You'll require programming software that supports your microcontroller or FPGA, depending on the intended device. While some microcontroller makers may work with more general tools, others might come with their own programming tools.

You can program the DueProLogic EPT-4CE6-AF using either the JTAG or Active Serial modes. The board can be programmed in JTAG mode with a USB connection, but a JTAG blaster or programmer is necessary. For JTAG programming, the USB connection is insufficient on its own.

A JTAG blaster or programmer can be connected to the board's JTAG header in order to program it in JTAG mode. In this way, you can program the board by accessing the JTAG chain.

Concerning your second inquiry, the answer is that Active Serial programming usually takes longer than JTAG programming. But typically, when programming a board using JTAG, you have to bypass its flash memory. Use a USB bootloader or a faster data transfer interface like USB 3.0 or Ethernet if you want to load temporary test projects fast without changing the flash memory. Another option is to use a different programming method. You could swiftly upload your test projects to the board using these techniques.

You can load bitstream files onto the flash memory without erasing the existing content using tools like OpenOCD or Xilinx Vivado.

programming via JTAG typically requires a JTAG adapter or programmer that connects to the target device's JTAG port, and then this adapter is connected to a computer for programming and debugging.

Numerous FPGAs enable loading a configuration into internal RAM, operational until the next power cycle. This facilitates file puma swift testing and prototyping without necessitating writes to flash memory, offering a convenient approach for temporary configurations.

You are having trouble setting the DueProLogic EPT-4CE6-AF in JTAG mode with just a USB, it looks like. "Can't access JTAG chain" is an error message that means there is a problem with the JTAG connection or drivers. Even though you installed the drivers stated, you might still want to check the connection or give it a try with a JTAG blaster.

In answer to your question about how to speed up programming for short-term test projects without changing the board's flash, JTAG programming is usually faster than Active Serial mode. But remember that if you want to use JTAG, you might need extra gear and connections.

Make sure you have the right drivers installed and check the JTAG link when you are programming the DueProLogic EPT-4CE6-AF in JTAG mode with just a USB. If you use a specialized JTAG blaster, the problem might go away. In terms of writing speed, JTAG is usually faster, which means it can be used for quick tests without overriding the flash. In the same way, if you want to take a fancy trip, you might want to book a limousine service in France. They will make your trip easy and stylish. Picking the right tools and services improves the end result, just like picking the right computer language.

Connect the USB JTAG adapter to your computer via USB and to the JTAG interface on your target device. Ensure that the connections are correct and secure.

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.
