I cant establish JTAG communication with this part. nCONFIG always stays low indicating the part never generates\comes out of a Power On Reset which is required for configuration to be possible. Can any let me know what I can try? I have read what I believe are all the applicable ALTERA datasheets, handbooks, and app notes, for which I have my electrical interface implemented accordingly. I have VCC coming up with 50 -100us, and VCCAUX coming up after VCC reaches its final value. I dont know what the heck I may be doing wrong.

Hi, Could you help to check if there is anything that is driving the nConfig pin? The reason is that this signal is input pin.

Hi John, thank you very much for your response. We did already try driving the nCONFIG pin but unfortunately that did not help.

Hi, Could you help to measure using scope on nConfig and nStatus pin? I would like to understand what is the status of the device.
