Dear all,I am using an application on the NUCLEO-F401RE board. I wrote and successfully compiled a program (with no errors), but I am encountering an error during debugging with the message: "Failed to execute MI command: remote target localhost:61234".The ST-LINK (ST-LINK GDB server) is configured as the debug probe and SWD interface.I have replaced the communication cables and reinstalled the STM32CubeIDE software. It used to work normally.The log is attached below:

Editor hover no longer works on my STM32CubeIDE installation, and I have no idea why.Hover setup is like this, which I believe should be correct. Also, I haven’t changed anything (first time seeing this menu myself).I haven’t found a menu or anything that turns the hover feature off. Does anyone have an idea what the problem could be?When a feature is not longer working or available, I really find out how often I use it… Edit: Version is 2.2.0. Now checking for updates… Nope, no updates.

I need to view all Cortex-M7 debug and trace/debug subsystem registers during debugging—similar to how peripherals like DAV, RCC, and GPIO are displayed—but they do not appear in the SFRs list; specifically, I need to view the ITM, ETM, WDT, and SWO registers. 

Hi what is the crrent state of agentic programming with cub ide? Like I want Claude code to add an EMMC driver to my existing project. Is this possible? 

Hi, Good DayI am Mike, I work for Lenovo Japan, I am currently doing a POC for ML enabled embedded application using STM32N6570-DK. I just got stuck after debugging incremental update to my firmware (add ThreadX). Background / PretextWith the help of https://community.st.com/stm32cubeide-mcus-28/stm32n6570-dk-debug-keeps-failing-error-32-load-failed-not-sure-if-i-should-debug-fsbl-or-appli-168613?tid=168613&fid=28, and STMicro Template_Isolation_XIP project, I was able to setup a project that runs debug from FBLS to AppS to AppNS. I plan to build my target firmware bit by bit, and so I was able to add UART1 for debug log and it was working at that point.My next step was to add ThreadX, so I configured .ioc to add ThreadX and TIM6 as source clock to SYS_NS, then I forgot to turn on the RTOS awareness to ThreadX->CoreM55 and I begun to fail connecting when hitting debug.I kept a copy of basic Template_Isolation_XIP that was perfectly working, and event switching to that project, t

My pc at work reboots itself whenenver I want to search something in a project (Crtl+h searching). I had windows 10 upgraded to windows 11 and that happened in windows 10 and later in windows 11. I formatted the pc and installed windows 11 from scratch. It still happens. And now, whenever I try to compile it reboots the pc too.If I check windows event monitor I usually see error 6008 unexpected event. Also I usually see error 41. Pc is new (about 2 years) and this does not happen with System Workbench, Visual studio or other eclipse ides I have in the same machine. Have you experienced this?

I started a debug session on Cube IDE (version : 2.2.0) for my STM32F303 Discovery board.I got curious about GDB and I discovered that when I start a debug session, two GDB clients listening to the same GDB server are created. Why does it start two GDB clients?Task Manager ScreenshotTCP Connections to the GDB Server PortOne other confusion, whenever I start a new GDB client that listens to same GDB server, the console in Cube IDE prints the message “Waiting for debugger connection”. But when I monitor its TCP connection, I can see that its two gdb clients did not disconnect. And when I halt or resume the program execution or send gdb commands via the debugger console like “info registers” for exemple, it works fine. (I start my own GDB client by running the arm-none-eabi-gdb.exe executable)Console’s Message when I Start a New GDB ClientAny idea why the console print this message whenever a new GDB client connects to the GDB server?

I am trying to download the windows version of the IDE but I can't get it to work. Either the download button doesn't do anything or it's just not there. I've tried with different email accounts, different web browsers, different networks but that didn't do it. I've looked on here and it was suggested to disable browser extensions like ad-blockers and such and I've disabled all of them and still nothing. I would appreciate any help.

Hi all,I'm stuck on debugging with the STM32N6570-DK and could use some help. I've spent a few days on it and I'm running out of ideas.My setup:- Board: STM32N6570-DK (Rev B, device ID 0x486)- STM32CubeIDE 2.2.0 (ST-LINK GDB server 7.14.0)- STM32CubeProgrammer 2.23.0- ST-LINK FW: V3J17M11- CubeN6 FW package V1.4.1- Project made in CubeMX with FSBL + Appli (Appli runs from external flash)- Boot switches set for dev boot (BOOT1 = 1)What's happening:Most of the time the debug session doesn't even start. I get:"Target unknown error 32Error in initializing ST-LINK device.Reason: Unknown. Please check power and cabling to target."Sometimes it does connect. When I launch the Appli debug config, it programs the Appli into external flash fine (I can see it erasing sectors and downloading), but then it stops with "Setup exceptions" and the core is sitting at 0x18003a1a (boot ROM area, no source).When I launch the FSBL debug config (with the Appli .elf added in the Startup tab), the GDB server co

I previously wrote the code for my project and generated the HEX file. I copied my project folder from the workspace_2.1.0 directory to a USB flash drive.Now, when I open this copied project on a new PC using STM32CubeIDE, I cannot find the page where the settings for generating the HEX file are configured.Could someone please help me?

I’ve been using STM32CubeIDE, STM32CubeMX, STM32CubeProgrammer, and STM32CubeMonitor on a Mac currently running macOS 26.6.When I run env or export in Terminal (which uses Zsh by default), I find these two STM32-related environment variables.STM32CubeMX_PATH=/Applications/STM32CubeMX.app/Contents/ResourcesSTM32_PRG_PATH=/Applications/STM32CubeProgrammer/STM32CubeProgrammer.app/Contents/Resources/binExamined Zsh dotfiles in my home folder and found the following two *export*s in ~/.zshrc that set them.export STM32CubeMX_PATH=/Applications/STM32CubeMX.app/Contents/Resourcesexport STM32_PRG_PATH=/Applications/STM32CubeProgrammer/STM32CubeProgrammer.app/Contents/Resources/binWhich apps have added these; CubeMX, CubeProg, or perhaps the respective plugins from CubeIDE?

Hello everyone,I am experiencing an issue with the FreeRTOS Kernel Awareness view in STM32CubeIDE, specifically regarding the task runtime statistics. The plugin seems to be failing to parse or display the correct runtime percentages, showing almost all tasks permanently stuck at 1% or <1%.My Setup & Recent Changes: MCU: STM32G474 IDE: STM32CubeIDE v2.2.0 Previous RTOS: FreeRTOS V10.3.1 (Generated via STM32CubeMX with the CMSIS-RTOS v2 wrapper) Current RTOS: FreeRTOS V11.3.0 (Added manually via the ARM software pack, bypassing CubeMX generation) The Problem: I recently migrated my project to native FreeRTOS V11.3.0. I removed the old CubeMX-generated middleware and integrated the new version using the ARM pack. I also configured everything required for runtime statistics to function properly (setting configGENERATE_RUN_TIME_STATS, configuring the hardware timer via portCONFIGURE_TIMER_FOR_RUN_TIME_STATS(), and setting up portGET_RUN_TIME_COUNTER_VALUE()).While the project

Hi, I have just installed STM32 Cube IDE 2.0.0 for Mac OS Apple Silicon, and then installed the GCC ARM for STM32 10.3-2021.10 toolchain through the toolchain manager. However when I import a project using this toolchain I get the nullgcc error.I also tried creating a new project and setting the toolchain to 10.3-2021.10 but still get the same error.When I look into the eclipse plugins folder searching for the toolchain binaries, I only see a .jar file but not the actual compiler folder with the binaries ls -l /Applications/STM32CubeIDE.app/Contents/Eclipse/plugins/ | grep gnu-tools-for-stm32Jul  9 11:22 com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.10.3-2021.10_1.2.100.202508251041.jarJun 26 11:52 com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.14.3.rel1.macosaarch64_1.0.0.202602081740un 26 11:52 com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.14.3.rel1_1.0.100.202601091506.jarJun 26 11:52 com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32_2.

From cube 1.3.0 I always get this error and the cause seems to be the path generation in .d files. In cube 1.12.1 the path is relative but from cube 1.3.0 it is absolute and generates something like \\?\C:\.... So the only solution for me is to stay with cube 1.12.0. The build however seems ok an the bin file is generated. Did anyone had a similar issue?

Hi,I am trying to debug STM32N6 program loaded in external flash. When I started the debugger in the FSBL project I can put a breakpoint just before it jumps into application inside external flash. It is obvious I wont be able to see the symbols since it is not loaded. So I loaded my application elf file under debug_configuration/Startup/Load Image and Symbols (See attached image). When I start my debugging session, I encounter the following error and was unable to debug even FSBL code.Board: STM32N6 DKSTM32CubeIDE: 1.17.0Platform: Windowproject: Template_XIP_FSBL (found under Stcube package for N6).Here is the error:STMicroelectronics ST-LINK GDB server.

Hello all,I can't download the STM32CubeIDE even as I am registered. There seems to be somthing broken with the Web page. I have tried several browsers. This is what I get, so there is no download button and the table is garbled:Any help appreciated.Johannes 

Hi! When trying to run the code in STM32CubeIDE (“Run as”) I see the error“No ST-LINK detected! Please connect ST-LINK and restart the debug session.”.In error log I also see the message“Cannot run program "/usr/local/bin/stlink-server" (in directory "/Users/<username>"): Exec failed, error: 86 (Bad CPU type in executable)”This started to happen after updating to MacOS 27.0 (Golden Gate) from version 26. Before that it was working fine.Also the board can be seen by STM32CubeProgrammer (see screenshot).Also I installed as a separate package ST-LINK-SERVER 2.1.1 (https://www.st.com/en/development-tools/st-link-server.html)Board: Nucleo-F446RELaptop: Apple M4 Pro with MacOS 27.0IDE: STM32CubeIDE Version: 2.2.0 Build 29186_20260626_0934 (UTC)
