DAP over CAN
DAP over CAN Physical Layer Converter - Enables debugging via the regular CAN pins of the
ECU connector without opening its housing. This connection is electrically robust due to the
nature of the CAN bus. The DXCPL Converter translates Infineon AURIX™ SPD (Single Pin DAP)
encoded DAP messages to the CAN bus physical layer. iSYSTEM hardware solution supports
DXCPL on Infineon AURIX™ TC2xx and TC3xx devices.
For details about DXCPL operation, refer to Infineon Application Note AP32264.
DAP over CAN Physical Layer Converter can be used with:
· iC5700 BlueBox via DTM or
· iC5700 BlueBox via Infineon DAP/DAPE Active Probe or
· iC5700 BlueBox via Infineon AGBT Active Probe and a 10-pin 1.27 mm DAP Converter
Schematic designer must assure the correct state of TRST signal on cold PORST.
iC5700 BlueBox - Hardware platform designed for debugging and testing a wide range of
embedded microcontroller platforms that are based on a variety of processor architectures.
Infineon DAP/DAPE Active Probe - Enables debugging, tracing and testing of Infineon’s
AURIX™ microcontroller family. It supports the DAP and DAPE debug interface operating at
their maximum frequency. Its small and compact hardware size allows for connecting to a
target microcontroller in a confined space as far as 5m away.
Infineon AGBT Active Probe - Enables debugging, tracing and testing of Infineon’s AURIX™
microcontroller family. It supports the DAP and Aurora GigaBit Trace (AGBT) interface
operating at their maximum frequency. Its small and compact hardware size allows for
connecting to a target microcontroller in a confined space as far as 5m away. The Active
Probe supports up to 4 parallel AGBT lanes, running at a maximum bitrate of 5Gbps.
winIDEA IDE - Integrated Software Development Environment delivers the visual insights
required to debug the embedded application, performs timing analysis, measures code
coverage, visualizes RTOS task states and much more. More information
isystem.com/winideaide.
testIDEA - The testIDEA environment simplifies the development of unit tests for embedded
applications. More information isystem.com/testidea.
isystem.connect - Application programming interface (API) with Software Development Kit
(SDK) and supporting a variety of programming languages makes almost the entire range of
features provided by our software, such as winIDEA, its Analyzer and testIDEA, and the
capabilities of our hardware development tools, such as our BlueBox technology and their IOM
accessories. More information isystem.com/sdk.

C– The LED indicator provides the status of the hardware as follows:

· Green – Powered on
· Red – Power supply issue (e.g., burnt fuse)
D– Power supply connection for the Converter. Use provided USB-C cable to power the
converter e.g. from a PC.
CAN 120 Ohm terminating resistor is not implemented on the DAP over CAN Physical
Layer Converter.
iSYSTEM provides cable solutions on request with build in terminating resistor, which
can be easily switched on or off.

winIDEA Configuration
After connecting the hardware follow the steps below to configure the DAP over CAN Physical
Layer Converter in winIDEA:
1. Open Hardware menu / CPU Options.
2. Navigate to the SoC page.
3. Select DXCPL from the Debug channel Mode drop-down.
4. Confirm and establish the debug connection.
Refer to isystem.com/connect for more information on how to connect and configure the
hardware.
