Even I am using the latest CubeProgrammer v2.21.0, it indicates an update available but when I check it, there is no update and the updater log does not update, it cannot update its last update date as well.I know not so important but quite annoying problem, i`d like to mention, 

Dear ST team,I need some tips!!!I am using STM32H745 for my project. In the project, the M7 core is dedicated to control and measure the power circuit values and M4 core is responsible for communications (few UARTs) and LCD. I configured the MCU with STM32CubeMX and use Keil uvision fore code composing. After generating code, I noticed that there are two separated codes were generated for each CPU.How can I bridge between two CPUs to share data? I want to send measured data by M7 via UARTs controlled by M4?I will appreciate if you give me some applicable suggestions.

Hi,We are designing a compact, battery-powered system that requires a regulated high-voltage DC output with the following specifications:• Input: 5V• Output: Adjustable 400V to 1000V• Load current: 1µA to 200µA• Very low ripple and noise• High efficiency and small form factorThe supply will be used as a bias source for sensitive detectors (e.g., APD/PMT-type devices), so output stability and low noise are critical. The output must remain stable across the specified load range.I am currently considering a closed-loop flyback topology with post-filtering, but I am open to alternative architectures.Could you please recommend:• Suitable controller ICs from your portfolio?• Relevant reference designs or evaluation boards?• Design techniques for minimizing ripple and noise at these voltage levels?Any guidance or application notes would be greatly appreciated.Thank you.  

I have build a Fully pin compatible STM32H750B-DK board with USB Device only setup along with Touchgfx and Freertos , Touchgfx is displaying everything correctly but the USB Isn't responding , I have setup the USB OTG FS in Device Mode as shown in the attached Images.PC is not detecting anything

Hello everyone,I’m working on a project with an STM32H750B-DK board using TouchGFX and LWIP (Ethernet). After configuring LWIP in CubeMX and generating the code, I encountered a compilation error that took me a while to understand. I’d like to share the problem to help anyone who might run into the same issue.The ErrorIn file included from ../Application/User/gui/NetworkTask.cpp:13: ../../TouchGFX/gui/include/gui/model/ModelListener.hpp:13:23: error: macro "bind" requires 3 arguments, but only 1 given 13 | void bind(Model* m) | ^ In file included from ../Application/User/gui/NetworkTask.cpp:11: ../../Middlewares/Third_Party/LwIP/src/include/lwip/sockets.h:616: note: macro "bind" defined here 616 | #define bind(s,name,namelen) lwip_bind(s,name,namelen) | Similar errors appeared for Model.hpp.

Hi everyone,I am experiencing a strange discrepancy in the behavior of HAL_UARTEx_ReceiveToIdle_DMA between LPUART2 and LPUART3 on an STM32U083RCT6.Environment:MCU: STM32U083RCT6IDE: STM32CubeIDE v1.17.0Library: STM32CubeU0 Firmware Package V1.3.0 (Released 04-June-2025)The Issue: I am using HAL_UARTEx_ReceiveToIdle_DMA to handle asynchronous reception of variable-length packets.LPUART2: Works perfectly. When an IDLE line is detected, the DMA transfer stops as expected, and HAL_UARTEx_RxEventCallback is triggered.LPUART3: When an IDLE line is detected, the interrupt is generated and HAL_UARTEx_RxEventCallback is triggered correctly. I am able to handle and process the variable-length packets without any issues. However, the DMA transfer itself does not stop (it remains in an active state), unlike the behavior observed on LPUART2.Configuration: Both instances are configured in STM32CubeMX as follows:Baud Rate: * LPUART2: 230400 bpsLPUART3: 115200 bpsDMA: DMA1 [Channel configuration]Mode

Started project (using STM32CubeMX) with STM32C011J4M6 (SO8 package, 16K flash).Using STM32CubeIDEVersion: 1.19.0Build: 25607_20250703_0907 (UTC)Application now requires >16K (flash (code+flash data space) so replaced MCU part with STM32C011J6M6 (SO8 package, 32K flash).After adding content to project source code (a font file, taking the expected total flash space over 16384 bytes) build does not complete.I believe the root cause is that I've not told STM32CubeIDE of change to the larger-flash version of the chip (same family, just larger flash).What file(s) need to be edited to enable the larger flash size (or do I need to revert to STM32CubeMX and then splice the now under-development project source code into the new project? C:/ST/STM32CubeIDE_1.19.0/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.13.3.rel1.win32_1.0.0.202411081344/tools/bin/../lib/gcc/arm-none-eabi/13.3.1/../../../../arm-none-eabi/bin/ld.exe: (MY PROJECT NAME).elf section `.d

Hi,I want clarification on STM32 option byte programming.When we write new values to FLASH_OPTR and other option registers:Where are these FLASH option registers physically located?Are they inside the FLASH peripheral (0x4002xxxx region) and not in the option byte Flash area (0x1FFF8000)?When OPTSTRT is set, does the CPU erase/program the option byte pages, or does the FLASH controller hardware automatically erase the option byte Flash area and program it using the values in the FLASH option registers?I want to clearly understand the internal flow between:Option byte Flash memoryFLASH option registersFLASH controller hardwareThank you.

I am trying to bring up the GFX01M2 on a WB55RG board. Following any of the Custom, FlashLoader, or HelloWorld applications (from the X-CUBE-DISPLAY_3-0-0 download) using STM32CubeIDE merely results in a blank LCD. I feel I'm missing something simple, but just can't find it. In each case I have compiled and loaded the files as per the ReadMe instructions. Any pointers appreciated...

Hello,I am working with the STM32L476 and would like some clarification regarding the One-Time Programmable (OTP) area.From the reference manual, I understand that STM32L4 devices provide 1 KB of user OTP memory (128 double words). I would like to better understand the following:What exactly is stored in the OTP area? Is the OTP region purely user-programmable, or does ST also store factory calibration or security-related data in this region? Is OTP used internally by the MCU for enforcing Flash security mechanisms such as RDP, WRP, or PCROP, or is it strictly for user data? How is OTP protected ? I am trying to understand the architectural role of OTP in relation to Flash protection and secure boot mechanisms.Thank you.

I have the Nucleo-144 board N657X0Q.It appears to work (i believe there is demo code pre-installed - it is flashing a red led and the frequency changes when I press the user button).  However, I cannot get the Cube IDE or Cube Programmer to work with it.  I am just trying to read memory using the cube programmer as a test.  It connects, gets the information about the board, uploads the loader firmware, and then when it tries to read it gets an error and disconnects.The log file is attached.  I have tried using two different machines as hosts, and tried 2 different usb cables (both are suggestions from several posts I found).  I have tried reducing the speed, and using the "under reset" and "hotplug" modes to no avail.  I have selected the correct external loader before doing the check.  I am using a separate power supply on the user USB to rule out any problems with enough power from the host machines on the USB port.I don't know what to try

Hi,we are trying to get SDMMC1 running on our evaluation boards (STM32H757-EVAL) but without any success so far.To further investigate the issue we started a new project from scratch, using CubeMX with sdmmc1 enabled. It doesn't work neither.btw: board and SD interface are OK. i.e.the demo that came with the board is reading video files from SD card successfully.Please, can someone provide a ruuning setup for Cube-MX (STM32H7 firmware 11 or 12) with the specific settings for Clock Configuration and SDMMC1.We are using CubeMX 1.15, STM32H7 firmware package V. 12.1.The error happens during SD PowerOn(), i.e. there is no response from CMD8, CMD55...Thanks for your helpTom  

Heyho,when enabling the INSTRUCTION cache in STM32H7(33), what must be taken care of?Any cache handling required? Any MPU settings required?As far as I understood that's only required for DATA cache?

In the STM32WB09's Reference Manual, RM0505 Rev 3, Table 8: PA10 and PA11 have SWD modes for their AF4.However, in the STM32WB09 datasheet, DS14210 Rev 6, Table 6 and Table 7: PA10 and PA11 have no AF4. Which one is correct?

Hi everyone,I am experiencing an issue with STM32CubeMX version 6.16.0 while working on an STM32U375xx based project.When I set the Toolchain/IDE to CMake, the code generation process completes successfully, but the linker script (STM32U375xx_FLASH.ld) is missing from the project structure. I have checked both the root directory and the cmake/ folder, but the file is nowhere to be found.Interestingly, if I switch the Toolchain to STM32CubeIDE, the .ld file is generated as expected. This suggests a potential issue or a change in behavior specifically for the CMake generator with the new U3 series in this version of CubeMX.Environment details:MCU: STM32U375xxSTM32CubeMX Version: 6.16.0Toolchain: CMakeHas anyone else encountered this problem? Is there a specific configuration I should check in the Project Manager to ensure the linker script is included in the CMake output?Thanks for your support!Best regards,Gianni

Could you explain the necessary configurations in STM32CubeMX and how to write the code in STM32CubeIDE to interface these components?My Tool version infoCube IDE 2.0.0Cube MX 6.16.0Best RegardsRanjith

This fault is still happening since Oct 2024. However I found a workaround documented here -->https://stackoverflow.com/questions/78850472/stm32cubeprogrammer-flash-loader-cannot-be-loadedIn case the link has died, you need to do the following...Connect STM32CubeProgrammer to your STM32 device and note the "Device ID" listed in the "Target Information" window bottom right of the CubeProgrammer app, e.g. for an STM32F103 this will be 0x410.cd into your "STM32CubeProgrammer/bin/FlashLoader" folder.duplicate the file that matches your device ID (e.g. for an STM32F103 the file would be 0x410.stldr)and then rename the duplicated file "0x".Then restart STM32CubeProgrammer and it will now work properly.  

Hello,I have the issue that the FlashLoader is detected but not set correctly. The error message is:flash loader cannot be loaded. FlashLoaderPath = CubeProgrammer/bin/FlashLoader/0xAs a workaround I can create a copy of the correct FlashLoader and name it 0x, but I think this should work automatically. I am running on Linux and the issue exists for several versions of CubeProgrammer and on multiple Linux distros for me. My current version 2.21.0.The issue is really annoying if you switch boards and forget to copy-rename the correct FlashLoader.
