Did you build "test" using bfin-uclinux-gcc? What is the output if you run "file test"?

you cannot objdump a FLAT binary by default.  do it on the .gdb file.

Hi Mike

            Thanks for the suggestion,

              You are right mike, its a FLAT binary file only.

           I will try on .gdb file.

and you then ran `bfin-uclinux-objdump -d NetFrame.gdb` ?  your build code doesnt move files around right ?

run `file NetFrame.gdb` and post the output

doing this works fine for me:

$ echo 'int main(){}' > test.c

$ bfin-uclinux-gcc -elf2flt test.c -o test

$ file test test.gdb

test:     BFLT executable - version 4 ram

test.gdb: ELF 32-bit LSB executable, Analog Devices Blackfin, version 1 (SYSV), statically linked, not stripped

$ bfin-uclinux-objdump -d test.gdb

test.gdb:     file format elf32-bfin

Disassembly of section .text:

00000000 <__start-0x4>:

   0:   00 00           NOP;

Hi Mike,

            As per your suggestion, i had tested my toolchain using the simple application.

PF> echo $PATH

/opt/uClinux/bfin-uclinux/bin:/opt/uClinux/bfin-linux-uclibc/bin:/opt/uClinux/bfin-uclinux/bin:/opt/uClinux/bfin-linux-uclibc/bin:/opt/uClinux/bfin-uclinux/bin:/opt/uClinux/bfin-linux-uclibc/bin:/home/psenthil/bin:/usr/local/bin:/usr/bin:/usr/X11R6/bin:/bin:/usr/games:/opt/gnome/bin:/opt/kde3/bin:/usr/lib/jvm/jre/bin:/usr/lib/mit/bin:/usr/lib/mit/sbin:/usr/lib/qt3/bin

PF> bfin-uclinux-gcc -elf2flt testcase.c -o ToolchainTest

below are the display of the test applciation.

PF> file ToolchainTest ToolchainTest.gdb

ToolchainTest:     BFLT executable - version 4 ram

ToolchainTest.gdb: ELF 32-bit LSB executable, version 1 (SYSV), statically linked, not stripped

PF>

So, from the above testing we will confirm that toolchain is installed properly.

so run the single command by hand:

bfin-uclinux-gcc -o ./NetFrame  ./DPFApp/DPFMain.o    ./DPFApp/Initialization.o     -Wl,-elf2flt  -ladiOSA -lJITask -lpthread -lFWGUI   -L/home/psenthil/DPF/uclDPF/lib

then you might want to check your build system to make sure it isnt renaming files and thus clobbering the .gdb
