``.jed`` file is the default format generated by *Lattice Diamond*, so nothing special must be done to generates this
|
||
|
|
file.
|

|
|
|

|
|
File load:
|

|
|
|

.. code-block:: bash
|

|
|
|
||
|
|
openFPGALoader [-b yourboard] [--flash-sector CFG0] impl1/*.jed
|
||
|
|
|
||
|
|
where ``yourboard`` may be:
|
||
|
|
|
||
|
|
* ``machX02EVN``
|
||
|
|
* ``machX03EVN``
|
||
|
|
* ``machXO3SK``
|
||
|
|
|
||
|
|
and where ``--flash-sector CFG0`` is needed for the MachXO3D Breakout Board.
|
||
|
|
|
||
|
|
``.bit`` may also be used for *machXO2*

To generates ``.bit`` file *Bitstream file* must be checked under *Exports Files* in *Lattice Diamond* left panel.

|

|
``.bin`` is the default format generated by *nextpnr*, so nothing special must be done.
|
||
|
|
|
||
|
|
Since most ice40 boards uses the same pinout between *FTDI* and *SPI flash* a generic *ice40_generic* board is provided.
|
||
|
|
|
||
|
|
For the specific case of the *iCE40HXXK-EVB* where no onboard programmer is present, please use this:

Bin file load:

.. code-block:: bash

||
|
|
|
||
|
|
openFPGALoader -b ice40_generic /somewhere/*.bin
|
||
|
|
|
||
|
|
Since it's a direct access to the flash (SPI) the ``-b`` option is required.

By default, openFPGALoader loads bitstream in memory, so the ``-m`` argument is optional.

SPI Flash write is not supported for ECP3 family.
