Constant at a defined address

Constant at a defined address

[Phildale]

In other compilers this works

#define Address

const u8 Var[] @ Address = {
    1,2,3
}

so Var is alway at address, how can i do this with teh GCC compiler?

thanks

You can't.

You can do something along these lines using the linker.  Read about
linker scripts in the linker manual.

thanks i did it like this

const u8 ConfigArray[] __attribute__ ((section ("ConfigArea"))) = {

}

then used the linker to place the section ConfigArea.
