No problem. We will be working with the FLASH. Here are the steps I just preformed.
- Select the Chip (ATMEGA16U2)
- Select the communications media (USB) and click Open in the dialog box
- Click Read Memory from Device (GREEN arrow pointing out of the chip)
- Load .hex file into buffer (Arduino-COMBINED-dfu-usbserial-atmega16u2-Uno-Rev3.hex)
(Screen show look like the attached screenshot) - Click in the Operations Flow pane
- Upon no errors, close FLIP, disconnect and reconnect Uno and Upload a sketch like blink.
