Hi,Iam using a STM32F746 DISCO Board to use SDMMC in a TOUCHGFX Application but Iam not able to get past if(f_mkfs((TCHAR const*)SDPath, FM_ANY, 0, rtext, sizeof(rtext)) != FR_OK) function. It gives error here. Even If I comment this section and reach fopen command it returns FR_DISK_ERR. However When I simply run the standalone SDMMC example ,it works and writes data to SD card.Why is that the same example does not work with Touchgfx application?The only difference I could see is of Clock speed between two applications. One is at 50Hz & other is at 48Hz.Im Prototyping my project on disco board before I go into custom design. Kindly help!!

Hello, I use 25 MHz quarz (XRCGB25M000FAN00R0) together with 5.6 pF load capacitors. When I configure clock to 170MHz my program stuck here: while (READ_BIT(RCC->CR, RCC_CR_PLLRDY) == 0U). When I configure clock to 168.75 MHz, then everything work corectly.  Can someone explain how this problem could be solved? Thank you for answers. Best regards   Configuration for 168.75MHz clock:   void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; /** Configure the main internal regulator output voltage */ HAL_PWREx_ControlVoltageScaling(PWR_REGULATOR_VOLTAGE_SCALE1_BOOST); /** Initializes the RCC Oscillators according to the specified parameters * in the RCC_OscInitTypeDef structure. */ RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE; RCC_OscInitStruct.HSEState = RCC_HSE_ON; RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON; RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE; RCC_OscInitStruc

While using system view tool i have added the required files to the existing project but still some errors are occurred while running2. I have attached image please go through this and let me know is there any ref doc for the Segger System View Tool with STM32 3. The code is without FreeRTOS4. Let me know is there any other settings to be added or ref example5. i Have included the paths in the compiler settings alsoErrors C:/ST/STM32CubeIDE_1.16.0/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.12.3.rel1.win32_1.1.0.202410251130/tools/bin/../lib/gcc/arm-none-eabi/12.3.1/../../../../arm-none-eabi/bin/ld.exe: ./Core/Src/SEGGER_SYSVIEW.o: in function `_TrySendOverflowPacket':D:/Projects/Internal Project/Stm32_Firmware/STMF207ZG_Limit_Switch/Debug/../Core/Src/SEGGER_SYSVIEW.c:664: undefined reference to `SEGGER_RTT_ASM_WriteSkipNoLock'C:/ST/STM32CubeIDE_1

cubeMX version 6.13, generating for CMake.Hi there,I'm configuring an STM32H7S3 nucleo board. I can build, flash, run, and debug code.I am adding a UART for logging and now am getting the titled error when generating:Edit: This problem appears the moment I go to the Memory Management tab! If I reset to previous .ioc state, the code generates happily. If I open the project and simply open the memory management tab, this error appears.In tools>Memory Management it looks like my bootloader and app both live in the 64kB onboard flash I want the bootloader to use the onboard flash, and do execute-in-place for code on the provided NOR flash.I have followed these guides, which seem relatively up-to-date:Getting started with MMT(Memory Management Tool) - stm32mcustm32h7s_workshop/1_external_memory/external_memory.md at main · ST-TOMAS-Workshop/stm32h7s_workshopIn particular, section 6.2.5.1 of the first link shows how application flash will be moved to XSPI.

Hi I'm bit lost and I couldn't find the link to the svd file. Is it somewhere in here https://www.st.com/en/microcontrollers-microprocessors/stm32g051f6.html#tools-software? If I search for svd I get zero result. Which link is it that takes me directly to the svd file?

I have a question regarding GPIO settings for the STM32H743.Does anyone have detailed documentation on the speed of the GPIOx_OSPEEDR register?I would like to know the criteria for using low speed or very high speed. 

Hello, I am trying to implement a BMP 280 with matter. The project is to send the measured temperature back into matter and display on the home app on iPhone. At the end of 1.2.2.5 matter develop and prototype document, it mentioned to check if for each callback in the .h file, the corresponding folder should be added to the CUBE IDE. I have two callbacks in the .h file that I couldn't find a corresponding folder.The first one is: MatterTemperatureMeasurementPluginServerInitCallback();The second one is:MatterBindingPluginServerInitCallback();I am wondering if there's any suggestions on where else I can find the corresponding files, and if there aren't corresponding folders available how would I write my own folders.ThanksBrady

Hi!Any chance this will be supported soon?CubeMX is already updating the auto generated CMake file in STM32 VS Code when adding TouchGFX but this is just for some of the TouchGFX files and is not sufficient, instead there will be build errors.As a related question: is there a way to add custom CMake code in the auto generated CMake file e.g. under "User code begin etc"?Thanks

Hi All, I'm working on implementing the fast transfer mailbox into a project and I've hitt a wall. The work-flow that I want is for my host chip to wake-up and initialize system registers and write some static data I know will never change to area1, then enable the authorization of the mailbox by writing MB_MODE to 0x01 and wait for an RF FIELD ON event (via GPO pulse), after receiving the pulse the host should free the mailbox by writing 0x01 to the MB_CTRL dynamic register and then write some new data to the mailbox.The host successfully writes to the system register and first disables the MB_MODE (system register) so that It can write some static NDEF data to area1 and then re-enables the mailbox at the end of initialization (writing MB_MODE to 0x01). I can confirm by reading with a mobile device and using the ST Tap app that the MB_MODE register is set to 0x01, which as far as I can tell means that I should be able to write from either i2c or an RF command to the MB_CTRL dynam

Hello ST Community,I'm working on an application using the STM32F103C8T6 microcontroller that implements a Sliding Mode Observer (SMO) and Park/Clarke transformations. I'm facing significant performance challenges due to the computational overhead of the floating-point trigonometric functions  atan2f.My system requires a 50us loop execution time, but the SMO alone is taking approximately 20us, largely due to these trigonometric functions. I need to optimize this to meet my timing requirements.Here's a breakdown of my current implementation:MCU: STM32F103C8T6Application: SMO and Park/Clarke transformationsProblem: Excessive execution time of  and atan2f within a 50us loop.Current Performance: SMO takes ~20us.Compiler: stm32cubeideOptimization Flags: O2Clock Frequency: 20khzPlease tell me solution 

Hi everyone,I’m planning to buy an STM32 development board to start learning FreeRTOS. I have experience with bare-metal firmware development, primarily on TI C2000 DSPs and PIC32 MCUs, but I have no prior experience with STM32.My goal is to first learn RTOS concepts and then move on to interfacing with peripherals like I2C, SPI, and CAN.Right now, I’m considering the STM32L4 Discovery Kit IoT Node (B-L475E-IOT01A) because it has onboard sensors and and looks to have a wide FreeRTOS support.Would this be a good choice for a beginner with no prior STM32 experience, or is there another STM32 board that would be better suited for learning FreeRTOS?Any recommendations or insights from experienced STM32 developers would be greatly appreciated!Thanks in advance!

I am using the STM32F723 with custom, self-powered PCB interfaced to a host using USB HS. Everything worked fine with with CubeMX 6.12, but after upgrading to more recent versions, I noticed that the following functions are no longer generated within HAL_PCD_MspInit() (file usbd_conf.c):     __HAL_RCC_USB_OTG_HS_CLK_ENABLE();__HAL_RCC_USB_OTG_HS_ULPI_CLK_ENABLE(); and also the corresponding clock-disabling functions in HAL_PCD_MspDeInit(). If I manually re-insert these calls, everything works again.Anyone knows the reason why these functions are not generated, and if I am missing any USB_HS setting in more recent CubeMX versions that should be taking care of this issue? Thanks!

Hi,Setup:https://github.com/Open-CMSIS-Pack/STM32U5xx_DFP/blob/main/CMSIS/Debug/STM32U535_545_575_585_59x_5Ax.dbgconfCompiler: ARM Keil MDKv5 version 5.41When using Embedded Trace (Sync Trace with 4-bit) and the Debug Description file (.dbgconf Configuration File) from the STM32U5A5 DFP v3.0.0 pack is enabled, the processor enter debug mode, but no trace data is send from processor. The SWD debugger works correctly and it is possible to step through the code, breakpoints, etc.Once in debug mode, a breakpoint is placed on the code, and the GPIOE_MODER register is read back as 0xFFFFFFFF, which indicates that the .dbgconf file is somehow incorrect. The Log Sequence shows that the .dbgconf file is read and executed but the trace signals are not enabled.If the GPIO_MODER register is changed manually (selecting the alternate function mode for PE2, PE3, PE4, PE5 and PE6), the Trace signals are enabled (seen on the oscilloscope) and the Trace data is read correctly in uVision.Do you have an u

Hello Everyone,We are interfacing HDMI Connectors with a microprocessor such as AM625 or AM62P or RK3568 for use in Industrial HMI Controller environment.We would be using HDMI 2.0 or 2.1 data transfer rates.We plan to use a HDMI companion chip such as the HDMI2C4-5F2. We would like to use some filters between the ESD diode and the microprocessor for better immunity from noisy industrial environment.Circuit would typically be Connect ----> ESD Diodes ----> Filters ----> Microprocessor HDMI pins. ( ESD Diodes and Filters shall be typically placed close to the connectors ). For the TDMS pairs, we would use a common mode filter such as ECM4-2450A17M10.However, we wish to know, what kind of filters are required for SCL, SDA, HPD, Enable and VCC pins.Can you please recommend us some part numbers. Regards,Gaurav Joshi

Hello dear friends,this is my first post and I need your help with an issue I have. I designed some devices based on STM32C031C6. I use an I2C command to jump to bootloader and I upload the new firmware via I2C also from a microcomputer using the stm32flash software.The problem comes when I switch to RDP L1. Then, stm32flash can't upload the new firmware. As far I understood, before the upload a mass erase should be done, which is not possible. I can change the RDP level from stm32flash using -k and -j parameters, but this is possible only when I enter bootloader using the jumper configuration. If I enter bootloader from the software via the I2C command, -k and -j parameters result on a NACK from the device.- How can I complete the upload process via I2C, while my devices are secured with RDP L1?- Is the issue software related?- Do I need to switch RDP levels, before the upload? If yes, is a power circle also required? Here is the code I use for the bootloader jump:void JumpToBoot

I enabled CAN in the device tree using STM32CubeMX and followed the instructions in the provided documentation to generate the .dtb file. Afterward, I copied the generated .dtb file to the /boot directory. In the terminal, I ran the following commands: sync reboot After rebooting, I checked the dmesg log and found the following output when filtering for CAN-related messages: dmesg | grep can [ 0.451665] can: controller area network core [ 0.451819] can: raw protocol [ 0.451832] can: broadcast manager protocol [ 0.451847] can: netlink gateway - max_hops=1 However, when I checked the available network interfaces can0 isn't avaliable root@stm32mp1-e1-99-00:~# ls /sys/class/net end0 lo usb0 wlan0 I have attached the dts file for reference

Hi everyone,I’m currently working on an I2C communication setup using the Nucleo-H753ZI DK but the cubeMx document is for the STM32H743BIT (the MCU for my custom board) and aiming to run it in Fast Mode (400 kHz). However, when configuring the I2C clock speed to 400 kHz, the CLK signal becomes unstable, as shown in the attached image.To ensure the setup is functioning correctly, I ran tests with I2C configured at 100 kHz, and the communication works perfectly in that case. I’ve also included an image of the system clock configuration in case there’s something that could be optimized.  Does anyone know what might be causing the instability in the CLK signal, preventing proper communication at 400 kHz? Thanks in advance for your help!
