Building gb-beagleplay Kernel Module
**************************************
`gb-beagleplay` is still not merged upstream and thus needs to be built seperately. This should not be required in the future.
#. Disable bcfserial driver. Add `module_blacklist=bcfserial` to kernel parameters at `/boot/firmware/extlinux/extlinux.conf` (line 3).
#. Reboot

Run Demo
*********
#. Connect beagleconnect.
#. See shell output using `tio`
.. code-block:: bash

#. Press reset button on beagleconnect freedom.
#. Verify that greybus is working by checking the `tio` output. It should look as follows:
