TIVA TM4C129XNCZAD: Setting static IP

Dear Members,

The example: enet_lwip contains the following line:

lwIPInit (g_ui32SysClock, pui8MACArray, 0, 0 ,0, IPADDR_USE_DHCP);

With this line, the evaluation board gets an IP address from DHCP server.

I changed it to:

lwIPInit (g_ui32SysClock, pui8MACArray, inet_addr ("3.1.168.192"), inet_addr ("0.0.255.255"),0, IPADDR_USE_STATIC);

But it seems the TIVA does not get the proper IP address: 192.168.1.3

I opened an Internet browser with this address and got nothing.

I also tried the line:

lwIPInit (g_ui32SysClock, pui8MACArray, 0xC0A80103, 0xFFFF0000,0, IPADDR_USE_STATIC);

and got the same problem.

There is a line:

Ui32NewIpAddress = lwIPLocalIPAddrGet ();

The value if Ui32NewIpAddress is not the new IP.

Can you help ?

Thanks,

Zvika

Hello,

Now the display is showing the new IP address !

But it seems the TIVA is not responding to ARP requests from the PC (running windows).

I had to add "arp -s 192.168.1.1 00-10-4B-BC-33-75".

Is it possible that the TIVA will respond to ARP ?

Same question for PING.

Thanks,

Zvika

My board does not respond to Ping either. It appears more investigation is required.

Perhaps someone from TI will chime in.

Hello,

I set the TIVA to a free static IP address and connected it to the company's network.

There was a reply to ping from linux but no reply for ping from windows.

When I pinged from windows, according to etherent sniffer, TIVA returned a reply but windows diagnosed "timeout"

Thanks,

Zvika

For us also pinging the device does not work... Any hints are appreciated.

Hi Daniel,.

2538.lwipopts.h

To work with static IP I had to do 2 minor changes in the file lwipopts.h

The changes are marked with: /* Z.V */

This file is taken from the last version of TivaWare: 2.1.0.12573

I recommed to start with the original example project and replace only the attached file.

Let me know if you need further help.
