AN1326: Transitioning to the Updated Gecko Bootloader in GSDK 4.0 and Higher
● Gecko Bootloader project structure changes
● Gecko Bootloader configuration changes
● Gecko Bootloader component configurator
● Configuring storage slots in the Gecko Bootloader v2.x
● Adding postbuild steps for Gecko Boot-loader v2.x
● New linker file generation system
■Gecko Bootloader v2.x, introduced in GSDK 4.0, contains a number of changes compared to Gecko Bootloader v1.x. Many of these changes are due to an underlying framework redesign that results in an improved developer experience in Simplicity Studio 5 as well as enhanced compatibility within the GSDK. This document describes the differences between the versions, including how to configure the new Gecko Bootloader within Simplicity Studio 5.
■Gecko Software Development Kit suite (GSDK) version 3 (GSDK v3.0) introduced a new underlying Gecko Platform architecture based on components. Beginning with GSDK 4.0, t he Gecko Bootloader now uses this underlying architecture. With Simplicity Studio 5 (SSv5) and GSDK 4.0, developers working with Gecko Bootloader will benefit from the following component-based project configuration features:
●Search and filter to find and discover software components that work with the target device
●Automatically pull in all component dependencies and initialization code
●Configurable software components including peripheral inits, drivers, middleware, and stacks
●All configuration settings are in C header files for usage outside of Simplicity Studio
●Configuration validation to alert developers to errors or issues
●Easily manage all project source via git or other SCM tools
●Managed migration to future component and SDK versions
●Simplified transitions from Silicon Labs development kits to custom hardware
■Other features of the SSv5/GSDK 4.x development environment include:
●Project source management options (link to SDK sources or copy all contents to user folder)
●Graphical pin configuration through the Pin Tool
●Redesigned Radio Configurator with a fresh UI that's more intuitive for single- and multi-PHY customization
●Iterative development (configure components, edit sources, compile, debug) using SSv5 configuration tools and third-party IDEs
●GNU makefiles as a build option
■This document summarizes the differences between the Gecko Bootloader v2.x in GSDK 4.0 and earlier AppBuilder-based versions. These differences include:
●Differences between AppBuilder and the new component-based Project Configurator
●Comparison of the new Project Configurator components with AppBuilder plugins
●Features of the Pin Tool, now used instead of Hardware Configurator
●Other differences including:
▲Linker file
▲Additional Macros
▲Postbuild steps
▲Main bootloader in main flash
▲Callbacks
▲Storage Slots
▲App Properties
