RTEMS_malta board support

[CHINTHA MOL C.S.]

Hi all,

I would like to port RTEMS to malta mips evaluation board.
I successfully built RTEMS 4.10.99 with malta BSP.
I need to load the generated hello.ralf to malta board with YAMON
bootloader.

I edited the MIPS Malta linker script .
RAM base is changed from 0x80000000 to 0x800c0000. and section start from
0x80010000 to 0x80100000.

I converted the hello.ralf file to srec format using mips-retms4.11-objcopy
and successfully loaded it via tftp. But while running it, exception in TLB
occures. the error log is given below.

How can i successfully run this rtems-application (hello.ralf) in malta
board?
