[Icc-avr] Memory Setup and Speed

[Richard]

The below works fine. Even better - if there are some variables that you do 
want in external mem, then just do something like

#pragma data:extmem_vars
char foo[1000];
int bar;
#pragma data:data

and in the Options->Target->"Other Options" box, add
         -bextmem_vars:0x1100
or whatever the address for the start of the external mem is.
