Re: [avr-gcc-list] Allocation of large globals in external RAM

[Jason Kyle]

You need to add a modified linker script to your project directory, see the
card test program in my eAVR project for an example. The linker scripts are
in /usr/local/avr/ unless you used the --prefix= option when installing etc. 
http://avr.jpk.co.nz/eavr.eavr.html

The linker knows nothing of MCUCR, your code is correct to initialise it
before doing anything else.
