RTEMS - FreeBSD TFTP test problem.

[Thomas Kim]

Dear Sir,

I am sorry.
At this time, I didn't use BOOTP option. therefore, I used static ethernet
IP configuration.

My ethernet configuration is below;

extern int _rtems_smsc9220_driver_attach (struct rtems_bsdnet_ifconfig
*config, int attach) ;

struct rtems_bsdnet_ifconfig lan9220_ifconfig =
{
"lan0",                   /* name */
_rtems_smsc9220_driver_attach,/* attach funtion */
NULL,                        /* next interface */
#if defined(RTEMS_USE_BOOTP)
NULL,
NULL,
#else
"192.168.137.100",           /* ip address */
"255.255.255.0",             /* ip netmask */
#endif
NULL,                 /* hardware address */
  0,                           /* ignore broadcast */
  0,                           /* mtu */
  0,                           /* rbuf count */
  0,                           /* xbuf count */
  0,                           /* port */
  0,                           /* irno */
  0,                           /* bpar */
  0                            /* drv ctrl */
};

struct rtems_bsdnet_config rtems_bsdnet_config = {
  &lan9220_ifconfig,                /* Loop back interface only */
#if defined(RTEMS_USE_BOOTP)
  rtems_bsdnet_do_dhcp,                /* do not use bootp */
#else
  NULL,
#endif
  20,                   /* Default network task priority */
  256*1024,            /* Default mbuf capacity */
  256*1024,            /* Default mbuf cluster capacity */
#if defined(RTEMS_USE_BOOTP)
  NULL,
  NULL,
  NULL,
  NULL,
  { NULL },
                        /* NTP server(s) */
  { "64.4.10.33",       /* time.windows.com (Microsoft) */
    "210.98.16.100" },  /* time.kriss.re.kr (KRISS) */
#else
  "rtems",             /* Host name */
  "nodomain.com",      /* Domain name */
  "192.168.137.1",     /* Gateway */
  "127.0.0.1",         /* Log host */
  {"61.41.153.2",      /* Name server(s) */
   "1.214.68.2" },
                       /* NTP server(s) */
  { "64.4.10.33",      /* time.windows.com (Microsoft) */
    "210.98.16.100" }, /* time.kriss.re.kr (KRISS) */
#endif
  0,                   /* sb_efficiency */
  0,                   /* udp_tx_buf_size */
  0,                   /* udp_rx_buf_size */
  0,                   /* tcp_tx_buf_size */
  0                    /* tcp_rx_buf_size */

};

Best Regards,
