After linking with the application to form an image The debug symbols
will be in place, but just symbols you need. The debug information for
symbols that are not in the image will not be in the image.

There is also no need to strip the image before loading it onto the
target. Your BDI2000 will be able to parse the elf image and download
only what is needed onto the target, ie it won't download the debug
information.
