A good starting point might be the at91sam7sek target. On Wed, Jun 4, 2008 at 2:42 PM, Huguenin Frédéric <Frederic.Huguenin@he-arc.ch> wrote: > Thanks I'm using the atmel.

For my hardware, I usually create such a cdl package. See the the ecoscentric documentation about SPI. I was just referring to the at91sam7sek target as an example on how to add the required SPI cdl packages to your target.
