Hi,

	Which USART is used for ISP programming? I looked in the user manual
and it says it can be done, but nothing about which port on the LPC2138.

Regards,
Charles

Yes, you can program the Flash through the JTAG port, but it won't be fast
and it will be a bit of work to get production quality software running
(meaning "push this button to program").  

IIRC, all of the LPC parts come with a serial port boot loader that should
be a bit easier to get running for your needs.  Can you use the serial port?
If you don't want the RS232 transceiver on your board, you can use a paddle
board for that.  If you don't want the cost of a connector on the board, you
can use a card edge connector or even a clamp on connector.
