STM32 MCUs Software development tools

Why, oh why have you separated IDE and MX such that .ioc files can no longer be opened in IDE?I cannot imagine any benefits and it makes the IDE significantly worse, such that I've felt compelled to revert to version 1.19.0 ( go to Help -> About STM32CubeIDE -> Installation Details -> Installation History -> select version -> Revert)I couldn't find any other means of feeding back my strong dislike of this change other than a post like this. I hope version 2.1.0 comes out soon and re-integrates MX and IDE!

Above image you can see in toolchain option STM32IDE is disable . also i am facimng issure i =n import examples which stm32 provided for reference . you can also refer my shared video.

Hello everyone,I am facing a flashing/debugging issue with the STEVAL-SPIN3202 Rev 3.1 board.Board:STEVAL-SPIN3202 Rev 3.1Software Used:STM32CubeIDESTM32CubeProgrammerProblem:While trying to flash or debug the board from STM32CubeIDE, I get the following error:"Failed to start GDB server""Error in initializing ST-LINK device""Failed to connect to device"Also, in STM32CubeProgrammer:Read data operation failsTarget connection sometimes not detectedAdditional Observations:ST-LINK USB is detected intermittentlyBoard LED becomes dim/slow ON sometimesReinstalled STM32CubeIDE and driversInstalled ST-LINK driversTried different USB cables and USB portsTried lower SWD frequencyTried Hot Plug modeTried BOOT0 method

I was running a project in STM32CubeIDE (1.19.0) with 4 Tasks and it ran fine. Now I wanted to add a fifth task and after adding it and the oly thing I had changed was the Name (Task05 instead of myTask05) I got an alert box when saving the .ioc file:I went with this into the FreeRTOS forum, but they say it's an STMicro issue. So I'm coming up with it here now.

I created simple project using STMCubeMX2 for MCU STM32C552. I configured the clock by choosing HSIS on System MUX.  When I compile and run generated code it ends in HardFault_Handler. When using PSIS option - the same result. HSISDiv3 clock works well. When I divide HSIS or PSIS clock by 2 on AHB prescaler it also works.   Any idea? Thank you  

So I'd been merrily using STM32CubeIDE all morning, doing the usual code-download-debug cycle with no problems at all.Then, after some code updates & successful build, it suddenly can't reach the GDB server: STMicroelectronics ST-LINK GDB server.

Hi!I have set up a project for the STM32H523RET6 using the following setup:CubeMX: 6.15.0STM32 vscode extension: 3.5.1The project is configured to use starm-clang and starm-clang++ and the STARM_PICOLIBC toolchainI have created a .cpp file () that i added to my build and updated my CMakeLists.txt with the following: # Setup compiler settings set(CMAKE_CXX_STANDARD 23) set(CMAKE_CXX_STANDARD_REQUIRED ON) set(CMAKE_CXX_EXTENSIONS ON) ... enable_language(C CXX ASM) ... # Add sources to executable target_sources(${CMAKE_PROJECT_NAME} PRIVATE Core/Src/myclass.cpp # Add user sources here ) When building the project, it compiles fine, but clangd reports the following problem: nsupported option '-mcpu=' for target 'x86_64-pc-windows-msvc'clang(drv_unsupported_opt_for_target) Unsupported option '-mfpu=

Hello,the STM32G474RBTx CubeMX Clock Configuration ADC1_2 and ADC3_4_5 are swapped - the ADC1_2 Mux is actually referring to the ADC3_4_5 Mux, at least when it comes to the subsequent divider options in the respective ADC configurations.Setting ADC12 Mux to PLLP with e.g. 48.57 MHz allows me to put ADC3_4_5 into ASYNC_DIV_1, whereas the ADC3_4_5 Clock Mux is set to SYSCLK with 170MHz. ADC12 cannot use ASYNC_DIV_1 or 2, even though they should be able to.It also happens the other way around.I am using CubeMX 6.17.0 with the G4 package version 1.6.3

I use STM32CubeIDE on Linux Ubuntu (and to a lesser extent on MacOS and Windows, but I don't recall having a problem on the last 2 operating systems). About once or twice a day, at random, several of the keys such as <backspace> and <enter> and <delete> stop working. All the alphabetical and number keys work as normal. If I switch to a different application all the keys are working, but when I switch back to Cube the problem continues.I solve the problem by saving my work, shutting and relaunching Cube. Is this a bug in the application?

Hello EveryoneI am using CubeMX 6.17.0 and Embedded Software Package STM32H5 1.6.0:Is there a control missing to setup "Trigger Output (TRGO) Parameters?  In comparison to e.g. Tim15:   

I'm using STM32CubeMX 6.17.0 with NUCLEO-U575ZI-Q, it generated the following code:/* Initialize COM1 port (115200, 8 bits (7-bit data + 1 stop bit), no parity */ BspCOMInit.BaudRate = 115200; BspCOMInit.WordLength = COM_WORDLENGTH_8B; BspCOMInit.StopBits = COM_STOPBITS_1; BspCOMInit.Parity = COM_PARITY_NONE; BspCOMInit.HwFlowCtl = COM_HWCONTROL_NONE;The comment is wrong, the UART has 8 bits of data instead of 7 bits.

STM32N6 Nucleo boardCubeMX V6.17.0CubeIDE V 2.2.1Hi,First of all, disclaimer: I don't know the toolset or the STM32N6 very well, so I'm trying to get up to speed. There are some really good tutorials posted here which have helped me greatly, but I can't find a really good description of how to debug a FSBL_RUNL application on the N6. Given that some of the initialisation is performed by the FSBL, I wanted to download both FSBL and Appli in a single debug session, set breakpoints in both and run through FSBL into Appli. I can do it, but it currently consists of a hack:When 'DEBUG' is defined, extern 'BOOTStatus_TypeDef JumpToApplication(void);' in my FSBL 'main()' and call it instead of 'BOOT_Application()'. It works as long as the Destination Address is set to base address 0x24000000 in CubeMX,  otherwise, the vector table address is incorrect (Not sure why the

Hello, I wrote a project maybe 2 weeks ago, at that time, everything was ok.  then i used stlink to download and debug the code yesterday, at first time, it worked ok, but later, i did download and debug again with stlink. it cannot work. the log as below.my setting as below:
