Honored ContributorOther questions about CPLD reprogramming. :confused:
Where does TCK signal originate? Reading the guide I understand that TCK comes from PC via USB-blaster. If JTAG chain is incomplete, how can I observe TCK waveform with an oscilloscope? How can I apply boundary-scan testing too? Among previous posts I read that CPLD hasn’t to work continuously to be programmed. In my project a DSP provides signals to CPLD inputs. Do you advise me to set these signals to zero? For proper functioning, does Quartus II web edition require internet connection? Is it possible that problems derive from USB port? Suppose that I doubt USB-blaster is damaged. What can I do to receive technical assistance? Thank you very much for your interest. Fabio
