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?
