Run the source file through gcc with -g -S, and have a look at line
232.  This could be a gcc or assembler problem, knowing what the
offending instruction is would help.

The linker will write an output file, using ELF, EABI or some other
format (depending on what you tell it) that contains your program.
Use objcopy to convert it to S-record or Hex, and use a chip burner to
burn it into the flash on your target system.

You could also feed the output file to gdb and debug remotely, if your
target hardware has a suitable debugging agent.  See my article on
implementing a remote debugging agent at http://billgatliff.com for
more on what I'm talking about.
