Working on IAR ColdFire port I realized Code warrior port which I used as a start point doesn’t save EMAC registers in context switching macros. I think it should be fixed.

I’m not sure it would make sense to save the EMAC registers. There is only one EMAC peripheral and that will be having a conversation that cannot be interrupted.

EMAC is not a peripheral but a core unit. As I understand (may be not right ) all emac commands are atomic and its state and registers should be stored with context. I will rise this question on freescale tech support to clarify.

I have checked FreeScale MQX dispatch source code. They save/restore EMAC.

In which case, apologies, I was thinking “media access controller” rather than “multiply accumulate”.

Yes, It is a confusing acronym they used.
Should I submit a bug to the tracker? I can make new portasm.s
