but there is one issue i used lpc2148 trainer board for interfacing fp..in that pin.0.8 showing 0 voltage and i cant get proper response from fp

pin 0.8 and pin 0.9 are used for receive and transmit data for UART1....and i used UART0 for transmitting data and uart1 used for showing response from fp....

Are you still having problems ?

because FP data is reading by using UART1 and TX AND RX pin of uart1 is connected to pin0.8 & pin0.9 and TX show 0 volt.

Can you give a link to the lpc2148 trainer board you are using.
Are you able to program the board to do anything ?
Do you have any demo software that transmits on UART1 ?
