			{{Note\| On the Opos93SP_Dev board, prior to remove the flexio-armabus, you'll probably need to:
			* unbind the '''fpga-gpio-leds''' from the GPIOs:
			*:<pre class="apf"> # echo 'fpga-gpio-leds' > /sys/bus/platform/drivers/leds-gpio/unbind</pre>
			* Remove the '''gpio_flexio_armabus''' module:
			*:<pre class="apf"> # rmmod gpio_flexio_armabus</pre>

			=== Configuration ===

			The ''flexio-armabus'' kernel driver will configure the FPGA via SPI as soon as it is loaded.
			Please copy your '''<YOUR_PROJECT>.hex.bin''' to ''/lib/firmware/fpga/bitstream.bin'' on the board and either reboot, or unload and reload the module:

			# rmmod flexio-armabus
			# modprobe flexio-armabus
