New ContributorThanks for the reply. I have the question.
1. I am sure that the JTAGEN is pulled high,
2. when you mentioned "lose JTAG access", do you mean momentarily ? or you mean permanently ?
The symptom I have encountered is that there is no hardware modification and yet, I lost the JTAG access. After replacing the FPGA, the USB blaster works and I can program the FPGA again.
