1. Overview
The serial bootloader allows the loading of firmware images to a SAMG55J19 device over a serial
connection. It is intended for use with Microchip PLC stacks such as G3 and PRIME, but it also can be
used with other non-PLC applications.
The embedded serial bootloader preprogrammed in the SAMG55J19 receives an image of the application
in binary format (.bin) over one of the serial interfaces and writes it in the application part of the internal
MCU Flash. The host may be a PC or another MCU/MPU.

The firmware package provided along with the PL360G55Cx-EK includes a pre-compiled image of the
embedded serial bootloader image.
1.1 Supported Platforms and Interfaces
The embedded bootloader is supported on PL360G55CF_EK and PL360G55CB_EK boards.
The embedded bootloader can work with two serial interfaces of the evaluation kit indistinctly: USB and
mikroBUS
™
UART.
