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?
