AFter downloading the SAM E servicepack for atmel device I don't know how to add is to uVIsion. How?
What version of uVision?
Is this a download from Atmel? What instructions do they give? A "service" pack suggests it's something you run to update the supported processors against an installed version of uv4.
A "software" pack is something else in the uv5 context. http://www.keil.com/dd2/pack/
