The Miriac™-EK5744 is an MPC5744P-based functional safety kit from NXP, built in partnership with Microsys. The kit features a safety-oriented design approach that includes features like hardware redundancy and fail-safe mechanisms. You can use this hardware design for your own safety system. Let's take your Miriac-EK5744 for a test drive! You have the choice of watching a short setup video or following the detailed actions listed below.
The Miriac-EK5744's processor and SBC are powered through the ports shown in the figure below. Use a flathead screwdriver to fasten two leads to the terminal. Ground goes on the left and a 12-24V input supply goes to the right. 20V is the optimal supply voltage to see full functionality. You can use a power adapter or a DC power supply.
Plug in a USB adapter to the UART terminal and the USB to a computer. This connection allows the Miriac-EK5744 to display console messages to your computer.
The Miriac-EK5744 requires a DHCP (Dynamic Host Configuration Protocol) connection. Plug in a network-enabled ethernet adapter to the ethernet port. The out-of-box firmware will proceed if it detects an IP address.
Connect the two CAN ports together, CAN_L to CAN_L and CAN_H to CAN_H as in the image below. Also make sure the CANs switches next to the CAN terminals are in the ON position.
Load the device manager and find the COM port that the Miriac-EK5744 occupies on your computer. The COM port number will vary with each PC.
Connect the COM port to a UART terminal such as Putty or Tera Term. Use the baud rate 115200. Refer to the pop-ups on this page for installation instructions.
Watch the Miriac-EK5744 print status messages. The out-of-box firmware, among other tests, checks for an IP connection, tests the CAN ports, and reports SBC temperature. The firmware tests repeat indefinitely.
Learn how to install and run the Miriac-EK5744 with sample code.

NXP offers a complimentary toolchain called S32 Design Studio (S32DS). The S32 Design Studio is an Eclipse-based IDE that offers comprehensive software writing and debugging capabilities. It supports multiple debuggers including GDB and Lauterbach.
Learn how to create a new project in S32 Design Studio IDE for Power Architecture and the basics to create your own code by running an easy example code.
Short the debug jumper shown in the figure below. This makes the Miriac™-EK5744 ignore watchdog requests.
The Miriac-EK5744 supports debug through JTAG. Plug in a JTAG connector to the JTAG port in the orientation shown in the figure. NXP recommends the P&E Micro USB Multilink or Lauterbach.
