Linux LiteX demo
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
This example design features a Linux-capable SoC based around VexRiscv soft CPU.
|
|
It also includes DDR and Ethernet controllers.
|
|
To build the litex example, run the following commands:
|
|
|
|
To build the linux-litex-demo example, first re-navigate to the directory that contains examples for Xilinx 7-Series
|
|
FPGAs.
|
|
Then, depending on your hardware, run:
|
|
|
|
.. code-block:: bash
|
|
:name: example-litex-a35t-group
|
|
|
|
TARGET="arty_35" make -C linux_litex_demo
|
|
|
|
.. code-block:: bash
|
|
:name: example-litex-a100t-group
|
|
|
|
TARGET="arty_100" make -C linux_litex_demo
|
|
|
|
At completion, the bitstreams are located in the build directory:
|
|
|
|
.. code-block:: bash
|
|
|
|
linux_litex_demo/build/<board>
|
|
|
|
Now you can upload the design with:
|
|
|
|
.. code-block:: bash
|
|
|
|
TARGET="<board type>" make download -C linux_litex_demo
|
|
|
|
.. note::
|
|
|
|
The LiteX design is provided with an Ethernet module that uses the ``192.168.100.100/24``
|
|
IPv4 address that needs to be set on your network interface.
|
|
|
|
You may find these information useful to correctly setup the network interface: `timvideos/litex-buildenv/wiki/Networking <https://github.com/timvideos/litex-buildenv/wiki/Networking>`__.
|
|
|
|
You should observe the following line in the OpenOCD output:
|
|
|
|
.. code-block:: bash
|
|
|
|
Info : JTAG tap: xc7.tap tap/device found: 0x0362d093 (mfg: 0x049 (Xilinx), part: 0x362d, ver: 0x0)
|
|
|
|
In the ``picocom`` terminal, you should observe the following output:

|
|
|
|
Additionally, two LED's on the board should be turned on
