FreeRTOS runs on some CPU that use MMU already but it does not make much use of MMU.&nbsp;

What do you want to do with MMU?&nbsp;  
Which processor are you using?

I just want to run FreeRTOS and webserver .  
My processor is ST SPEAr HEAD 200 , which used ARM 926EJ-S with MMU.

I think if the MMU is not used for any purpose by anything else in your system then you can basically ignore it.&nbsp; Please don’t just take my word for it though, try it out.
