I think you're right: it's trying to open a file from a tftp mount. The API
to RTEMS' TFTP was changed a couple of months back.

Now you need something like this (from network-demos/tftpTest/init.c):

#include <rtems/libio.h>

rtems_bsdnet_initialize_network ();
mount_and_make_target_path (
         NULL,
         "/TFTP",
         RTEMS_FILESYSTEM_TYPE_TFTPFS,
         RTEMS_FILESYSTEM_READ_WRITE,
         NULL
);
