what option and where do you put the option in order to generate a memory mape of my compiled SW using DevKit Advance/gcc ?
I'm trying to figure out if the code I compiled to be located in iwram is really getting there.
Thanks

| Code: |
-Wl,-Map somefile.map [other linker options]
|
put that option on the command line where you compile your elf and you'll have a mapfile generated

I tried -Map x.map and -map x.map both gave me this error
gcc: x.map: No such file or directory
make: *** [x.elf] error 1
this is my makefile command line:
CFLAGS =
-O1 -Wall -save-temps -fverbose-asm -mthumb-interwork -mlong-calls
LDFLAGS =
-lm -w -mthumb-interwork -mlong-calls
$(TARGET).elf : $(OFILES)
gcc -Map $(TARGET).map $(LDFLAGS) $(OFILES) -o $(TARGET).elf

Yes the -Wl option is important and it won't work unless you have it.
Also, this will work:
| Code: |
gcc -Wl,-Map $(TARGET).map $(LDFLAGS) $(OFILES) -o $(TARGET).elf
|
but this won't:
| Code: |
gcc -Wl, -Map $(TARGET).map $(LDFLAGS) $(OFILES) -o $(TARGET).elf
|
It's important that there's no space after the -Wl,

Thanks for the help. the only one I tried was:
| Code: |
| gcc -Wl,-Map,$(TARGET).map |
It worked great....
