Hello, I am trying to load a kernel driver (.ko file) for a MIPI camera I would like to use with the STM32MP257F-DK. It's for the imx664, and no driver is present already. I have the source for the driver, and was able to compile it into a .ko file, cross-compiled with the exact same OS as is present on the board and with the SDK set up as required. The vermagic line matches exactly: vermagic: 6.6.78 SMP preempt mod_unload aarch64However, every time I try and load the driver with insmod, with or without -f, I get the error: insmod: ERROR: could not insert module imx664.ko: Invalid module formatI am struggling to find where the incompatibility could be, since I have re-tried it a few times and been careful to set it up as ST's documentation says and also to match what is expected by the board. Is there something I am missing with this?

We develop a measuring device which should be capable of SIL 2. It would be possible to fall back to SIL 1 only. STM32F4 MCU is used with STL-Safety-Library.Has anybody qualified the gcc for that? Or did you replace the compiler by already qualified products from Keil, IAR?If you have qualified the gcc, have you done it yourself or used commercial tools?

I am porting the ST67W611M1 WiFi/BLE driver (X-CUBE-ST67W61 v1.2.0) from a NUCLEO-U575ZI-Q to a custom PCB with STM32F767VIT6. The Nucleo version works perfectly.

Apologies in advance, this is a long one.We are developing a camera application on an STM32H747. We have 32GB of SDRAM configured through FMC.We have a NanEyeC camera from which we are continuously acquiring data in packed bayered format via SPI, into one of three SDRAM framebuffers [A1,A2,A3] (a three-buffer system so that one is reading, one is pending, and one is writing).On our main loop we check to see if one of the raw camera data [A1,A2,A3] has available data and then (1) unpack and debayer it into a 320x320 RGB888 SDRAM framebuffer [B] (we want this intermediate point from which the user can save images), then runs a scaling operation to transfer it into a 460x460 (our display size) RGB888 SDRAM framebuffer [C],After these for loops we start a DMA2D transfer which combines [C] with overlay graphics in 460x460 ARGB4444 SDRAM framebuffer [D], and outputs the result into 460x460 RGB888 SDRAM framebuffer [E], and the DMA2D end-of-transfe

Hie, according to the documentation of the board, USART1 can be used with db9 port by setting up JP7 and JP8 to 1 and 2 ( which I did). The second thing is to connect usart_tx and usart_rx to PB14 and PB15.The problem is that nothing is showing up on the pc with DB3 port. I've check the tx port with an oscilloscope and I'm getting signal on data sending but only 1.1 V (in AC). I don't know if it's part of the issue but I hope someone has the solutionThanks

I am working with an STM32F769NI and planning to implement my own Ethernet driver without using the HAL. While studying the DMA descriptor system, I found that the hardware supports both ring structure and chain structure descriptors. However, I am having trouble understanding the exact behavior of the ring structure. For example, suppose I have three TX descriptors: DESC0, DESC1, and DESC2. After the DMA finishes transmitting DESC0, how does it advance to DESC1? Since the descriptor size is fixed, does the hardware simply move to the next descriptor by doing something like: current_descriptor_address + descriptor_size? If that is the case, then I don’t clearly understand what the pr

Hello ST team,We are working with the STM32WL5MOC6HTR module for a LoRaWAN end-device design.We understand that the STM32WL5MOC6HS variant includes an STSAFE-A110 secure element, but our custom module (MOC6HTR) does not include STSAFE.Our question is about securely storing LoRaWAN keys such as:AppKeyNwkSKeyAppSKey We are exploring options like:Using the LoRaWAN Crypto middleware (Middlewares/Third_Party/LoRaWAN/Crypto) with the internal AES peripheral,Leveraging SBSFU (Secure Boot and Secure Firmware Update) for Flash protection (RDP/PCROP),Or possibly using KMS-MW (Key Management Services Middleware). Could you please confirm:What is the recommended approach for securely storing LoRaWAN keys in the STM32WL5MOC6HTR, where STSAFE is not present?Can KMS-MW or SBSFU be used on this device to provide a secure key storage area or API abstraction similar to a secure element?

I am using MEMS Studio to evaluate FSM and MLC on the STEVAL-MKI109D + STEVAL-MKI238A . I noticed few strange things. I am attaching my FSM gui config and reg config (config.zip)1. When I open the FSM tab and load the state machine files and device configuration fileone thing I notice right away that its not loading the Long Counter Max value correctly.In my saved FSM configuration I have set it to 0x14 but when I load the configuration it still showing up at 0001

I'm using VSCode and J-Link for programming/flashing my STM23 MCUs.Unfortunately using the default setup from SEGGER (https://kb.segger.com/J-Link_Visual_Studio_Code#Support),J-Link only erases areas/pages needed.I found no information about modifying the process of flashing.Is there a way to modify the setup within VSCode in a way, to do a full chip erase when flasing by default?Many thanks!

Hello everyone, I am using the NUCLEO-H755ZI-Q board for a project. I have noticed that the HRTIMs thatare not multiplexed with some USB pins (like the HRTIM_D1 with the D+ for programming the IC via usb)work normally, while if they do, I can't output any PWM pulse. Is this actually a thing and to overcome itI have to remove some of the Zero Ohm resistors behind the nucleo board or design a custom pcb for my needsor am I messing something up? In my situation specifically, i can output from all HRTIM channels except the D1and D2, both of which map to a pin with USB. Thanks in advance! 

 Split from original question Can you check your documentation ?  According to RM086 - Reference Manual for STM32N657, all PH GPIOs can be set as input/output (contradicting your previous post). Default State: When a crystal is used for the HSE (PH0/PH1), PH1 is dedicated to the oscillator output and cannot be used as a general-purpose I/O (GPIO).Bypass Mode: When you configure the RCC (Reset and Clock Control) to "HSE Bypass," an external clock signal is fed directly into PH0 (OSC_IN), freeing up the PH1 pin to act as a standard GPIO.

Looking to add a 4 mic pdm array setup to livetune environment. Had questions on how deep into the environment we need to go for the changes. Is it just a matter of changing the # of channels for the sysIn, # of slots and active slots on the pdm interface? or do we need to drive deep as address the audio buffer as well. At one point I thought I read the audio buffer was allocated dynamically. We are just looking for a little guidance before we start changing things as there might be a simple way to achieve our goal vs us guessing and creating issues.

I am working on a project that uses the ST67W611 for cloud connectivity, but I am experiencing some issues when trying to connect to AWS IoT Core.Note: The NCP is already flashed with the T01 binary. The AWS endpoint is correct — for the sake of this question, let’s assume it is:xxxxxx-something.amazonaws.com. What Works Broker: test.mosquitto.org I am able to publish data to the broker and receive data from it when using test.mosquitto.org. However, I am now trying to get it working so that our custom device can connect to AWS IoT Core.

I work in a workspace but I use vim with clangd for editing my code. I am wondering if it is possible to create a compile_commands.json file and if so how. If the IDE uses cmake under the hood then it should be rather straightforward but I cannot understand how to proceed. see e.g. this:https://cmake.org/cmake/help/latest/variable/CMAKE_EXPORT_COMPILE_COMMANDS.html 

I've successfully set up a docker container building my project using the headless script. I've also successfully generated a Windows version of the compile_commands.json using the setting inside the properties menu. But I need a version of this that's from the linux build, because I want to lint inside the docker container for continuous integration. I've looked at what gets changed inside the .settings folder when that setting is changed in the normal non headless IDE ("generateCDB=true"), and I've tried simply building the code with that folder and the files in it in the same place in linux, but compile_commands.json is not generated.

I am looking for a way to use a different editor for a STM32CubeIDE project. For the editor to show correct errors and provide code-completion, I would need a compile_commands.json file, which the clangd language server can use.I found this post which describes how to generate this file using an external program called compiledb. But I also found a setting in STM32CubeIDE under Project -> Properties -> C/C++ Build -> JSON Compilation Database Generator, which can be enabled to have STM32CubeIDE generate a compile_commands.json file when building aut

Hello,I was checking if it is possible to test my M33 NS code I generated using CubeMX would work in Developer Mode. However, the information found on internet suggest it being difficult as it requires the clock to be configured by M33 and also needs RIF accesses making it difficult. Without proper documentation on use case and how to use developer mode, it becomes challenging to work on a project within a stipulated time. So please, I would request for the help and Information to test and debug the code in Developer mode. Thanks for the support.With regardsAmit

Hello! Has anyone tried to deploy multiple neural networks on a stm32n6 at once? I'm developing an application which requires 5 NN. I created 5 .c libraries to deploy each NN on the NPU, I assume is because of the APIs that they overlap. So I'm curious if anyone has tried this and how it was solved. My last  option is to create a bigger models that contains all 5 on onnx, then deploy it, idk if someone knows if this could work to. 

Hello,I don't have so much experience with the boards of STM32 and I'm struggling a bit (actually a lot) with a quite simple task.I want to run a blinking test with the board STM32MP257F-EV1.I installed the STM32CubeMX, STM32CubeIDE and STM32CubeProgrammer.First I generated the code with CubeMX and added the code for blinking in the CubeIDE. Then I clicked on Run -> Debug and there was this error:Error message from debugger back end:Remote communication error. Target disconnected: (undocumented errno 10061).I changed the BOOT switches to 0 1 0 0, and then did Run -> Debug again. This time there was this error:Open On-Chip Debugger 0.12.0+dev-00608-gd8ed48fef (2025-02-06-11:17) [https://github.com/STMicroelec

Hi everyone, I am trying to read pulses of a rotary incremental encoder npn  on the screen connected to a Jetson sbc, through SPI connection with a STM32 NUCLEO-G474RE. On CubeMx i already modified pins, generated code and flashed on stm32. Once i run the python code on Jetson, no pulses are seen on the monitor.  Do you have any suggestion? Thank you in advance.

Hello ST Community,I am using the NanoEdge AI Studio to generate an anomaly detection library for an STM32L4 device (fixed installation, vibration monitoring). The library works fine, but I need to persist the knowledge learned during runtime so that after a power cycle or reboot, the device does not have to learn again from scratch.I followed the official documentation and community advice (including the solution marked as accepted in [this thread](https://community.st.com/t5/edge-ai/is-there-any-way-to-save-or-export-knowledge-which/td-p/123456)):- Added the `.neai` section in my linker script with `KEEP(*(.neai))`- Declared `extern char _sneai_knowledge[];` and `extern char _eneai_knowledge[];`- Computed `NEAI_KNOWLEDGE_SIZE = (uint32_t)_eneai_knowledge - (uint32_t)_sneai_knowledge;`- Implemented functions to save t

Hey guys!I am currently working with Secure Boot using ARM TrustZones, Secure and Non-Secure!I have ***ed up my code majorly hehe, and I cant just Ctrl + Z everything since I have edited in a lot of files and generated code from CubeMX (UART, HAL, HASH etc), is there a smooth way to go back to an older version of the entire folder, for example an older version of NonSecure and Secure etc.Thanks in advance!
