STM32CubeMX (MCUs)

Dear all,    I have encountered an strange issue. I set Usart1 Baud Rate to 115200, however, Usart1 BRR[15:4]==0x0082, which corresponds to 57600.(57600 == 120Mhz/(16*0x82)).   I also noticed that HAL_RCC_GetPCLK2Freq() returns a wrong pclk value 0x0E4E1C00(240M), but it should be 120M. The Usart1 Config and Rcc config are as follows :   

Hi,I am installing VS Code with the STM32 extension. In the settings I need to provide a path to the MX executable. But it is not anywhere on the C drive (where everything else ST is installed).I remember I installed it with/through CubeIDE, does it mean it is not an .EXE on the drive? And so perhaps I also need to install the CubeMX as standalone?Thank you

We are pleased to announce that the release 6.14.0 of STM32CubeMX is available. What is new in 6.14.0: Added the support for the STM32WBA6xxx microcontrollers and: Added the support for USBX multi-instance Added the support for the memory management tool (MMT) Added the support for the STM32WBA65I-DK1 Discovery kit and NUCLEO-WBA65RI Nucleo board Deployed the Start From Board feature on the NUCLEO-WBA65RI Improved the Power Delivery (USB PD) functionality for STM32H7Rx/7Sx and STM32N6 microcontrollers by upgrading the USB PD library core to v5.3.0 Adapted STM32CubeMX user interface to allow the user to: Access the Compare Projects utility from the home page and compare two existing projects Compare two existing projects without save down Improved the build process with CMake Update the RIF panels to indicate the peripherals that are not supported by STM32MP2 products. Removed the Secure Manager boot path Main fixed issues in 6.14.0: Refer to the STM32 microcontroller wiki at:http

Very late response, but I was having the same issue with cubemx v6.14.0 working with stm32h755zit3u on a nucleo-h755zi dev-board and using stm32cubeIDE v1.8.0.  After some investigation, cubemx is not updating the links .project file in cubeIDE.  The .project file is just xml, so manually edit it and add links to stm32h7xx_hal_adc.c and stm32h7xx_hal_adc_ex.c (substitute h7xx for correct uC version for your project). Possibly, I have set up something incorrectly in cubeMX - I'm just learning ADCs.  But, re-hitting the "generating code" button in cubeMX did not wipe out the my .project edits.  So, at least a temporary fix.  

Hi,   I'm working on an STM32U595 and there is a code generation problem in the function `void PWR_S3WU_IRQHandler(void)` where when you have multiple wake up pins and S3WU interrupt enabled : /* USER CODE END PWR_S3WU_IRQn 0 */ HAL_PWREx_S3WU_IRQHandler(PWR_WAKEUP_PIN2 || PWR_WAKEUP_PIN5 || PWR_WAKEUP_PIN6); /* USER CODE BEGIN PWR_S3WU_IRQn 1 */   But the generated code should be: /* USER CODE END PWR_S3WU_IRQn 0 */ HAL_PWREx_S3WU_IRQHandler(PWR_WAKEUP_PIN2 | PWR_WAKEUP_PIN5 | PWR_WAKEUP_PIN6); /* USER CODE BEGIN PWR_S3WU_IRQn 1 */   This creates a big problem because as soon as you define several wake up pins in stop mode 3, it no longer works.   Best regards, Steven

The linker scripts generated by MX for the STM32U5G9xx devices are reporting 2528 Kbytes of RAM. These are 3MB devices so I would expect there to be 3008 Kbytes of RAM when ECC is disabled. MX output to STM32U5g9xx_FLASH.ld:/* ** Abstract : Linker script for STM32U5G9xJ Device from STM32U5 series ** 4096Kbytes FLASH ** 2528Kbytes RAM */ /* Memories definition */ MEMORY { RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 2496K SRAM4 (xrw) : ORIGIN = 0x28000000, LENGTH = 16K FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 4096K } See Table 2 and page 27 of https://www.st.com/resource/en/datasheet/stm32u5g9vj.pdf On a somewhat related note, MX in Linux wasn't generating the linker scripts so I had to use a Windows computer to generate them. 

I am using a STM32N6570-DK board and I can't understand how to configurate the FSBL, Application, and the External memory stuff in Cubemx. Can anyone describe how to use and configurate these three options?

When generating a CMake project using NetXDuo with lan8742 as phy driver and DHCP Client enabled, the necessary includes for the lan8742 bsp component and the dhcp client addon are missing from the CMake build configuration.However when using the STM32CubeIDE as the export target in CubeMX, the includes are present in Project --> Properties --> C/C++ Build --> MCU GCC Compiler --> Include Paths. Building works just fine aswell.

In my project, i use STM32F070CBT6 microcontroller and i use STM32CubeIDE to set up my project. At first i did not place all pins which i use in this project if i get an error. I define only SCL and SDA pins for PB14 and PB13 pins for that purpose. I did not get any error but when i try to generate code, it did not generate anything. I am confused about what i did. I am waiting for your help.

Using STM32CubeMX 6.14.0 with H7 package 1.12.1.When Ethernet is set up with number of RX descriptors set to 16, the default LWIP ethernet driver rx buffer pool overflows. This is caused by during startup, HAL_ETH_Start_IT calls ETH_UpdateDescriptor.  This allocates all 16 rx descriptors to a slot in the rx pool.  Entirely consuming the pool.Upon first packet receive, via ethernet_input, low_level_input, EHAL_ETH_ReadData, ETH_UpdateDescriptor is called to allocate 1 more descriptor.  This allocation fails.Some time later a descriptor is freed, next received packet, a descriptor can be allocated.  Every second received packet fails allocation.This behavior should either be prevented by the driver code, or a warning generated in STM32CubeMX that it wont work.It appears setting ETH_RX_BUFFER_CNT to 17, is enough to alleviate the issue.  My buffers are all 1568 bytes so can fit a full ethernet packet, so each receive fits in a packet.  But for small

I'm trying to create a new STM32H747 project in STM32CubeMX and right away I'm running into an odd issue - I can't turn off FreeRTOS and FatFS. It reports that "peripheral FreeRTOS_M7 could not be removed from context Cortex M7 as it's forced for this peripheral."I need to use Azure RTOS in this project, and I can enable its packages for the project, but I still can't disable FreeRTOS. I had no trouble with this in my last STM32H743 project, so I'm a little puzzled. Is there some setting I'm missing?FYI, I only need the RTOS on the M7 core. 

Hi guysI can't find threadx support for F4, F7 and H7, it's only available for C0 series. According to this post, and my google. It should support most stm32 MCUs. What can I do to enable threadx support for these MCUs? 

In my project I have FreeRTOS enabled, which occupies SysTick and Time increment is handled by TIM1. I also want to use basic timer as TIM6.However, I don't want them both processed in weak redefined void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim)Thus, I enabled register callback for TIM in CubeMX -> advance settings -> register callbacks.The generated code appears in stm32f4xx_hal_timebase_tim.c and looks as following:HAL_StatusTypeDef HAL_InitTick(uint32_t TickPriority) { RCC_ClkInitTypeDef clkconfig; uint32_t uwTimclock = 0U; uint32_t uwPrescalerValue = 0U; uint32_t pFLatency; HAL_StatusTypeDef status; /* Enable TIM1 clock */ __HAL_RCC_TIM1_CLK_ENABLE(); /* Get clock configuration */ HAL_RCC_GetClockConfig(&clkconfig, &pFLatency); /* Compute TIM1 clock */ uwTimclock = 2*HAL_RCC_GetPCLK2Freq(); /* Compute the prescaler value to have TIM1 counter clock equal to 1MHz */ uwPrescalerValue = (uint32_t) ((uwTimclock / 1000000U) - 1U);

Hi,    After configuring NUCLEO-H753ZI using CubeMX, I clicked "GENERATE CODE", the process started for a few seconds, then totally frozen with no progress, no end.    What I should do now? Thanks,Rong  

 I am using Arduino GIGA R1 to build an deploy model from simulink. While building model I am getting " Error:Peripherals in STM32CubeMX project are not configured to generate a global initialization function. To generate a global initialization function open STM32CubeMX project > Project Manager > Advanced Settings > Generated Function Calls and disable "Visibility(static)" option for all the peripherals.Suggested Actions:Click 'Open' to open project in STM32CubeMX." from simulink. Although I followed the steps mentioned in the build summary I am still getting the same error. Please help.  

 Hi ST-Community, I have a problem with my STM32CubeMX: The pin context assignment for STM32WL55JCI7 is missing. Does anyone have the same problem and know how to fix it? (No generated code for GPIOs) Many thanks in advance for your support! Kind regards,Philipp

I've switched to mac and like any responsible adult all of my projects are handled by git. But when I generated the code with CubeMX it was a little confusing to see so many files have changed. A quick search brought me to this topic without any answer:https://community.st.com/s/question/0D50X00009XkgaG/cubemx-line-ends-in-generated-codeThe solution is that CubeMX uses a repository of files in the background (which have DOS line ending) and it appends different files together to generate your code. So the easy way to fix the problem is to do the following steps:`brew install dos2unix`find where `STM32Cube` directory is (mine was under home)Go to `STM32Cube/Repository/STM32Cube_FW_xx_xxxx` which is the firmware version you use. If you're not sure of it, open your CubeMX go to Project Manager, on the left select Project and under "Mcu and Firmware Package" find the firmware version. Running the commands at Repository directory fixes all the firmwares.Open a terminal at the firmware repos

I've discovered that when I configure the TIM2 timer to ‘input Capture direct mode’ for any port A input pin it doesn’t add the necessary line in  HAL_TIM_Base_MspInit() to configure the pin to alternate mode, namely the following line is missing in HAL_TIM_Base_MspInit():‘GPIO_InitStruct.Alternate = GPIO_AF1_TIM2;’The line is present when port B is selected, so that works.My work-around (for PA0) is to add the line to the main code:GPIOA->AFR[0] |= (1U << GPIO_AFRL_AFSEL0_Pos);I'm using Stm32CubeMX v.6.14.0 with STM32Cube_FW_U0_V1.2.0

Dear @KDJEM.1 ,I have seen that in STM32CubeIDE Version: 1.16.0 this issue is solved if the "Generate peripheral inizialization as a pair of '.c/.h' files per peripheral" is NOT selected in the ".ioc". Otherwise, the problem keeps there and "HAL_PWREx_EnableVddUSB()" is not called.Here, you can see the code if the option is NOT selected:    void HAL_PCD_MspInit(PCD_HandleTypeDef* hpcd) { RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0}; if(hpcd->Instance==USB_DRD_FS) { /* USER CODE BEGIN USB_DRD_FS_MspInit 0 */ /* USER CODE END USB_DRD_FS_MspInit 0 */ /** Initializes the peripherals clock */ PeriphClkInitStruct.PeriphClockSelection = RCC_PERIPHCLK_USB; PeriphClkInitStruct.UsbClockSelection = RCC_USBCLKSOURCE_HSI48; if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInitStruct) != HAL_OK) { Error_Handler(); } /* Enable VDDUSB */ HAL_PWREx_EnableVddUSB(); /* Peripheral clock enable */ __HAL_RCC_USB_CLK_ENABLE(); /* USB_DRD_FS interrupt Init */ HAL_

I tried to use cmake with CubeMx but I cant make RTT works.Error:multiple definition of `_write_r'; /usr/lib/gcc/arm-none-eabi/13.2.0/../../../../arm-none-eabi/lib/thumb/v7-m/nofp/libc_nano.a(libc_a-writer.o):/build/arm-none-eabi-newlib/src/build-nano/arm-none-eabi/thumb/v7-m/nofp/newlib/../../../../../../newlib-4.3.0.20230120/newlib/libc/reent/writer.c:45: first defined hereRTT needs to define _write_r but seems already define.If I comment this line from the gcc tool chain it solves the problem:set(CMAKE_C_LINK_FLAGS "${CMAKE_C_LINK_FLAGS} -Wl,--start-group -lc -lm -Wl,--end-group")Before I used my custom cmake this way:```target_link_options(${EXECUTABLE} PRIVATE-T${MCU_LINKER_SCRIPT}${CPU_PARAMETERS}-Wl,-Map=${CMAKE_PROJECT_NAME}.map--specs=nosys.specs-Wl,--start-group-lc-lm-lstdc++-Wl,--end-group-Wl,--print-memory-usage)```and have no problem so I don't really understand why.Also tried -fcommon it does nothing.

Hi everyone,I noticed that CubeMX 6.14.0 ignores the octospi parameter settings. I created a new project for the NucleoU5A5 board, configured Octospi1 with a clock prescaler of 99. I notice the following behaviorGenerated code (CubeIDE) has a prescaler value of 1Next time I open the IOC file, the Octospi prescaler is back to 1I didn't check other settings. I have attached my ioc file Kind regards,Timon Zijnge 

MCU:STM32U585xxEnv:ThreadX + USBX + FileXI want to use USBX add my own class type, but I'm already have 3 classes, HID, MSC and CDC ACM, it means 4 classes after added my own.In file (ux_device_descriptors.h) have a define (USBD_MAX_SUPPORTED_CLASS  3U), this value determined the (tclasslist) array size, also the framework max class, can not be changed by user define or STM32CubeMX(no option find).If I change this define, it will be overwrite by STM32CubeMX when generated code. How can I do this correctly?

In many cases, especially for middleware, it may be necessary to extend the code generated by CubeMX.Since not all files have sections that are untouched by the code generator or some places inside a file are missing those user code sections, I'm often in the need of a feature that would allow to add my own sections by adding a comment such as /* USER CODE BEGIN */ /* USER CODE END */ to my source file. Unfortunately, those sections are overwritten as soon as the code generator gets triggered again.Would it be possible to add this feature?How does the code generator currently handle those sections anyway if not looking for the specific comments (since adding my own user code comments does not work)?

The GPIO clock is the only code that seemed to be generated under the initialization function. the other necessary code such as the following was not created. GPIO_InitTypeDef GPIO_InitStruct; GPIO_InitStruct.Pin = GPIO_PIN_8; GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP; GPIO_InitStruct.Pull = GPIO_NOPULL; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW; HAL_GPIO_Init(GPIOC, &GPIO_InitStruct);In the setup GUI I had selected the pin PC8, and set it to a GPIO_Output yet the above code was not generated.
