3-16 Chapter 3: Maintenance
Unlike the firmware 3.2.0, 3.4.0 CBS cannot be downgraded as low as
the CBS hardware can allow in the previous chart. For example, the
original hardware release 3.2 CBS can be downgraded from firmware
3.4.0 to 3.2.0. However, ftpdl.exe reports an error and the CBS remains
unaffected if a revised hardware release 3.2 CBS is downgraded from
firmware 3.4.0 to 3.2.0. If TFTP bootload feature is used to downgrade
the firmware, the CBS ignores the bootload request and remains
unaffected.
Updating the Firmware
Periodically updates may be required to add enhancements or correct
problems in the CBS firmware.
Upgrade all CBS firmware to the latest version available. The latest
firmware release can be found at www.ncr.comÆSupport ÆDrivers
and PatchesÆRetail Support FilesÆRealPrice Support Files.
Note: Check to make sure that the customer does not have a special
firmware version requirement.
Caution: Some customers may not allow firmware to be installed
until it has been integration tested.
The 7730 Firmware Management System – “Firmware Bootloader” –
(released with firmware version 3.3.4) facilitates firmware updates to
the 7730 Communications Base Station (CBS). The Firmware
Bootloader consists of software components that reside on both the
RealPrice System Server and 7730 CBS units.
Upgrading firmware from 3.2.x and earlier to 3.3.4 requires upgrading
to firmware version 3.3.4 first using the method (ftpdl) described in the
previous section “Updating CBS's Firmware Image (ftpdl)”.
The Firmware Bootloader supports:
• Simultaneous firmware update to multiple CBS units
• CBS recovery following application block firmware corruption
• Diagnostic features to support flash update failure troubleshooting
