Hello @gerhard ,
There is no .ioc working project for FreeRTOS.
There is a rich set of FreeRTOS applications useful for your case with STM32cube packages that use HAL library and configured for different toolchains: EWARM, MDK-ARM, SW4STM32.
Try to pick the one suitable for the device and board you are using and start from it:
- STM32Cube_FW_F4_V1.25.2\Projects\STM324xG_EVAL\Applications\FreeRTOS
- STM32Cube_FW_L4_V1.16.0\STM32Cube_FW_L4_V1.16.0\Projects\STM32L476G-EVAL\Applications\FreeRTOS
To start with STM32CubeMx, I advise you to refer to the "FreeRTOS" section in the UM1718 STM32CubeMx user Manual.
Have a look also to the UM1722 User manual about "Developing Applications on STM32Cube with RTOS", this will help you on FreeRTOS configuration.
Please mark my answer as the best by clicking the "Select as best" button if it helped you. This will help other users find this solution more quickly.
