Using gcov for embedded systems

[Channagoud <ckadabi@xxxxxxxxxxxxxx>]

Hi,
I am trying to use gcov to find out code coverage on my bootloader code.
But I don't have a file system present. So not data us being captured 
for the code coverage.

Is there a way to find code coverage for my case?
Or are there any other tools present to achieve this?

Thanks,
Channa
