[avr-gcc-list] Variables in external SRAM

[Peter]

Hi,
i have an external device that i can treat a sram, and i want to write to
it via a variable. But my compiler complains when i try something like
this: 
char test;
&test = 0xFFFF;

i know i can do
*(char*)(0xFFFF) = 0xAB;
but i want to write to a variable.
I'm not good in programming  c code, but the code above means
"value of the char pointer with the address 0xFFFF", is this right?

Thank you, Peter Holtermann
