STM32CubeMX (MCUs)

Hi all!Thanks again for the help so far.Just another question, is it possible (or normal?) when creating a pack to have it insert snippets of code into main.c just like the code snippets that get inserted by the cube when you change peripherals etc? Thanks again. 

Hello,I am developing on the STM32H7A3ZGT and I am trying to use both OCTOSPI instances that are on the microcontrollerI am able to use both of them separately (only initialising one instance) but when I do both the initialization only the last initialised instance is working fine.I get no errors codes from any function on the first octospi instance that is initialised, but the data that I receive are all "0".If I switch the init order it switches the instance that is working.I am working on cube MX V6.6.1 but I tried generating a new project on the latest version and I get the same resultTank you for your help,Best regardsAugustin

im using stm32h743zi2 ethernet with udp . so i generated code and running in Kiel and ping working fine . BUT  how to  i re initialize lwip at run time .i tried to reinitialize at run time but the ping is stopping after reinitializing . any body does this , hope u suggest me . thanks 

hello,I have a very simple question, I have asked a FAE,but not solved.I am using STM32CubeMX to config a project. I used an external 32.768khz crystal. I want to set the RTC clock to the external crystal. below is my setting.I think i have enabled HSE and LSE. the clock to RTC is fixed to LSI RC, but I want to use LSE, not LSI, how can I setting? Thanks,dqsh06 

Hi,      My one microsecond timer configured by CubeMx running on NUCLEO-C031C6 (STM32C031C6) is 3 times slower than it should be. The code is attached below.      the call "delay_us(60000000);" takes 3+ minutes to complete - it should be done in one minute.      The LL timer (TIM3) init and interrupt code is generated by CubeMx..The system clock is 48 MHZ in CubeMx.       How to fix it?       Thanks,      Rong   void MX_TIM3_Init(void) { LL_TIM_InitTypeDef TIM_InitStruct = {0}; /* Peripheral clock enable */ LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_TIM3); /* TIM3 interrupt Init */ NVIC_SetPriority(TIM3_IRQn, 0); NVIC_EnableIRQ(TIM3_IRQn); /* USER CODE BEGIN TIM3_Init 1 */ /* USER CODE END TIM3_Init 1 */ TIM_InitStruct.Prescaler = 0; TIM_InitStruct.CounterMode = LL_TIM_COUNTERMODE_UP; TIM_InitStruct.Autoreload = 48; TIM_InitStruct.ClockDi

This bug is present in ethernetif.c files for lwIP generated by CubeMX for the newer reworked ETH drivers.ProblemWhen using CMSIS-RTOSv2, CubeMX generates the following code in the function low_level_output(): pbuf_ref(p); HAL_ETH_Transmit_IT(&heth, &TxConfig); while(osSemaphoreAcquire(TxPktSemaphore, TIME_WAITING_FOR_INPUT)!=osOK) { } HAL_ETH_ReleaseTxPacket(&heth); The TxPktSemaphore is initialized with both maximum and (wrongly) initial count of 1. Because the semaphore count is already 1, the osSemaphoreAcquire() call returns immediately and the HAL_ETH_ReleaseTxPacket() can release the packet before the transmission has actually been completed. While the Tx complete interrupt happens after the osSemaphoreAcquire() call, the code continues running in this crippled mode, corrupting packets and driver/stack state.When the Tx complete interrupt happens before the osSemaphoreAcquire() call, the osSemaphoreRelease() call in the Tx complete interrupt tries to increa

I have to interface an STM32U575 microcontroller with a very specialized SPI device for which the market offers no alternatives. According to the spec sheet, the chip select must be pulsed between every 2 bytes, for at least 154 ns. I have to read 34 bytes from this chip every 50 us. The chip allows a maximum SPI clock rate of 24 MHz.Although I can talk to the device, the SPI controller seems to not be fast enough.SPI Configuration:However, in my attempts to speed these transactions up, I have ditched the HAL for writing/reading to/from the SPI peripheral during the steady state program flow.SPI functions:void SPIM3_INIT(int len) { SPI3->CFG2 &= ~SPI_CFG2_COMM; // Set Full-Duplex mode SPI3->CR2 = len >> 1; // Set the number of data at current transfer SPI3->CR1 |= 1; // enable }   int8_t SPIM3_XFER(uint8_t *txb, uint8_t *rxb, int len) { volatile uint16_t *ptxdr_16bits = (volatile uint16_t *)&SPI3->TXDR; volatile uint16_t *prxdr_16bits = (volatile uin

Hi, I want to implement Free RTOS on SWTM32U575. When I am trying to configure it in the middleware but there is no options to enable Free RTOS. Is there a way to way to enable it ?

Hi, I have a NUCLEO-H7S3L8 and I think there is an addresses mistake in the .svd files and potentially other hardware description files.You can reproduce and see the mistake if you setup the SAI1_A and SAI1_B on CubeMX, generate the code and debug the program, you will see in the SFR widget of STM32CubeIDE (the .svd file) that it's the SAI2 registers configured instead.It also affects the CubeMX configuration of SAI, we can't set SAI1_A on Master and SAI1_B on Slave synchronous which is very annoying (image below). I'm not sure if it's the right place to report this, but I would really appreciate if you follow this issue on the right ST team.Thanks.

I was able to successfully install and launch CubeMX. However, I cannot download the packages. In my case I need the STM32CubeG0 firmware packages. When I download it manually and select "From Local" I get "Failed to create temporary directory". In ~/STMCube/Repository write permissions are granted. If I start CubeMX as root, then everything works. But I don't want to start CubeMX always as root. How do I fix this problem?

Hi all,I'm struggling for some time to get the CAN bus of my Evalboard (STM32H745I-DISCO) working. No matter how I configure the CAN bus in CubeMX, I always end up in the following error area and I don't know why: /* Check that the Tx FIFO/Queue has an allocated area into the RAM */ if ((hfdcan->Instance->TXBC & FDCAN_TXBC_TFQS) == 0U) { /* Update error code */ hfdcan->ErrorCode |= HAL_FDCAN_ERROR_PARAM;   return HAL_ERROR; }First, my FDCAN initialization looks like this:static void MX_FDCAN1_Init(void) { hfdcan1.Instance = FDCAN1; hfdcan1.Init.FrameFormat = FDCAN_FRAME_CLASSIC; hfdcan1.Init.Mode = FDCAN_MODE_NORMAL; hfdcan1.Init.AutoRetransmission = ENABLE; hfdcan1.Init.TransmitPause = DISABLE; hfdcan1.Init.ProtocolException = DISABLE; hfdcan1.Init.NominalPrescaler = 12; hfdcan1.Init.NominalSyncJumpWidth = 1; hfdcan1.Init.NominalTimeSeg1 = 5; hfdcan1.Init.NominalTimeSeg2 = 2; hfdcan1.Init.DataPrescaler = 12; hfdcan1.Init.DataSyncJumpWidth = 1; hfdc

Hello,I tried exporting the symbol for STM32F733IET6 along with the pin naming through stm32cubemx(V6.10.0) but all i get is empty boxesI am using kicad v7. It's not a kicad problem because i've imported symbols recently with no issues.  Am i doing something wrong?

hello! I start this post because i have created a new project with CUBEMX 6.12.0 and i am having some issues. When I generate code without THREAD X activated, the generation is completed without any error. However, when I add the thread X option (see .ioc file), the generation process gets stuck in "copying files" I am developing a project for an STM32H563xxx HW and I have updated all the necessary libraries such as:ThreadX v6.2.0 (I cannot upgrade it to the 6.4...)FW package manager: STM32Cube FW_H5 V1.3.0And i am running the software on a WIndows 10 laptopHow is that? What can I do to solve this problem.

I am using STM32CUBEMX 6.6.1. When trying to export a Kicad model, the model turns out empty without any Pins.

Hi there, I have been having a lot of issues exporting the stm32h753 symbols to kicad. In fact I can export the files, but there is no pins when I select it in kicad. Just a rectangle. I tried looking to see if the pins were hidden, but no, it doesn't look like that's the issue. Thanks!

With the newest CubeMx version 6.11.x, when selecting oversampling, a ratio is being set, and this ratio is a define, which are in "ADC_VER_V5_V90" that is not being set when a new project is created. #if defined(ADC_VER_V5_V90)#define ADC3_OVERSAMPLING_RATIO_2 (LL_ADC_OVS_RATIO_2)#define ADC3_OVERSAMPLING_RATIO_4 (LL_ADC_OVS_RATIO_4) #define ADC3_OVERSAMPLING_RATIO_8 (LL_ADC_OVS_RATIO_8) #define ADC3_OVERSAMPLING_RATIO_16 (LL_ADC_OVS_RATIO_16) #define ADC3_OVERSAMPLING_RATIO_32 (LL_ADC_OVS_RATIO_32) #define ADC3_OVERSAMPLING_RATIO_64 (LL_ADC_OVS_RATIO_64) #define ADC3_OVERSAMPLING_RATIO_128 (LL_ADC_OVS_RATIO_128)#define ADC3_OVERSAMPLING_RATIO_256 (LL_ADC_OVS_RATIO_256) #define ADC3_OVERSAMPLING_RATIO_512 (LL_ADC_OVS_RATIO_512) #define ADC3_OVERSAMPLING_RATIO_1024 (LL_ADC_OVS_RATIO_1024)#endifThis gives an error in the adc.c file as:hadc1.Init.Oversampling.Ratio = ADC3_OVERSAMPLING_RATIO_4;The "ADC3_OVERSAMPLING_RATIO_4" is missing/undeclared.

When I try to generate code I am getting "eclipsec" error pop=up referring me to a log file. The file content is attached below. I have uninstalled all the STM32 applications and reinstalled just MX 6.12.0, but error is still here. !SESSION 2024-07-15 17:37:34.297 -----------------------------------------------eclipse.buildId=unknownjava.version=17.0.11java.vendor=Eclipse AdoptiumBootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=en_USFramework arguments:  -application com.st.stm32cube.ide.common.services.mx.rcpApp -rmiServerPort 8435 -projectUpdate -buildType exec -src cube -cubeScratchFile C:\GIT_REPS\PROJECTS\JefCore\SPLIT\FIRMWARE\Simulator\F3discovery\MX\mx.scratchCommand-line arguments:  -os win32 -ws win32 -arch x86_64 -application com.st.stm32cube.ide.common.services.mx.rcpApp -data C:\Users\panasyuk\.stm32cubeide\.workspace_5374180911736407778 -rmiServerPort 8435 -projectUpdate -buildType exec -src cube -cubeScratchFile C:\GIT_REPS\PROJECTS\JefCore\SPLIT\

Hi All,I am working on setting up a pipeline on Jenkins for building the STM32 platform-based projects. A .ioc file is used to generate the project using the STM32CubeMX command, which is run in a Docker container (from a docker image I built based on ubuntu) in the pipeline script. Here's the command used to invoke STM32CubeMX:  java -jar <path_to_CubeMX>/STM32CubeMX -q <scriptfile> Everything works fine when I use the same image and run a container on my local machine and execute the command inside the container; however, when I pull the image and execute it inside the Docker container in my pipeline using the docker.image(DOCKER_IMAGE).inside(){ ---cmd--- } I see the following error in the Jenkins log file as shown below: 2024-07-12 11:31:08,156 [ERROR] ProjectBuilder:2169 - java.io.IOException: Function not implemented at sun.nio.ch.FileChannelImpl.transferFrom0(Native Method) ~[?:?] at sun.nio.ch.FileChannelImpl.transferFromDirectlyInte

Hello, I would like to report a bug on USB CDC middleware generated from CubeMX 6.11. When I use it in Debug build, everything works as expected. Once I switch to Release, the compiler optimizes out the serial number.  I use official VScode extention with Cmake to build the FW.Without a serial number at USB device, Windows fails to recognize that anything is connected. It works in Linux only. I have the same issue happen at STM32F411 and STM32L433. The solution was to add initalization to 3 lines in USB_DEVICE\App\usbd_desc.c uint32_t deviceserial0 = *(uint32_t*)DEVICE_ID1; uint32_t deviceserial1 = *(uint32_t*)DEVICE_ID2; uint32_t deviceserial2 = *(uint32_t*)DEVICE_ID3; I hope this helps someone and the STM may fix it. No support is needed.Thanks.

Hello STM Team,I am using the STM32H723ZG board with MATLAB STM embedded coder support packages and I configured the STM32H7 MCU peripherals for ADC1,ADC2 and ADC3,PWM and GPIO, i can see the signals on the GPIO output pins and PWM when I don't use the multiple configuration's in the ADC but When I configure the Multiple channel ADC configuration, I could not see any signal on the GPIO and PWM pins,  Can i know is there any issue with DMA configuration with Multiple channel ADC?Attached the multiple channel configurations for ADC in the picture.BRVenkat

In `HAL_I2C_MspInit()`, `I2C4_ER_IRQn` and `I2C4_EV_IRQn` are switched.In CubeMX, ticking an Event interrupt for I2C4 generates an Error interrupt, and vice versa. The same behavior was observed in STM32CubeIDE 1.11.0.

Hello.My STM32CubeMX version is 6.12, and I have chosen to create the project through the CMake toolchain.But when I make the project directly, I encounter the problem that target CPU does not support ARM mode. How can I solve it?I didn't change anything in CMakeLists.txt 

It is a common requirement to have an area of RAM that is not cleared or otherwise initialised by the startup code; eg,https://community.st.com/t5/stm32cubeide-mcus/how-to-make-keep-ram-value-after-software-reset/m-p/96132https://community.st.com/t5/stm32cubeide-mcus/how-to-port-no-init-iar-directive-with-to-gcc-compiler-please/m-p/661867to mention but two.Currently, this means making manual edits to the linker script - which get overwritten with every 'Generate'. :frowning_face:So how about adding a "noinit section" option in the Project 'Linker Settings':  Or making the generated linker script have areas which will not get overwritten - as in the generated 'C' code. (I've tagged this as 'Bug Report' because the forum insists on having a tag, but none of the available tags is relevant! 'Bug Report' seems the least worst.)
