Firmware

In order to use this device, the sigrok-firmware-fx2lafw (>= 0.1.4) firmware is required.

The firmware was originally written by Jochen Hoenicke (see README for details), thanks a lot!

Note: The firmware is not flashed into the device permanently! You only need to make it available in the usual place where libsigrok looks for firmware files, it will be used automatically (and "uploaded" to the Cypress FX2's SRAM every time you attach the device to a USB port).
