    Hello @dvescovi ,

    Yes, the latest H5 version 1.5 supports CMSIS RTOS V2. The RTOS2 folder, which contains all the necessary files, is included under the CMSIS directory within the Drivers folder of the latest Cube firmware package.

    Kind regards, 

    DHIF Khaled

    yea I finally found but had to copy the csis_os2.c file locally and build it as part of my project..

    I am using ThreadX (Azure RTOS)  .. It would be nice if there was a selection in CubeMX to add support for CMSIS RTOS V2 ... like they do with freertos.

    I am also confused by all this. For the H755, I can select Free RTOS v2 and even configure threads, queues, semaphores via the Cube IDE. None of this seems to be apparent for the H5.
