Firmware Updates for C7042

WARNING: It appears that Hornby have recently changed the components or configuration of the C7042 powerbase. Please do not upgrade the firmware of recently bought C7042 powerbases while this warning remains. I will try and figure out what they have done and resolve the issue. If you proceed, despite this warning, you do so entirely at your own risk and are likely to 'brick' your powerbase. You have been warned!

Before you can upgrade your powerbase, you need to download and install the firmware update tool (v1.4) from here.

The firmware update tool is a Microsoft Windows application that requires a minimum of .net v3.5 installed on your machine. If you are using SSDC, then you will already have this installed.

Next, connect your powerbase to your PC with your serial/USB cable and start the firmware update tool.

  1. Select COM Port (the same one that you use for SSDC)
  2. Select Hex File and browse to the firmware file that you have just downloaded
  3. Turn on Powerbase with the top button pressed (shown in the photo below). This makes it ready to accept a new firmware
  4. Press Program (you have plenty of time, about 15 seconds or so)

Starting the powerbase in upgrade mode

If all is ok you will see status information scrolling in the bottom window, and the LEDs on the powerbase will cycle up and down. The status will then stop scrolling and show "Done".

Unplug the power from the powerbase, and then plug the power in again. If you connect the powerbase display you will see the new build number on the display at startup.

Troubleshooting

There are known issues when using certain powerbase to USB cables. Should the firmware tool report an error there is no need to worry. Your powerbase will still have the original firmware loaded. If your powerbase to USB cable is made of two parts (i.e. powerbase to serial + serial to USB), you should be able to separate the two cable parts and then connect the serial connector to a PC serial port. This approach is likely to be more successful.
