AM1808 reference design

Hi,

      We are developing the device based on AM1808 and we are using OMAPL138 LCDK reference design. 

Is AM1808 have separate reference design or OMAP138 and AM1808 are same?

If its not same what are the changes need to be do in AM1808 schematic from the reference of OMAPl188 LCDK reference design?

Do we need to change in power section and boot section or any other sections? Kindly let me know the details.

Thanks

Sangly.
