Hello,


Is this the first time you see JTAG error on this board, or is it working properly previously?

JTAG dont need MSEL setting as JTAG will override MSEL setting.


Items I need you to check:

  1. USB Blaster installation. Go to Device Manager > Check USB Blaster status
  2. Open Quartus Programmer, click Auto-detect, can you see any device detected?
  3. Using oscilloscope, please provide scopeshot for nSTATUS, CONF_DONE, nCONFIG when you start programming the FPGA.


regards,
