4.  Firmware and Tools 

The AirPrime AR7594 are designed 

based on Qualcomm’s MDM9240 chipset, which contains a 

Modem Processor for running modem firmware components and an Application Processor for running 
embedded Linux applications. Various tools are provided by Qualcomm and developed by Sierra 
Wireless for developing and commercializing the AirPrime AR7592. 

4.1. 

Modem Firmware 

The MDM9240 Modem Process contains the following categories of firmware, with possible 
modifications/extensions by Sierra Wireless as indicated: 

 

LTE/ WCDMA/ TD-SCDMA air interface protocols 

 

GNSS engine 

 

IMS protocol stack 

 

AT Command Processor: New AT commands will be added by Sierra Wireless. See 
document [8] for the complete list of AT Commands for the AirPrime AR759x Series. 

 

Data services 

 

Drivers/ BSP: Some modifications will be made to ensure the firmware can communicate with 
the AirPrime AR759x Series hardware properly. 

 

UICC functions 

 

Memory Management: Built-in redundancy and continuous monitoring against memory 
corruption 

 

Antenna Protection 

 

Voice support 

4.2. 

Tools 

The following tools will be needed for the AirPrime AR7594 development, testing and 
commercialization. 

 

Firmware Update Tool 

 

Linux driver and Application Downloader 

 

Provisioning Tool 

 

Logging Tool 

 

Qualcomm’s QXDM (license with Qualcomm required) 

 

Qualcomm’s QPST (license with Qualcomm required)
