Hi rushin,
You have to use Com0(P2) for ISP progamming.And must put jumpers J1 & J10.Before press Start key in Flashmagic,reset the board more then ones.

i did but.when i am using flash magic to verify connection i get error ' unable to communicate .ensure no other applications are using COM port. try raising or lowering baud rate

For this error means,you have to ensure the same Port used as any other application.(Close all Com Port Applications) only the Flash Magic is Opened.

Before Start the program ,ones Read the Device (LPC2148 will detect) using Flash Magic.

Check the Cable configuration also..
