[ECOS] GDB and Symbol Debug need help

["pb.jack" <pb dot jack at powerbase dot com dot tw>]

Hi,
I'm newbie or eCos, my toolchain is win2k+eCos+GDB+Multi-ICE, I can have
my test program running on the target board now, however, I can't view
the symbol value from the GDB, I suspect there are something wrong in my
compile and link setup, can somebody take a look at my makefile?

make -f makefile run.bin
copy /y run.bin \downfiles\run.bin
pause
