I have had the same issue.  You need lines similar to the following
in your bdi config file to stop the watchdog timer.  Then you will
need other lines to set various registers to match your hardware
bus widths, etc.

[INIT]
; init core register
WREG    MSR             0x00001042      ;MSR  : ME,RI, exceptions high
WM32    0x000101a8 0xf0000000 ;move internal space 
WM32 0xf0010004 0xFFFFFFC1 ;SYPCR: disable watchdog
