I have no guesses but recommend using powerpc-rtems-objdump -da to find
out
what instruction is at 00041A10.  That would give a clue as to what
happened.

One thing I do see is that the linkcmds assumes 32M of RAM.  If this
doesn't
match your board, it could be accessing non-existent memory.

I haven't heard a report on this BSP in a long time.  Please keep us
posted.
