As per Cisco official site definition of FPD:
An FPD refers to any programmable hardware device on a router, which includes a Field Programmable Gate Array (FPGA) and Read Only Memory Monitor (ROMMON). Cisco IOS® XR routers use a number of FPDs that are crucial for the function of route processors, line cards, shared port adapters (SPAs), SPA Interface Processors (SIPs), and fan trays.
Sample of upgrading fpd in ASR9000 running in IOS-XR. Linecard used is 24x10GE Tomahawk linecard.
A. Check first the linecards installed

B. See if need to upgrade , it will indicate Yes if need to upgrade.
Show it using this command "admin show hw-module fpd location all"
It will tell below that one of the FPDs need an upgrade. Type "yes" to reload"

NOTES:
1. One or more FPD needs an upgrade. This can be accomplished
using the "admin> upgrade hw-module fpd <fpd> location <loc>" CLI.
2. ^ One or more FPD will be intentionally skipped from upgrade using CLI with option "all" or during "Auto fpd".
It can be upgraded only using the "admin> upgrade hw-module fpd <fpd> location <loc>" CLI with exact location.
C. Upgrade the FPD using the command "admin> upgrade hw-module fpd <fpd> location <loc>"

***** UPGRADE WARNING MESSAGE: *****
* This upgrade operation has a maximum timout of 90 minutes. *
* If you are executing the cmd for one specific location and *
* card in that location reloads or goes down for some reason *
* you can press CTRL-C to get back the RP's prompt. *
* If you are executing the cmd for _all_ locations and a node *
* reloads or is down please allow other nodes to finish the *
* upgrade process before pressing CTRL-C. *
% RELOAD REMINDER:
- The upgrade operation of the target module will not interrupt its normal
operation. However, for the changes to take effect, the target module
will need to be manually reloaded after the upgrade operation. This can
be accomplished with the use of "hw-module <target> reload" command.
- If automatic reload operation is desired after the upgrade, please use
the "reload" option at the end of the upgrade command.
- The output of "show hw-module fpd location" command will not display
correct version information after the upgrade if the target module is
not reloaded.
NOTE: Chassis CLI will not be accessible while upgrade is in progress.
Continue ? [no]: yes
FPD upgrade in progress on some hardware, reload/configuration change
on those is not recommended as it might cause HW programming failure
and result in RMA of the hardware.

WARNING: This will take the requested node out of service.
Do you wish to continue?[confirm(y/n)]y

E. Verify again after reload. "No" means no longer need to upgrade , and it was successfully upgraded.
