[En-Nut-Discussion] Ethernut on Cortex M3 da Luminary Micro

[Dave Warren]

Paulo,

I also think the Luminary part looks to be in meny ways better than the 
SAM7X256. The PHY included is the best improvement.

However it will not be so easy, I think also the interrupt response has been 
changed in Cortex.

Regards

Dave Warren
