Hello Hector,
thank you for your quick reply.

It is from phytec: http://www.phytec.com/pdf/manuals/L-667e.pdf and luckily we have also
boards with 32MByte Flash, would this be enough? The board has also a MMC card slot (but it is not working in uboot)
or for demo purpose I could also boot via tftp.

So you mean to be in sync it is better to use sid than lenny? Wouldn't be a problem as I could just install debian sid on another partition.

I did this but i get the same error when using emsetup:
debian:~# dpkg-reconfigure dpkg-cross
debian:~# emsetup
Error: dpkg-cross does not currently support "arm"
debian:~#

So I guess arm should be ok for the XScale PXA270.

If I can make a little demo running I will make a "how to" document on a basic level (a step by step) anyway for the customer. Don't know if such a doc would be interested for you guys.
>> Any help is greatly appreciated as I am stuck right now.

It is not so much I want, just a little emdebian demo ;-).
