    I want to program LPC2148 ARM processor. I have developed a board with USB port and RS232 IC. I have taken 6 pins out 1. Reset 2. txd 3. rxd 4. grnd 5. vcc 6. program.
    I have LPC2148 ARM processor and have made following connections to program the processor.

    usb board micro-pocessor

    1. Reset - pin n.o 57 (reset')
    2. txd - pin n.o 21 (RXD0 - P0.1)
    3. rxd - pin n.o 19 (TXD0 - P0.0)
    4. grnd - any vss on the chip.
    5. vcc - any vdd on the chip.
    6. program - pin n.o 14 (P0.14 SDA1)

    I am using flash utility software to program my IC.
    baud rate - 9600.
    correct port selection.
    frequency - 12 mhz .
    correct hex file.

    still my IC is not getting programmed.
    I am getting the error as error in step1.

    plz can you tell where I am wrong? Or what i may be missing?
