Chapter 4. USB Base Board Firmware Update
4.1
INTRODUCTION
The Microchip Technology Serial Memory Evaluation kit has a built-in ability to update
the USB Base Board using a sequence of steps outlined by GUI or using the Atmel
FL
exible
I
n-system
P
rogramming (FLIP) software.
4.2
USING THE GUI TO UPDATE THE FIRMWARE
If the GUI detects the firmware needs to be updated, it will prompt the user to update
the firmware using a sequence of steps outlined on the screen. Please follow the steps
on the screen and the firmware will be updated. Note that once the USB Base Board
firmware has been updated, it is recommended that the customer disconnect the USB
Base Board from the PC and reconnect (as specified by the GUI) before restarting the
GUI.
4.3
USING THE FLIP SOFTWARE TO UPDATE THE FIRMWARE
If the user chooses to update the firmware using the more manual FLIP software
process, first plug in the USB Base Board into a USB port without the SPI Socket Board
connected. The PC will recognize the USB Base Board as “SPI Evaluation Kit” in the
PC’s Devices and Printers
window from the Control Panel, if there is firmware already
loaded in the USB Base Board (
). Note that the COM port numeration may
change based on the user’s PC.

Once the USB Base Board is plugged in and recognized by the PC, the user should
enable DFU mode on the USB Base Board. DFU mode is enabled by a specific
sequence of
HWB
and
RESET
buttons. Refer to
for locations of the
HWB
and
RESET
buttons.
Note:
Both USB Base Board firmware update modes use Atmel FLIP software
and, therefore, it must be installed on the user's PC in order to perform
either firmware update process.
Note:
The USB Base Board must be reset or disconnected after the firmware
update in order to complete the process.
