The Gecko Bootloader#

Silicon Labs Connect only supports the Gecko Bootloader which is available for the Wireless Gecko (EFR32™) portfolio. For the standalone bootloader, the UART XMODEM Bootloader example is recommended. For the application bootloader, either the SPI Flash Storage Bootloader (if SPI flash is attached the EFR32) or the Internal Storage Bootloader applications are recommended. Note that the OTA protocol available for Silicon Labs Connect only supports single image bootloaders.

Once you have compiled the bootloader, make sure to flash it (the <projectname\>-combined.s37 file) on your device before flashing the main firmware.
