Upgrading Field-Programmable Hardware Devices for Cisco 1000 Series ISRs

 Cisco IOS XE Fuji 16.8.1 Release

In Cisco IOS XE Fuji 16.8.1 Release, support for upgrading field-programmable hardware devices was introduced for the Cisco 1000 Series ISRs.

The following commands were introduced: upgrade hw-programmable, show hw-programmable, show upgrade hw-programmable progress, show upgrade hw-programmable file.

Upgrading Field-Programmable Hardware Devices Overview

The hardware-programmable firmware is upgraded when Cisco 1000 Series ISR contains an incompatible version of the hardware-programmable firmware. To do this upgrade, a hardware-programmable firmware package is released to customers.

Generally, an upgrade is necessary only when a system message indicates one of the field-programmable devices on the Cisco 1000 Series ISR needs an upgrade, or a Cisco technical support representative suggests an upgrade.

From Cisco IOS XE Fuji 16.8.1 Release onwards, you must upgrade the CPLD firmware to support the incompatible versions of the firmware on the Cisco 1000 Series ISR. For upgrade procedures, see the CPLD Field Programmable Upgrade section.


Caution

Do not power down the router during the field-programmable upgrade. Although, the Cisco 1000 Series ISR should be able to recover from most interruptions during the upgrade, certain scenarios may cause unpredictable problems.

Displaying the CPLD Version

If you receive an error message indicating that the device needs an upgrade, and you have an incompatible CPLD version on the device, use the show platform command to display the status of your active Cisco 1000 Series ISR. The following example shows the output of the show platform command on a Cisco ISR 1000 Series Router:

CPLD Field-Programmable Upgrade, Cisco IOS XE Fuji 16.8.1 Release

This section covers the following topics:

CPLD Field-Programmable Upgrade Overview

CPLD field-programmable upgrade can be performed on a need basis to address any specific issues with the hardware-programmable devices.The subsequent sections describe how to upgrade the Cisco 1000 Series ISRs.

To determine if one of the components has an incompatible CPLD version, use the show platform command.

From Cisco IOS XE Fuji 16.8.1 Release onwards, a hardware-programmable package is released to customers whose devices require a CPLD upgrade.

Downloading the Hardware-Programmable Firmware Package

To download the hardware programmable firmware package from Cisco.com, perform these steps:

Procedure

Step 1

Log in to the Download Software page https://software.cisco.com/download/navigator.html.

Step 2

From the Select a Software Product Category area, select > Routers > Branch Routers > Cisco 1000 Series Integrated Services Routers, and select the appropriate router from the list.

Step 3

From the Select a Software Type area select IOS XE Hardware Programmable Devices.

Step 4

Click Download or Add to Cart the IOS XE Software hardware programmable firmware package and follow the prompts.

Note 
A CPLD upgrade is necessary only when a system message indicates that the Cisco 1000 Series ISR needs an upgrade. Cisco 1000 Series ISRs are shipped with Cisco IOS XE 16.8(1r)S1 image pre-installed and that ROMMON upgrade is necessary only starting with Cisco IOS XE 16.8.1 Release.

Upgrading an Active Cisco 1000 Series ISRs

You can upgrade the CPLD firmware on Cisco 1000 Series ISRs using the upgrade hw-programmable command. The CPLD upgrade can take up to ten minutes for each component. You can perform the upgrade on the Cisco 1000 Series ISRs any time as long as you can access the privileged EXEC mode prompt on the router.

To upgrade a Cisco 1000 Series ISRs, perform these steps:

Procedure

Step 1

Cold boot the active Cisco 1000 Series ISR.
Step 2

Copy the hardware-programmable upgrade package to your bootflash:

Example:


copy tftp:/...isr-hw-programmables.03.13.00.S.154-3.S-ext.SPA.pkg bootflash
Step 3

Run the hw-programmable cpld filename command from the EXEC mode:

Example:


Router#upgrade hw-programmable cpld filename bootflash:isr-hw-programmables.03.13.00.S.154-3.S-ext.SPA.pkg R0
Step 4

If you are using Cisco IOS XE 16.8.1 Release or later, then skip to Step 5. At the system prompt, press Enter to start the upgrade:

Example:


Upgrade CPLD on Route-Processor 0 from current version 13041228 to 14061635 [Press Enter to confirm] 
This command could take up to 10 minutes, please wait and do not power-cycle the chassis or the card. Otherwise, hardware may be unrecoverable. It is recommended that all cards are running the same version IOS-XE software prior to the upgrade. At the end of upgrade you will be asked to reload the chassis. [Press Enter to confirm] 
  
Upgrade cpld hw-programmable on Route-Processor 0 
The cpld has been successfully upgraded on Route-Processor/0. 
PLEASE RELOAD THE CHASSIS NOW.

Field-Programmable Hardware Device Commands

You can use the following field-programmable commands to perform a CPLD upgrade, display the package file version, or display progress during the upgrade:

  • upgrade hw-programmable —Performs a CPLD upgrade on a Cisco ISR 1000 Series Router.

  • show hw-programmable —Displays the current CPLD or FPGA version in a particular line card.

  • show upgrade hw-programmable file— Displays the names and versions of individual files in the hardware-programmable package file in a Cisco 1000 Series ISR.

For command syntax and detailed information, see the Cisco IOS Interface and Hardware Component Command Reference.

ROMMON Overview

The ROMMON on an Cisco 1000 Series ISR must be upgraded if a system message on the router indicates that the ROMMON on the router requires an upgrade, or a Cisco technical support representative suggests a ROMMON upgrade.

The ROM Monitor is a bootstrap program that initializes the hardware and boots the Cisco IOS XE software when you power on or reload a router. When you connect a terminal to the router that is in ROM Monitor mode, the ROM Monitor command-line interface (CLI) prompt is displayed.

Checking the Current ROMMON Version

If you are unsure whether a ROMMON upgrade is required, use the show rom-monitor command or the show platform command.

Upgrading the ROMMON for a Cisco 1000 Series ISRs

To upgrade the ROMMON, perform these steps:

Procedure

Step 1

(Optional) To display the current ROMMON version at the IOS prompt, use the following command:

Router# show rom-monitor R0
System Bootstrap, Version 16.8(1r), RELEASE SOFTWARE
Copyright (c) 1994-2018 by cisco Systems, Inc.
Step 2

From a computer, copy the ROMMON pkg file onto a USB Flash drive and insert it into the usb0: slot, or download the ROMMON pkg file to the bootflash: using the IOS ‘copy tftp:’ command.

Step 3

(Optional) Use the IOS ‘verify /md5 <filesystem>:<pkg filename>’ command to verify the MD5 checksum of the ROMMON pkg file. The <filesystem> is usb0 or bootflash:. The <PKG filename> is the downloaded ROMMON pkg file such as C1100-rommon-168-1r-SPA.pkg. 

Router# verify /md5 bootflash:C1100-rommon-168-1r-SPA.pkg
.....................................................................................................Done!
verify /md5 (bootflash:C1100-rommon-168-1r-SPA.pkg) = 5f892952a792a0e6d44d037c0214f493
Step 4

Run the IOS ‘upgrade rom-monitor’ command to begin the ROMMON upgrade process.

Router# upgrade rom-monitor filename bootflash:C1100-rommon-168-1r-SPA.pkg R0
Caution 

Do not remove hardware, turn off power, or interrupt the router in any way during the ROMMON upgrade. Although the router should be able to recover from most interruptions during the ROMMON upgrade, certain scenarios may cause unpredictable problems.

Step 5

When the upgrade command is finished, use the IOS reload command to complete the upgrade process.

…
ROMMON upgrade complete.
To make the new ROMMON permanent, you must restart the RP.
Router# reload
Proceed with reload? [confirm]
 
(The ROMMON boots twice; on the second boot, the upgrade ROMMON starts)
Step 6

If autoboot is not configured, at the ROMMON prompt, boot an IOS_XE image. The IOS-XE image must successfully boot to an IOS prompt to finalize the ROMMON upgrade process. 

Rommon 1 > boot bootflash:c1100-universalk9_ias.16.08.01.SPA.bin
Step 7

If an autoboot option is not configured, boot an IOS_XE image at the prompt. The IOS-XE image must successfully boot to an IOS prompt to complete the ROMMON upgrade process.

Step 8

At the IOS prompt, use the show rom-monitor R0 command to verify the ROMMON version matches the ROMMON PKG file version.
