Honored ContributorHow do Nios-II handle IP address change during the TCP/IP connection?
Dear all, I have problem with changing IP address in the FPGA board. Here is my case, let say I have a FPGA board which is connected to PC. The PC sends a command to the FPGA that asks th...

Honored ContributorHi Jakobjones!
I've checked the "set_ipaddr()" function and "alt_iniche_dev.c", then I made my own function to change the ip address. Here is the code :
int change_ip (int dhcp_actv)
{
alt_iniche_dev *p_dev;
NET p_net;
ip_addr ipaddr, netmask, gw;
NetInfo new_ip;
new_ip.ipaddr_in = 192;
new_ip.ipaddr_in = 168;
new_ip.ipaddr_in = 1;
new_ip.ipaddr_in = 3;
new_ip.netmask_in = 255;
new_ip.netmask_in = 255;
new_ip.netmask_in = 255;
new_ip.netmask_in = 0;
new_ip.gw_in = 192;
new_ip.gw_in = 168;
new_ip.gw_in = 1;
new_ip.gw_in = 1;
p_dev -> p_net = nets;
// Get the new ip address
printf(" Get the new ip address\n");
if(dhcp_actv) p_net -> n_flags |= NF_DHCPC;
else
{
IP4_ADDR( ipaddr, new_ip.ipaddr_in, new_ip.ipaddr_in, new_ip.ipaddr_in, new_ip.ipaddr_in );
IP4_ADDR( netmask, new_ip.netmask_in, new_ip.netmask_in, new_ip.netmask_in, new_ip.netmask_in );
IP4_ADDR( gw, new_ip.gw_in, new_ip.gw_in, new_ip.gw_in, new_ip.gw_in );
p_net -> n_ipaddr = ipaddr;
p_net -> snmask = netmask;
p_net -> n_defgw = gw;
}
return 0;
}
