Hi Ole,

Do you really think, that using an 8 bit NAND Flash would make that much 
difference? I know that you had bad experience with the slow NOR Flash 
access on Ethernut 3, but it's a big difference between reading data 
from an 8 bit device or running code in an 8 bit device.

The problem with large 16 bit chips is, that there are only a few types 
available in the Gigabit range and the availability may cause problems. 
And no, there is definitely no more space available for a second one. 
The board is fully packed on both sides.

Harald
