Overview
An increasing number of CANopen FD devices need bootloaders to update firmware in the CANopen FD network. The use of a complete FD CANopen stack for the bootloader is mostly unsuitable because of the large flash memory footprint.
To avoid this waste of flash memory, emotas developed a new CANopen FD Bootloader that needs only few FLASH resources. The bootloader supports the necessary services (USDO, NMT slave, heartbeat producer) and objects. 32 KiB of flash memory are sufficient for the emotas bootloader – and it is still CANopen FD compatible.
The CANopen FD Bootloader is available for different 32-bit micro controllers and can easily be adapted to other targets. It is delivered as ANSI-C source code and thus can be extended by customers e.g. with a password protection mechanism, firmware encryption or a manufacturer-specific back door.
