[U-Boot] Problems booting without BDI

Hi all,

I made a port of u-boot for my board, with MPC8343.

The problem is that when i run u-boot with the BDI2000 (using "reset run"
command), u-boot loads normally, but when i take off the BDI nothing
appears on serial.

BDI is setting the reset configuration word, and is the same word found
in u-boot image. I commented the line wich BDI sets the reset word, and
tried to read it from the BDI, its seems ok _BUT_, nothing appears on serial.

Any ideas about what could be happening?

Here is the reset configuration word that BDI and U-Boot are using:

BDI:
====

RCW   0xA0602000 0x04030000
