Milos,
 
One of the problems we've seen is that parallel port cables are just too
long going to the Wiggler.  What you can do is just reduce the JTAG
frequency in the target interface (i.e. increase the frequency divider I
think) and see if that works for you.  Alternatively, try a shorter or
higher quality parallel cable.

	Hi everyone,

	I've been developing stuff with LPC for some time now... 

	Initially I've been playing with Ashling software tools, then I
build my own board and used Philips ISP to download code... but now that
the code complexity and size is increasing I purchased the Macraigor
Wiggler and started evaluating CW for ARM. Since everything so far was
done in GCC, I'm expecting no complications in moving the project to CW.


	However, I'm having some issues with flash downloads. Wiggler
seems to detect something on the JTAG (0x4F1F0F0F).. and when I try
downloading a hex or binary file it looks like it's erasing and then
downloading but the memory content stays the same - whatever was in
flash before didn't get erased, not to mention overwritten.

	If anyone knows what's the trick to get the LPC210x to work with
CW/Wiggler I would be very grateful.

	Thank you in advance,

	m.
