      Hi Wolfgang,
...
Instead of vague descriptions like "something is wrong  within  TFTP"
or  "it  breaks"  you  could  try  and post the exact commands you're
trying and the exact error messages you are seing,
I am sorry for being  vague, I hope this example will make it a bit more
clear:
static void
TftpTimeout (void)
{
    if (++TftpTimeoutCount > TIMEOUT_COUNT) {
        puts ("\nRetry count exceeded; timeout error\n");
        if (image_valid == 0)
        {
            /*
             * We have no valid Linux image anymore!
             * We must start update again!
             */
             NetStartAgain ();
        }
       * else /* last image is not corrupted, I want to boot it */
        {
             /* LET ME OUT! I do not want to go back to net.c caller,
bacause I do not know how to tell him it was TIMEOUT.
                 All I can do is NetState = NETLOOP_FAIL. Not much of an
info. */
            printf("TIMEOUT error\n");
            exit (-1);
        }*
    } else {
        puts ("T ");
        NetSetTimeout (TIMEOUT * CFG_HZ, TftpTimeout);
        TftpSend ();
    }
}
...
including  information which version of U-Boot you are running
u-boot-1.1.6
...
and on which platform.
ARM9
