imx233 keeps rebooting while initializing power.

I'm working on my own imx233 board and I get unexpexted boot problem. Using bootlets the board keeps rebooting just after voltage measurement.

 

I double checked every power pin, and the inductor.(Since I did not intend to use battery I did not put any capacitor connected to DCDC_Batt and Batt, could this be a problem?)

 

I tried with u-boot, and it also crash after "HTLC", but does not reboot after. The voltage are then stable 5V, 4.2V, 2.5V are ok, but 3.3 VDDA VDDD are down to zero.

 

Would you have a hint on where to look for ?

 

Thanks in advance.
