Hello guys, I am new here but I got the discussion and want to ask!

Do we can program the DueProLogic EPT-4CE6-AF in JTAG mode with USB? 

EPT-4CE6-AF. This can be achieved using specialized programming software and hardware that supports JTAG programming through a USB interface. For example, Xilinx's Impact or Vivado software can be used in conjunction with a USB-JTAG programming cable to program the FPGA in JTAG mode. This allows for convenient and flexible programming of the device using a standard USB connection.

In summary, yes, you can program the DueProLogic EPT-4CE6-AF in JTAG mode using USB. It offers a convenient and accessible method for programming the FPGA on the device.

To program the DueProLogic EPT-4CE6-AF in JTAG mode, you typically need a dedicated JTAG programmer, such as a USB Blaster. Using just a USB connection without the proper JTAG hardware won't work, which is likely why you're encountering the "Can't access JTAG chain" error. The USB connection alone does not provide the necessary interface for JTAG programming.
