[En-Nut-Discussion] How do I generate Ethernut (Net & OS) with symbols?

Hello Chuck.

I am just a newbie here, so don't take my answer here as "the" answer, OK?.

If I want to generate the .elf file what I do is "make 
myprogramname.elf" and it works. I don't add anything special to any 
file. Actually "myprogramname" can be anything, and it will generate the 
.elf file with that name (for example "make lalala.elf" will exactly 
generate a file named lalala.elf)

here is an example of the output of the process for a projects which 
main  file is pemctrl.c

$ make pemctrl.elf
avr-gcc pemctrl.o  xflash.o tftp.o pbtwique.o PemBoard.o PbDebug.o 
-mmcu=atmega128 -Wl,--defsym=main=0,-Map=pemctrl.map,--cref 
-Lc:/ethernut-4.0.1/nutbld/lib c:/ethernut-4.0.1/nutbld/lib/nutinit.o 
-lnutarch -lnutnet -lnutpro -lnutfs -lnutos -lnutdev -lnutnet -lnutcrt 
-o pemctrl.elf

$ make hh.elf
avr-gcc pemctrl.o  xflash.o tftp.o pbtwique.o PemBoard.o PbDebug.o 
-mmcu=atmega128 -Wl,--defsym=main=0,-Map=pemctrl.map,--cref 
-Lc:/ethernut-4.0.1/nutbld/lib c:/ethernut-4.0.1/nutbld/lib/nutinit.o 
-lnutarch -lnutnet -lnutpro -lnutfs -lnutos -lnutdev -lnutnet -lnutcrt 
-o hh.elf

I cannot answer the rest of your questions. I am also struggling trying 
to debug. Hope this helped anyway.
