Cable lengths are a problem with JTAG wigglers (JTAG in general, even 
high end units could have that problem).  When using a wiggler on an 
SA1100 project (also ARM), that anything more than 10inches (25cm) could 
cause problems.

Try a different computer, it may not be the cable length but a slow bit 
on the parallel port?
