Re: Establishing ethernet support, ping failure

Hello,

We are trying to add the networking support for Hitachi 7729 hardware. we have removed the network support from Redboot and downloading application through serial port.

Application is built with network support configuration (freeBSD)

We testing the network support added with ping command.

Loopback test on the board with ping command works fine.
(ping 127.0.0.1 works fine on the board)

But there is no response, when we ping the board from host PC or ping host PC from the board.
(ping timeout)

pls give us the solution

Have you enabled any debug messages in your build ? What do they say ? You can turn on debug in the Common Ethernet Support package (CYGDBG_IO_ETH_DRIVERS_DEBUG). You may also be able to enable extra debug in the Ethernet driver itself.


Have you checked with Ethereal/tcpdump whether any traffic is actually leaving your board ? Do you have any LEDs on the Ethernet port, and do they light up when you start your application ?

Can you see any messages like "client IP: 10.0.0.1" when you start your application ? Depending on your configuration it may be necessary to call init_all_network_interfaces() in your applicaiton. However, if loopback is working then maybe this isn't necessary.

Without more information like this it is difficult to guess what your problem might be.

Kelvin.
