error at startup running Hello World Example in rtems 4.6.6 / erc32 bsp

[Andrei Chichak]

Holy cow, just this morning I'm bringing up a new BSP in RTEMS 4.9 for  
a Coldfire 5282 and I am currently trying to cure this exact same  
problem.

Mine looks like the problem happens in a routine called  
_Workspace_Handler_initialization. No further information yet, I'm  
trying to single step it.
