Adding this block to your model provides options to configure the IP parameters for your C6000 board. Setting the options for the block sets the address and name for your board and specifies your target and Ethernet daughtercard.
To use this block with the C6416, C6713, or C6713 DSK targets, you must meet the following requirements:
Install the D.signT DSK-91C111 Ethernet adapter daughter card.
Install the Texas Instruments TMS320C6000 TCP/IP stack software.
The block uses dynamic addressing, getting the address from the local server or static addressing. If you have a dynamic host configuration protocol (DHCP) server available, you can allow the server to provide an IP address for your board. Dynamic IP addresses can be useful but unreliable — they can change.
To use static addressing, create a static IP address by clearing Use DHCP to allocate an IP address for DM642 EVM (requires DHCP server). to enable the manual IP address configuration parameters.
Note When you use the UDP Send and Receive blocks in a model, you must also include this block to set up the IP drivers for the Ethernet parameters for the target networking capability. |
Whether you choose to use dynamic addressing, you must set the Host name, and select and set the Use the following CPU interrupt for Ethernet driver (4-13) options.
When you build and run your model, this block has no effect. It outputs zeros. When you generate code from your model, this block adds the code that configures IP on your board.
The block dialog box provides options on two tabs — Device Config and IP Parameters.
Specify your C6000 target by selecting the appropriate target board from the list. Changing the target platform changes the entry on the Ethernet adapter daughtercard list.
After you select you target platform, this option lets you select whatever daughtercard is available to implement Ethernet communications on the target.
To use the UDP and TCP blocks for the board, you must install the TMS320C6000 TCP/IP Stack from Texas Instruments. Specify the folder where the TMS320C6000 TCP/IP Stack from Texas Instruments is installed.
The Ethernet driver on the DM642 can respond to any one of the CPU interrupts from 4 to 13. Enter one valid CPU interrupt for the driver to react to. CPU interrupt 13 is the default interrupt.
Shows you the segment in memory where the TCP/IP stack buffers reside. For the supported boards, the default setting and location is SDRAM. You can change the location by entering the name of the memory segment to use. TCP/IP stack buffers occupy approximately 130 kB of memory. In most cases you should locate the TCP/IP stack buffers in external memory. Be sure that the segment you specify here agrees with the memory segment allocation in the Target Preferences block in your model.
Select this option to direct the block to send IP status information to the standard output device.
Selecting this parameter configures the board to get an IP address from the local DHCP server on the network. If you select this option and you do not have a DHCP server, the generated code does not run as expected. Clearing this option enables all of the IP configuration options for the block to let you define your IP address manually.
Specify an IP address. This value is the address that others use to communicate with the evaluation module over IP. Use the full xxx.xxx.xxx.xxx format.
Define the subnet mask address, entering the full subnet mask in the format xxx.xxx.xxx.xxx. Subnet masks define how many bits of the IP address are used to identify the network.
By using 1s in all the address bits that identify the network, the subnet mask shows you which bits define the network and which are internal to the network. In the figure, the subnet mask 255.255.255.0 indicates that the first three octets in the address define the network.
Enter one address for the gateway server or router that maintains a more complete listing of the surrounding networks. Messages that are destined for machines outside the local network are sent to the gateway address for address resolution.
Enter the address of the server for the domain in which the target is a member.
Enter the name for the domain. Without the correct domain name, the target cannot communicate on the network within the domain.
Enter the name of the host. Usually this value is the NetBIOS name for the machine if it exists.
