LPC2148 with ENC28J60

Hi

I have connected LPC2148 with 12Mhz Crystal, 15 Mhz PCLK to ENC28J60 with the following PIN Connections.

ARM ENC28J60
PO.4 >>>>> SCK
PO.6 >>>>> SI
PO.5 >>>>> SO
PO.7 >>>>> CS

RESET PIN of ENC28J60 is connected to hardware reset PIN of LPC2148. I have been able to run the compiled program in Proteus and was able to PING the configured IP. No problem at all.

When I run the same with real hardware... it doesnt work. I dont even get a PIN response. What could be the problem ? Should I do anything more with the hardware? Please advise.

Thank you.
