About TLB mapping

From: Hua Ji <hidden>

Hi, folks,

Advice needed.

I am writting my TLB mapping for 405GP 128M physical memory.
When I try to assemble my codes. I got some error called:
"Unrecognized opcode: tlbwe".

I am confused and am asking for help. Thanks in advance.

Or do I missed some options for my make file? My working environment is:
*  powerpc-eabi-gcc and corresponding as....
*  I tried to use -mcpu=405 to let as know that I am expecting 405cpu:-)

#My codes sample

 li      %r0,0                 #TLB Entry 0
 tlbwe	%r4,%r0,1
 tlbwe	%r3,%r0,0

Why are you doing this?  Is something wrong with the existing
implementation?

I don't know of any compiler that has -mcpu=405 (yet).  Use -mcpu=403.
