As far as I know, none of the core developers had any micaz motes with the new chip to test the 2.1 release, therefore this fix was not incorporated into the micaz code. However the iris mote does have this new chip, and the iris driver (tos/platforms/iris/chips/at45db) does in fact work as described in the above posts. > 2) I just have 4KB of RAM on atmega128, but after adding external > FLASH, will I be able to test DELUGE, or do we need a bigger RAM to run the > program initially.
