Hi Sameer,
 

Auto Detect showing the chain TDI > 5CEFA7 >5M2210Z > TDO confirms that the JTAG connection is working. Therefore, the USB-Blaster II and JTAG cable path are likely OK.


Since the same error occurs with the official example .sof file, default DIP switch settings, and no external cards connected, this is unlikely to be caused by your LED design or the .sof file.


Please check the following:

  • Confirm the FPGA marking on the board is 5CEFA7F31I7N.
  • Use the supplied board power adapter and make sure the board power LEDs are normal.
  • If available, measure nSTATUS and CONF_DONE during programming. nSTATUS should remain high after configuration starts, and CONF_DONE should go high when configuration completes.
  • Try the board test software or factory design to check whether the board can run any known-good design.

If CONF_DONE remains low while using the official example .sof, the issue is most likely related to the board power or configuration circuitry, not the JTAG connection. In this case, please contact the board supplier or distributor for board-level support or replacement.

Fakhrul
