Re: avrxmega7 device-not-found

Did you try 
-mmcu=avrxmega6


avrxmega6 
“XMEGA” devices with more than 128 KiB of program memory. 
mcu = atxmega128a3, atxmega128a3u, atxmega128b1, atxmega128b3, atxmega128c3, atxmega128d3, atxmega128d4, atxmega192a3, atxmega192a3u, atxmega192c3, atxmega192d3, atxmega256a3, atxmega256a3b, atxmega256a3bu, atxmega256a3u, atxmega256c3, atxmega256d3, atxmega384c3, atxmega384d3. 

avrxmega7 
“XMEGA” devices with more than 128 KiB of program memory and more than 64 KiB of RAM. 
mcu = atxmega128a1, atxmega128a1u, atxmega128a4u.

  The avr libc user manual shows that part under supported devices. Have you tried it?

    Senthil,


    (I am just a newest newbie, but,) Assuming your hypothesis is correct, what should I pass to compile the code on http://www.atmel.com/tools/XMEGA-A3BUXPLAINED.aspx, using Atmel ATxmega256A3BU microcontroller?
