Hi everyone, I'm currently working with one NUCLEO-F767ZI board and everytime I create a new project on STM32CubeMX this "Error Downloading the following files: crdb_full.zip (Cannot unzipped)" appears. I already tried to reinstall the STM32CubeMX and delete the crdb_full.zip file at <userfolder>\.stmcufinder\plugins\mcufinder\mcu\cs as suggested in another post.I attempted unzipping the crdb_full.zip manually but it seems that there is an error with the file itself. Is there any solutuion or workaround to solve this problem? Is this affecting the build?

I am trying to configure B-L072Z-LRWAN1 using STM32CubeIDE. According to my research, I need to download and use the End_Node project from the STMicro website, but when I try to do so, I get the following error."The selection cannot be launched, and there are no recent launches"I followed the instructions on the following website. Do you know how to solve this problem?https://docs.antares.id/en/code-and-library-examples/stm32-lora-stm32cube-ide/sending-simple-data-to-antares

Hi,I am trying to install the cube programmer, but keeps failing at step 7 and restarts the installer each time. This is the error I am seeing:com.izforge.izpack.api.exception.IzPackException: An error occurredin java.lang.Thread.run() at Thread.java:750in com.izforge.izpack.installer.unpacker.UnpackerBase.run() at UnpackerBase.java:267in com.izforge.izpack.installer.unpacker.UnpackerBase.unpack() at UnpackerBase.java:339Caused by: com.izforge.izpack.api.exception.InstallerException: File execution failedin com.izforge.izpack.installer.unpacker.UnpackerBase.unpack() at UnpackerBase.java:319in com.izforge.izpack.installer.unpacker.UnpackerBase.unpack() at UnpackerBase.java:513in com.izforge.izpack.installer.unpacker.UnpackerBase.executeFiles() at UnpackerBase.java:989I am installing as Administrator, if that information helps.Thanks!

Hi,I'm using V6.15.0 of CubeMX with STM32U5 to generate DMA code. When I use the following configuration, it appears to generate incorrect code?I've noticed the following:1) It placed the Node_GPDMA1_Channel1 structure on the stack:This doesn't seem right, and I would note that when memory to memory DMA is selected, it allocates this (correctly) statically.2) It sets the source increment mode to LL_DMA_SRC_FIXED: This again doesn't seem right. When transferring from memory to peripheral, the source increment mode should be LL_DMA_SRC_INCREMENT. 3) This code is confusing and inconsistent: When generating memory to memory code, the LL_DMA_SetLinkedListBaseAddr call is placed inside the comments. When generating peripheral to memory code, it is placed outside of the comments. Regards John 

Hi,In the bundles manager for my project is it possible to view at a glance items where there is an update available? Currently the status column icon doesn't differentiate between updatable items - only when I open the version drop-down does it become clear there are newer version(s) available (or I select all then hover over the update button).Also, same goes for "cube pack list" command - can this show a list of updatable items?Thanks.

I am using the STM32Cube VS Code extension (Preview) with the official ST-ARM-CLANG and clangd for code completion. Just ran into two issues:1. Incomplete --query-driver config breaks C++ IntelliSenseThe extension adds--query-driver=${env:CUBE_BUNDLE_PATH}/st-arm-clang/19.1.6+st.8/bin/starm-clang.exeto settings.json by default, but this is not enough for C++ files.Unless you also add--query-driver=${env:CUBE_BUNDLE_PATH}/st-arm-clang/19.1.6+st.8/bin/starm-clang++.exeC++ IntelliSense will be broken (red squiggles, no symbols, etc).Same issue for GCC toolchain: you need both gcc and g++ in the driver list.2. --multi-lib-config triggers errors in clangdIf you enable --multi-lib-config, clangd just starts throwing errors about missing headers and stuff, even though the project still compiles fine.Is this a known issue? Anyone have a workaround?By the way, is there any official way to download the standalone ST Arm Clang toolchain (without the VSCode extension)?It would be super u

Hi everyone,I'm working with an STM32F103C8T6. Even though I haven't programmed any code onto it myself, when I connect with STM32CubeProgrammer, the Registers panel immediately shows “SLEEP” (while on other ST boards it would show “HALTED”). Because of this, I can't perform a Full Chip Erase — the option appears but doesn't work.Here’s what I’ve tried:Connected only SWDIO, SWCLK, GND, and 3.3 V (no NRST).CubeProgrammer shows “SLEEP,” and erase fails.On other boards, “Connect under reset” works fine and allows erasing.Possible issues I suspect:No NRST pin connection → ST-Link can’t halt the MCU before it runs.Option Bytes might have RDP (Read-Out Protection) enabled.BOOT0 pin wrongly tied (stuck in System Memory mode).Some factory test code or previous user code (making MCU go to sleep on reset).What I tried from forum suggestions:Tried “Connect under reset” with NRST — this works on other boards but seems not to work here yet.Any ideas how to force-erase or regain access?I’d appreciat

I am using NucleoF446RE (STM32F446RE) with CubeIDE 1.19.0.I wish to set PLL  as 16MHz by HSE (STLINK 8MHz MCO).Because HSI clock is 16MHz.I had set PLL M/N/P = 4/64/8. CubeMX reported P was fail . ]So I had set P=4. and It makes PLL-CLK = 32MHzAfter hal generation I have modified SystemClock_Config as following. void SystemClock_Config(void){RCC_OscInitTypeDef RCC_OscInitStruct = {0};RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; /** Configure the main internal regulator output voltage*/__HAL_RCC_PWR_CLK_ENABLE();__HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE3); /** Initializes the RCC Oscillators according to the specified parameters* in the RCC_OscInitTypeDef structure.*/RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE;RCC_OscInitStruct.HSEState = RCC_HSE_BYPASS;RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE;RCC_OscInitStruct.PLL.PLLM = 4;RCC_OscInitStruct.PLL.PLLN = 64;RCC_OscInitStruct.PLL.

I work in a workspace but I use vim with clangd for editing my code. I am wondering if it is possible to create a compile_commands.json file and if so how. If the IDE uses cmake under the hood then it should be rather straightforward but I cannot understand how to proceed. see e.g. this:https://cmake.org/cmake/help/latest/variable/CMAKE_EXPORT_COMPILE_COMMANDS.html 

Hello，         After I use STM32CUBEIDE's built-in STM32CUBEMX to generate code, the source files and header files under the folder I created myself disappeared, how can this be solved?        Before I use STM32CUBEIDE's built-in STM32CUBEMX to generate code：      After I use STM32CUBEIDE's built-in STM32CUBEMX to generate code,all the files I created disappeared.     The compilation path of the file I created has already been saved, and I also checked the keep user code when re-generating option

I spent the time to learn how to get it up and running so that you don't have to. What I am explaining here was done on Win 10. My CubeIDE version was 1.6.1.Downloading and copying the files:At the time I installed it, STM32Cube_FW_H7_V1.9.0 was current. I downloaded it from here.After extracting the zip file, open a File Explorer window and go to the directory "<extractedFiles>\en.stm32cubeh7_v1-9-0_v1.9.0\STM32Cube_FW_H7_V1.9.0\Drivers\CMSIS\DSP"In the above directory, you will notice two folders: "Include" and "Lib". These two folders will have to be copied in your already existing project as explained next.Open another File Explorer window and go to the root directory of your project "<user>\STM32CubeIDE\<workspace>\<projectName>\Drivers\CMSIS". Here you need to create a new folder called "DSP". Once created, copy the to folders "Include" and "Lib" under folder "DSP".Unless your CubeIDE is already open, start it up. Unless the DSP folder isn't already visibl

Dear all, I am using Nucleo-F446RE and also Nucleo-F103RB.As you may know precise clock testing require for some application.For testing purpose always change RCC as Bypass HSE clock from STLINK on this case.Recently I have used Nucleo-F446RE as above but behavior is different as failure on startup.I have tried simple test on both Nucleo-F103RB and Nucleo-F446RE.F103RB's result is correct. Bypass clock is worked.I had reflashed STLINK side as latest build on both unit.So STLINK side has no delta. Using environment CubeIDE 1.19.0 with included CubeMX.Now I am looking F446RE SystemClock_Config in detail.

Hello, While I was developing code for STM32N6, which uses FreeRTOS that uses SysTick as tick source, I changed the HAL timebase to utilize Timer 6 (TIM6). I've noticed that the generated CubeMX code will incorrectly calculate the input clock frequency for the timer, by assuming it is APB1. According to the reference manual (RM0486 Rev 2, p.449), the kernel clock for the Timer 6 is the timer group 1 clock, which is derived from the SYS Clock, divided by the value of the prescaler TIMPRE. So it is not APB1, but it is SYSCLK/TIMPRE, if I am not misunderstanding something.What happened to me is that I had the TIMPRE set to '/2', but there was no code generated for setting TIMPRE, and the Timer was running from SYSCLK / 1, which was 400 MHz in my case. The CubeMX generated code used the value of APB1 (which was 200 MHz in my case) for the calculations and ended up with 2x greater frequency of TIM6 (period of 0.5 ms, instead of the wanted 1 ms).Here is the CubeMX generated code for HAL

Hi,I am trying to read peripheral registers on the H523 using STM32_Programmer_CLI.CLI parameters : -c port=SWD -r32 0x42020800 52Result:0x42020800 : FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF0x42020810 : FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF0x42020820 : FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF0x42020830 : FFFFFFFF It looks like it only reads the value from 0x42020800 (the first word).It works fine on the F103 so i am guessing it has to do with the protection on the H523.The option byte is ED (open). What can I do to make it work? KetilO

Hello, I am using the SWV viewer successfully to output messages from the microcontroller at runtime. This is a nice tool and usually it works fine.  When I run an application for a longer time (e.g. over night) I get this errorI did consider the trace buffer as a buffer like outputting to a UART. What is happening there?regards Alexander

Hi everyone,when I export a project from STM32CubeMX (6.1.1) to the STM32CubeIDE (1.5.1), a project with double space indent is created. However, the CubeIDE uses Tabs. How can I fix that? Who uses double space indent anyway?Thanks a lot :)

This warning is occurring in the STM32U5xx HAL driver's low-level ADC header file (stm32u5xx_ll_adc.h). The warning indicates there's a self-assignment of a variable analog_wd_monit_channels where a variable is being assigned to itself. STM32CubeMX/Target_1/STM32CubeMX/Drivers/STM32U5xx_HAL_Driver/Inc/stm32u5xx_ll_adc.h:6920:34: warning: explicitly assigning value of variable of type 'uint32_t' (aka 'unsigned int') to itself [-Wself-assign]6920 | analog_wd_monit_channels = analog_wd_monit_channels;| ~~~~~~~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~~~~~~~~1 warning generated.

I purchased a NUCLEO-U575ZI-Q and I noticed when I create a new project using the board selector and then create a new project with the MCU selector, I get different results in the IOC files which I think are causing me issues.This is the NUCLEO IOC:This is the MCU IOC:As you can see, Pin 36 is different between the two IOC's.  Obviously PA2 and PA3 are different interrupts.  I have my CC1101 connected to Pin 36.The datasheet shows Pin 36 as PA3. The code that is being generated for the MCU IOC is assigning Pin 36 to PA2:#define MCU_RF_GDO0_INT_Pin GPIO_PIN_2 #define MCU_RF_GDO0_INT_GPIO_Port GPIOA The code being generated for the NUCLEO IOC seems to match the datasheet: #define MCU_RF_GDO0_INT_Pin GPIO_PIN_3 #define MCU_RF_GDO0_INT_GPIO_Port GPIOA In the MCU IOC generated project, I don't get an interrupt. Both IOC's are using the same firmware version, STM32Cube FW_U5 V1.8.0. STM32CubeMX v6.15.0 shows the same results.Is there a way to fix this?Kindest r

Hi all,I keep running into a circular include problem in STM32 CubeMX projects:main.h is auto-generated and contains pins and peripheral handles.main.c must include main.h (CubeMX forces it).User modules (i2c_user, adc_user, etc.) need access to pins/handles, but including main.h in them causes circular dependencies.Workarounds I’ve tried:Creating a board.h wrapper — but CubeMX regenerates main.h, so it requires constant manual updates.Passing handles/pins as function arguments — clean but cumbersome.Including user modules only in main.c — works, but feels messy and unclear.  My question: How do you handle this in real-world CubeMX projects? Is there a clean pattern that survives main.h regeneration and avoids circular includes? Sorry if this is not the perfect section of the forum, but I believe this topic is quite relevant due to the challenging architecture of the generator.Thanks!

Hi everyone,STM32CubeIDE v 1.19.0MCU: stm32h755I am debugging correctly the dueal core by means i see all registers in the live expression changing values without my intervention as expected by the simple code i wrote. As soon as i input a value, let's say I change the value of a variable from 0 to 1, then the panel shows:I used to work with the 1.13.2 version and older fw package and never had this issue, with the very same MCU, but with the new fw package and new IDE this is what i get.I must say that to make it work in the first place I had to force the gcc toolchain using the command "gcc -gdwarf-4" in project settings. There is for sure a link but i can't get the hang of it.Thanks in advance to all. For the sake of understanding, i setup the debug config as explained in stm AN:https://www.st.com/resource/en/application_note/dm00629855-getting-started-with-projects-based-on-dualcore-stm32h7-microcontrollers-in-stm32cubeide-stmicroelectronics.pdf

Hello everyone.Why does the behavior of the while loop I wrote differ from the one generated by STM32CubeMX? Since the code generated by STM32CubeMX is highly abstracted, is it possible that even the same while loop behaves differently due to internal processing? Where can I learn about such rules? I'm a beginner, so I would really appreciate any guidance. If anyone knows, I would be grateful for your help. Here are the details of the issue. 1. When code is written inside the while loop generated by STM32CubeIDECode:Result: It doesn't work correctly. It seems that something inside the while loop isn't functioning properly.2. When code is written inside the while loop wrote by myself.Code: Result: It works correctly     

I'm trying the program an STM32G0B1RET with the STM32CubeProgrammer. It seems the programmer sends a 0x7f and the MCU responds, but maybe too late to connect?
