STM32CubeIDE. X-CUBE-FREERTOS. Can't add/edit tasks, queues, timers, semaphores, mutexes, etc.

Periodically, the Add buttons in the configurator stop working and it is impossible to change values in tasks, queues, etc. The system does not respond to mouse clicks (the editor window does not appear). However, the Delete button works. Restarting the IDE helps. It works in other configurators (GPIO, NVIC, Definition Creation).

Hello @ATret.3 

 

STM32CubeIDE 2.0 is now independent from STM32CubeMX. With this release, device configuration, previously handled within STM32CubeIDE via STM32CubeMX, is now exclusively available through the

stand-alone STM32CubeMX tool.

Users will configure microcontroller peripherals and generate initialization code separately in STM32CubeMX, then import the generated projects into STM32CubeIDE for coding and debugging.  

STM32CubeIDE, is now a stand-alone tool, offers the possibility to create empty project through its own MCU/Board selectors now present inside.

You can get STM32CubeIDE 2.0 through this Link .

 

Thanks.

Mahmoud

Hello @ATret.3 

 

Let me thank you for posting.

Hello @ATret.3 ,

 

I created a project from scratch with STM32U083RCTx, and the behavior described was not reproduced  

with STM32CubeMX Standalone and MX integrated in IDE.

For more investigation, could you please provide your Ioc.File.

 

Thanks.

Mahmoud

Hello, @Mahmoud Ben Romdhane 

I only encounter this problem in STM32CubeIDE. It doesn't happen right away, but after 2-3 compilation/debugging cycles. Everything works fine in CubeMX. Now I've switched to working in parallel with a separate CubeMX for editing the ioc file and generating code, and CubeIDE for working with code and debugging.

I am not ready to provide my ioc file yet. I will try to make minimal builds and provide the file and results.
