14 years agoThank you Dave. I looked at the signals:
The JTAG pins look pretty good - overshoot / undershoot is about 200mV. On the starter kit the JTAG signals are buffered with an octal bus switch that is near to the header. The bus switch should be able to cleanup the small bit of ringing. Running the JTAG chain debugger reports that the connection is good and consistent after 1000 IDCODE tests. I could load the software on a different PC (use XP instead of Win7). Is there a reasonable chance that could be an issue? Thank you, Steve
