PSWITCH left unconnected and DCDC issue

Hello all,

 

I use a IMX28 with an external +5V power supply. I don't have any battery connected.

So, can I leave PSWITCH unconnected or do I have to tie it to GND or other ?

 

Second question, since I don't use a battery, do I need to connect something to "Battery", "DCDC_BATT" and "VDD4P2" ?

 

I followed the schematic of the evaluation board and my shematic looks like that :

But "VBAT" is leave unconnected, so can I remove C1 to C10, R1 to R4, D1 and L1 ?

 

Many thanks
