Hi Chirag,

What are using. Simulator or emulator?
In case of simulator, go to Options->memory map and
allocate the entire range as RAM.

In case of emulator(board), you would need to study
the memory map of the specific board (provided in
accompanying documentation) and modify the linker
command file accordingly. Since your text segment
seems to be too large, my guess is that it might not
be fitting in your internal Ram, and you might need to
partition it and place some of it in external memory. Regards
Piyush

Chirag-

Follow what Piyush has told and determine the memory map. Then
determine how much you can allocate and where post that details with
ur version of cmd file and someone from the group mite b able to
comment on that.

Hope this helps

Chirag-
My two cents. Looks like you are trying to load a 100 kb code, like
g729a into the internal memory of a processor like 6711. If thats the case
then your problem figures:

1]Optimze your code size vs execution speed: weight it more towards code
size, if the mips requirement allows that liberty

2] Eliminate all unnecessary printf's and other File I/O kind of
functions(they consume a lot of memory and MIPS too)

3]Put all un-eliminatable(?) rts functions into external memory instead of
internal memory by saying:

.rtstext >SDRAM
.rtsbss > SDRAM
.rtsdata > SDRAM

in your linker command file.

4] Avoid functions calls to basic_op by making inlining them, optimsed with
intrinsics

5]Dont use -O3 -bhooshan
