Does MQX support Virtual memory?

[bluehacker]

I am now reading mqx sourcecode, and find MQX seems like don't support virtual memory for coldfire V4e(for example MCF54455)and powerpc MPU which have MMU. 

Another question:

when do task switch, is it need to do cache refresh?

thanks?

MQX does not support virtual memory.

Cache refresh in the scheduler- what do you mean by 'refresh' cache? Instruction cache can be only flushed (invalidated).

sorry, I mean just flush cache
