[ECOS] eCos Code at address 0x000? (MPC8270)

[Tim Sohacki]

Hello,
 
On the MPC8270, it appears that eCos has some code running at (or near)
address 0. I suspect this is eCos specific because the first PPC
interrupt vector stub is at 0x100.  
 
What is this code?  It appears to be executed at runtime, because if it
is trampled, the target will crash. Is it a NULL pointer write detector?

 
Thanks,
Tim.
