STM32 MCUs Software development tools

On (up-to-date) Windows10-64 machine, I just downloaded and installed (for first time) STM32CubeIDE.  (Up to date Norton) reports the following "High Threat". Details below.  The last reference I can find by googling this error goes back to 2020, and was apparently fixed.Before I click the "make exception" option (or just delete the installer), I want to make sure a true virus hasn't somehow snuck into the current release. -bob ____________________________DetailsThreat name: IDP.GenericThreat type: Miscellaneous - This is an app that you may have unknowingly installed and that may harm your computer performance.Status: Threat detectedDetected by: Behavioral ProtectionOn PC from: 2/27/25, 10:02 AMLast Used: 4/8/25, 9:33 PMStartup Item: YesMany usersThousands of users in the Norton Community have used this file.MatureThis file was released a month ago.HighThe file risk is high.____________________________OriginLocation: local://*C:\Users\rober\Downloads\en.s

STM32G474RET – When I try to set up a DMA, I get this message: “No available DMA request for this peripheral.”I haven’t configured any other DMA.With a different MCU, it worked fine before.I’m using CubeIDE version 1.16.0. Any ideas would be really helpful, as I’m new to STM32. 

Hey all.As per tradition, my first post in this community will be a question.In the same way that I can run pre- and post-build commands that is run when I build a project in STM32cube, is it possible to run a post code generation command when I generate code from the .ioc file?- Moose

Hi When I use stm32cubemx V6.15, I find that enbale OSPI as QSPI mode is not feasible.It say another Quad spi is activated, but actully not.When downgrade to V6.14, I can enable Quad spi.Can you help confirm this issue?

I am using a MacBook M1 Max (Sonoma 14.6.1) and STM32CubeIDE(1.16.0) with a STM32g0316-disco board.   Everything was working fine until, out of the blue, I started getting LibUSB errors when I tried to flash/debug my code.I tried a second identical dev board and new cables and every usb-c port on my Macbook and the error persists. I brought the machine up in safe mode and the error is still there.  Here is the Error message from the IDE.libusb: warning [darwin_open] USBDeviceOpen: another process has device opened for exclusive accessDevice connect error Error in initializing ST-LINK device.Reason: libusb: warning [darwin_open] USBDeviceOpen: another process has device opened for exclusive accesslibusb: info [darwin_claim_interface] no interface found; setting configuration: 1libusb: error [darwin_claim_interface] could not set configurationFailed to connect to device.

Before the STM32CubeIDE had serious issues with the live expressions during debug, with variables showing random values and signs when they were unsigned (the issues are various years old now https://community.st.com/t5/stm32cubeide-mcus/stm32cubeide-1-18-0-released/m-p/778624#M34678) After updating to STM32CubeIDE Version: 1.18.0 Build: 24413_20250227_1633 (UTC) the live expressions completely broke All the variables now show 0 and they won't vary As you can see from the screenshot, hovering while on breakpoint shows the correct value. On the top right, all the values are 0 in the live expressions tabThat's pretty bad considering, trying to migrate to VSCode for being able to debug, gives another sort of issue, acknowledge by ST itself https://community.st.com/t5/stm32-vscode-extension-mcus/stm32-vs-code-extension-no-compiler-found-in-cache-file/m-p/781619#M640 What happened to this company lately...? All these bugs had been unusual ba

Hi, The mbedTLS v3.6.x is LTS version and released for quite long time. Do you have plan to upgrade mbedTLS to v3.6.x with MX? If not, customer shall manually integrate/upgrade the mbedTLS to v3.6.x. Could you please give me a guideline to do that. Thanks!

Hello, Using the latest CubeMX 6.15.0 I was generating ThreadX for Secure - Non Secure Project (for STM32N6 - Cortex_M55). This did not add file : "\Middlewares\ST\threadx\ports\cortex_M55\gnu\src\txe_thread_secure_stack_allocate.c" and so is not added in to the CubeIDE project. Where as it's counterpart - "\Middlewares\ST\threadx\ports\cortex_M55\gnu\src\txe_thread_secure_stack_free.c" is getting generated and added to the project. Also, compiler includes like "/Secure_nsclib" , "/Drivers/CMSIS/Include" did not get added into the Compiler Include Paths in the CubeIDE project that this CubeMX generates. 

Hello everyone,I understand that  bundle manager replaced STM32CubeCLT  with "New STM32Cube for Visual Studio Code extenstion".Is there an option to download the bundles outside VSCode environment for offline installation? Similar to STM32CubeCLT?Rationale here is to use the same toolchain in an headless automated build system with no internet connection.Thanks

BackgroundI have developed firmware for a LoRaWAN device by modifying the LoRaWAN_End_Node example for the B-WL5M-SUBG1 development board, which was extracted from the STM32Cube MCU Package for STM32WL series (v.1.3.0) from ST's website (not through CubeIDE). Based on this, I have further developed a custom PCB containing the STM32WL5MOC and other peripherals (antennae, RTC, LEDs, buzzers, etc.). SituationTo test the custom board, I have flashed the STM32 chip with a simple firmware which toggles the GPIO pins based on button presses - this works as intended. However, when I flash the LoRaWAN_End_Node example for B-WL5M-SUBG1 (downloaded from STM32CubeIDE v.1.18.1) onto the STM32 chip, the device was able to join the LoRaWAN network once, but failed subsequent joins due to a repeated nonce. After numerous failed attempts at fixing this, I went back to the example code downloaded from CubeIDE, and now my LoRaWAN server cannot even receive a join request.When looking at the current

After editing the .IOC file, the code generator will mess up the app_usbx_device.c\MX_USBX_Device_Init() function by placing the codeif (ux_device_stack_initialize(...)right after the variable declarations at the top of the function.Typically, that function call should be around line 151 after 6 other function calls initialize all the pointer variables.The end result is 8 compile warnings about using uninitialized variables.Attempts to wrap the stack initialization in /* USER CODE BEGIN MX_USBX_Device_Init0 */ don't work, and the code generator will just move it to the top of the file anyway.What is the work-around for this?STM32H562VGTxSTM32CubeMX 6.12.0STM32CubeIDE 1.16.0 

Hoping someone could help.  I did a full erase on the stm32h747i_disco from the stm32cube programmer.  I attempted (several times) to upload the STM32Cube_Demo-STM32H747I-DISCO-V1.0.0_FULL.hex and got the following error:14:09:58 : Opening and parsing file: STM32Cube_Demo-STM32H747I-DISCO-V1.0.0_FULL.hex14:09:58 : Memory Programming ...14:09:58 : File : STM32Cube_Demo-STM32H747I-DISCO-V1.0.0_FULL.hex14:10:00 : Size : 58.38 MB14:10:00 : Address : 0x0800000014:10:00 : Download in Progress:14:10:04 : Error: failed to download Sector[0]14:10:04 : Error: failed to download the File14:10:05 : Memory [0x08000000 : 0x08200000] - Checksum : 0x139CE03CDoes anyone have a suggestion?

When generating code for Makefile, the MacOS version 6.15 succeeds while the Linux version 6.15 fails.I have the same version of firmware packages installed on both OS.MacOS STM32CubeMX produce this following snippet in the Makefile####################################### # LDFLAGS ####################################### # link script LDSCRIPT = STM32U5a5xx_FLASH.ldand do copy the correct file to the project directory. However, the Linux version fail to define linker script file and does not copy required script to the project folder. ####################################### # LDFLAGS ####################################### # link script LDSCRIPT = The log explains why, the file does not exists.No such linker file: /home/mike/STM32Cube/Repository//STM32Cube_FW_U5_V1.8.0//Drivers/CMSIS/Device/ST/STM32U5xx/Source/Templates/gcc/linker/STM32U5a5xx_FLASH.ld No such linker file: /home/mike/STM32Cube/Repository//STM32Cube_FW_U5_V1.8.0//Drivers/CMSIS/Device/ST/STM32U5xx/Source/Template

Board:STM32U5A9xxI set the Number of PDO to define = 5 in the cubeide.But after generate code, the code in usbpd_pdo_defs.h, macro:PORT0_NB_SINKPDO is still 1U.I also checked the file usbpd_pdo_defs_u5.ftl in cubeide's location, the macro PORT0_NB_SINKPDO is a value param from cubeide indeed, but it seems not effective. Is a bug?/* Define ------------------------------------------------------------------*/ #define PORT0_NB_SOURCEPDO 0U /* Number of Source PDOs (applicable for port 0) */ #define PORT0_NB_SINKPDO 1U /* Number of Sink PDOs (applicable for port 0) */ #define PORT1_NB_SOURCEPDO 0U /* Number of Source PDOs (applicable for port 1) */ #define PORT1_NB_SINKPDO 0U /* Number of Sink PDOs (applicable for port 1) */ 

The goal is to test the Adafruit Gamepad QT with the Nucleo-G071RB board. This requires using the Adafruit seesaw C++ library of source files, which transmits analog joystick signals using the I2C protocol.I used the code example I2C_TwoBoards_ComPolling (C-code) as a starting point an...Added both the Adafruit seesaw and BusIO libraries (C++ code) to the project,Updated the Project Include paths,Added the library paths to the Project Source Locations (Figure 1), andRenamed the main.c file to main.cpp.Problem: the project does not built the Adafruit libraries, the compiler just ignores them.What is the solution for this? How do I build the entire project, including the Adafruit libraries? Thank you!!!Figure 1. 

Working with getting TraceRecorder to work with an L562 project.  When the tracerecorder software is added (using the package), SYS_DBG_ENABLE_TA4 is set to 0, which inactivates the feature.  SYS_DBG_ENABLE_TA4 has to be manually set to 1 to enable the feature.  So far, so good.  Get it working, and then decide to make a change to the .ioc file.  exit configurator.SYS_DBG_ENABLE_TA4 is reset to zero.If it is set, PLEASE leave it that way, since it makes no sense to reset it.  Amazing the number of errors you can get on default settings (like streaming mode taking almost half a megabyte of memory or more).I'm regarding this as a bug.Thanks.

 After updating to STM32CubeMX 6.15.0 with STM32CubeWBA FW V1.7.0 for the STM32WBA63CIUx, I noticed a change in how the HAL tick is driven.In MX_APPE_Init() (generated in app_entry.c), CubeMX now creates a UTIL timer to increment the HAL tick: /* Create an RTC based timer to trigger HAL tick increment */ UTIL_TIMER_Create(&TimerHALtick_Id, HAL_TICK_FREQ_100HZ, UTIL_TIMER_PERIODIC, &TimerHALtickCB, 0); uwTickFreq = HAL_TICK_FREQ_100HZ; /* Start HAL tick timer */ UTIL_TIMER_StartWithPeriod(&TimerHALtick_Id, HAL_TICK_FREQ_100HZ);This runs at 100 Hz by default and causes my system to wake every 10 ms.Previously, I used TIM17 for the HAL tick, with FreeRTOS (tickless idle) and STM32_WPAN BLE, and it worked well. Now, I see both TIM17 and this new UTIL timer, which leads to unnecessary wakeups.My questions:Is there official documentation on this new HAL tick implementation using UTIL_TIMER?How can it be configured or disabled via STM32CubeMX instead of modifying the

Hi there,According to the STM32H755 datasheet, the Cortex-M7 frequency can reach up to 480MHz.However, when I configure the sysclk in STM32CubeMX, it shows the maximum frequency is 300MHz.What's wrong with my config? Or is there any misunderstanding by me?Thanks for your help!  

My colleague is working with the stm32h743.Initially PC7 was setup as a PWM output.  That worked fine.When he changed the pin to GPIO_output, no code was produced to set up the pin.By manually entering code, we could get the pin to be configured as we want.  But no matter what we tried, the IDE would not generate configuration code

  I have been trying to deploy a simple ML model on my STM32 NUCLEO H755ZIQ, i've been following a tutorial as am learning right now, but no matter how many times i try i cant seem to shake of these three errors:1. when i try to open the XcubeAI  interface a dialogue pops up saying setting up USART3 but it never stops loading, i suppose its a bug but i leave it to the experts to decide what it is. 2. when i try to validate the code on target board, it gives an error: E200(ValidationError): TARGET: Unable to bind the ST.AI runtime with "network" c-model: []E801(HwIOError): Invalid firmware – /dev/cu.usbmodem11403:1152003. When am trying to build the model i got this error: error: unknown type name 'ai_i8'error: unknown type name 'ai_handle'fatal error: bsp_ai.h: No such file or directoryPlease help me out and guide me how to run this basic project on my board i found on the internet: https://github.com/stevemac321/5_Class_Embedded_Keras/tree/maini

Hi,i just generated a project using the Device Configuration Tool (1.19.0). All works. But as soon as I enable "Generate peripheral initialisation as a pair of '.c/.h' files per peripheral" the hardware stands at:static HAL_StatusTypeDef USB_CoreReset(USB_OTG_GlobalTypeDef *USBx) { __IO uint32_t count = 0U; /* Wait for AHB master IDLE state. */ do { count++; if (count > HAL_USB_TIMEOUT) { return HAL_TIMEOUT; } } while ((USBx->GRSTCTL & USB_OTG_GRSTCTL_AHBIDL) == 0U); count = 10U; /* few cycles before setting core reset */ while (count > 0U) { count--; } /* Core Soft Reset */ USBx->GRSTCTL |= USB_OTG_GRSTCTL_CSRST; do { ////loops forever here?!?!?! count++; if (count > HAL_USB_TIMEOUT) { return HAL_TIMEOUT; } } while ((USBx->GRSTCTL & USB_OTG_GRSTCTL_CSRST) == USB_OTG_GRSTCTL_CSRST); return HAL_OK; } I had no closer look into what is done differently. Just wanted to report the issue. Again, if everything is inside of

Hi, 1. I want ti have auto view change for C, MX and Debug windows. Previously a promt used to come. Now I dont see that.2. I want to generate MX automatic on save. Previously a promt used to come. Now I dont see that. 

I am porting code from an existing project that runs on an STM32F4 chip onto an STM32H7 chip, and have been losing my sanity for a couple of days trying to get over hurdle #1: I use a UART for communicating with the chip, and have not been able to get DMA transfers to work. I used CubeMX to create a new project for the new chip. Based on https://community.st.com/s/article/FAQ-DMA-is-not-working-on-STM32H7-devices I have confirmed that the buffer that I've pointed the DMA peripheral at is indeed sitting in SRAM2 (D2 area), which it should have access to. For fun, I'm not enabling the data cache, and am not fiddling with the MPU yet. Using HAL_UART_Transmit() with no DMA works fine, but with DMA the transmit function runs once, no data is transferred, and the port stays busy forever. Resetting the port status will let the function run again, but still doesn't transfer any data. No error flags get set, and no interrupts get called (e.g. TxHalfCplt or DMAError), the transfer just doesn't h
