MSP432E401Y: Modify NORTOS Ethernet_weather example to work with static IP

Hi,

I am working on developing a simple isolated client-server system with the MSP432 as a client and the RPi 3 as a server. 

The example uses DHCP and DNS to resolve IP address/host name. I tried changing the following:

in lwip_init(), gave a static IP, netmask and gateway of 0.0.0.0

I then attempt to start a TCP connection. No packets seem to reach the RPi.

Could anyone tell me what are the changes to made to port that example for an isolated network?

Thanks!
