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
