Programming a development board
|
|
|
|
|
===============================
|
|
|
|
|
|
|
|
|
|
Just simply replace ``my_fpga_board`` with any FPGA board from :ref:`compatibility:boards`
|
|
|
|
|
(or ``openFPGALoader --list-boards``) in any of the two commands below, depending on if you want to program the volatile
|
|
|
|
|
part of your FPGA (faster but not persistent) or the flash part of your FPGA (slower but persistent):
|
|
|
|
|
|
|
|
|
|
.. code-block:: bash
|
|
|
|
|
|
|
|
|
|
openFPGALoader -b my_fpga_board my_bitstream.bit # Program to SRAM
|
|
|
|
|
openFPGALoader -b my_fpga_board -f my_bitstream.bit # Program to flash
|
|
|
|
|
|
|
|
|
|
.. NOTE::
|
|
|
|
|
When a bitstream file is compatible with both memory load and FLASH write, the default behavior is to load bitstream
|
|
|
|
|
in memory.
|
|
|
|
|
|
|
|
|
|
Programming an "standalone" FPGA
|
|
|
|
|
================================
|
|
|
|
|
|
|
|
|
|
If your FPGA doesn't come with a built-in programmer or if you prefer to use an external cable, you can specify a cable
|
|
|
|
|
to use from :ref:`compatibility:cables` (or ``openFPGALoader --list-cables``):
|
|
|
|
|
|
|
|
|
|
.. code-block:: bash
|
|
|
|
|
|
|
|
|
|
openFPGALoader -c my_cable my_bitstream.bit # Program to SRAM
|
|
|
|
|
openFPGALoader -c my_cable -f my_bitstream.bit # Program to flash
|
|
|
|
|
|
|
|
|
|
.. NOTE::
|
|
|
|
|
For some cable (like digilent adapters) signals from the converter are not just directly to the FPGA.
|
|
|
|
|
For this case, the ``-c`` must be added.
|
|
|
|
|
|
|
|
|
|
.. HINT::
|
|
|
|
|
FTDI/FTDI-compatible cable users: the ``-d`` option lets you specify a specific FTDI device:
|
|
|
|
|
|
|
|
|
|
.. code-block:: bash
|
|
|
|
|
|
|
|
|
|
openFPGALoader -d /dev/ttyUSBX
|
|
|
|
|
|
|
|
|
|
When the ``-d`` option is not provided, openFPGALoader will opens the first FTDI adapter it finds.
|
|
|
|
|
Therefore it is preferable to use this flag if your computer is connected to multiple FTDI devices.
|
