2 Introduction

Thank you for choosing the MicroSys SBC-5744 Single Board Computer system. This manual details all its features and will help you obtain the best performance from the SBC.

2.1 Safety and Handling Precautions

ALWAYS use the correct type and polarity of the power supply!

DO NOT exceed the rated maximum values for the power supply! This may result in severe permanent damage to the unit, as well as possible serious injury.

ALWAYS keep the unit dry, clean and free of foreign objects. Otherwise, irreparable damage may occur.

Parts of the unit may become hot during operation. Take care not to touch any parts of the circuitry during operation to avoid burns, and operate the unit in a wellventilated location. Provide an appropriate cooling solution as required.

ALWAYS take care of ESD-safe handling! Many pins on external connectors are directly connected

to the CPU or other ESD sensitive devices. Make or break ANY connections ONLY while the unit is

switched OFF. Otherwise, permanent damage to the unit may occur,

which is not covered by warranty.

There is no separate SHIELD connection. All the metal sheaths of shielded connectors are

connected to GND. Also, all mounting holes of the carrier board are

connected to GND. The module’s mounting holes are not connected to GND Take this into account when handling and mounting the

unit.

2.2 Short Description

The miriacTM EK-5744 is a functional safety evaluation kit, based on the NXP MPC5744P MCU.

It provides a solid base for custom developments and shows how to use the MPC5744P for devices meeting any of the standards IEC 61508/62061 (up to SIL3), ISO 13849 categories 1 and 2 and performance levels a-d or similar.

Typical applications for devices based on the MPC5744 will run in the fields of manufacturing systems engineering, plant engineering, transportation, automotive and avionics where safety standards as shown above have to be implemented.

The MPC5744P microcontroller consists of two e200z4 Power Architecture cores running in delayed lockstep mode. Each of these two cores monitors and supervises the other. Additionally, the MCU implements system-wide error detection strategies.

The EK-5744 provides analog and digital inputs and outputs which have been implemented following the safety requirements of IEC 61508 and ISO 13849. Singlechannel architecture is provided for lower safety requirements, dual-channel architecture will allow you to even fulfill higher safety requirements.

For safety related communication (e.g. via CANopen safety) you may use a redundant CAN interface. This interface may also be used for non-safety-related communication.

For integration into a network the board provides a 10/100MBps Ethernet interface (RJ45). Utilizing an appropriate protocol stack, this interface may also be used for safety-related communication (e.g. using openSAFETY or SoE). In addition to that, the evaluation kit EK-5744 allows full access to all MCU signals. This gives you the opportunity to enhance the EK-5744 with your own functionality.

The EK-5744 is shipped with a firmware. This firmware contains safety functions and an API (“application programming interface”) used to access the MCU and EK-5744 features. Using this firmware and API makes it easier for you to build your own devices conforming to the safety standards IEC 61508/62061 and ISO 13849.

3 Quick Start Guide

3.1 Prerequisites

Always make sure to handle the EK-5744 unit ESD-safe! Otherwise, the unit may suffer permanent damage.

Also, do not lay the unit directly on a metal surface, as this may result in short circuits and damage to the board.

On receipt of the unit, unpack it and make sure that is clean and free of visible damage or foreign objects.

3.1.1 Minimum Requirements

To operate the system, you will need at least the following items:

■ an adequate power supply, delivering 24V DC (stabilized) / 2 A min.

■ an RS232 serial cable with an RJ12 connector

■ a serial terminal, such as a PC with a port running a terminal software (e.g.

TeraTerm, HyperTerminal, putty, Kermit...), or else a hardware serial console.

Choose the following parameters:

(a) 115200 Bd (b) 8 Data bits (c) No parity (d) 1 Stop bit

3.1.2 Recommended Items

The following items are not absolutely necessary, but strongly recommended for practical operation and development purposes:

■ Network connection via LAN port (RJ45) to your local network

■ TFTP server available for downloading within the network

(Hint: may run on the same PC as the serial Terminal)

3.2 Board Preparation and Power-Up

■ Make sure the switch BOOT, located on the EK-5744 carrier board, is set

properly in order to select the correct boot source and board configuration. For more details see chapter 5.3 and 5.4.

After Power-On, the green LED on the carrier should light up.

IF NOT, DISCONNECT THE UNIT IMMEDIATELY FROM THE POWER SOURCE AND CHECK FOR FAULTS!
