it's about the to send program to LPC-H2148 olimex board

[LPC2148]

Hi all,

I will start to use lpc-h2148 arm board.I have it. I wrote program.
I have a few question which I don't know.
I don't have jtag module
I have paralel and serial port on my pc

question 1) I want to upload program to arm board, Could I upload program via USB port on the arm board? ( I did not try it)

question 2) Could I upload program with USB to TTL  only by using TX,RX,GND?
There are 5 pin on the USB to TTL (+5V,TXD,RXD,GND,+3V)

baund rate 9600
I tried like this, but failed

USB to TTL >>>> LPC2148
TX         >>>> P0.1 RX
RX         >>>> P0.0 TX
GND        >>>> GND

I need your answer and ideas
with best regards,

I value my time and a JTAG device is cheap (plus provides helpful things you don't get via serial ISP).

Otherwise, the LPC manuals give you full details
