How to upgrade Field Programmable Device (FPD) on Cisco IOS-XR

How to upgrade Field Programmable Device (FPD) on Cisco IOS XRAs per Cisco official documentation, the definition of FPD as follows:
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.1. Use the command ‘show hw-module’ to provide information about the FPD
admin show hw-module fpd location all
Sample:RP/0/RSP0/CPU0:CISCO-A9K#admin show hw-module fpd location all

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.

Note: As you can see those FANs and RSPs no longer require upgrade as from the column Upg/Dng? are stated as “No”, while those PWR-6KW power supply are stated as “Yes”.
From the message above, it was mentioned that upgrade can be accomplished using the command
“admin> upgrade hw-module fpd <fpd> location <loc>”
It can be upgraded by using this command:

upgrade hw-module fpd all location all

This is to upgrade all the fpd of all the linecards inserted in the router. But not always works as some fpd need to specify the location.

RP/0/RSP0/CPU0:CISCO-A9K(admin)#upgrade hw-module fpd all location all

This can take some time for a full chassis.
Ensure that system is not power cycled during the upgrades.
Please consult the documentation for more information.

***** 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

No fpd on location 0/RSP0/CPU0 need upgrade at this time.
No fpd on location 0/RSP1/CPU0 need upgrade at this time.
No fpd on location 0/0/CPU0 need upgrade at this time.
No fpd on location 0/1/CPU0 need upgrade at this time.
No fpd on location 0/2/CPU0 need upgrade at this time.

Example:
RP/0/RSP0/CPU0:CISCO-A9K(admin)#upgrade hw-module fpd all location 0/PS0/M1/SP

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.
