Some TFTP servers are pickier than others.  Sometimes you need to give the
complete pathname (e.g. on Red Hat 7).  Other times, you may need to specify
the file name in some other "absolute" fashion, e.g. 
  load /hello.srec

Try turning on network debug (you may need to force this because you don't 
have flash/fconfig).  This will show you packets as they go in/out of your
machine, which may help identify the problem.

Have you run any of the eCos networking tests using your driver?  It would
be nice to see how they fare, especially the throughput tests.
