I purchased the EVALSTGAP2HS board for evaluating STGAP2HS gate drives. I'm disappointed in the available documentation for this board, but finally I deduced that the only correct way toconnect devices is as shown in the figure I'm a bit puzzled by the location for the designators, and what appears to represent the courtyard for the MOSFETs... For quick and dirty evaluation, is this how you would place the leads ?  Thanks :)

I'd like to move from mickledore to the current ST offering on scarthgap.  We are using the STM32MP157D.We require a web browser, and WebKit worked well for us on mickledore using QT5.Since QT has been spun out to a plug-in and it is unclear how well-supported it is (ST's documentation seems lagging), I decided to go with Weston/Wayland and use a simple GTK/GDK app.Westion is working - the GPU `/usr/local/demo/bin/weston-st-egl-cube-tex` runs nicely.  Simple apps using GDK are also working.Sadly, though, the app embedding a WebKit view has a hard-to-describe random flickering issue.  It renders the page but then randomly overlays a white screen that occasionally flashes on and off. Anyone able to offer some experience:- Has anyone got a lightweight browser working on the STM32MP1 using the GPU and the recent ST scarthgap releases?- Or got QT6 working on STM32MP1.  Did you use the ST's "QT plug-in"?- Any advice for configuring webkitgtk3 (found in meta-oe)?&nbsp

Hi all,this issue is related to: https://community.st.com/t5/stm32cubemx-mcus/cmake-project-generation-with-cubemx-cubeai-fail/m-p/770680/highlight/true#M31054. , where it was solved by updating from STM32CubeMX V6.12.0 to STM32CubeMX V6.13.0. However, I have STM32CubeMX V6.16.1, so the error might have reappeared.Background: I try two write code for an STM32N6 and use a CMake project for this. For the setup, I used the following tutorial: https://community.st.com/t5/stm32-mcus/how-to-debug-the-stm32n6-using-vs-code/ta-p/833499 and I can compile + flash the code and get a blinking LED, so the CMake project itself is working correctly.However, when I export a neural network to the Application using CubeAI, CubeMX generates wrong relative paths in Appli/mx-generate.cmake. More specifically, all paths related to CubeAI have one "../" more than needed. Example: ----------------set(ST_Src${CMAKE_CURRENT_SOURCE_DIR}/../../Middlewares/ST/AI/Npu/ll_aton/ll_at

Using various STM32 MCUs, I have a intermittent bug occuring in malloc() where it returns a nonsensical address for no apparent reason.After hours of digging I managed to find some some source code for newlib from https://sourceware.org/newlib/for newlib-4.5.0.20241231 which at least let me step into the internals of malloc to try and find the problem but as thats a slightly different release to the one used by STM32CubeIDE the bug mutated to something less frequent.My main problem currently is trying to find an issue list \ bug tracker for newlib, so I can see what issues others are having with it. Usually I end up on a site like github and their issue tracker, which is great, but for newlib there seems to be a myraid of git repos and sourceware.org with primitive mailing lists, some being long in the tooth.It would also have helped if ST Micro indicated exactly which version of newlib they embed into STM32CubeIDE (and\or provided the source code for it too).  &nbs

I have a project that uses different MCUs. 99.99% of the code is common for all, so I have different .project, .cproject and .ioc files for each, and use CubeMx to handle the hardware initialization.Currently, it requires manual building: Close the project, copy and replace the files, open the project, trigger code generation and compile.Now I'm trying to automate that.Replacing these files in a script and calling the compiler (headless build) is the easy part.This compiles correctly when the code was already generated with CubeMX.org.eclipse.cdt.managedbuilder.core.headlessbuild -import C:\projects\my_project -build my_project/ReleaseHowever, I was unable to automate CubeMX generationI tried using CubeMx from CubeIDE, and also standalone version, with the same results:C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeMX\STM32CubeMX.exe C:\ST\STM32CubeIDE_1.7.0\STM32CubeIDE\plugins\com.st.stm32cube.common.mx_6.3.0.202107141111\STM32CubeMX.jarIf I only run this, it load the config

Since ~2 hours I get thousands of mails from notification@communitymailer.st.com mainly with STM8 stuff from the last years.What's going wrong here? Is it only me?

I would like to use MDMA on Cortex M4 to move data from DDR to SRAM in order to overcome the SRAM size limitation, especially in Ecosystem 6 secure context when a SYSRAM bank is dedicated to OPTEE.My idea is to move to DDR some data structures used by code running on Cortex M4 and, when needed by the code, to use MDMA to move such data from DDR to SRAM and then to unload such same structures from SRAM to DDR.I found that MDMA is the preferred way to move data DDR <-> SRAM, but it isn't supported by STM32 MCUs Embedded Software.https://wiki.stmicroelectronics.cn/stm32mpu/wiki/MDMA_internal_peripheral#Software_frameworks_and_driversDo you have any suggestion about how to proceed ?

Hello everyone, this is my first time using an ST microcontroller. Specifically, I am using the MB1389E (NUCLEO-WL55JC1) development board. It has been a bit confusing because most of the tutorials have an old version of STM32CubeIDE where everything was there, but now it seems that many tools must be downloaded separately, such as STM32CubeMX. After solving that, I've managed to get it to perform the most basic functions, such as turning LEDs on and off. However, due to project requirements, I now have to take a big leap and make a connection through the Sigfox network. To do this, I've tried using the Sigfox_AT_Slave example from the STM32CubeWL package, which indicates that by entering “AT” in the terminal will print the ID and PAC of the card to register it in Sigfox, but I have not been successful in that part since even when the code loads without errors, it does not show me anything in the terminal, which in this case I use PuTTY, and I have configured the frequencies of 9600 an

With Apple planning to deprecate Rosetta 2 after macOS Tahoe, I’d like to ask about the future of ST tools on macOS. As far as I understand, some of the current tools still rely on Rosetta, so this could become a problem for Apple Silicon users going forward.Are there any plans to provide native ARM versions of the ST tools? And for long-term use, would you recommend staying with the current `stlink-server`, or is it safer to start migrating to OpenOCD to avoid being blocked once Rosetta support is gone?Thanks!

Hello STM Support Team, I am currently using the ADC1283 to acquire analog data with the PIC32MZ2048EFH100 microcontroller via SPI. I have verified that the MCU’s SPI module works correctly when tested independently. However, when interfacing with the ADC1283, the device is not returning valid conversion data and consistently responds with 0xFF. At this point, I am unsure whether the issue is hardware-related or software-related. I am sharing the following for your review: Firmware source files (.C and .H) (I referred one of your example firmware for ADC1283 from any online portal and created logic).  SPI configuration details Schematic diagram logic analyzer waveform. Could you please review them and help identify the root cause of the issue? Our project is currently in the testing phase, so resolving this issue is quite urgent. Your prompt support would be greatly appreciated. Thank you in advance. Best regards,Tushar

Hi I am using the STM32N6570-DK board for AI application development and want to flash the code from the 'https://github.com/STMicroelectronics/STM32N6-GettingStarted-ImageClassification' repository. However, when I flash the .elf file from the debug folder, I get an invalid output. Do I need to flash the FSBL and model hex separately? Is there a specific flashing sequence I should follow? Currently, both BOOT0 and BOOT1 are set to 0, and I suspect the AI model is missing from the flash memory.Best RegardsRam

Basically continuation of https://community.st.com/t5/stm32cubeprogrammer-mcus/stm32cubeprogrammer-upload-fail-after-update-to-2-20/td-p/825113 - after fixing the hex to correctly span both the banks, upload error (using ST-Link) still persists. Firmware can be uploaded using USB bootloader, just the ST-LINK upload fails. It seems that this is a bug of the STM32CubeProgrammer.STM32CubeProgrammer v2.20.0.I attach the firmware hex. I also attach log from the programmer.@PKola.1 @STOne-32 @Maryem  

Hello,I've got a question about pairing and bonding for BLE with iOS devices for ST67W61.I've checked available functions and AT commands, I don't see any mean to encrypt the characteristic. As the iOS BLE stack requires it to pair and bond - am I missing something or it's not yet implemented?Best regards

Dear ST Community, I hope you are doing well. I am currently working with the STM32U5 development board and would like to integrate an SD card module using SPI communication. However, while configuring my project in STM32CubeMX / CubeIDE, I was unable to find the FATFS middleware option under the middleware section. My goal is to use FATFS with an SD card operating in SPI mode. Could you please guide me on how to enable or integrate FATFS for SPI-based SD card communication on the STM32U5 series? If manual integration is required, I would appreciate any official documentation, example projects, or recommended procedures.

I bought an ST-link V2 from amazon, this error occured, fearing it may be counterfeit, I then bought another St-link v2 from STM website itself so there is no way it is fake, but the same error still occured. I am on Mac M3 using Cubeprogrammer. There is utterly no documentation on this error. What do i do.
