When "something  is  wrong  within  TFTP",  the  respective  function
returns an error code, which propagates upward and causes the running
command  to terminate, so you automatically end up back in the U-Boot
shell.


Maybe you should explain what exactly you are trying to  do.  I  have
the feeling that your question does not describe your actual problem,
and  that your actual problem might be either be based on a misunder-
standing or inappropriate use.

Best regards,
