Hi all,

I noticed that quite a lot of people are working on JTAG tools
for debugging on the LPC, but (as far as I know) there is still
no-one that has written an open-source gdb stub for the LPC family.
On sourceforge, there are a couple of gdb JTAG projects for arm
processors, but none seem to support the ARM7TDMI-S.

Existing closed-source software like OCDRemote and OCDCommandor
does not work well with my olimex wiggler clone and there's nothing
I can do to fix it.

Myself, I played around a bit with the sources from
http://gdb-jtag-arm.sourceforge.net/ ,
probably re-inventing the wheel but it was fun nevertheless.
So far, my progress is:
* updated parallel port access code to use libieee1284. This makes
the tool portable between windows/cygwin and linux.
* made it work with a cheap wiggler clone from olimex.
* can read JTAG idcode
* can read and write ICE registers
* can stop the processor
* read the CPU registers (not reliably yet and in wrong order)

Can we perhaps combine forces and write an open-source gdb stub?

Kind regards,
Bertrik
