Hi everyone; I am currently working on at91rm9200 board (with dm9161 transceiver) and intend to use ethernet to communicate with the host pc. However, on the way to there, I found several problems. They are: -When I tried to do ping from redboot, there's message said that "Cannot reach server 192.168.0.123".
192.168.0.123 is my pc address and I set it to static IP. I tried to use ethereal and find that ARP had been broadcasted and Host PC indeed responded by sending its mac address, but my board seemed not to acknowledge it (i.e. my board kept broadcasting to my host PC until time out). Below are the capture I got from ethereal: (1) Who has 192.168.0.123? Tell 192.168.0.38 (2) 192.168.0.123 is at xx:xx:xx:xx:xx:xx and back to (1) until 8x -Try pinging from host PC was also unsuccessful but the problem source is different.The ICMPs sent by host PC were not responded by the board at all. Anyone know what's likely that cause these problems? When I used uboot and ARMLinux, the ethernet worked perfectly, so that Hardware prob is not possible. Any help would be appreciated.
