Flash Progamming via CAN BSL (Bootstrap Loader)

Introduction and Requirements

Application Note 5 V1.0, 2009-10

1 Introduction and Requirements

The Infineon XC2000/XE166 Family of devices (Table 1) include a built-in CAN Bootstrap Loader (CAN BSL).

Using the CAN BSL, it is possible to load code or data into the internal PSRAM of the device via the MultiCAN

interface. What is not available however, is a built-in mechanism for internal flash programming.

This application note will demonstrate how to program the internal flash of XC2000/XE166 devices via the CAN

BSL.

The example described makes use of the Tasking compiler tool. However to debug and download readable Hex

files, it is possible to directly use the Hitex tool (HiTOP53) included in the Infineon UConnect-CAN XE164 kit.

1.1 Hardware Requirements

The following hardware is required for the example described in this application note:

• Two XC2000/XE16x boards

– If a compiler and debug tool are already installed, the application software can run in any two Infineon Easy

Kit boards equipped with a target device listed in Table 1. The Infineon UConnect-CAN XE164 comes with

a free compiler and debug tool development suite (a size limited evaluation version). In the example

described in this document, the UConnect-CAN XE164 is the ’host’ board, while the XE167FM EasyKit with

active CAN BSL, acts as the ’slave’ board.

• Terminal program; MTTTY for example.

– This is used to give commands to the host and to display actual states and error messages.

• CAN bus cable

• CAN Analyzer tool (optional)
