Unhandled exception while running samples

[durai]

Hi all,

CPU - MIPS R3000 core (LX4189)
RTEMS-4.6-pre5
When I run the ticker and hello sample applications in my board, I am
getting an Unhandled exception at the end of execution (ie, after executing
all statements in the Init() functions, it throws the exception).

------------------------  crash dump --------------------

The EPC shows 80200068, from the disassembly I can find  sys_exit is located
there.

80200068 <_sys_exit>:
80200068:       03ff000d        break   0x3ff
8020006c:       00000000       nop
80200070:       1000fffd        b       80200068 <_sys_exit>
80200074:       00000000        nop

Should I implent the handler for software break?
