Try the -F option to force the file. This causes the TFTP server to ignore the
requested file name and to send the file you specify on the command line. The
idea is the DHCP (BOOTP) server does not need to be touched to change the file
you select to load using TFTP. This is how the `rtems-test` command internally
handles downloading the different tests.

... it looks like there is an issue so please run with `--show-backtrace` so I
can see where the "global name" issue is.
