Hi all,I recently updgraded to STM32CUBEIDE 1.19 and GDB stopped working.The error is  I'm a Linux illiterate, and most to the posts seem to be Linux centrix.Any help is greatly appreciated!Thanks, Archer

Hi all,Whenever I try to create a new project for the NUCLEO-H7S3L8 board with the Project Structure set to Application only, I get the following error. I’ve already refreshed updates via Help → STM32Cube Updates and confirmed that my firmware repository contains the latest STM32CubeH7RS package.The project creation works only if I select Boot along with Application in the project structure. A standalone Application configuration always fails.Has anyone else encountered this? Is there a workaround to create an Application-only project for this board? 

After model analysis is performed on the model complexity using X-CUBE AI import, the code will be generated.Unknown type name 'ai_i8'Unknown type name 'ai_handle'Creation Failed. I'm getting 19 errors.Has anyone else encountered this? I think an update is needed.

hello, I usually design borad with stm32g474vet6, i use USB VCP as serial debug port, juse insert to usb port of PC, then can use printf to print debug information. this time, i want to use threadX OS, that is, AZRTOS, when i config AZRTOS with stm32cubeMX, i found you can only choose one item, if you use AZRTOS, you can not use USB VCP, if you use USB VCP, you cannot use AZRTOS.why?here is picture for choose item.i config USB port for Device and CDC, but cannot.Thanks, 

I have a customized pcb with stm32l476 as the mcu and stm32f103 as  a debugger. Since my debugger is not flashed i am using an external st-link from the nucleo-l476. When i try to connect it in the normal mode and reset mode, STM32 Cube Programmer gives me an error that DEV_TARGET_HELD_UNDER_RESET and when i try to connect it in hot plug mode, it connects but gives an error that NO DATA READ. What should i do?

HiI am trying to switch a project from one MCU to the another. I made a new IOC file in MX and then replaced the existing IOC file in my IDE project with my fresh file. The overall configuration is identical except for the pinout, and I use a mix of HAL and LL libraries. The Drivers folder is giving me a boat-load of errors, but all of my user code seems to be fine.I have tried cleaning/rebuilding the project, starting fresh with just the new IOC file, deleting the Drivers folder, saving and regenerating code, and more. The errors won't go away. I have attached the output.What can I do to fix this? Are there any common mistakes or recommended fixes for this situation?

Hello,I am using a custom bootloader for firmware updates on an STM32F7 series MCU.For my process, I need to check the maximum possible application size.Could you please guide me on how I can calculate the application size from the generated .bin, .hex, or .elf files?Also, how can I choose the slots to store the firmware.Thanks in advance!

Hi,Yesterday I found on YouTube a video from ST that showed how to read firmware from(!) an STM32 board to a pc using STM32CubeProgrammer. Today, I cannot find that video. Could someone from ST please point me in the direction of that video ? Thanks. Stuart

Hi everyone, History:I am running from bank 0 and I start an upgrade after the upgrade I do a bank swap and the application starts running from bank 1.Problems:Now I use a debugger to flash the .elf file in the micro-controller. But the code does not boot up. I open stm32 programmer uncheck the swap bank and re-flash the code and then the code runs.What I want:I want to uncheck the swap bank flag so that I am always in bank 0 when I flash my binary on the µC. I need to do it because I want to connect it in a CI/CD pipeline and I dont want the system to break.I want a script that ideally works jlink.exe to reset only the swap bank bit and not touch any other bit in the registerMy .jlink script:device STM32H573AI si SWD speed 4000 connect // Step 1: Check FLASH_SECSR for BSY, DBNE, WBNE bits (manual step, not supported in .jlink script) // Step 2: Clear error flags in FLASH_SECCR w4 0x4002202C, 0xFFFFFFFF // Step 3: Unlock FLASH and OPTION BYTES w4 0x40022008, 0x45670123 w4 0x4002

HiI’m currently working on a Nucleo board with BLE Mesh using the BNRG2A1 module. How can I implement BLE Mesh on this setup?"check out the X-NUCLEO-BNRG2A1 Documentationhttps://www.st.com/en/ecosystems/x-nucleo-bnrg2a1.html#documentation UM2992, "Getting started with FP-LIT-BLEMESH1 function pack for IoT nodes with Bluetooth® Low Energy mesh connectivity and lighting mode" would sound like a good starting point ... PS:See also The available Tools & Software; egX-CUBE-BLEMESH1, "Mesh over Bluetooth low energy software expansion for STM32Cube"FP-LIT-BLEMESH1, "STM32Cube function pack for IoT nodes with Bluetooth Low Energy mesh connectivity and lighting model"FP-SNS-BLEMESH1, "STM32Cube function pack for IoT node with BLE Mesh connectivity and sensor model" via: https://www.st.com/en/ecosystems/x-nucleo-bnrg2a1.html#tools-softwareHow can I add these software packages?These links show BLE Mesh support for the L476 Nucleo board.

HelloI am using STM32CubeIDEVersion: 1.19.0Build: 25607_20250703_0907 (UTC)OS: Windows 10, v.10.0, x86_64 / win32Java vendor: Eclipse AdoptiumJava runtime version: 21.0.3+9-LTSJava version: 21.0.3 When I include libraries into my stm32 project I drag and drop a folder (from the windows explorer) int the project predefined folder "Drivers". In a second step I need to set the paths for the C-compiler, C++ compiler and linker seperately.  To do so I open the procect preferences and add a path for the C compiler: In this case The project name is TST_CCS811. and the folder to add is DebugPrintf. I click ok. - path for this folder set.   I continue to do so for the C++ compiler and the linker. The path is always the same - it works - paths set.   Now I want to add the next folder in this case GPIO_CPP. To do so I click on the C compiler again but now - very strange - another project appears in this case TST_BME280 and not the TST_CCS811 which was

Working with CubeProgrammer connected to a Nucleo-G0B1RE board, a binary file needs to be stored starting from address 0x0800_C000 on the chip.  However, when the `Start Programming` is initiated, the process fails immediately as can be seen in the attached image.  The source file to be flashed is also attached as an archive.If the start address is changed to 0x0803_E000, then the download process says it completes.  All option bytes are at whatever the factory default is for this board.

I am using an STM32G431CBT6. I wrote code to toggle an LED in stm32cubeide. When I build the project in STM32G431, the LED stays permanently ON. However, when I power the board OFF and ON again, the LED starts toggling. Why is this happening?

In the STM32Cube_FW now is released project using "STM32CubeIDE".I can import the project to STM tools without issue.However, I have a new client which they are using "Eclipse" and does not want to make changes for project.Is there a simple way to import or convert the project which can be used ?I tried just import the project but did not work.Orphaned configuration. No base extension cfg exists for com.st.stm32cube.ide.mcu.gnu.managedbuild.config.exe.debug.1555957249 

Hi,I recently downloaded and installed en.st-stm32cubeide_1.17.0_23558_20241125_2245_amd64.sh.zip onto Debian Bookworm (fully updated). This proceeded without any errors or warnings.On starting the IDE, a blank (i.e. black window) was presented, within the Information Center tab, that did not list any documentation. When I used a previous version of the IDE, this tab then showed links to various documents. Has this functionality been left out of the current version of the IDE ?What do I now have to do in order to get the Information Center tab in the IDE to now show the links to the documentation ?Stuart

Hi everyone,I am currently working on the STM32N6570-DK board and trying to interface a camera to display the output on an LCD screen. I have run the provided example projects, and they are working fine.Now, I am creating a project in STM32CubeIDE and configuring peripherals in the .ioc file. However, I am facing an issue with the DCMIPP and CSI peripheral in the multimedia section. When I change certain parameters, such as the Physical Bitrate in CSI from 600 MHz to 750 MHz, the changes do not reflect in the main.c file.It seems that these parameters are being configured elsewhere. Could someone clarify where these settings are applied, or is this a bug?Also, I noticed that some configurations are present in the MX_DCMIPP_Init() function in this tutorial, but I couldn't find a way to configure them via the .ioc file in the DCMIPP peripheral, such as HAL_DCMIPP_CSI_PIPE_SetConfig.Do I need to set them manually, or am I missing something?I am attaching my project for your refe

I have the following settings in Cube Mx for TIM1The TIM1 is used for PWM generation, but the slave mode, trigger source, clock source are disabled then how Tim1 receives the clock for pwm generation.For TIM4 it is clearly statedSo i assume it will be taken from APB2 timer clock.One final questionIt is mentioned TRGO2 as above but how do i know it is connected to what? Please help.

I am working with the STM32C092CCTx microcontroller and have configured USART2 in asynchronous mode using STM32CubeMX. The system clock (SYSCLK), HCLK, and PCLK1 are all set to 48 MHz. USART2 TX/RX pins are correctly assigned with their alternate functions, and the peripheral is initialized using HAL.However, I do not see the USART2 clock source (clock mux) option in the Clock Configuration tab. I would like to confirm whether, for this STM32C0 series device, USART2 is fixed to use PCLK1 as its clock source — and whether the absence of the clock mux option is expected behavior in CubeMX for this MCU.Despite calling HAL_UART_Transmit() with valid parameters and configuring the baud rate to 115200 bps, I am not observing any data on the TX line. All clock and GPIO configurations appear correct. Could this be related to an internal clocking issue, or is there another possible misconfiguration I should look into?Any guidance on this would be greatly appreciated.

Hi allFor the STM32U5, the reference manual shows the GCCFG register as but STM32CUBEIDE showsbit 16(and a lot of other bits) are differing. Is this an error and if so which is the right one 

I've just bought this board: https://www.st.com/en/evaluation-tools/nucleo-f767zi.html and when I start programming the board using STM32CubeIDE, I've run into this error: So I've searched how to fix it, I've used STM32CubeProgrammer to do a full-chip erase, but still failed:So what should I do next to make this new kit work? 

Hi all,Recently I faced pretty bug in the HAL implementation. I am using STM32F103 with CubeMx 6.12.1 HAL, (but inside the SPI C-code I saw 2016th year).SPI configured as Full-Duplex slave (using HW NSS, but it's doesn't matter).Sometimes I had to abort a transaction, and after the abort I got HardFault.Bug repeat sequence is:1. Start SPI Rx over Interrupt2. Abort Rx3. Start SPI Tx over interrupt4. Wait for receive all bytesAfter figuring out, I found, that Abort handler does not clear SPI_CR2_TXEIE and SPI_CR2_RXNEIE flags in the SPIx_CR2 reg.Therefore, after start Tx after Rx aborted, hspi->RxISR clears to NULL, but opposite TXIE flag kept set.Then on an any byte completion the condition on stm32f1xx_hal_cpi.c:2447 appears true, but hspi->RxISR already set to NULL, which raises HardFault.My proposal is:1. Clear xxIE flags during Abort (to fix exact this bug)2. Use HAL_SPI_ErrorCallback instead of NULL everywhere when hspi->RxISR and hspi->TxISR is setting to state wh
