Efinix Trion JTAG Programmer and Evaluation Board

This board implements a JTAG programmer that can be used with the efinity software to access efinix FPGAs via JTAG.

The board also hosts a Trion T8Q144 device (pin-compatible with the more loaded T20Q144 which could be used as an alternative), ULPI and full-speed PHYs and a bunch of LEDs/GPIOs.

I have used this board successfully to exercise the mecatica-usb with trion devices.

The programmer is connected to the trion's JTAG port with a flat ribbon cable which makes it possible to use the PCB as a programmer for other boards with an Efinix FPGA.

Programmer-only Mode

It is possible to partially load the board if you are only looking for a programmer.

  • load everything on the FT-USB-JTAG sheet
  • load the 3V3 converter (U12) and associated components on the Power sheet. You can omit U6 and everything associated with it.
  • However, make sure you do load R56 (may be a zero-Ohm jumper if U6 is omitted) in order to enable the 3V3 converter.
