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.

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.

I want to check, is it possible to program the DueProLogic EPT-4CE6-AF in JTAG mode using just a USB?

I've programmed it before successfully using Active Serial Programming + adding a .pof file, but when using JTAG mode I get "Cant access JTAG chain". I believe I have installed the drivers mentioned in the other post in the forum. Maybe it would work if I got an actual JTAG blaster and used the JTAG connections, but is it possible with just a USB? 

An alternate question, when programming in Active Serial mode, it takes about a minute and loads onto the flash of the board. Is there a way to do something like JTAG programming which if faster for temporary test projects without overriding the flash of the board?

Programming the DueProLogic EPT-4CE6-AF in JTAG mode using just a USB is not possible. You would need a JTAG blaster and use the JTAG connections for programming in JTAG mode.

When programming in Active Serial mode, it loads onto the flash of the board, which takes about a minute. To achieve faster programming for temporary test projects without overriding the flash of the board, you can consider using JTAG programming with a proper JTAG setup.
