NOTE-1: the 10M08 FPGA chip on this board can ONLY be programmed via the JTAG Blaster and the JTAG adapter.

NOTE-2: you can use the "Intel/Altera Quartus Lite" which is free, read more here for info about how to set up the free license.

Needed items

You need to have at hand:

• the special Skudo JTAG adapter (which just allows to physically connect the external USB programmer device to the FPGA JTAG port)

• the FPGA USB programmer device (available via CS/Mouser only for non-EU countries)

• the Skudo Kryptor configuration file (.pof) (any .pof file can be used at any time if you want to load your own program)

• Quartus Prime (the free version and/or just the programmer are good enough)

This is the SKUDO JTAG adapter pictures. Connect the Blaster flat wire as per this picture (note the red wire position compared to the JTAG adapter):

NOTE: connect the power (+5V) and ground (GND) to the first two pins on the Kryptor PCB as the programming won't work if the PCB is not powered. See the picture here for the PCB pin layout.

As soon as you run Quartus Prime you will get this interface, the programming hardware is not plugged yet.

Once you plug the USB programmer device you can then select it as programming device under “hardware setup”.

Once everything is correctly setup then the screen should present the same as the following.

Now it’s time to connect the USB programmer to the Kryptor FPGA via the custom JTAG cable connector. Looking carefully to the 2 long guiding pins, you should insert the connector into the Kryptor PCB board and have a lite push to keep it in place (please note the 7 little POGO pins have springs and will retract slightly). Once the connector is kept in place then you can return to the Quartus software and press the “Auto detect” button.

The pop-up window should show the FPGA model name which should be one of the two following: 10M08DA or 10M16DA. Select it and press OK.
Now the GUI should present this layout and show a little drawing of the selected FPGA chip.

Under the File menu, there is the word “<none>”, you should now double click on it to open the pop-up window related to the configuration file selection.

Now, locate the configuration file (.POF) you got from the SKUDO site, select it and press OPEN. You will then see the following situation.

Under the section “program/configure” select all the checkbox as in the following picture.

You are now ready to program the FPGA chip. Now it is important to keep pressure on the JTAG connector which should have a mechanical connection with the Kryptor PCB board. Once ready, press the “Start” button on the left side and observe the progress green bar on the top right.
After some seconds, the progress bar will reach the 100% and at this point the procedure is properly done and completed. You can then remove the JTAG connector and start using your Kryptor board.

If the bar will give an error then please check the connection between the JTAG connector/cable and the board, and try again.
