Overview
Cisco IoT products use the cellular modems from Sierra Wireless. The architecture of the router is such that there is a dependency between the firmware running on the modem and the version of Cisco IOS running on the router. Sierra Wireless builds a Cisco specific firmware package for the modems embedded in routers based on the firmware that has been certified by the carrier. This firmware that the modem runs on, undergoes a thorough testing in the Cisco lab to ensure a seamless integration and functioning between the modem firmware and Cisco IOS. Once evaluated, the firmware is then posted on the website from where the customers can download it.
Firmware Upgrade on the IR807
This section provides information about upgrading Cisco cellular modem firmware on the IR807. To make sure that the modem's firmware and other settings are upgraded correctly, certain packages needs to be downloaded and upgraded on the modem. It is important to identify the modem and SKU type and follow the corresponding sequence.
Unlike other routers, there are three file types that will be upgraded on the WP75xx and WP76xx modems:
- Modem firmware with carrier PRI which is a.spk file
- Modem Legato and Yacto firmware file which is a.spk file
- Modem OEM PRI file which is a.nvu file
Refer to the following table for the SKU, Modem Type, and Firmware.
Firmware Upgrade Procedure
Note
The following examples illustrates how to perform an upgrade. You will need to perform the same steps with each modem file (*.spk and *.nvu) to complete the firmware upgrade.
The following rules apply when upgrading modems:
- Each of the files need to be upgraded separately. You cannot place them together in the same folder and perform a simultaneous upgrade.
- When switching from one carrier to another, only the Firmware file corresponding to the carrier needs to be upgraded. You do not need to re-upgrade with the OEM PRI and Legato-Yocto files. For example: If using an IR807G-LTE-NA-K9 with the ATT SIM in one slot and Sprint SIM in the other slot, simply upgrade with the firmware corresponding to the active SIM.
Perform the following steps to upgrade the modem firmware:
Step 1 Go to the Cisco web page to download the latest certified firmware for your carrier by going to the following location: https://software.cisco.com/download/home/286288566
Step 2 Create a directory in flash to host the firmware, which will be downloaded in step 3.
Create directory filename [flash]? <enter>
Step 3 Download the firmware to the directory in the router flash. This can be done by hosting the firmware on an FTP or TFTP server, and connecting to that server via any WAN interface on the router. Below is a example showing the modem firmware downloaded onto the router flash over the FastEthernet interface:
Note Output edited for brevity.
Address or name of remote host []? 192.168.1.1
Source filename []? /<directory>/WP75xx_07.12.09.00_Legato_Yacto_MCU.spk
Destination filename [WP75xx_07.12.09.00_Legato_Yacto_MCU.spk]?<enter>
/<directory>/ WP75xx_07.12.09.00_Legato_Yacto_MCU.spk

Step 4 Verify that the firmware is available on the newly created directory inside router flash by using the following command:
IR807# dir flash:WP75xx_07.12.09.00_Legato_Yacto_MCU
Directory of flash:/WP75xx_07.12.09.00_Legato_Yacto_MCU/
-rw- 24444106 Sep 4 2017 09:58:34 -08:00 WP75xx_07.12.09.00_Legato_Yacto_MCU.spk
Step 5 Initiate a modem firmware upgrade using the microcode reload command.
Example: Firmware upgrade of WP7504 modem with a.spk file
IR807#microcode reload cellular 0 0 modem-provision flash:WP7504_07.12.09.00_00_SPRINT_001.020_000.spk
