AM3352: DDR3 schematic design

Part Number:AM3352

Hi Champs,

We would like to confirm which is recommend design for around of DDR circuit.

These two circuit use difference register value .

Could you please which value is correct or both value is possible ?

And this VDDS_DDR pin use "PULL-UP". Datasheet didn't recommend "PULL-UP" Is this pin also better to use "PULL" UP ?

1) am335x General purpose EVM (am335x_schematic_rev1_6a.pdf) mentioned "10Kohm Pullup" for VDDS_DDR

2) tmdexice3359_schematic mentioned "1Kohm" Pull up for VDDS_DDR.
