This is more of an AVR specific question, you should ask on an AVR 
specific forum.

For example: http://www.avrfreaks.net

See these two pages:

Need Help - const - ROM-Area

[Michael Daiss]

Hello,

I thought, that with the prefix "const" it would be located in the ROM-Area...
But in the map-File it is located in the data-area, means in the RAM...
What must I do to locate it in the ROM-Area?

Thank you for help!!!

AW: Need Help - const - ROM-Area

[Michael.Daiss]

Hello,

I thought, that with the prefix "const" for instance an integer would be fix
located in the ROM-Area...
But in the map-File it is located in the data-area, means in the RAM...
What must I do to locate values in the ROM-Area?

Thank you for help!!!
