Is there currently Atmel SAMA5D3 processor support for FreeRTOS?  
I couldn’t find an official or contributed Port for this processor -  
do you know if there is one, or one being developed now?

If not, would another Atmel Port be sufficiently similar to work?

Thanks for your attention…

There is not a specific port to that device, but there are more generic Cortex-A ports that have official demos for Cortex-A9 parts. I believe they have been made to work on Cortex-A5 core’d chips too. IAR and ARM compilers are officially supported, GCC currently unofficially so.

Richard,  
why is the Cortex-A port not enabling MMU? According to that article “it is not using MMU”?  
I need accesses with different attributes, and no MMU limits my choices.  
tnx,  
ovi

FreeRTOS does not support virtual memory. What do you want to use the  
MMU for?
