Gecko Platform 3.2.2.0 GA Gecko SDK Suite 3.2 September 8, 2021 The Gecko Platform provides infrastructure support for applications developed with higher-level protocols, and it provides an interface with the underlying hardware. It is composed of the following modules: CMSIS Device is a vendor-independent hardware abstraction layer for the Cortex-M KEY FEATURES processor series. CMSIS Device Peripherals provides a complete peripheral API for all Silicon Labs EFM32, EZR32 and Added support for EFR32xG23 devices EFR32 MCUs and SoCs. Peripherals Drivers is the Gecko Platform driver library for EFM32, EZR32 and EFR32 on-chip pe- EFP Voltage scaling and Direct mode on ripherals. Drivers are typically DMA-based and use all available low-energy features. EFR32xG22 and EFM32xG22. Services includes common services such as NVM3 and Power Manager. EFP Coulomb counter Services Common components are used throughout the SDKs. Several fixes related to Power Manager Middleware includes the Capacitive Sensing Firmware Library and the GLIB graphics Middleware library, along with Micrium OS stacks like CAN/CANopen, File System, Networking and CSLIB can now be used with the Gecko USB Device and Host. SDK components Security includes mbed TLS and other security services. Security Mbed TLS library updated to v2.26.0 Operating System includes Micrium OS Kernel as well as other things related to Oper- Operating System ating Systems such as a CMSIS-RTOS2 layer. Added more NOR Flash options for Micrium OS FS The Gecko Bootloader is a code library configurable through Simplicity Studios IDE to generate bootloaders that can be used with a variety of Silicon Labs protocol stacks. The Examples Gecko Bootloader can be used with EFM32 and EFR32 Series 1 and later devices. Coulomb Counter CLI & I2C Examples are example applications illustrating platform functionality. Boards and External Devices Boards and External Devices cover supported hardware. Added support for several new boards Other Gecko Platform Components regroups changes to documentation, project build- Other Platform Components ing and configuration, as well as any other aspects related to Gecko Platform. Updated IAR compiler to version 8.50.9. Updated GCC compiler to version 10.2. RAIL (Radio Abstraction Interface Layer) provides a customizable radio interface layer that supports proprietary or standards-based wireless protocols. RAIL use by application Amazon FreeRTOS Libraries have been protocols such as Silicon Labs Zigbee or Silicon Labs Connect is managed through the added to the Gecko SDK. stack library. Direct RAIL use is exposed through the Flex SDK.
