bootloader - VxWorks 6.6 on PowerPC Boot Sequence _sysInit() opcode bizarity -

for project working on,
running on powerpc mpc-8641d, vxworks6.6.

i need launch vip image vip project.
investigating boot sequence seems boot-loader is:
reading binary header of image,
copy binary image (without hdr) 0x100000
, jumps 0x100000 (where _sysinit()) located.

doing same thing boot-loader, cpu freeze @ address 0x100004h

reading content of 0x100000 revealed following dump:

48 44 01 fc   ba ad c0 de   00 00 00 00   00 00 00 00   00 00 00 00   00 00 00 00   00 00 00 00   00 00 00 00 ... ... 00 00 00 00   00 00 00 00   00 00 00 00   00 00 00 00 00 00 00 00   00 00 00 00   00 00 00 00   00 00 00 00 

well, 0x484401fc looks function prolog, but, 0xbaadc0de must joke!

how vip run calling address.
missing else?

0x484401fc b 0x4401fc, should branching 0x4401fc , never executing instruction @ 0x100004 (unless returns, branch doesn't set lr have return manually).
