CAN Bus Bootloader for Hercules™ Microcontrollers

A bootloader enables field updates of application firmware. A controller area network (CAN) bootloader enables firmware updates over the CAN bus. The CAN bootloader described in this application report is based on the Hercules™ARM®Cortex®-R4/R5 microcontrollers (TMS570LSx, TMS570LCx, RM4x, and RM5x). This application report describes the CAN protocol used in the bootloader and details each supported command.
