STM32 MCUs

Version 6.16.1I have identified a number of bugs - collecting them here.  Note that these are time wasters, but there are workarounds - so they are not critical but would definitely aid in the usability/productivity of users.-If you use the XCube.AI software package to generate a template application, the template application will not build.  To fix it you have to add      #include "ai_platform.h"  at the top of the file under the other existing includes.-In the configuration for the individual networks for the XCube.AI, if you select the first profile "internal-memories-only--default" it will hang when analyzing and never complete.  The workaround is to use the n6-noextmem option which appears to accomplish the same thing-When first starting up CubeMX, when you select the XCube.AI option (the actual selection of the components for inclusion), even if you have  "FSBL" selected for the context, many times it will add it with ExtMem context in

quectel bg96 does not reply to messages from stm32l496ag on kit board p-l496g-cell02 but since I bought it. I could not even start blink the led on bg96 so I assume there is something missing to me. I use usb cable to stlink com and debug from the software but never had a response from bg96 after sending at commands. What I can do about? thank you. Marcello

I used CubeMX to generate the "LoRaWAN_AT_Slave" example for the B-WL5M-SUBG1 board.I had some issues with it waking up from sleep and upon a few hours of debugging i found that the LSE Driver Config was set to LOW in the example application, but the datasheet recommends HIGH.Just letting other people with the same issue know and hopefully the ST-Team can fix the example configuration in future releases.

Hi, I am using the STM32L4 B-L475E-IOT01A board with Wi-Fi module Inventek system ISM43362-M3G-L44.I have seen the example WiFi projects but they do not have the .ioc file. So my question is, is there any middleware available in STM32CubeMX which can help me implement WiFi connectivity via USART? The communication interface between the stm32 board and the WiFi module is SPI3 by default but the documentation says that use of USART3 is also possible, and USART3 is what I want to use.So any easy ways to do that? Any available middleware in CubeMX? Or is any example project available online?Thanks!

I am currently evaluating microcontroller options for our project and need your support in identifying a suitable MCU.Our key interface requirements are as follows:   2× MDIO interfaces,3× I2C bus interfaces If you could recommend an MCU that supports these features or share any relevant technical details/datasheets, it would be very helpful.If not, please also suggest alternate part numbers that can meet this requirement.

I have developed a custom board for STM32F469NIH6 and is loosely based on STM32F469i-DISCO, it uses an external QSPI Flash memory type MT25QL128A as does the DISCO board. For this setup I am using ST supplied external loader MT25QL128A_STM32F469I-DK.stldr which works fine.We have a requirement for a processor with a video codec, so the logical upgrade route is to STM32F769NIH6 to be used with external QSPI flash MT25QL512A. Both of these devices are pin compatible with the above MCU and QSPI, so the plan is to use the same custom PCB.The problem comes in writing an external loader for this combination because.While ST have a loader MT25QL512A_STM32769I-EVAL.stldr, this loader is not working in our setup, probably because of alternative QSPI I/O configuration which would likely be easy to alter in the loader code, however the source code is not in the github repository https://github.com/STMicroelectronics/stm32-external-loaderIs it available elsewhere?UM0892 says that the ST loade

I am experiencing issues powering the STM32H755ZIT6 MCU on our custom board. The schematic has been derived from the NUCLEO-H755ZI-Q development board reference design, and we have verified that there are no apparent design or assembly errors. However, the MCU fails to power up as expected.   All VDD pins are connected to an external 3.3 V supply (VDD_MCU). For the power supply configuration, we selected the default internal SMPS-only configuration, identical to the NUCLEO-H755ZI-Q board, as detailed below: VDD_MCU is connected to VDDSD (pin 16).VLXSD is connected through a 2.2 µH inductor to the VDDLDO pins (70, 105, 143) and the VCAP pins (68, 103, 140).In CubeIDE, PWR_DIRECT_SMPS_SUPPLY is selected under RCC > Power Parameters > Supply Source.Power Regulator Voltage Scale 3 is selected under RCC > Power Parameters > Power Regulator Voltage Source. When powered from the external 3.3 V source, both VDD_MCU and VDDSD are at 3.3 V; however, there is no voltage present a

I am a fan of STM32, especially the peripheral sets offered are great. Over the years however, one type of peripheral is missing which would be a great help for many projects, this is a programmable logic cell.Such a cell would contain elements like Flip-Flops, Look Up Tables and such that can be configured for specific functions. For instance using the LUT's, it would be possible to create all kinds of logic operations like AND, OR, XOR gates.Using the Flip-Flops, I would be able for instance to create a clock gate, which I needed in my last project. There I needed an external clock signal to propagate to other peripherals and be able to enable/disable this. In the end I manage to create this function with a timer but this unfortunately generates something like 9 clock cycles of latency limiting the maximum frequency of the external clock signal. A basic Flip-Flop solution would probably introduce a much smaller latency.Competing products offer this kind of functionality more and more

Hi ST Community,I am new to ST and hope to find a fast solution on this way. Background:I am working on a hobby project and want to drive a BLDC Motor. Once I flash the SW on the target, Overcurrent Protection is hit immediately (can see on debugger and Motor Pilot (in MCSDK). Target: Custom Board based on EVSPIN32G4 Schematic (EVSPIN32G4)Chip: STM32G431VBx3. Workflow: 1.) Board Designer done over Motor Control Workbench2.) New Project created and .ioc file generated3.) Generating the Code over MX Cube (without touching any config)4.) Start Motor Pilot or Debugger -> results in overcurrent protection (PWMC_OCP_Handler() is triggered immediately and OverCurrentFlag is set to true.) My Assumption:1. It is not an HW issue because I removed the Motor from the Board so there can no big current flowing.2. I can see in MX Cube that not all of the Pins are configured from MC SDK, is that normal? Do I need to configure the missing pins (only related to motor con

Environment DetailsMicrocontroller: STM32C091CBTx (LQFP48)STM32CubeMX Version: 6.14.1LL-DriverConfiguration: An STM32CubeMX project is configured for an STM32C091CBTx MCU, with DMA channel 6 assigned to a peripheral (ADC).Generated Code (stm32c0xx_it.c): Upon code generation, CubeMX creates the shared interrupt handler for DMA channels 4, 5, 6, and 7 in the stm32c0xx_it.c file. The function is defined as:void DMAMUX1_DMA1_CH4_5_6_7_IRQHandler(void)Startup File Vector Table (startup_stm32c091xx.s): However, the default startup file provided with the project contains an incorrect entry for this interrupt vector. The handler name in the vector table is listed as:DMAMUX_DMA1CH4_5_IRQHandlerConsequently, the `DMAMUX1_DMA1_CH4_5_6_7_IRQHandler` function is never invoked when an attempt is made to trigger DMA Channel 6.Confirmed WorkaroundThe issue can be resolved by manually editing the startup file:In the `startup_stm32c091xx.s` file,Search for the incorre

Hi,I have project for STM32F405 created manually. Project is using fixed GCC 4.92014q4.After updating STM32CubeIDE to version 1.14.0 i got warnings shown below.Compiler option "Cyclomatic Complexity" is disabled.File "subdir.mk" contains this rule:# Each subdirectory must supply rules for building sources it contributes Src/%.o Src/%.su Src/%.cyclo: ../Src/%.c Src/subdir.mk How to remove this warnings?

Hello All,I am current testing STM32U375RGT6Q at 80 degrees and I see that there is significant increase in the average current consumption at 80 degrees C. Average Current consumption increases from 290uA to 1mA. Also note that1) Pull up and Pull down are 1Mega2) MCU is in sleep mode for 50 percent of the time.3) Internal oscillator MSI is used at 3MHz4) Flash memory is 1MB5) SMPS mode is used to reduce the current consumption.Is there a way out to reduce the current consumption at high temperature. I know that STM32L4 series are more stable over temperature but they dont suite the current budget of 300uA 

Hi,I just noticed that CubeProgrammer v1.21.0 always shows me an update notification, but it is already the latest.Restarting the Cubeprogrammer or the operating system does not make any difference. Environment:- Windows 11- I have installed v1.21.0 alongside v1.20, but that should not make any difference, or would it? 

Hello STM32 friends!I've previously used USB on an STM32G474RET6, and it was initialized with the function:MX_USB_Device_Init()The goal is to use it as a USB serial port to communicate with my device, and that worked.Now I'm using the STM32U5G7VJT6, and this time, the USB is initialized with the function:MX_USB_OTG_HS_PCD_Init()But this function hangs.I've enabled USB interrupts in the STM32CubeMX, but that doesn't help.I haven't been able to isolate the problem yet, but it's probably something very simple.Is this another new USB library?As requested, I attached my IOC file.What could be the problem?Sincerely, Jack

The STM32Cube CMake Support extension treats workspaces as STM32Cube projects when a folder higher up in the directory tree (above the workspace folder) contains the files .settings/bundles.store.json and .settings/bundles-lock.store.json.For example, given a tree like this:/ ├── .settings │ ├── bundles.store.json │ └── bundles-lock.store.json │ └── path └── to └── generic_cmake_project ├── CMakeLists.txt ├── generic_cmake_project.code-workspace └── lib.cIf the user opens the workspace generic_cmake_project.code-workspace, the STM32Cube CMake Support extension automatically creates the file .vscode/settings.json with the following content:{ "cmake.cmakePath": "cube-cmake", "cmake.configureArgs": [ "-DCMAKE_COMMAND=cube-cmake" ] }and modifies the generic_cmake_project.code-workspace file by adding the following settings: "settings": { "stm32cube-ide-clangd.path": "cube" },On the other hand, if the user opens the workspace in "folder mode" (File > Open Folder...), the STM3

There's a bug in latest STM32CubeMX v6.16.1. When enabling RAMCFG for Appli on STM32N6 MCU, the IOC file becomes unloadable.I attached the demonstration IOC file. I created new project for STM32N6570-DK board, enabled RAMCFG peripheral for Appli, checked the AXISRAM3-6 areas, defined single continuous area for those SRAMs in MMT and saved the project. After this CubeMX fails to load this IOC file. I get popup:In textual form the error is: Cannot invoke "com.st.microxplorer.mcu.memorymap.MemoryMapService.getInRangeAppRegions(long, long, com.st.microexplorer.mcu.Context)" because "this.mMemoryService" is null.The workaround is to not enable RAMCFG in CubeMX, rather control the peripheral manually.

I have a problem with the RTC initialization on the STM32WB05TZF6TR (BGA package).  When the board is powered on, the MX_RTC_Init() function calls HAL_RTC_Init(), which returns with HAL_ERROR status.I traced the problem to the stm32wb0x_hal_rtc.c file, inside RTC_EnterInitMode().  It attempts to set the INIT bit, and then waits until the INITF bit changes state to confirm that Initialization Mode has been entered.However, the INITF bit never changes state, so the while loop times out. On my custom board, I have confirmed that this error always occurs when power is applied to the board, but if I manually reset the MCU while power is already applied (by shorting RESET to GND momentarily), then the initialization will complete successfully.To eliminate anything specific to my board, I generated a very simple test project (attached), which uses the default clock configuration with internal oscillators only, for both High Speed and Low Speed clocks.  The ONLY configurati

I created a sample project using the STM32N657-DK, but when I try to debug using ST-LINK, each project does not work and results in a HardFault or similar error.I also tried loading them simultaneously from the debug configuration, but it was not successful.How can I properly debug both AppliSecure and AppliNonSecure? Also, is this the correct way to create a sample using the TrustZone feature of the STM32N6570-DK?I would appreciate your guidance.I am using STM32CubeIDE version 1.19.0.For the sample project I created, I made "FSBL", "AppliNonSecure", and "AppliSecure".

Hello, I am beginner with STM32.I have some radiosonde boards with an STM32L051R6T6. I use STM32CUBE IDE V2.0.0When I start a project, select the appropriate MCU, there is no Core directory and no ".IOC" file.So, it is impossible to access to the GPIOs.I've tried some ways to do that and allways unseccessfull. Please, have you an idea ? NoticeI use also an STM32F103C8T6 board.  I've create my own GPIO lib, my own I2C lib,  and I can compile, flash, debug and run my program. Thank you and sorry for my english  Retired
