Hello,I haven't seen anyone else bring up this issue on here. I am trying to use the HAL ADC and USB at the same time but whenever i use HAL_ADC_Start_DMA() the USB becomes unrecognized by my computer. When I comment out the line that the HAL_ADC_Start_DMA() call is on the program works fine. Here is an example program I wrote to illustrate the issue. IDE Version: 1.18.1Part Number: stm32f072OS: Windows11/* USER CODE BEGIN Header */ /* USER CODE END Header */ /* Includes ------------------------------------------------------------------*/ #include "main.h" #include "usb_device.h" /* Private includes ----------------------------------------------------------*/ /* USER CODE BEGIN Includes */ #include "usbd_cdc_if.h" #include <stdbool.h> #include "usbd_def.h" #include "usbd_core.h" #include "stdio.h" extern USBD_HandleTypeDef hUsbDeviceFS; /* USER CODE END Includes */ /* Private typedef -----------------------------------------------------------*/ /* USER CODE BEGIN

Hi, I am using Nucleo-WBA65RI and I have enabled trustzone. I generated the project using CubeMX and it generated a secure and a non-secure project. I have enabled the trustzone option byte and am able to run an example project with secure and non-secure projects on my board. The problem is, I am not using CubeIDE for my project. I am using VSCode and am able to debug the secure project but it crashes when it is supposed to jump to non-secure project. And I am unable to debug the non-secure project. Can anyone provide me a working launch.json script using cortex-debug and stlink?  If my project behavior indicates some other problem, please suggest me a solution for that too. Thanks!

 Hello,I’m working with the STM32F767ZI board and have configured Ethernet (ETH) peripheral with LwIP middleware using STM32CubeIDE. After generating the code and trying to compile the project, I encounter the following error: arduinoCopyEditld.exe: cannot find .: Permission deniedThis issue started occurring only after enabling the Ethernet peripheral and LwIP middleware. Prior to this configuration, the project was compiling successfully.Steps Taken:Enabled ETH in RMII modeEnabled LwIP with default settings (static IP)Generated code using STM32CubeMXTried cleaning and rebuilding the projectAdditional Info:STM32CubeIDE version: [your version, e.g. 1.13.0]Toolchain: ARM-GCC (default from CubeIDE) Request:Could someone please help me identify why this "Permission denied" error is happening and how to resolve it? Also if the configuration has some other possible issue for ethernet not to work. I am attaching some conf images from cubeMX below     &

I am contacting you to report and request assistance with a recurring issue I am facing while working with the STM32G071CBT6TR microcontroller. I am experiencing problems with the bootloader during UART-based firmware uploads.The microcontroller programs successfully only the first time via UART using a USB-to-Serial converter (FT232RL). However, after a successful first upload, subsequent upload attempts fail, even though nothing changes in the hardware or the code.Technical Setup:MCU: STM32G071CBT6TRProgramming Method: UART (USART1) using USB-to-Serial (FT232RL)Baud Rate: 115200Parity: Even (as required by STM32 bootloader)Boot Mode Configuration:BOOT0 is connected to 3.3VReset pin is manually triggered before uploadSoftware: STM32CubeProgrammerPort Status: COM port opens successfullythe observed behavior: First Upload:Upload works perfectly with the default settings using STM32CubeProgrammer over UART.Following Uploads:All subsequent attempts fail with the following error:CopyE

When I write 1 at the position of EXTI0 (6) in the ISER of the NVIC, the value is written to both ISER0 and ICER0. What is the problem ? related to stm32f103c6t6.

Hi.I add the "x-cube-eeprom-v8-0-0" library to my project manually:I create folder Middlewares and copy sources the  folder as expected,I specify the paths in the project settings,I uncheck the "Delete previously generated files when not re-generated" on the Project Manager tab in Device Configuration Tool,but the folder is still deleted when regenerating after changing the any settings in ioc.What am I doing wrong?

With new and fast N6 MCU comes new CubeMX package which is full of bugs and errors, I spending hours to find and solve such problems, now I cant trust cubeMX at all, every function must be checked after code generation !ADC rank must be 7, but cubeIDE generate 1:I spent a lot of time trying to enable SPI DMA, when I tried to choose DMA handle I got unknown errors in almost all enabled interfaces (I2C, SPI, UART... ), and in some way after some changes elsewhere, closing, opening .ioc file form cubeIDE, and after next try the error is gone and I finally enabled !I trying to enable LSE, but because of some error with frequency settings which I cant set, I cant enable !There I cant find the way to enable DCMI DMA transfer, DMA handle for DCMI is not active, maybe I dont know some things there !?To get VDDCORE voltage and avoid errors every time after cubeMX generate code I added additional variable ADC_CHANNEL_VCORE, because cube generate ADC_CHANNEL_VCORE, but the correct varia

I am using STM32H755 microcontroller and STM32CubeMX V6.14.0 for my development.I am not able to set the clock frequency to 480MHz. Whenever I do so, I receive power regulator voltage scaling error.The product revision used by me is rev.V. The RCC parameter works only when the D1CPRE is set to 240MHz. And my requirement is 480MHz.Is there any solution to run the microcontroller at 480MHz.    

Hi, I want to get data from an ADC connected externally through SPI DMA whenever data ready pin is set. I want to do it without any interrupt handler, since our firmware have already loaded with other stuffs. I have tried the synchronisation of SPI DMA with GPIO EXTI trigger. It works when I configure SPI DMA in circular mode only.Because synchronisation doesn't triggers the SPI DMA it just syncs the process. I can't find any options to trigger the SPI DMA with timer or any event.How to trigger SPI DMA through GPIO EXTI event? Is that possible in STM32G4 series?. Thank you!     

Hello,I have been trying to flash firmware from one MCU to another MCU, and everything until actually jumping to the memory address where the firmware has been flashed to is working so far.Here's what I do in my code:I have the "Application" project, which is basically the firmware to be flashed. I build this project in STM32CUBEIDE, and then I take the application.bin file and convert it to a C array using some software. Then, MCU-1 uses that C array and flashes it to MCU2. MCU2 has 3 applications slots in its flash memory, and it flashes the bytes it receives to application slot 2 (0x08080000). Once it finishes, it jumps to the starting address of the second application slot using the following function:void BOOT_JumpToAddress(uint32_t address) { printf("Jumping to 0x%08X\r\n", address); // Function pointer to reset handler void (*app_reset_handler)(void) = (void *)(*((volatile uint32_t *)(address + 4U))); // Disable RCC, HAL, reset SYSTICK, and remap vector table offset HAL_R

Hello everyone,I am currently writing a GUI application with QT. The STM32CubeProgrammer API is integrated in the project. So far I was able to flash FW, use functions like massErase and execute without any problems  (All these over UART). Now my MCU needs the nBOOT0 option bytes to boot correctly.I have tried several times with the STMCubeProgrammer API function "sendOptionBytesCmd" but it does not work. I always get a "-6" as return value. Does anyone have an idea how to solve this ?This is what my code looks like.qDebug() << "Setting Option Byte nBOOT0 to 1"; int sendOptionBytesCmdFlag = sendOptionBytesCmd((char*)"-ob nBOOT0=1"); if (sendOptionBytesCmdFlag ! = 0) { disconnect(); qDebug() << "Could not set Option Byte nBOOT0 to 1"; } qDebug() << "Option Byte nBOOT0 set to 1 successfully! " << sendOptionBytesCmdFlag;Thanks in advance :)

Hi,when looking into the schematics of the STM32H735G-DK board (MB1520B), the Ethernet-PHY is connected via RMII.Now when I configure RMII for an STM32H7 in CubeMX, the interface pins do fit properly to what is used in the MB1520B schematics - except the RX_ERR-line. According to the schematics it is connected to PB10, but when I enable PB10 in CubeMX for use as RX_ERR, it is marked in yellow with the remark "no mode".So...how do fit both things together? How can I enable RX_ERR being used in Cube MX for RMII-mode?Thanks! 

I just installed the latest STM32CubeIDE 1.18.1 on a mac Studio M2 running Sequoia 15.5.  The default GNU make on the machine is /usr/bin/make, version 3.81.  The IDE is clearly creating makefiles for a later version of make, because building applications in the IDE errors out with "**** multiple target patterns" on a make rule that lists the elf and map files as targets.  I have make 4.4.1 installed via brew, but how to tell STM32CubeIDE where to pick it up is buried somewhere and I'm not seeing anything in any documentation.  Does anyone know how to fix this? 

Hi,I am currently using the following microcontroller (STM32F100C8T6B) in my design. I have built my project using the STM32CubeIDE (STM32CubeIDE Version: 1.18.1). I have created the following output files (BIN, HEX, and ELF) and I was able to RUN and download the source code onto my board (Design) using the STM32CubeIDE using the "elf"  file successfully. I used the Segger J-Link as a probe.If I used a different Flash Programmer such as STM32Cube Programmer or ST-Link instead of STM32CubeIDE to download the my code onto the board using the output files I created such as (.BIN, .HEX, .ELF or .SREC), it download onto the the board, the board doesn't not programmed or the download doesn't work.It appears that the board is programmed only whenever I use the STM32CubeIDE environment, not the regular Flash Programmers. The bottom line is that it works with IDE environment, but not with the regular Flash programmers are used. I am not sure what the problem is an

I have designed a board using the STM32U083KCU, i have programmed it once with a simple program made with STM32CubeIde that only prints "Hello\n" over USART2 on pins PA2 and PA3. I have flashed the chip over the same pins by holding the BOOT0 Pin high and power cycling it. It flashed it when it was blank. Now i tried to flash the full Program i wanted to upload and tried to upload it over the same method, using STM32CubeProg over UART2 on pins PA2 and PA3. I have held BOOT0 high. But it didn't flash, it said the Device is KO. I tried lowering the baud rates but this didn't help. I have tried to program it using SWD with a STM32Nucleo as the programmer. But the SWD doesn't connect to the chip. The STM works as it sends the "Hello\n" message to the computer if BOOT0 is low but for some reason also when BOOT0 is High. Is there a possibility to rescue the MCU ? Thank you for your time (:

Hello, I am new on the embedded subject, and I need some help.I want to practice I2C communication, so I connected Nucleo-L4P5ZG (master), and MAX6604EVKIT (slave), the general goal is to read registers and send the result via UART.I used the STM32cubeMX to generate the initial code.I used the HAL function " HAL_I2C_Mem_Read"  to read register in address 0x6.Build process went without errors.During debug, when looking at the scope, it seems that the MCU don't change the register address to 0x6, and it is stuck on 0x0.The slave address is correct, and I receive ACK (0 logic).I am attaching the main.c.Do you know what seems to be the problem?ThanksShay 

Hello,I am working on USB Device VCP project but I have problem about defines,index,etc. As you can see below that I have definition of "STM32N655xx" but I can not include "stm32n655xx.h".I tried Index, Rebuild step but it did not fix. On the other hand, I am also getting this problem for other files. My code is giving hardfault because it can not acces to "HAL_PCD_MspInit" while initializing "HAL_PCD_Init".I started getting code generate problems from .ioc file for N6 series but i will start new thread for this problem.Edit:I also forget to mention that CMSIS drivers outside of project folder as you can see below.I have "STM32N655xx" define inside of this projects but this folder can not acces to this symbol. If I can fix this, problem will be solved but I do not think that I have to do anything for this problem. Is this a bug? Thanks for help,Best Regards.

Hello.  I am trying to create a project that uses both the Nucleo GFX01M2 and SNK1M1 with the G071RB dev board. I want to configure my setup as a USB sink device. However, in STM32CubeMX I can select either the sink USBPD application, or the Touchgfx graphics application, but not both. What would be the best way to develop an application that utilizes both USBPD and TouchGFX?  Thank you. 

Hi guys,I m currently trying to debug my custom prototype stm32G474CEUx based project using stm32cubeide 1.18.1 version. But Once I set the breakpoint at particular line and then I try to step into it in debug mode,  then It would not go to that function inside, instead it goes somewehere. It seems bit strange. Previously it dd not happen. Actually i restarted the cubeIDE  but it did not work out.In fact previously my project was giving the correct result but after this issue, i am not getting the correct result on serial terminal.Can anyone please guide or help me for this.?  Many thanks in advance.!

Hi everyone ! first time poster, hope I'm doing it right.I'm working with an STM32F107VCT and using CubeMX to generate code.I have an issue with the RTC calendar, it goes back to 0 every reset which, if I'm not mistaken, it should not on a soft reset.I've found that in the MX_RTC_Init function, the date and time are set to the default values (see the CubeMX generated code below)./** Initialize RTC and set the Time and Date */ sTime.Hours = 0x0; sTime.Minutes = 0x0; sTime.Seconds = 0x0;   if (HAL_RTC_SetTime(&hrtc, &sTime, RTC_FORMAT_BCD) != HAL_OK) { Error_Handler(); } DateToUpdate.WeekDay = RTC_WEEKDAY_MONDAY; DateToUpdate.Month = RTC_MONTH_JANUARY; DateToUpdate.Date = 0x1; DateToUpdate.Year = 0x0;   if (HAL_RTC_SetDate(&hrtc, &DateToUpdate, RTC_FORMAT_BCD) != HAL_OK) { Error_Handler(); }Removing this piece of code solves the issue but since it is not user code, it is back every time I need to re-generated code.Am I missing something or is this

I would like to use SWV for debugging on the Nucleo-N657X0-Q board.I first enabled SWV debugging and also change the CPU clock to 400 MHz.   Then, I added some code to main.c (as reference here ).At the same time, I also set the core clock to 50 MHz in the TRACE configuration of Keil.But i can't see any string in Debug Viewer.Does anyone know what else I should check? Thank's 

Using cube IDE to debug my application i've witnessed breakpoints behaving unpredictably: sometimes they appear on their own in breakpoint list view while not present in the file editing view; other times the breakpoints i've just placed and just used dissapear.What can be a cause of such behaviour and how can i prevent it from happening?

I have imported several example projects into CubeIDE which don't show the header files. The header files do actually exist in the windows file explorer, and the project does properly build and run. So why don't these show up on the CubeIDE (Eclipse) project view? Is there some Eclipse setting that I am missing?

Hello,I'm new to STM32Cube-IDE (and Eclipse). Normally I use the ARM-gcc toolchain and do assembly coding.I managed to create a New STM Project by using the Example Selector tab in the Target Selection window.In this case it was the BSP Example for the B-U585I-IOT02A Discovery Kit (with the STM32U585 chip). After modifying the code in accordance with how-to-use-semihosting-with-stm32cubeide  the code runs OK. Now I would like to COPY the Project and edit that. From the multiple "how to clone a project" threads it appears that this is not trivial. (?) One of the threads I read was from 2022 and IDE version 1.8. It seemed that multiple otherwise experienced developers found it odd that this wasn't a straightforward task. Manually copying and search/replace seems very odd and error-prone.Has there been any progress on automating this?  In my case there aren't even any .ioc or .project files. As expected, the following don't work:Simply copying the P
