TM4C1294NCPDT: Problems with manual configuration of DHCP or Static IP

Part Number: TM4C1294NCPDT

Hi all,

  I have used TM4C processor and also my project is running using the XGCONF config for DHCP resolution.

  It works fine, the IP is obtained fast and I have no problems with this approach.

  Now I have a request where I need to implement the support to choose the IP resolution type on demand, I mean, the use can access the configuration panel (Usually, I do the config using sockets or via uart).
  But I am having a problem when trying to set dynamically the DHCP or IPaddress. The NC_NetStart is not working and I don't know how to fix it.

  I am using tcpEcho to try to fix it and, after that, put the solution on my project.

  I am using TI-RTOS 2.16.1.14.

  The error I am getting is the following:

Starting the TCP Echo example
System provider is set to SysMin. Halt the target to view any SysMin contents in ROV.
Service Status: DHCPC : Enabled : : 000
Service Status: DHCPC : Enabled : Running : 000

	return(0);
}



Void startupTask(UArg arg0, UArg arg1) {
	NetworkConfig();
}

The startupTask is called by BIOS, as a Task.

Any clue? I already take a look at several posts but didn't find a way to fix it.

Does anyone has a project tcpEcho with manual configuration to share?

Tks in advance

Leandro

    Hi Leandro,

    You are missing some items (e.g. creating a Clock Object) in you configuration. I'd use XGCONF to generate the networking stack thread code and then copy it out of the generated source file in Debug\configPkg\package\cfg (e.g tcpEcho_pem4f.c). Search for the ti_ndk_config_Global_stackThread and copy it (and any functions it calls). Note: you might do the same trick for the static IP to see the difference. You should be able to easily add in the isDHCP check.

    Hi Todd,

    As fas as I understand, the tcpEcho_pem4f.c is the generated code based on XGConf parameters, so, the idea is to use this code as a base to my own config.
    Is that right?
    Maybe what I need is just the clock.
    I will take a look and let you know.
    Tks for help

    Yes, tcpEcho_pem4f.c is the generated code based on XGConf parameters. So you use XGCONF as you have in the past. Copy the code that configures the stack out of tcpEcho_pem4f.c and place it in your own source file. Then remove the XGCONF configuration for the stack (so the code is not generated).
