When will the NUCLEO-C5A3ZG  be available via distributors?The st.com site lists it as available(mass production), but none of the distributors has listed it at all. And the estore lists it as coming soon. Do you have any more concrete dates, will it be available anytime soon?   Best

I'm using STM32F2xx, STM32F4xx, STM32F7xx and STM32L0xx firmware supplied by STM32CubeMX. I need to generate an SBOM for cybersecurity purposes. Can ST provide that or provide documentaiton that can be referenced to generate the SBOM?

Hey all, I've used this tutorial: https://youtu.be/suMytEyQTP4?si=jLtyF5uH1Qd6zpYvto run TouchGFX on several different MCUs/boards such as the black pill or NUCLEO-F446RE. However, I simply cannot get anything to display when I setup TouchGFX on my NUCLEO-WL55JC2. I'm unsure if there is something I'm missing that makes it unfeasible or much more difficult to get it running on the board, but I'm at my wit's end after debugging for hours and finding no issue. The code compiles and programs to the board fine, and I've verified all connections as well as parameters, and I am at a loss as to what to do. If anyone could help I would greatly appreciate it. (Note: I've tried in single core setup to get it to work as well and that did not seem to solve the issue.)

Hello,I am using the ST25R3918 in NFC-F (FeliCa) Card Emulation (CE) mode, controlled by an MCU via RFAL (based on STEVAL-25R3916B_V2.1.0). [Issue Description]The system works correctly under normal conditions: the ST25R3918 receives commands like "Write Without Encryption" or "Read Without Encryption" from a reader and sends back the appropriate responses.However, if the reader is moved away from the ST25R3918 (resulting in RF field loss) during the communication process, the MCU firmware falls into an infinite loop. [Analysis Details]The loop occurs within the do-while block of demoTransceiveBlocking() in card_emulation.c. The call stack is as follows: rfalNfcWorker() -> rfalWorker() -> rfalRunTransceiveWorker() -> rfalTransceiveRx()Inside rfalTransceiveRx(), the state gRFAL.TxRx.state remains stuck at RFAL_TXRX_STATE_RX_WAIT_RXS. The function st25r3916GetInterrupt() is called with the following mask: (ST25R3916_IRQ_MASK_RXS | ST25R3916_IRQ_MASK_NRE | ST25R3916_IRQ

I downloaded the STM32C5 software package from st.com, but I am unable to use IAR. How can I import the CMake project?

Hello,With the new STM32Cube Debug Jlink GDB Server V1.2.0 I'm not anymore able to start the debugging session. If I downgrade to V1.1.0 then it is working again. I get always the error message "No GDB Server running". I tried that with my old launch.json settings and with the new generated and adapted json settings.Do I miss some special settings or has the new extension a bug?Or do i need any dependency? error message: old launch.json new launch.json  Thanks in advance,nobody 

Hello,in our design with STM32H753ZIT6 I've adjusted the C0G load capacitors on the LSE 32.768 kHz crystal so that the real-time clock is now very accurate (less than 1 second error in 24 hours). I've always performed the calibration in VBAT mode at a voltage between 2.3 and 3.2 V.However, now I've noticed that in normal VDD mode with active controller, the real-time clock is running significantly too slow, with an error of 90 seconds in 24 hours. I've ruled out the VBAT supply voltage as the cause. Any ideas what could be causing this large error in normal VDD mode?Thank you!

I was excited to see the Rust support for the Developer Package (seen here and here)However, I am having some issues with the fact that the provided toolchain is version 1.75 rustc and cargo. Mostly the fact that this version cannot use dependencies which use Rust edition 2024.I know I can go through dependencies one by one and downgrade them to earlier versions until there are no edition 2024 dependencies, but this is pretty tedious and doesn't seem like a great solution in the long run.Is there any chance that the MP2 Dev Rust addon could be updated to a more recent version?Or if that isn't possible, is there any advice on other ways to update the provided toolchain or create a custom rust toolchain using the mp2 dev tools?Thanks!

Hi all,I’m exploring whether the S2LP LDC mode can be adapted for a transceiver configuration.From what I understand, ST’s example code provides separate implementations for RX-only and TX-only devices. Using these individual examples, I’ve verified that reliability is good. Additionally, the datasheet also describes the TX and RX sections separately.However, I’m interested in implementing LDC mode in a transceiver setup (where the same device handles both TX and RX). Has anyone implemented this successfully? If so, did it work reliably, and would you be able to share any reference code or guidance?Thanks in advance for your support. @Gyessine @waclawek.jan

Hi ,Recently I got a NUCLEO-C051C8 board and tried to connect it to windows and program it using STm32CubeIDE but it does not show that st-link is connected , ST-link on board blinks RED continuously. Cant install it ( installation goes through , but cant see it in device manager ) using stsw-link009( https://www.st.com/en/development-tools/stsw-link009.html?dl=redirect ) Cant connect using STM32CubeProgrammer. Tried 2 USb cables , various ports of pc but  in vain. Can someone please help ?   

Hi    For some of my project, I need to measure the power consumption of the STM32N6570-DK while running a model on the CPU only versus an NPU + CPU accelerated workload.   I am following the guide  1. How to measure power on the STM32N6 - STMicroelectronics Community 2. STMicroelectronics/x-cube-n6-ai-power-measurement: An AI software application package implementing low-power optimizations and enabling power measurement on STM32N6 DK board.​   Based on these documents, I plan to measure the current via CN2 pins 3 and 4 while powering the board through CN6 (USB-C).   My Question:Does measuring current at this point (CN2 pins 3 & 4) isolate the consumption of the NPU and CPU (VDDCore)? Specifically, I want to know if this measurement will include the power draw from the camera module and LCD display if they are active in the same project.   Any guidance on isolating th

The STM32CubeIDE project output setting is not present in STM32CubeMX2. Is there a way to generate a project that STM32CubeIDE can use? How do I do this? I did try the "CMake" option but wasn't able to get a project to import correctly.

Hello all,I've been using this U5 chip for a couple of years but I am just now trying to update all of the packages to start working on the project again.  I have the U5 firmware at 1.8.0, AZRTOS-H7 at 3.5.0 (I'll explain why I mention that), FileX is 6.4.0 and the CubeIDE is 2.0.0.When I started this project, I was using an H7 chip and that is where the Azure implementation started.  Now things seem integrated and those choices in the software packs selection in CubeMX don't seem to matter...I assume.  The H7 package is the one still loaded to my hard drive.  I've tried creating a new project and setting everything up again but nothing has changed from my original project.  I tried to apply some U5 patch with version 2.2.0 or something like that.  MX took it and made it disappear into the void.  Again, maybe I don't need to care about manual package setup anymore.ThreadOS works great and everything has been working great for me.  I added USBX, F

Hello i use STM32G070CBT6 with PD0 and others pins.PD0 as input pin with no internal pull-up/down with extrenal 10k pullup gives only 0.7V, when i set the pin to output and set state to high there is 3.3V.Where is the problem? 

Dear ST Community,I am currently migrating my Firmware from STM32H723VG to STM32H563VI. I have problem with Internal Temp Sensor. Based on Reference Manual on both MCU reading temperature is the same, but it doesn't work as it should.When on STM32H7 I got about 750 (24 degree Celsius) on reading ADC from TEMP Sens, on STM32H5 I have around 100.I tried both with and without cache (ICache and DCache), with Bare Metal and Zephyr RTOS code. In every configuration it is not working. I tried also on different MCUs, so it shouldn't be part itself.It worked with Nucleo H563ZI, but doesn't with H563VI.What else can I do?

According to Page 1354 of rm0394, setting LDMA_TX bit must occur only when SPE=0.However, from my reading of the function HAL_SPI_Transmit_DMA, this bit may be set or cleared when the DataSize <= 8bit and MemDataAlignment == HALFWORD, even if SPE=1.This looks like a bug.Am I correct?STM32Cube MCU Package for STM32F4 STM32L4, version 1.28.3

Hi,among probably many other registers, the ITM registers like TCR and Stimulus Port Registers described in the ITM programmers model in ARM Cortex-M7 Processor TRM are missing. Which means I either have to adapt the svd file or go to memory view and translate and modify the registers manually. Is this on purpose and or are there plans to fix this? If you have a repository somewhere I can maybe fix that on my own and start PR.Ty in advance

I am setting up my STM32F303RET6 for four differential inputs to be sampled simultaneously. As seen in the screenshot attached. there is no option for differential inputs on CubeMX. Am I missing something here? I have reset whole project to ensure no pins are assigned elsewhere.

Hi I have a USB-C Connector that will be used for Power Delivery Sink  for charging and USB Full Speed Mode(12Mbps) for communicating with onboard STM32F767ZIT6. But only one thing will happen at a time.    As seen in the attached schematics, I have used STUSB4500 as PD Sink controller. I will communicate with it via I2C using STM32. I understand that this STUSB4500 will negotiate 20V(60W which i want for charging) with the source(which in this case is AC-DC Wall adapter) in Power Delivery Mode. But my question is during USB Full Speed Mode Communication with STM32, when that USB-C Receptable is connected to a PC instead of Wall Adapter. As during charging mode, USB_VBus is 20V and in Full Speed mode, it is 5V and my STM32 is Self-Powered and VBus sensing is mandatory. But due to USB VBus varying between 5V and 20V, I cant connect it to for example PA9 VBus sensing pin of STM32 using a voltage divider.  So, i was thinking maybe there is another option to sense

Hello Everyone,I’m still getting up to speed with the STM32N6 series, so apologies if my question seems off, but I’d really appreciate your help!I’m working on implementing object tracking using the STM32N6570-DK board with the MB1854B camera. I'm wondering if it’s possible to deploy OpenCV on this platform to support the tracking logic.If anyone has experience with this or knows of any courses, guides, or resources that could help me deploy OpenCV (or similar tracking frameworks) to the board, I’d be incredibly grateful.Also, if you have relevant experience and are open to offering support or consultancy, I’m more than happy to discuss compensation. Please feel free to reach out!Thanks in advance for your time and help!
