CANopen Mini Bootloader PAULUS

ANSI-C source code of an CANopen boot loader useful for easy In-System-Programming and firmware updates (not only for CANopen devices)

 

Overview

Modern device designs need enormous flexibility in hard- and software. Today hardware is equipped with plenty of resources in order to allow software changes later on. Software itself has to provide means to enable an update/upgrade of the current firmware. At this point in-system-programming offers the greatest possibilities, and thus a change of the software too.

Bootloader with a communication interface allow to do firmware updates by using an appropriate network.
Standardized communication objects and algorithms garuantee a high level of transparency and user friendliness.

Description

Software Update

PAULUS bootloader offers this flexibility for devices in CAN/CANopen networks, because CANopen provides with the SDO Transfer standardized mechanisms
for the transmission of big data volume.

The bootloader itself works independently from the application as a minimal CANopen slave node according to CiA-301.
A software update can be executed with a CANopen master or configuration tool in the user flash code memory.
PAULUS is optimized to code size and widely compatible to CANopen.

Requirements

Some CANopen services are always available, othercan be activated by a configuration file.

• NMT Error - heartbeat creation by bootloader is available
• emergency services can be used with limitations
• CANopen Layer Setting Services are supported
• CANopen bootloader is SDO server
• PDO service is not supported

To divide protocol layer and harware application layer principally allows the usage on all targets.

Features

With PAULUS a new generation of CANopen bootloaders is available. Aim of the development was the creation of a compact, modular and memory saving bootloader platform for different hardware architectures.
• memory saving - up to 50% less memory space is needed in contrast
to the old bootloader generation
• modular - applicable to further hardware architectures in short
time
• compact - clear and easily understandable code allows fast customer specific adaptions

Typical values for needed memory are:
• 4 up to 8 KB flash
• 2 KB RAM
