Java error when enabling X-CUBE-FREERTOS on STM32U5

[grumblyturtle]

6.11.1 with STM32U575RITx

when I click "CMSIS RTOS2" to enable the installed middleware X-CUBE-FREERTOS, mouse shows a busy icon and the FreeRTOS configuration in the bottom panel never opens.

STM32CubeIDE can open the IOC file and the FreeRTOS configuration panel is displayed there fine.

Hi @grumblyturtle ,

Before Selecting the FreeRTOS™ version and heap model at CMSIS RTOS2, make sure that X-CUBE-FreeRTOS is added properly.

You need to:

1. click [Select Components] under the [Software Packs] menu.
2. Scroll down the list and select [STMicroelectronics.X-CUBE-FREERTOS]. In case it is not installed or you would need to use a different version, install it first using the [Install] button within the [Selection] column.

Try this way and let me know if you still have the java issue or not.

Thanks for the reply, obviously the module is installed, otherwise I would not even see the checkbox to enable it.

Clicking the CMSIS RTOS2 checkbox produces the described freeze and errors in the log.

What About the Heap? Make sure that required selections are done:

I think opening the IOC file in STM32 Cube IDE fixed the problem, somehow.

The RTOS tab now works normally in Cube MX.

also yes everything is installed.

Glad to know that your problem is fixed. Have a nice day @grumblyturtle.
