Firmware Upgrade
Instructions
4.1 Introduction
The following is a short tutorial on how to upgrade the FireFly-1A GPSDO firmware. Please follow
the instructions in-order to prevent corrupting the FireFly-1A Flash, which may require reflashing at
the factory.
With some practice, the entire Flash upgrade can be done in less than one minute, even though the
following seems like a fairly long list of instructions.
4.2 ISP Flash Loader Utility installation
There are two Flash loader utilities available to upgrade the FireFly-1A firmware. You can download
the Philips LPC2000 utility from the Jackson Labs Technologies, Inc. website under the Support tab:

The Flash Magic utility is available for download on the Flash Magic website:

4.2.1 Philips LPC2000 Flash Utility
The first is the Philips LPC2000 utility version 2.2.3. Please note that some computers are known to
be incompatible with the LPC2000 flash utility. Preliminary investigations show Windows Media
Center and/or Centrino vPro processor systems to create download difficulties. Please use a different
computer if you experience problems such as the download breaking up in the middle of the transfer.
Or, alternatively, you may use the Flash Magic programming tool.
Please ensure that you have at least version 2.2.3 of the LPC2100 flash utility installed. Earlier
versions may not recognize the LPC2138 processor used on the FireFly-1A boards.
4.2.2 Flash Magic Flash Programming Utility
The second utility is the Flash Magic tool available on the Flash Magic website:
