Hi Harald,

Yes I know. Linux uses the device as a file system and thus the nand
flash also contains the program binaries etc. Normaly it will be
formated with a jffs2 filesystem.

So using a 8bit interface results in slower filesystem access and long
startup times for applications.

:) At least it won't be a show stopper to use a 8 bit device. But it
would be nicer to have a 16bit one. So if there's no chance, that's ok.
I'm shure there will came up more ethernut boards in the future, and
they also shall have options for small innovations.

Ole Reinhardt
