FNET Change Static IP

[pcpro178]

My application uses a static IP address, but it needs the ability to change the IP address and subnet mask through software. Is there a way to do this without modifying the FNET stack?

I found that I could set the IP addresses during run-time using `fnet_netif_set_ip4_addr` and `fnet_netif_set_ip4_gateway`.  I mapped some memory space in flash to store the addresses while powered-down, and my application restores them using those two API calls at power-up.

Hi Jim:

According to Fnet Quick start:

You are able to change the default network pararmeters

• By using Shell commands:

• set address <default-if IPv4 address>

• set gateway <default-if IPv4 gateway address>

• set netmask <default-if IPv4 netmask address>

• By changing the default values in the fapp_user_config.h source file. 
  Your local system administrator is able to assign a unique IPv4 address for the board, and also provide you with the IPv4 addresses of the gateway and the netmask.
