I have been trying to get the USB to serial on AT91SAM7S-EK to work
using the 256 part but having no luck. Does anyone have source with this
working?

What is it - "256 part"?
The examples for usb you can find at
http://www.siwawi.arubi.uni-kl.de/avr_projects/arm...
You need projects with UART.
Write me if you will have problems with compiation

I have problems with compiling this examples.  I have imported the code 
in eclipse but get this error :

No rule to make target `../compil/SrcWinARM/Cstartup.S', needed by 
`../compil/SrcWinARM/Cstartup.o'.  Stop.

TIA

I know this is an old thread, but for future reference ATMEL has working 
USB to serial code on their web site.

I have tested it on the AT91SAM7S-EK with the AT921SAM7S256 chip. I 
compiled the code with arm-elf-gcc. I'm using Yagarto with Eclipse in 
Windows XP.

You can download the software for your board here:
http://www.atmel.com/dyn/products/tools_card.asp?t...

The filename within the archive will be something like:
\packages\usb-device-cdc-serial-project-at91sam7s-ek-gnu.zip

The documentation for the code is here:
http://www.atmel.com/dyn/products/tools_card.asp?t...

The "CDC driver implementation" is what you want to use for 
USB-to-serial.
