Correcting a Failed Upgrading Procedure
Firmware upgrades may fail in the event of network interruptions,
power failures, or if too much data is uploaded to the NEO module.
Often, uploads of too much data can occur for one of the following
reasons:
•
The boot file (typically vxWorks.lzs ) was accidentally uploaded
during the fl0 procedure, instead of the boot procedure.
• Files were sent to the wrong NEO module.
• The particular hardware version of the module requires only some
(but not all) of the available fl0 files.
• The upgrade .zip file was mistakenly sent to the module.
All of these problems can be corrected by re-installing the firmware
while in a fail-safe mode, as described in the following pages. When
you are performing this procedure, check the appropriate readme file to
confirm which files are needed. Use care to ensure that you upload the
correct files to the intended module.
Setting the Module to Fail-Safe Loader Mode
Follow these steps to set a NEO module to the fail-safe loader mode:
1. Remove the affected module from the NEO frame.
2. Press the
Nav switch down while simultaneously pressing both the
Escape and Enter buttons.
3. While still pressing the buttons and the navigation switch, reinsert
the module into the frame and hold for approximately three seconds
until the display on the module reads
Offline-H (or Offline-L )
Upload Required .
Upgrading the Firmware in Fail-Safe Mode
Follow these steps to upgrade the firmware in the fail-safe mode:
1. Download the most recent appropriate upgrade package from the
Leitch Web site or from your CD-ROM, and then unzip the upgrade
package.
Note
To successfully upgrade the
firmware, you must follow these
steps in the exact sequence
described.
