RTEMS BSD Net on Atmel SAM Board

[Isaac Gutekunst]

A brief update: I've updated my configuration from a different example to be a bit more complete. It looks like it can't communicate with the PHY.

#if (defined (RTEMS_SET_ETHERNET_ADDRESS))
   static char ethernet_address[6] = { 0x00, 0x04, 0x9F, 0x00, 0x5B, 0x21 };
#endif


static struct rtems_bsdnet_ifconfig netdriver_config = {
         RTEMS_BSP_NETWORK_DRIVER_NAME,          /* name */
         RTEMS_BSP_NETWORK_DRIVER_ATTACH,        /* attach function */
         NULL,                           /* No more interfaces */
#if (defined (RTEMS_USE_BOOTP))
         NULL,                           /* BOOTP supplies IP address */
         NULL,                           /* BOOTP supplies IP net mask */
#else
         "192.168.0.140",                /* IP address */
         "255.255.255.0",                /* IP net mask */
#endif /* !RTEMS_USE_BOOTP */
#if (defined (RTEMS_SET_ETHERNET_ADDRESS))
         ethernet_address,               /* Ethernet hardware address */
#else
         NULL,                           /* Driver supplies hardware address */
#endif
         0,                              /* Use default driver parameters */
         0,                              /* mtu */
         0,                              /* rbuf_count */
         0,                              /* xbuf_count */
         0,                              /* port */
         39                               /* irq */
};



struct rtems_bsdnet_config rtems_bsdnet_config = {
         &netdriver_config,
         NULL,
         0,                              /* Default network task priority */
         16 * 1024,                     /* Default mbuf capacity */
         16 * 1024,                     /* Default mbuf cluster capacity */
         "rtems",                /* Host name */
         "nodomain.com",         /* Domain name */
         "192.168.0.14",         /* Gateway */
         "192.168.0.1",          /* Log host */
         {"192.168.0.1"  },      /* Name server(s) */
         {"192.168.0.1"  },      /* NTP server(s) */
         0,                      /* efficiency */
         0,                      /* udp TX buffer */
         0,                      /* udp RX buffer */
         0,                      /* tcp TX buffer */
         0,                      /* tcp RX buffer */
};


I also added the network shell commands and can ping myself on 192.168.0.140. ifconfig atsamv0 shows:

***** atsam0 *****
Ethernet Address: 48:11:40:20:45:01
Address:192.168.0.140   Broadcast Address:192.168.0.255   Net mask:255.255.255.0
Flags: Up Broadcast Running Simplex Multicast
Send queue limit:50   length:0    Dropped:0
-E- TimeOut ReadPhy


This matches the slow blinking of both LEDs at about 0.5Hz.
