Update Amplifier Firmware

Some software updates will require amplifier firmware to be updated.

To update amplifier firmware:

First close the Espion software, then navigate to the Windows Start Menu and search for "LPC2000 Flash Utility". You will see the following pop-up window; adjust the settings to match.

1 Place a check next to "Use DTR/RTS for Reset and Boot Loader Selection"

2 Place a check next to "Execute Code After Upload"

3 Change XTAL Freq. [kHz] to 12000

4 Browse for the latest firmware version file.

          Look in Computer > C Drive > Multifocal > Amplifier Flash > ARM_32BIT_V6_8.hex

          If you do not see the file present in the Amplifier Flash folder, download it from this article.

5 Change Use Baud Rate to 38400

6 Change Connected Port to COM4 (sometimes COM 5); use trial and error

7 Click Upload to Flash

This query is complete once the blue bar stretches all the way across the bottom of the window. At that point you are free to close this pop-up window and proceed with normal usage.

In case you run into the "Cannot communicate with Test Board!" error message.  Close LPC2000, and open Espion software.  Run any protocol, for instance the standard ffERG protocol.  In the runtime window, click Preview button and allow amplifier to sample for 5 seconds.  Then click stop.  Exit, don't save, and close Espion software.  Open LPC2000 and try again to install firmware.
