Honored Contributor --- Quote Start --- Yes I allready did that, it's a Mezzanine board normally tested in a system. But also possible to test it seperately. It's not only the TDO but I think the complete TAP is disappeared after erase with quartus. I tried to put the device in extest but nothing happened. The only thing I can think of is that the erase action is writing something in the private registers ( see the last lines from the ep2s60 bsdl) : "The following private instructions must not be used as they"& "may render the device inoperable:"& " "& " 1100010000 "& " 0011001001 "& " 0000101001 "& " 0000010000 "& " "& "Customer should take precautions not to invoke these instructions"& "at any time. Contact Altera Applications for further assistance."; --- Quote End --- Hi, sorry I'm not a JTAG expert. Maybe you should contact the altera Application guy's. Kind regards GPK
