S32R274RRUEVB startup

Hi,

I just got my S32R274RRUEVB board from NXP.

There are 3 power supply terminals on this board, do I have to connect them all to power up this daughter board alone as I don't have the motherboard? they are:

5V_DC_R

3.3V_DC_R

1.25V_DC_R

From the schematic, it looks like 1.25V can be internally supplied thru 5V_DC_R, what about the 3.3V_SR_LDO? can I just supply a single 5V supply externally to power up the board to do some simple test?

Is there any user manual to start with?

 

Thanks!
