Yes, I am using a Sophia Systems EJ-Debug (JTAG based emulator). Apparently
it makes use of the JTAG capabilities of the PXA255 through some hardware
"stuff" (I'm not a hardware guy! :-) The "WatchPoint" debugger software is
their interface to it. We hoped to just plug it in the JTAG header and
start debugging. I was able to get through the initial startup code without
a debugger, but when it comes to figuring out the download protocol I needed
a little more than that to be the most effiecient.
