Hi Support team,

Is it possbile to use 3.3V to power the MPC5748G_REVD ? If yes, could you please tell me where to power?

I have tried to use 3.3v via "3V3_SR" Pin. But the board doesn't work properly. 

Also i tried to use 5v via "5v_SR" pin and the board works fine.

Yes, i'm trying to use external power supply instead of USB cable.

Why you don't power it over 12V barrel external power connector (in the schematic P6)? It is expected option if USB is not used.
