5.8 Upgrading CPU Card U1 CPLD
The CPU card U1 upgrade can be performed any time after the V7.5 CPU card firmware has been
loaded into the card.
The U1 firmware image is embedded in the CPU card firmware image and therefore no additional
download from EHX is required.
Upgrade one CPU card at a time and verify correct functionality of the card after the upgrade before
upgrading the second card.
Note – Power must not be lost to the CPU card during the upgrade of the U1 CPLD. The duration of
the device load is approximately 5 seconds, but this will only commence a number of seconds after
the card has been booted. If power is lost during the U1 CPLD upgrade the Xilinx tools method of
upgrade will be required to recover the card. Until this is done the card will not be usable. It is
therefore also especially important to upgrade the U1 CPLD on one CPU card at a time.
Note – Older revisions of CPU card do not support this following centralized upgrade. In order to
establish if a CPU card supports the following upgrade method request a firmware report from EHX. If
the U53 and U1 versions for a CPU card are reported as UNKNOWN then this method of CPLD
upgrade is not supported and the Xilinx tools method of upgrade detailed in this section will need to
be used.
To upgrade a CPU card U1 CPLD device firmware image
1. Set the CPU card DIP switches as follows. This enables CPLD firmware upgrades.
2. Re-insert the CPU card into the matrix.
3. Press and hold the ‘Config’ button on the front of the CPU card.
4. Pin reset the CPU card and wait for 5 seconds.
5. Release the ‘Config’ button. . If the CPLD image requires upgrading this will be performed
and the CPU card will reset on completion to action the image in the CPLD device.
6. When the CPU card initializes (or re-initializes as a result of step 2.) and determines that the
CPLD image is up to date it will output the following message via the LED front panel “CPLD
Upgrades Enabled”.
