I'm using stm32f407VET6 to work with ethernet using KSZ8895 ethernet switch. To generate the basic MII configuration I'm using STM32 cubeMX. While doing the Ping test I am getting the error 'Destination Host unreachable'.

[RJOY.1]

 There is any issue while generating ethernet code using  STM32 cubeMX. The tool chain I am using is TrueStudio. Please help. lwip initialization code is below.

void MX_LWIP_Init(void)

{

IP_ADDRESS[0] = 192;

 IP_ADDRESS[1] = 168;

 IP_ADDRESS[2] = 100;

 IP_ADDRESS[3] = 1;

 NETMASK_ADDRESS[0] = 255;

 NETMASK_ADDRESS[1] = 255;

 NETMASK_ADDRESS[2] = 255;

 NETMASK_ADDRESS[3] = 0;

 GATEWAY_ADDRESS[0] = 192;

 GATEWAY_ADDRESS[1] = 168;

 GATEWAY_ADDRESS[2] = 100;

 GATEWAY_ADDRESS[3] = 3;

 /* Initilialize the LwIP stack with RTOS */

 tcpip_init( NULL, NULL );

 /* IP addresses initialization without DHCP (IPv4) */

 IP4_ADDR(&ipaddr, IP_ADDRESS[0], IP_ADDRESS[1], IP_ADDRESS[2], IP_ADDRESS[3]);

 IP4_ADDR(&netmask, NETMASK_ADDRESS[0], NETMASK_ADDRESS[1] , NETMASK_ADDRESS[2], NETMASK_ADDRESS[3]);

 IP4_ADDR(&gw, GATEWAY_ADDRESS[0], GATEWAY_ADDRESS[1], GATEWAY_ADDRESS[2], GATEWAY_ADDRESS[3]);

 /* add the network interface (IPv4/IPv6) with RTOS */

 netif_add(&gnetif, &ipaddr, &netmask, &gw, NULL, &ethernetif_init, &tcpip_input);

 /* Registers the default network interface */

 netif_set_default(&gnetif);

 if (netif_is_link_up(&gnetif))

 {

  /* When the netif is fully configured this function must be called */

  netif_set_up(&gnetif);

 }

 else

 {

  /* When the netif link is down this function must be called */

  netif_set_down(&gnetif);

 }

Thanks in advance.
