Cortex-M4 FreeRTOS MPU configuration

I want to set the OCRAM memory non-cacheable. How can I do it? I suppose that I have to modify some values in core_cm4.h but I have no idea to do it.

Don’t even know which chip you are talking about, but even if I didn’t I don’t think this is a FreeRTOS question.
