i.MX233 Board not powering up

Hello

 

I have a custom board designed based on the i.MX23 CPU. I am powered from 5V DC without the Battery input, I am unable to powering up

VDDXTAL has 1V, crystal is oscillating at 24Mhz but the DCDC converter is not turning on and also Linregs (VDDIO, VDDA, VDDD, VDDMEM)

I am using the reference design i.MX23 Reference schematic rev C

 

I need to burn some bit to power up?

How can I debug the startup process?

 

Thanks for any advise
