Signal LCC Firmware C2 Update.

Be sure that you are using JMRI version 4.14 or later.

Using Firefox, Google Chrome, or Safari, (NOT Microsoft Edge) download the latest firmware files,  SignalLCC_C2_UPDATE.hex to your local machine.

Note that this upgrade will not disturb your existing configuration data which is stored in a different NVR chip.


C2 Updates Include:

IMPORTANT NOTICE: Because the CDI now uses different names for many variables, all existing CDI backup files created with older node firmware (before rev. C2) have become outdated. The C2-UPDATE doesn't affect your existing configuration at all, so it is strongly advised to create a new backup file immediately after updating to rev. C2.

Firmware Update process:

Note: This version of the Signal LCC update loads both the new firmware and the new CDI at the same time. This means that you will no longer need to do a dual upgrade as was previously required for the Signal LCC.

When ever an update to your Signal LCC firmware is needed, a program such as "Firmware Update" in JMRI version 4.14 or later is required. Download the latest firmware files to your local JMRI User Files folder or someplace where you can easily access it.

To enter Firmware update mode:

  1. Start JMRI and select "LCC".

  2. Select ‘Firmware Update’ from the LCC drop down list.
Select LCC Firmware Update
  1. Click ‘Select’ to pick a firmware file.

  2. From the file menu, select: 'SignalLCC_C2_UPDATE.hex' or the latest upgrade available.
  3. Select your 'Target Node ID'.
  4. Optionally you may check the ‘Lock Node’ check box to take the node off line during the upgrade.
  5. Click the 'Load' button to initiate the download to Signal LCC revision C2.

    Target
  1. Wait until 'updating device firmware..' progress bar is complete and shows 'Operation Complete'.
  2. Once the operation is complete, open the OpenLCB Network Tree window. (LCC-Configure Nodes) Then click on 'Open Configuration dialog for the just updated node.
  3. The updated node should now show 'Mod: Signal-LCC' and 'Software Version: rev-C2' in the Network Tree view, and Software Version: rev-C2 in the CDI view.
  4. Any errors will be shown in the lower window ticker tape display.

Normally upgrades to the Signal LCC node may be accomplished without actually accessing the board itself. However if the node does not automatically enter boot mode and start the upgrade it may be forced into boot mode by un-powering it, then holding down the ‘Gold’ button as you power it up again. The gold LED should start flashing to indicate that it is in forced boot mode. This will also likely be required after a failed upgrade attempt.
