LiteX (FPGA)
|
|
============
|
|
|
|
`LiteX <https://github.com/enjoy-digital/litex>`_ is a Python-based System on a Chip (SoC) designer
|
|
for open source supported Field Programmable Gate Array (FPGA) chips. This means that the CPU
|
|
core(s) and peripherals are not defined by the physical chip. Instead, they are loaded as separate
|
|
"gateware". Once this gateware is loaded, CircuitPython can be loaded on top of it to work as
|
|
expected.

|
Installation
|
|
-------------
|
|
|
|
You'll need ``dfu-util`` to install CircuitPython on the Fomu.
|
|
|
|
Make sure the foboot bootloader is updated. Instructions are here: https://github.com/im-tomu/fomu-workshop/blob/master/docs/bootloader.rst
|
|
|
|
Once you've updated the bootloader, you should know how to use ``dfu-util``. It's pretty easy!
|
|
|
|
To install CircuitPython do:
|
|
|
|
.. code-block:: shell
|
|
|
|
dfu-util -D adafruit-circuitpython-fomu-en_US-<version>.dfu
|
|
|
|
It will install and then restart. CIRCUITPY should appear as it usually does and work the same.
