I am using LPC1768 Development board. I have successfully used Easyweb example given in keil with my board. its working when i am connecting my board directly to one of my pc. Everything is working fine but when i connect my board with LAN and access my board with one of my PC in LAN.... that time its not working properly.... means i am getting ARP request.... it is getting processed and also sent reply but PC that has sent the ARP request is not getting this reply. My board and PC is connected through dlink switch. I am afraid Switch is dropping my packets.
Any suggestions??!!!
it it written in datasheet that pin 20 and pin 21 of DP83848 must be connected to 3.3 V through 2.2 K ohm resistor but in my board that pin has been left float.
can it be a problem?
