STM32 MCUs

I am experiencing a problem with RTOS Proxy in STM32CubeIDE 2.0.0/2.1.0 when debugging a ThreadX application on STM32H753 using a SEGGER J-Link.The same setup works correctly with STM32CubeIDE 1.19.0, but after upgrading to 2.0.0/2.1.0 the debugger aborts during the flash download when RTOS Proxy is enabled. If I use J-Link Kernel Awareness instead RTOS Proxy everything works fine.ConfigurationMCU: STM32H753BIRTOS: ThreadXSTM32CubeIDE: 2.0.0RTOS Proxy: ThreadX / Cortex-M7Debug probe: SEGGER J-Link Ultra+J-Link GDB Server: V8.80Interface: SWDDebug configuration:RTOS Awareness: EnabledRTOS Kernel Awareness: RTOS ProxyRTOS: ThreadX (Cortex-M7)ProblemWhen starting a debug session, the debugger stops at the point where the firmware should be downloaded.The following error appears:Remote communication error.

Hello, I am using the STM32H503 MCU. When I configure the pins as follows:PB2 → OUTPUTPA8 → TIM1_CH1PB7 → I2C1_SDAIn the RCC section, I get red warnings for Master Clock Output1 (MCO), LSCO clock output, and SAI1 External clock. I cannot disable these clock settings. Is there a way to do this in CubeMX? How can I resolve this conflict in CubeMX?

Hello together,I search for a solution to put calibration data in a NS area.Background Information:we are using STM35H573 with STM secure manager.we use an ethernet Rest API to update Application including request install and so onNow I want to use the same Rest API to update configuration data. The BIN file shall be signed like a normal application. The behavior should be more or less the same: Restart µC, SM checks validity; app will be started,...I have read um3254 but I do not understand the section with large profile.I have read something about ITS, but I think this is not the solution I need. The calibration data must not be stored in the trusted area. They shall only validated bei the SM during update or startup. Thanks for joining this topic. Br Sebastian 

Should each vdd pin of the stm32f407zgt6 read continuity like the blue pill on multimeter, are they internally connected within the chip or separated? Similary for all the vss pins are they also all connected vss inside stm32f407zgt6 Thanks

Hello everyone, I am Li Weiwei (李炜炜) from  a company based in Shenzhen, China, specializing in integrated circuit testing equipment and related R&D. We are currently working on a small-scale R&D / prototyping project that requires the STM32F103TBU6 (VFQFPN36 package) in bare die or wafer form (Known Good Die / KGD preferred), rather than packaged chips. Has anyone here successfully sourced STM32F103 series (or similar STM32F1xx) as bare die / wafer through ST directly, authorized distributors (e.g., Avnet, WT Microelectronics, WPG Holdings, Excelpoint, etc.), or other specialized bare die suppliers? Key details I'm looking for: Is the bare die / wafer option officially available for STM32F103TBU6? (I couldn't find it listed on the ST eStore, public datasheets, or standard channels.) Typical MOQ (minimum order quantity) — e.g., full wafer, partial wafer, or small engineering samples (our target: equivalent to 1–5 wafers or a small number of dies for initial prototyping)? R

I have question on STM32WBA65RI uC we are using it for our products TEK923/926. It seem to me that BLE stack doesn’t allow to use Free Running Binary mode and Calendar Mode.There is option of MIX Mode in CubeMX but doesn’t seem working.

Hi,Having just updated to STM32CubeIDE 2.1.1, I've created an STM32CubeIDE Empty Project (the only apparent relevant option) targeting the STM32F072 Discovery Kit as I want to experiment with the touch sensing capabilities, however when the project is created I don't see an IOC file. Has the workflow reverted to using STM32CubeMX to create the IOC file etc. please?Kind regards,Al

Why, oh why have you separated IDE and MX such that .ioc files can no longer be opened in IDE?I cannot imagine any benefits and it makes the IDE significantly worse, such that I've felt compelled to revert to version 1.19.0 ( go to Help -> About STM32CubeIDE -> Installation Details -> Installation History -> select version -> Revert)I couldn't find any other means of feeding back my strong dislike of this change other than a post like this. I hope version 2.1.0 comes out soon and re-integrates MX and IDE!

I tried doing an OBD2 request via Car's OBD2 port.I am able to see the CAN BUS traffic using an oscilloscope , just my request frames are rejected by car. I am using STM32h735G-DK development board to send OBD2 requests. It consists of an inbuilt FDCAN transceiver. Settings are fine (removed termination resistor as car already has two), baudrate is 500kbps  with 87.5% sample point. I am using the following code to send OBD2 request frames:I am able to receive CAN frames and able to log CAN frame frames it is just that frames sent are rejected. What am i doing wrong here?FDCAN Code excerpt: /* ============ 500 kbit/s Bit Timing Derivation ============ * * Step 1: FDCAN Kernel Clock * fCAN = 80 MHz (from Clock Configuration) * * Step 2: Prescaler * Prescaler = 10 * * Step 3: Time Quantum (tq) * tq = Prescaler / fCAN * tq = 10 / 80,000,000 Hz = 0.125 µs = 125 ns * * Step 4: Bit Segments (in TQ) * Sync Segment = 1 TQ (fixed, always 1) * Time Segment 1 = 12 TQ (Prop_

My BLE project on stm32wba65 makes use of "UTIL_TIMER_Create" to set a callback. This works ok when the RTC is configured just as free running binary. If I set the rtc mode to mixed binary & bcd, the callback never gets fired. I'm using an LSE to drive the rtc. Why is this? I'm trying to base a project off the BLE_Heartrate example. I need the calendar time & date so I can timestamp data. I synch the time over the BLE from a PC. I suppose I could just use the ms ticks since boot, but how does this survive a reset (but not power outage)? Is the binary counter derived from the rtc sufficiently large enough to hold a date for a year or more? Any examples using binary RTC and external time synch would be most welcome.

Hi, I am currently working on a project where I want to adjust the duty cycle and trigger an ADC measurement on every counter rollover. I managed to get the PWM running in center-aligned mode, but I’m having trouble triggering the counter rollover at the correct moment. To verify whether the trigger is correct, I routed the output compare signal to an external pin and observed it on an oscilloscope. The basic idea is to run an additional counter alongside the PWM. This counter should count up to ARR and then generate a trigger that starts the ADC conversion. Becuase in the center aligned mode two update event occurs both on CNT=0 and CNT=ARR. On the oscilloscope, it looks like the trigger—presumably when CNT = 0 (at least that’s my assumption)—produces an edge. Im using NUCLEO-G491RE. What could I be missing here? What might be causing this behavior?   Yellow (PWM TIM8 Channel3), Blue (PWM TIM8 Channel1), Orange (Capture Compare TIM8 Channel 4) Thank you in advance!

There is something strange happening with STM32N657x0HxQ MCU when HAL tick timer is not using SysTick, but a timer like TIM6, and TIMPRE is changed to 4 or 8 while timer is active. Observed it on DK and custom board.I created isolated test code with CubeMX v6.17.0 for STM32N6570-DK and STM32CubeIDE v2.1.0 to reproduce the issue. IOC file and code in attachment. Test code is in FSBL and it just blinks LED1 with 1 second period. When TIMPRE is 1 or 2, it blinks correctly. To reproduce: Change TIMPRE to 4 or 8 in clock tree and generate + build the code:Power up the board in development mode (BOOT1 = 1). On real application it only happens on cold boot. With this test code it seems to appears all the time.Launch the FSBL with debugger. Debugger should break at HAL_Init(). Press Run. Nothing happens. LED does not blink. Pause debugger and watch uwTick value:CPU is busy in TIM6_IRQHandler and with few seconds, the count has reached 489211. CPU is busy serving only the timer interrupt reques

I am using STM32CubeMX (Version 6.17.0). Here is what happened. I created a PIN name "CLK-A". After some troubleshooting, I found a mistake in my pinout definitions. I named the correct pin as "CLK_A". However, I did not delete the "CLK-A" pin. When the C code was generated for the project, the "CLK-A" pin was defined as "CLK_A" in the output C file. The tool did not flag me that there were two pins with the same effective name. It took me some time to track down the issue. Once I deleted original "CLK-A" pin definition, my design worked. I added "CLK-A" back to the design on another pin". I got "CLK_A<pin name>" in the "header.h" file. The first pin defined seemed to have priority.  

 Hi everyone,I am experiencing issues with Task Aware Debugging (FreeRTOS Task List) in the latest version of STM32CubeIDE. The "FreeRTOS Task List" view is either empty or not populating correctly, despite the scheduler running and tasks executing effectively on the hardware.Environment:IDE: STM32CubeIDE (Latest Version)MCU: STM32H7S3L8H6xFreeRTOS Version: V10.6.2 (CMSIS-RTOS V2 wrapper)STM32Cube 2.0.0Interestingly enough, the runtimestats itsef are working.Does anyone have similar issues?   /* USER CODE BEGIN Header */ /* * FreeRTOS Kernel V10.6.2 * Portion Copyright (C) 2017 Amazon.com, Inc. or its affiliates.

Hi,I added some follow-up questions to a message but I'm not sure if anyone will notice as I had already clicked "Accepted Solution" :-https://community.st.com/t5/stm32-mcus-security/stm32h5-simple-security-settings/m-p/885235/thread-id/9530#M9531Copying the questions regarding setting H5 security to be more like G4 RDP setting.1) Since the regression to open performs a full chips erase, am I right in thinking that we can use a common and not secure password? i.e. Revealing the password does not allow access to the firmware.2) Can I perform all of the steps listed, from my bootloader firmware? As far as I can see, the changes to product state just require a write to write to an option byte. I have yet to find the part of the reference manual that describes how to write the password file but looking through the scripts in the git repo mentioned seems to suggest that something is written to "address_password=0x8FFF000". (Just noticed - that address looks like H503 only, and for the H563

Hi,I'm working on STM32N6 with CubeMX + X‑CUBE‑AI to deploy a neural network model.The first AI model works fine: no compile errors, runs normally.When I replace the neural network model in CubeMX and regenerate code, I get dozens of compile errors (undefined reference, multiple definition, missing files, etc.).Clean project in IDEDelete build / Objects / Listings foldersReimport the new model in CubeMXRegenerate code completelyI have tried:But the issue still exists. It seems old AI files are not cleaned properly when changing models.Has anyone faced similar issues on STM32N6 when switching AI models with CubeMX + X‑CUBE‑AI?How did you solve this? Thanks for help.

why?

Hello,I would like to add Aliro compatibility to my access control device.My device uses the STM32WB55 MCU with an ST25R3911B NFC front-end.It seems that the X-Cube-Aliro package is designed to work with the new STM32WBA MCUs along with different NFC front-ends (such as ST25R200).As I understands it, I can implement the Aliro protocol on STM32WB55.1. Are there any such examples of adapting the X-Cube-Aliro package to work with such an MCU?2. Does using the X-Cube-Aliro package also require running a comm stack that the STM32WB55 doesn't support?3. Are there examples of implementing the Aliro protocol without using the X-Cube-Aliro package on STM32 devices?Thanks,Tal

I am recently retired and have used TouchGFX for my past job.  I typically run a Mac, so I decide to buy an inexpensive PC so I can do some development with TouchGFX.  I'm using a GMXtec NucBoxG3_Plus.  I've installed TouchGFX and it runs, but when I try to start a project using either the STM32F469I DISCO or the STM32H743I EVAL2, the progress bar increases to 88%, then hangs and the program exits.  I have about 400GB available on my SSD.  Any ideas?  Thanks

Hi all, I've been using CubeIDE for a little while and decided to build my next project using the STM32 VSCode extensions, which I am still figuring out. I am also figuring out CMake for the first time, as I let CubeIDE handle all the build details previously. In the past, CubeIDE let me add .h and .c files through the UI and automatically added them to the build process. I've found that I can make my own files and still build by manually altering the CMakeLists.txt file under the stm32cubemx directory, but I find myself editing the ioc file often enough that I'd rather not do this every single time I want to make a small change, and as the project size grows. All the drivers I've needed so far are part of CubeMX's middlewares, but if I do download a third party driver I foresee this becoming an issue there as well. Are there any workarounds to include manual additions to the generated CMake file? I'd like to utilize an STM feature if possible before I try making my own cmake file

Can someone explain the difference between tools and fonts in a simple way? Like when should I focus on choosing the right tool vs the right font for a project?    

Create a FreeRTOS project, keeping all settings at default configuration. Use CMake for building. The steps for creating the project are as follows:When the first task is initiated, a large number of recursive functions will appear in the function call stack.  

Hello ST Community,We are currently working on a project involving NB-IoT connectivity using the SIMCom SIM7022 modem, which is interfaced with the STM32L496ZG microcontroller via UART. Our goal is to establish MQTT communication with AWS IoT Core by sending AT commands from the MCU to the modem.Working Standalone Test:Before integrating with the STM32 MCU, we tested the SIM7022 module using a USB-to-TTL converter connected to a PC terminal. In this setup, the modem behaves as expected:Responds to AT commands properly (e.g., AT, ATI, AT+CSQ)Shows strong signal strength (AT+CSQ returns good RSSI)Registers on the NB-IoT network (AT+CEREG? returns +CEREG: 5,5)Connects to AWS IoT MQTT broker over SSL/TLS with certificate authenticationThis confirmed that the firmware version 2110B13SIM7022 works correctly and the modem is functioning properly.Issue with STM32L496ZG Integration:When we use the STM32L496ZG to send the same AT commands to the SIM7022 module through UART, the results are incon
