SDK-Builder

Product Overview

The GainSpan SDK-Builder is a web-based tool for building custom firmware binary images for GainSpan Low Power Embedded GS1011M/GS1500M Wi-Fi Modules. It allows users to rapidly customize wireless and network stack functionality into their embedded applications and integrate with an external host MCU. This enables users to continue to leverage existing host MCU tool chain for developing host application while using the GainSpan SDK-Builder tool to customize wireless and network stack capabilities of their system.

The GainSpan SDK-Builder tool eliminates the need to use pre-built firmware binary images, provided with GainSpan GS1011M/GS1500M EVK Mrk II evaluation kits, and allows users to create custom firmware binary images on-demand tailored to their end application.

Benefits

  • Simplified web-based tool that enables customization of software features tailored to end application
  • Accelerates time to market by reducing development time for custom embedded applications
  • No need to purchase embedded Wi-Fi module software development tool chain
  • Builds application-specific customized embedded firmware binary images for use with flash management tools

Features

  • Access to complete suite of GainSpan Wi-Fi & Networking services software
  • Menu-based build configuration options listed by product and software version
  • Built-in intelligence to eliminate possibility of invalid code combinations
  • Binary file size and external flash size indicators to show total memory usage and error messages to indicate memory overflow
  • Description of software modules and valid feature combinations
  • Email notifications to confirm build request and availability of firmware binary images
  • Build History tab to track history of recent builds. Firmware binaries uploaded directly to the Build History tab
  • About Tool tab for instructions on using the tool

  • The SDK-Builder tool is accessible at the GainSpan Support Portal. Once initial registration on the support portal and approval is complete, users can use their support portal credentials to login and access the SDK-Builder tool. The SDK-Builder tool provides a baseline default configuration which includes essential wireless stack features (WLAN Firmware, radio configuration, power save modes (sleep, deep sleep, standby), unsolicited data transmission, WPA/WPA2-Personal security (client)) and networking services (network stack protocols (UDP/TCP), DHCP/DNS client, Over-the-air firmware upgrade using internal flash).
 
  • The feature selection section of SDK-Builder tool has a tabbed structure and allows user to select and configure features such as host interface options, wireless and networking features such as personal and enterprise wireless security, DHCP/DNS servers, HTTP client/server, SSL client/server and other test modes. It also includes selections for Provisioning and Over-the-air Firmware Upgrade ADK using external flash. In addition, real-time firmware binary image size and flash image size indicators show total memory usage and provides alerts if allowable memory limits are exceeded. The tool also includes a Build History tab that lists the builds submitted to date and serves as a repository for the built firmware images. Users can download the firmware images from the Build History tab. The About Tool tab provides users instructions on using the tool.
