Hi I am using a Mini2440 Board and using Uboot-1.3.2 on it. I am connecting it to a my Host Machine which has Ubuntu 11.04 on it. After downloading the Uboot image on the board, through USB, I am able to boot up and set the environment variables like ipaddr,serverip, netmask and ethaddr, to connect to my host machine.
Settings on mini2440 are - setenv ipaddr 192.168.1.2 setenv serverip 192.168.1.4 setenv netmask 192.168.1.255 saveenv The address of eth0 on my Ubuntu machine is 192.168.1.4. The host and mini2440 are connected directly though a network cable. The serial and USB interface of mini2440 are also connected to the same host. Now after setting the environment variables I try to do a TFTP from my mini2440, then I see ARP requests being sent out, which are received by the host and replied back( This I monitor using Wireshark) . But I dont see any message being received back on Mini2440. I have enabled network level debug prints and I am not able to see any packet receive print. I dont think its a Physical layer issue as the ARP packets are transferred correctly. I am missing out some configuration or some flag/switch during my build. Regards & Thanks.
