[FAQ] TMS320C6657: NIMU EMAC example for C665x processor from TI-RTOS SDK

To run the NIMU EMAC example for C665x devices make sure the pre-requisites are present.

1. CCSTUDIO_9.3.0.00012 (https://www.ti.com/tool/download/CCSTUDIO/9.3.0.00012),
2. PROCESSOR-SDK-RTOS-C665x  (Version: 06_03_00_106 ) (https://software-dl.ti.com/processor-sdk-rtos/esd/C665x/latest/index_FDS.html)
3. Example projects are generated (https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1040872/faq-tms320c6657-how-to-generate-the-ccs-pdk-examples-for-c6657).

Now Import the CCS project into CCS and go on

1. To Import the project goto File -> Import -> "CCS projects" in "C/C++" -> Browse "Select Search-directory". make sure to uncheck the "Copy Projects into Workspace" (This is to avoid compilation errors only If TI-RTOS SDK was installed in a different location than "C:\ti\").
2. In the project "NIMU_emacExampleClient_EVMC6657C66BiosExampleProject",
   1. Modify the following lines to configure the IP as static.

      // IP Configuration
      //
      
      char *HostName    = "tidsp";
      char *LocalIPAddr = "192.168.1.4";
      char *LocalIPMask = "255.255.255.0";    // Not used when using DHCP
      char *GatewayIP   = "192.168.1.1";    // Not used when using DHCP
      char *DomainName  = "demo.net";         // Not used when using DHCP
      char *DNSServer   = "0.0.0.0";          // Used when set to anything but zero
      
      
      ... 
      
      
      /*
       * Main thread
      */
      int StackTest()
      {
          ...
          
               
          if(1) // set '1' for manual IP configuration
          { 
              // Manual IP configuration 
              CI_IPNET NA;
              CI_ROUTE RT;
              ...
              
          }
          else
          {
              //DHCP configuration
          }
          
      
      }

   2. Modify the following lines to configure the IP by the DHCP server.

      int StackTest()
      {
      
          if(0) // set '0' for DHCP IP configuration
          { 
              // Manual IP configuration 
              CI_IPNET NA;
              CI_ROUTE RT;
              ...
              
          }
          else
          {
              //DHCP configuration
          }
      }

3. Now, Load the binary into the DSP core (By default on Core 0).
4. In the "Console" window, 
   1. The following output will be shown for the successful setting of static IP,
   2. The following output will be shown for the successful setting of IP by DHCP service, 
5. From the Output console, you can deduce that Along with DHCP service "Telnet" and "HTTP" service are also online.
   1. Telnet can be verified by connecting to the device IP and port 23.
   2. HTTP (webserver) can be verified by connecting to device IP and Port 80, Along with this, we can also view the web page stored in memory.
