[solved]DM6437 Ethernet Connection problem

Expert 1250 points


Hi,

I am having connection problem while connecting dm6437 with my pc. I need to connect to DSP over host application in dm6437_demo but I can't locate the dsp in network. Also, the connection is limited in "network connections", with the warning of "limited connection". I have tried to assing manual ip numbers but it didn't work. I think it is supposed assing ip no automatically. What should I do?

Thanks in advance.

    It sounds like you have your board connected directly to your PC, or through a switch with no DHCP server?

    The demo application is built to use DHCP, so if you do not have a DHCP server on the network between your PC and your board than it will not work properly, to get the static IP working you would have to modify app_main.c and changing the configuration from dhcp to static in the configuration section. The easiest way to resolve this sort of issue would be to put both your PC and your board on the same network subnet with a DHCP server, for example plugging both into a standard broadband router should do the trick, or just putting both on most corporate networks would also work.

    Thank you for answering.

    I don't have much knowledge about DHCP servers but as far as I know it adjusts the connection requirements (TCP/IP settings) automatically. I connect DSP directly to the ethernet in on my PC. It seems DHCP is not working because when I check connection status from network connections, there seems no DHCP Server assigned. 

    Then I need to assign static IP, as you say. I will look onto this on monday, and see what I should modify in the project. Thanks again...

    A DHCP (or Dynamic Host Configuration Protocol) server is responsible for managing the IP addresses of all devices on the network. It essentially "licenses" out an IP to any device that requests one for a given amount of time. This means that you can effectively hook up an infinite number of devices into a network without having to ensure that no two use the same IP address as the server takes care of this for you. Most home networking routers have a DHCP server built in so that you can hook up several PCs without worrying about assigning unique addresses.

    Without a DHCP server you will indeed need to configure each device with its own unique IP address. I suggest something like 192.168.1.10 and 192.168.1.20 as these are generally considered "private" IP addresses.

    I believe this particular problem was solved by using a network with a DHCP server on it (such as a home broadband router), at least that is the typical easy way to ensure network clients get an IP address.
