We have connected the LPC1768 evaluation board to PC directly over a crosslink network cable. (Ethernet PHY DP83848C)
"Keil HTTP Server(MCB1700)Compact web server with CGI interface" example code loaded into on-chip flash.
Web server page open successfully when we connect board to PC directly over a crosslink network cable.
But when we connect board to PC via Ethernet switch(DLink DES-1008CE) over a straight network cable web server page can not open.In this case the when we ping from PC site it's show the error message "Destination Host Unreachable".
Sounds like a typical network address issue. Check IP addresses, masks etc.
Troubleshoot the example project: www.keil.com/.../network_troubleshoot.html http://www.keil.com/support/docs/4056.htm http://www.keil.com/support/docs/3784.htm
Thanks for replay,
When we put LPC1768 board in local network through router it is work but problem come only when board connect to network through switch.
