Examples how this can be configured are available in most (all) of the
Makefiles from the WinARM-Examples collection for LPC2xxx available in
examples-directory of the WinARM distribution-package or at
http://www.siwawi.arubi.uni-kl.de/avr_projects/arm...

(1)
Somewhere in a Makefile you can add some configuration-options as
"variables":

#
------------------------------------------------------------------------ 
---
# Flash-Programming support using lpc21isp by Martin Maurer
# only for Philips LPC and Analog ADuC ARMs
#
# Settings and variables:
LPC21ISP = lpc21isp
LPC21ISP_PORT = com1
LPC21ISP_BAUD = 38400
LPC21ISP_XTAL = 12000
LPC21ISP_FLASHFILE = $(TARGET).hex
# other options:
# * verbose output: -debug
# * enter bootloader via RS232 DTR/RTS (only if hardware supports this
#   feature - see Philips AppNote): -control
LPC21ISP_OPTIONS = -control
#LPC21ISP_OPTIONS += -debug
#
------------------------------------------------------------------------ 
---

Than add a program target to your makefile:

program: $(TARGET).$(IMGEXT)
--->$(LPC21ISP) $(LPC21ISP_OPTIONS) $(LPC21ISP_FLASHFILE)
$(LPC21ISP_PORT) $(LPC21ISP_BAUD) $(LPC21ISP_XTAL)

"--->" to be replaced by a tabulator. All $(LPC21ISP_*) in one line.

With this entries a make program will start lpc21isp with the given
parameters

Hope this helps,
