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:-)

#Error Message I got from compiler and assember

: Error: Unrecognized opcode: `tlbwe'
: Error: Unrecognized opcode: `tlbwe'
#-------------
#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.
