Figure 22: main window after the FPGA firmware files have been loaded

To update the MCU firmware it is necessary to specify a single file, named the MCU file. After
pressing the

Load MCU file

button the modal dialog of

Figure 23: dialog used to locate the MCU

firmware file

will be displayed, asking to specify the MCU file.
