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… Regards, Declan Traill Senior Software Design Engineer Chemring Australia

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. Regards.

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?
