previously i was working atmel studio 6 with asf of 2.11.1, then i switched to atmel studio6 service pack-2. This has been done successfully.
i am working on standard i/o application in evk1100 board. so i tried to change ASF version of solution from 2.11.1 to 3.5.0 through project properties, but it did not change then again come older version. How can i change the asf version of solution.
