Firant and Xyloni boards (efinix trion T8)
==========================================

``.hex`` file is the default format generated by *Efinity IDE*, so nothing special must be done to generates this file.

*openFPGALoader* supports only active mode (SPI) (*JTAG* is WIP).

hex file load
-------------

.. code-block:: bash

    openFPGALoader -b fireant /somewhere/project/outflow/*.hex

or, for xyloni board

.. code-block:: bash

    openFPGALoader -b xyloni_spi /somewhere/project/outflow/*.hex

Since openFPGALoader access the flash directly in SPI mode the ``-b fireant``, ``-b xyloni_spi`` is required (no
autodetection possible).

Trion and Titanium JTAG usage
==========================================

*openFPGALoader* supports loading to RAM and SPI Flash with JTAG

Tested with J-Link BASE

bin file load
-------------

.. code-block:: bash

    openFPGALoader --cable jlink_base -m  /somewhere/project/outflow/*.bin

hex file flash
--------------

Example for ti60f225.
NOTE: JTAG chains with more than one device (eg --index-chain) are currently not supported for writing to SPI flash

.. code-block:: bash

    openFPGALoader --cable jlink_base --fpga-part ti60f225 -f  /somewhere/project/outflow/*.hex
