ColdFire CW port EMAC registers missedPosted by Dmitri Snejko on January 9, 2010 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. Regards, Dmitri. RE: ColdFire CW port EMAC registers missedPosted by Richard on January 9, 2010 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. Regards. RE: ColdFire CW port EMAC registers missedPosted by Dmitri Snejko on January 10, 2010 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. Regards. RE: ColdFire CW port EMAC registers missedPosted by Dmitri Snejko on January 10, 2010 I have checked FreeScale MQX dispatch source code. They save/restore EMAC. Regards. RE: ColdFire CW port EMAC registers missedPosted by Richard on January 10, 2010 In which case, apologies, I was thinking "media access controller" rather than "multiply accumulate". Regards. RE: ColdFire CW port EMAC registers missedPosted by Dmitri Snejko on January 10, 2010 Yes, It is a confusing acronym they used. Should I submit a bug to the tracker? I can make new portasm.s Regards.
