: Does the STM32C071CBT6 microcontroller support PLL with an external oscillator?

Hi,I'm using a STM32H523CC to receive 24 bit data frames via SPI. The SPI acts as receiver-only and is configured as follows:Within my application I do not make use of the HAL-functions but have overwritten the SPI2_IRQHandler(). There I continuously read the data from the SPI RXDR register as soon as the SPI_FLAG_RXP is set. When some overflow/error-flags are set, they are cleared:void SPI2_IRQHandler(void) { #ifdef USE_IRQ const uint32_t trigger2=SPI2->SR; if ((trigger2 & (SPI_FLAG_MODF | SPI_FLAG_OVR | SPI_FLAG_FRE | SPI_FLAG_UDR|SPI_FLAG_RXP)) != 0UL) { if ((trigger2 &a

Settings:STM32CubeMX 6.14.1STM32H573VISTM32CubeIDE v1.18.1I am not quite sure, but up to my understanding the Memory Managment Tool has a bug when it comes to the "Access Permissions" settings.When RAM is set-up like this (Access Permission set to "RW by priviledged code only"):It creates an initialization code for the GTZC1 that disables priviledge checking for the SRAM:/** * @brief GTZC Initialization Function * @PAram None * @retval

I am setting up a project using CubeMX to evaluate the 67W61M1 device, using a Nucleo-F411RE. As far as I can tell the X-NUCLEO-67W61M1 needs SPI1 of the Nucleo for communication. Unfortunately, the Nucleo has SWO (PB3) where SPI1_SCK and while I see a solder bridge that can remove SWO from the STLink-OB, I do not see a way of disabling the SWO connection to PB3.I tried resetting the state of PB3 in Cube MX and then I can enable SPI, however the "SYS" module then issues a warning about a conflict with SPI1 full duplex master.Is this the correct way to configure SPI1 and Serial Debug?Sid

I would like to report a bug, I post it here as so anybody can read it.The bug concerns the GPDMA on STM32H563, but maybe it could happen on others MCUs. I wanted to use a GPDMA1 Channel from a ADC2 request, my Channel was correctly initialized, but the transfer between the ADC->DR and my buffer wasn't realized. I initialized correctly the Channel, with the correct Source and Destination addresses, in Circular Mode, from Peripheral To Memory, in Half Word size on the two sides, with destination address increment... I checked all of my configuration.Until I checked the registers themselves... The REQSEL bits in the CxTR2 register of GPDMAx weren't initiliazed, they were equal to 0 instead of 1. These bits indiquates on which hardware request the transfer is done, something we configure in STM32CubeMX and should have been done correctly at the code generation... I added so this call in the ADC configuration function :LL

On a NUCLEO-H7S3L8 I've been testing the Projects/NUCLEO-H7S3L8/Applications/USBPD from STM32Cube_FW_H7RS_V1.2.0 with cubeMX6.14.0. I use the VScode extension, so I select the CMake toolchain. I select the "copy only necessary files" in code generation.I noticed a different behaviour when I just copy the .ioc file from the example (and just select CMake) to when I use the "access to example selector" button of cubeMX. The .ioc file in the example does not specify the specific board: it has board=custom, while the one from the example selector has: BSP_IP_NAME=NUCLEO-H7S3L8 board=NUCLEO-H7S3L8. That is the only difference I see in the .ioc files.The code generated from either of these does not operate correctly. With example selector:- BSP code is added in the folder and included in CMake files.- The libraries are not referenced in CMake files. For example, all the *HAL_Driver/Src/* files are missing in

with a standard project with only threadx and bsp code added via STM32CubeMX code generates the MX_ThreadX_Init function in main.c but the BSP initialization functions are below this call.MX_ThreadX_Init actually starts the kernel task switching (unlike FreeRTOS) so it never returns ... BSP init code is never reached.Workaround is to move the BSP init code to the user block above the call to MX_ThreadX_Init in main.c.This should be fixed in MX code generation. 

Hi,I'm using the STM32H753I-EVAL2 (MCU Type: STM32H753XIHX) to develop a new product.The product will communicate to server using the LwIP (TCP Layer) + MbedTLS (SSL/TLS Layer), running over FreeRTOS environment.We want to use the latest TLS protocol standard (TLS Version 1.3).The problem is that the current version of MbedTLS (as provided by STM32CubeMX Version 6.10.0) is 2.16.2 - which does not supports TLS Version 1.3.The latest MbedTLS version is 3.5.2 (as shown in Github). My question is: when the STM32CubeMX will include the newest MbedTLS version, with TLS 1.3 support?Thanks,Asher 

(repeated post)Currently, STM32CubeMX generates CMake projects based on the ARM-GCC compiler toolchain by default. However, in modern STM32 development environments, this toolchain appears to have performance limitations and may no longer fully meet requirements.More importantly, ARM-GCC uses the newlib standard library, while the Arm Toolchain for Embedded (ATfE) uses picolibc. For resource-constrained STM32 microcontroller development, picolibc – with its significantly smaller footprint and design specifically optimized for embedded systems – is 

Hello:  I wasn't able to enable support for RTOS in USB_HOST menu in CubeMX_6.14.0 for STM32H7R3I8Kx. There is only "Disabled"  The version of STM32Cube MCU Package for STM32H7RS Series is 1.2.0    

I am currently using CUBE MX to set up the USB-CDC function of STM32F373CCT6, but I can't find the VBUS pin. I am using the onboard power supply, and I don't know if I need to use VBUS. If there is a design example for reference, it would be very grateful.

Hello,is there NUCLEO-N657X0-Q template(s) available for CubeMX GUI (IOC project) that is/are preset for XIP or LRun? (ExtMem, Loader, XSPI etc settings ready).I'm trying to build a basic blink project starting from CubeMX IOC with BSP support (that i will later use as a basic template to [easily] add some AI Models though X-CUBE-AI plugin), however, while the code generated works fine in DevBoot debug mode (running directly from RAM) i cannot make it work when i store it in the octospi flash. (both FSBL & Appli are signed). I highly suspect that i may be doing something wrong with the extMem and/or XSPI2  setup to CubeMX initial setup!I am attaching the Full project (IOC & generated code). the root project dir also contains a "SignAndLoad_All.bat" that i use for signing and uploading the extMem.a) Are there any IOC templates/projects with preset ExtMem & XSPI Connectivity settings for the NUCLEO-N657X0-Q available? (especially a XIP
