1. Limitations

ID	Summary
Authentication issue	If you have encountered an authentication problem while using STM32CubeIDE, don't worry. You simply need to set your connection parameters. For more details see link below: https://community.st.com/t5/stm32-mcus/how-to-set-the-network-connection-parameters-for-stm32cubeide/ta-p/585694
133183	Unable to debug using FreeRTOS aware with a J-LINK Ultra+ in STM32CubeIDE 1.10.1
138771	To start debugging in the NS zone when the product status is TZ-Closed for the STM32H5 using ST-Link GDBServer, add the following script to "Run Commands" in the debugging configuration. set breakpoint always-inserted on tbreak Reset_Handler monitor reset set breakpoint always-inserted off si For the "Reset & Restart" button to work: - Add the same script - Select "None" as the type.
143485	Post build commands are restored by using one of the following two options : restore the post-build command by applying a "code generation" change the default behavior of the command "restore Defaults".
146043	On STM32H745 Cortex-M4 Dual Core projects the pre-defined breakpoint is maintained but not caught upon run
152549	From GCC11, the build can be in error with some functions: _close, fstat, _getpid, _isatty, _kill, _lseek, _open, _read, _write, _gettimeofday It’s due to that a state is define using the system information. The application needs to define a way to track time.
156539	If the user needs to set a proxy to be authenticated, a check for connection should be done: Windows > Preferences > STM32Cube > Firmware Updater and then Check Connection.
166245	When using the STM32CubeMP13 bare-metal firmware and activating Azure® RTOS ThreadX, the STM32CubeIDE linker file must contain the following section to avoid compilation issues: .stack : { _stack_bottom = ABSOLUTE(.); /* Allocate room for stack. This must be big enough for the IRQ, FIQ, and SYS stack if nested interrupts are enabled.*/ . = ALIGN(8); . += 32768; _sp = . - 16; _stack_top = ABSOLUTE(.); } >RAM _end = .;
171852	The implemented toolchain is allocating to an enum type only as many bytes as it needs for the declared range of possible values.
174727	STM32CubeIDE cannot make the project build automatically after having changed the IP configuration, it cannot automatically control this configuration, the user needs to increase Flash size manually when needed depending on his configuration.
189888	For STM32WB05 et STM32WB09 devices the connection Under Reset type is not supported
192219	For cortex M55 (like STM32N6), GCC12 and earlier versions detect warning using OFast and O3 optimizations level. Workaround: Install and build with GCC13 available through update site mechanism. Compile without MVE extension, which can be done by passing argument "-mcpu=cortex-m55+nomve", in Settings > GCC compiler > Miscellaneous
198955	STM32WB0x and STM32WBA5x products: Starting from Example Selector: After importing an STM32Cube wireless applications (BLE, Thread / Zigbee, …), user will get issues during project compilation Workaround: To resolve this issue, users are advised to regenerate the project. Staring by import: After importing an STM32Cube wireless applications (BLE, Thread / Zigbee, …) of the STM32WB0x products using the menu “File -> Import -> Import Existing STM32CubeMX Configuration File (.ioc)”, or “File -> New -> STM32 Project from an Existing STM32CubeMX Configuration File (.ioc), users will get issues during project compilation. Workaround: To resolve this issue, users are advised to follow these steps: In the project structure, right click on “Common” folder located under “Projects” folder Go under “Properties -> C/C++ Build -> Settings” Uncheck the “Exclude resource from build” checkbox Click "Apply and Close" then retry the project build.

3. Known issues

The known issues are split into general, STM32CubeCLT, OS-specific, and target-specific issues.

3.1. General issues

ID	Summary
59435	Having a space or non-ASCII character in the project/workspace path or installation path is not fully supported.
63624	Some STM32CubeMX pop-up dialogs are not opened in front of the STM32CubeIDE workbench on all OS's.
68184	Hierarchical projects cannot be imported with the option Copy into workspace.
68440	Hierarchical projects cannot be renamed.
89454	Restart configuration only works for flash memory projects and not for RAM projects. Program Counter register is not set correctly. Manual work-around: In Restart configuration, manually set PC to the ResetHandler() in RAM: set $pc = 0x20000xxx.
115928	Editing live expressions while target is running does not work with SEGGER J-Link.
124062- 152549	GCC-10 is more strict with respect to declaration of global variables in header files. Read the GCC-10 porting guide, so many warnings and errors result.
133183	STM32CubeIDE cannot debug using FreeRTOS aware with J-LINK. Work-arounds, if: Reset strategy == Connect under reset, requires Initialization commands: info threads info threads thread 2 Work-arounds, if: Reset strategy == None (attach mode), requires Initialization commands: info threads info threads thread 2 stepi
139637	Creating new STM32Cube project inside STM32CubeIDE is not possible if ioc-editor is point at STM32CubeMX stand-alone
156812	Missing string table in Build Analyzer while showing the bytes of the size of the ".rodata" section .
159507	Issues detected when updating STM32CubeIDE version from 1.9.0 to 1.13.1.
162500	After programming a device in Run mode, STM32CubeIDE opens every time a new tab with startup file and give focus on that tab.
169316	When building an existing project, using GCC11 or GCC12, a warning should be noticed: “elf has a LOAD segment with RWX permissions”. This warning highlights a vulnerability, to correct it and secure the data section, we suggest to update the linker files: From this kind of section: .preinit_array: { …} >FLASH To: .preinit_array (READONLY): { …} >FLASH But it’s incompatible with GCC10 and earlier versions.
170279	Failure to compile embOS due to missing stack variable as a new section defining _stack_start__ and __stack_end__ in linker file need to be added in linker file once it is required by ThreadX.
183033	The restore default build configuration feature lost the build commands.
189478	On Ubuntu 22.04 while creating a new STM32 project, STM32CubeIDE stucks at MCU finder step. Issue can be avoided by starting STM32CubeIDE with "wayland" version, or start it with sudo mode.
199067	In STM32CubeIDE 1.17.0, Hex files are not generated, setting a post build command: arm-none-eabi-objcopy -O ihex "project_name.elf" "project_name.hex" is required.
197993	In STM32CubeIDE 1.17.0, MP2 sources are not installable following project import steps, instead all update source need to be deactivated expect OpenSTLinux source first.
200233	Compilation error when using toolchain GCC 12.3 with CubeIDE 1.14.1. As Workaround, I proposed to the customer to download GCC12 and load it from local by setting the toolchain Name: GCC12 Prefix: arm-none-eabi- Location: C:\ST\STM32CubeIDE_XXX\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.12.3.rel1.win32_xxx\tools\bin

165338- 189478	Using Ubunto 22, the target selection doesn’t appear normally without sudo permission. Workaround: start with sudo permission or start the wayland binary instead of STM32CubeIDE binary.
175176	Using the generic Linux installer, the libncurses must be installed independently.

3.3. Target-specific issues

3.3.1. STM32G4

ID	Summary
194756	Problem with project creation using STM32G411 with the 1.6.0 firmware. Workaround: use the version 1.6.1 of the firmware.

3.3.2. STM32H7

ID	Summary
73552	Serial Wire Viewer configuration is not reset for STM32H7 devices on the next launch if it was terminated with record active when using ST-LINK GDB server.
79658	ST-LINK GDB server reports being suspended on address: 0x05F0001 when debugging STM32H7 dual-core devices and the core under debug goes to sleep.

175966	H7RS project on Ubuntu with ExtMemLoader context configured: Postbuild commands cannot be passed successfully when STM32CubeIDE is installed with sudo. Workarounds: Installing STM32CubeIDE on Ubuntu but without sudo. (add execute permission to the installer then install it without sudo permissions). If STM32CubeIDE was installed with sudo permission, postbuild command needs to be performed manually by passing the sudo permission first in command line.
202605	For the STM32H7Rx/7Sx microcontrollers in the STM32H7 series and when activating TRACER_EMB, the NONCACHEABLE region size in the linker file need to be increased to fit TRACER buffer. To add into the section: __RAM_NONCACHEABLEBUFFER_SIZE = 0x400;

3.3.3. STM32MP1

ID	Summary
73895	Debugging in production mode requires a network connection. If STM32CubeIDE is configured to use a network proxy, then the IP address of the STM32MP1 board needs to be added to the "Proxy bypass" list.
