PicoSoC demo
~~~~~~~~~~~~
This example features a picorv32 soft CPU and a SoC based on it. To build the
picosoc example, run the following commands:
.. code-block:: bash
:name: example-picosoc-basys3-group
TARGET="basys3" make -C picosoc_demo
Now you can upload the design with:
.. code-block:: bash
openocd -f ${INSTALL_DIR}/conda/share/openocd/scripts/board/digilent_arty.cfg -c "init; pld load 0 top.bit; exit"
You should observe the following line in the OpenOCD output:
.. code-block::
Info : JTAG tap: xc7.tap tap/device found: 0x0362d093 (mfg: 0x049 (Xilinx), part: 0x362d, ver: 0x0)
The UART output should look as follows:
.. code-block::
Terminal ready

.. note::
PicoSoC uses baud rate of ``460800`` by default.
The board's LED should blink at a regular rate from left to the right
