FreeRTOS & ColdFire v4 core

Posted by Alessandro on August 31, 2012
Hello,
I'd like to know if the FreeRTOS port for ColdFire v2 works also for a v4 core.

Thank you
Alessandro

Sorry - I don't know.

If the V2 core is a subset of the V4 then you might need to add things to the context that is saved and restored (floating point?). If the cores are the same, but the V4 adds things like an MMU, then you would have to ensure those extra things were handled or switched off.

Note that the "known issues" list notes the the current CodeWarrior V2 port is out of date due to changes in the way the compiler uses the stack. A fix is posted but not integrated into the main line code.

Regards.
