You should tell the BDI to initialize the SYPCR register, otherwise the
internal watchdog timer will keep resetting the CPU.
[INIT]
; *** Initialize the core internal registers
; Program the SYPCR - Disable the watchdog timer
WM32 0xf0010004 0xffff2081
You will need to initiliaze other internal registers as well (BCR, SIUMCR,
BRx, ORx, ...).
I'm not sure if this will be enough to solve your problem, but it should at
least be a start.
