Important: Customer and Carrier configurations must both be upgraded.

You need to choose and download your customer configuration package, and then the carrier configuration, before completing the upgrade process.

The EXEs are for those upgrading using Windows. The Binaries are for those upgrading using Linux.

Configuration Downloads

Download your customer configuration file and the all SKUs carrier configuration file:

Customer

Carrier

The AT commands AT!ENTERCND="A710" followed by AT!SKU? will provide your SKU number. If your SKU is not listed, or you're unsure how run AT commands, please contact your FAE.

Release Notes

For Firmware release notes, see the WP8548_WP750x_Release11_CRN.pdf
For Legato upgrade info, see Upgrade Notes
For MangOH information, see mangOH

The firmware requires both customer and carrier configurations to be upgraded. Download the Windows EXE files.

Follow these steps:

Connect to your target device
Upgrade the customer configuration
Upgrade the carrier configuration

1. Connect Device

Connect your target device to your host PC through a USB in Windows.

Go to Device Manager and check that the target has enumerated as a "DM" serial port. See Not Enumerating as DM Port? if your target isn't displayed in the list.

2. Upgrade Customer Configuration

Double-click the .exe file to run the upgrade.

The target will boot in Airplane mode after the upgrade if this is the first use of this configuration.

3. Upgrade Carrier Configuration

Double-click the .exe file to run the carrier upgrade.

The target will boot in Online mode after the upgrade.

The firmware requires both customer and carrier configurations to be upgraded. Download the Binaries files.

Follow these steps:

Install swiflash tool
Connect to your target device
Upgrade the customer configuration
Upgrade the carrier configuration

1. Install swiflash tool

Follow these instructions for Ubuntu/Debian distributions:

wget http://updatesite.sierrawireless.com/legato-spm/debian/legato-spm.list -O - | sudo tee /etc/apt/sources.list.d/legato-spm.list
wget http://updatesite.sierrawireless.com/legato-spm/debian/legato-spm.key -O - | sudo apt-key add -
sudo apt-get update
sudo apt-get install swiflash

For alternate distributions, please consult swiflash docs.

2. Connect Device

Connect your target device to your host PC through USB.

Check that a /dev/ttyUSBX serial port is mounted on your system; this will be the DM port that's necessary to handle the download. If this serial DM port isn't mounted, enablement must be forced for the DM port and the module needs to be switched to bootloader mode. See swiflash docs for details.

3. Upgrade Customer Configuration

Run this command to update customer configuration:

swiflash -m <module> -i <Customer_Configuration_Binary>
where <module> is either WP85XX or WP75XX depending on your module type, and <Customer_Configuration_Binary> is the above downloaded binary

4. Upgrade Carrier Configuration

Run this command to update carrier configuration:

swiflash -m <module> -i <Carrier_Configuration_Binary>
where <module> is either WP85XX or WP75XX depending on your module type, and <Carrier_Configuration_Binary> is the above downloaded binary

Not Enumerating as DM Port?

If the target is enumerating as an ECM device only (i.e., Ethernet over USB), use the command configEcm off in a Linux shell to allow DM to enumerate in the USB port.

Not Enumerating as DM Port?

If the target is enumerating as an ECM device only (i.e., Ethernet over USB), use the command configEcm off in a Linux shell to allow DM to enumerate in the USB port.

If ECM-only enumeration is preferred, access the A5 console via UART, Ethernet, or USB (ADB), and run command configEcm on. Alternatively use configEcm to list optional parameters for the ECM configuration.

After upgrading to this release, using configEcm should no longer be required for future upgrades.
