For download, you will need the current firmware and the manual
. The hardware version is shown on the analyzer startup screen.
Download is performed using the FLIP program from the Atmel Corporation. If you are unable to download the program directly, you will find the newest version of FLIP on the firm's website at Atmel. Use of the FLIP program is described in the download manual. Use only FW version for your HW model!
