Hi,
I have a STM32F746 that I am able to send/receive IPV4 UDP messages and it working just fine.
Now I try to move from IPV4 to IPV6. I am using CubeMx to configure my STM32F746.
The first step is to ping the device but I cannot reach the STM32F746.
According to the print out in MX_LWIP_Init() the IPV6 address is FE80::8000:0:0:E1
So I tried the the following but failed:
C:\Users\ajn>ping FE80::8000:0:0:E1
Pinging fe80::8000:0:0:e1 with 32 bytes of data:
Destination host unreachable.
The ip address of the PC is:
Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : fe80::b034:7349:9aec:332e%5
IPv4 Address. . . . . . . . . . . : 192.168.0.101
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.0.1
I am little bit lost when it comes to this IPV6 addresses, so may I am not using the correct ones.
Do you have any suggestion how I can solve this problem?
I have following code in:
int main(void)
{
...
MX_LWIP_Init();
...
while (1)
{
/* Read a received packet from the Ethernet buffers and send it to the lwIP for handling */
ethernetif_input(&m_gnetif);
// Checks if Ethernet link is up or down
ethernetif_set_link(&m_gnetif);
/* Handle timeouts */
sys_check_timeouts();
}
}
void MX_LWIP_Init(void)
{
/* Initilialize the LwIP stack without RTOS */
lwip_init();
/* add the network interface (IPv6) without RTOS */
netif_add(&gnetif, NULL, ðernetif_init, ðernet_input);
/* Create IPv6 local address */
netif_create_ip6_linklocal_address(&gnetif, 0);
netif_ip6_addr_set_state(&gnetif, 0, IP6_ADDR_VALID);
gnetif.ip6_autoconfig_enabled = 1;
my_printf("%s: ", ip6addr_ntoa(netif_ip6_addr(&gnetif, 0)));
/* 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);
}
/* Set the link callback function, this function is called on change of link status*/
netif_set_link_callback(&gnetif, ethernetif_update_config);
/* Create the Ethernet link handler thread */
/* USER CODE BEGIN 3 */
/* USER CODE END 3 */
}
