We've simplified the firmware software upgrade process. Images now include carrier PRI, module FW, MCU, Yocto, and Legato in a single file. The combined image is the only file needed if you're NOT rebuilding Yocto or the Legato framework.

We also provided the individual component files so you can use the swicwe tool to build custom combined images.

The provided combined images are available in both Windows .EXE and Linux .SPK format, and are applicable to all SKUs. The EXEs are for those upgrading using Windows. The Binaries are for those upgrading using Linux.

Components

A new swicwe tool is also now available to build combined images. This is only needed if you're building a custom Yocto or Legato framework. See AirPrime WP Series Flash Guide and swicwe tool docs for more information.

1. Download the appropriate Windows EXE file.

2. Connect to your target device

3. Run the EXE to upgrade the target.

1. Build a combined image with swicwe tool (optional) See swicwe tool docs for details.

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.

3. Install and download using the swiflash tool. See swiflash docs for details.

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.
