BDI and u-boot

Can anyone please give me advice on the following:
U-boot was burnt at 0xfff00000 (.TEXT) and starts successfully whenever I disconnect BDI2000 and power cycle our MPC8272ADS.
Without BDI it starts without any problems. But when I try to debug using BDI board keeps restarting:

8272>reset
- TARGET: processing user reset request
- BDI asserts HRESET
...
8272>info

     Target CPU        : MPC8280/8220/5200 (Zeppo)
     Target state      : debug mode
     Debug entry cause : instruction address breakpoint
     Current PC        : 0xfff00100
     Current CR        : 0x00000000
     Current MSR       : 0x00001002
     Current LR        : 0x00000000

8272>go
*** TARGET: reset detected, restarting target
- BDI asserts HRESET
...

Reset entry point is at offset 0x100 so in fact 'go' does "go 0xfff00100" from my understanding, but why is it keep resetting? No serial output produced.

The map file
.text 0xfff00000 0x2ec14
cpu/mpc8260/start.o(.text)
.text 0xfff00000 0x3560 cpu/mpc8260/start.o

                 0xfff001b0                _start_of_vectors
                 0xfff03178                init_8260_core
                 0xfff032ac                dcache_enable
                 0xfff03314                relocate_code
                 0xfff00000                _hrcw_table
                 0xfff0324c                icache_enable

...

What do I miss?

Thank you,
