Lpc2000

I have two JTAG adapters that I use with the ARM ADS and RVDS tools.
The first is a Lauterbach ICD, which I use for just about everything I
do, the performance is excellent,  The user interface is not great but
usable, it is scriptable, and it even comes in Ethernet and USB
versions, but it is not cheap.  And as far as I know it will support any
tool chain that produces an ELF/DWARF image.  They can be found at
http://www.lauterbach.com.

The second adapter is an EPI Majic.  They have never been able to make
it work with the Sharp ARM9 I'm using but it seems to work OK on the
LPC21xx parts that I've tried.  Their tech support has been terrible and
I would not recommend them except as a last resort.

Looking at the list of JTAG adapters here:
http://www.open-research.org.uk/ARMuC/index.cgi?action=browse&diff=1&id=
JTAG_Interfaces&revision=7

It seems that chameleon pod is good: can behave as wiggler or raven (but
faster than wiggler), supports GNU GDB, affordable. What I don't like is
the parallel interface, most laptops don't have parallel ports anymore.
Seems amontec is working on a USB version of chameleon pod but its not
available yet and I'm sure it will cost a lot more.

It seems like these tools vendors want us to buy a starter kit with JTAG
for every variant of processor we work with. I find it very annoying to
see "JTAG for LPC2000" and such, these are all ARM cores.

I wish there was some schematics around for building a USB JTAG adapter
for ARM. I wonder: could a USB parallel port adapter be used with a
wiggler and still work with ocdremote?
