Signal LCC Firmware C7c Update.

Signal LCC Boot fixer:

The Signal LCC boot fixer upgrade will repair an issue that caused the Signal LCC to jump into boot mode if the power supply rise time is too slow. Make a backup of your CDI configuration and then install the boot loader upgrade prior to installing the C7c update. Click here for more information.

Be sure that you are using JMRI version 4.8 or later.

  3. the node is now in boot loader mode -> download the appropriate UPDATE firmware (attached);
  4. toward the end of the download, press and hold the BLUE button;
    4a) should step 4 be skipped, the node starts up with CDI values as they were before, so the event loop restarts;
    4b) in this case, power down the node and press and hold the BLUE button while powering up;
  5. hold the BLUE button for at least 15 seconds, until the GOLD, BLUE and RED led starts to flicker;
  6. release the BLUE button, done!

IMPORTANT NOTICE: Because the CDI now has new CDI items, all existing CDI backup files created with older node firmware (before rev. C2) have become outdated. The C3-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. C3.

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 early versions of 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_C6a_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 C3.

  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-C5' in the Network Tree view, and Software Version: rev-C5 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.
