I doubt that it makes much sense to buy the adapter.
Please have a look at page 4 of the schematics for the lpcxpresso 1769
Board ( first pdf document hit when you google for "lpcxpresso 1769
schematic") there is clearly stated:
"J5 can connect to external SWD/JTAG interface if LPCXpresso targetside
(LPC17xx) is disconnected."
so it seems that you cannot connect an external JTAG debugger to this
10pin connector without some extra work.
You could remove all the 100 Ohm resistors R23 R24 R25 R26 R28 and R30,
then you could use your adapter if the pin layout of the adapter
matches. But cutting the board in two peaces looks easier to me ,-)

what about using a board like so
http://www.ebay.com.au/itm/280970074709?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649
to covert an existing jtag debugger i use ? ( this one i have ->

LPC1343 Board uses a special JTAG interface that does not have open
sourced driver support.
So if you do not want to use their GUI (based on Eclipse if I remember
correctly) which is mainly C/C++ based then the easiest way is to cut
the board in two pieces and to then connect it to an inexpensive ST-link
V2 based JTAG probe or another JTAG probe that is supported by openocd
project (At least on the mac it makes more sense to use an olimex JTAG
probe together with openocd because stlink v2 support is quite new).
I have found this nice tutorial on how to connect the board to another
JTAG debugger: https://uwe-arzt.de/20130115.html
I am currently extending Lazarus so that it natively supports connecting
to a debugserver, I still have some problems with initial run command
but if you can wait a few days you can help testing this integration.

I've been following the wiki and have successfully created fpc for my
arm processor ( Cortex M3 - using a LPC 1343 board) ( as per the wiki's
intructions)
once i have written my sample program is there anyway to debug it on
the
MCU ? ( ie like doing in Lazarus for win32/64 projects)
any help would be of much benefit

Hi,
Mostly you debug via gdb. Depending on the board us can use jtag
(e.g. openocd) or another hardware-interface. Some STM32 boards have
an ST-link interface.
P.S. what version of fpc did you use (svn-revision) ? I'm asking
because I'm having troubles with my cross-compilers. At the moment
I'm making a virtual appliance with fpc 2.6.0 for 386 and some
revisions of trunk. I made some scripts to compile the crosscompiler.
This way interested people can look into the problems.
And when there is a usable compiler, I can make the appliance to
share it with interested users.
Regards,
Koenraad Lelong
