AWR2544LOP Evaluation Module 1

1 Getting Started

1.1 Introduction

The AWR2544LOPEVM is an easy-to-use evaluation board for the AWR254x mmWave sensing device, with

direct connectivity to the DCA1000 EVM.This EVM kit contains everything needed to start developing software

for the on-chip ARM® Cortex®-R5F controller, and hardware accelerator (HWA 1.5). Also included is on-board

emulation for programming and debugging as well as on-board buttons and LEDs for quick integration of a

simple user interface.

1.2 Key Features

• Speed Wireless Technology 3D waveguide antenna

• XDS110 based JTAG emulation with Serial port for onboard 64-bit QSPI flash programming

• UART to USB Debug port for terminal access using FT4232H

• 60-pin, high-density (HD) connector for external JTAG/ Emulator Interface with TRACE and CSI2 support

• 60-pin, high-density (HD) connector for debug, SPI, I2C and LVDS

• RJ45 connector to stream the captured data over the network to the host PC

• MATEnet Ethernet interface to stream the captured data over the network to an automotive host

• One button and LED for basic user interface

• 12 V power jack to power the board

1.3 What’s Included

1.3.1 Kit Contents

• AWR2544LOPEVM

• 3D waveguide Antenna

• Micro USB cable

• Ethernet Cable

• Mounting brackets, screws, spacers and nuts, to allow placing the PCB vertical

Note

A 12V, > 2.5-A supply brick with a 2.1-mm barrel jack (center positive) is not included. TI recommends

using an external power supply that complies with applicable regional safety standards, such as UL,

CSA, VDE, CCC, PSE, and more. The length of the power cable should be < 3 m.

The following power supply has been tested to work with the AWR2544LOPEVM: SDI65-12-U-P5.

1.3.2 mmWave Out-of-Box (OOB) Demo

TI provides sample demo codes to easily get started with the AWR2544LOP evaluation module (EVM) and to

experience the functionality of the AWR2544LOP radar sensor. For details on getting started with these demos,

see www.ti.com/tool/mmwave-sdk.

2.2 PCB Handling Recommendations

This EVM contains components that can potentially be damaged by electrostatic discharge. Always transport

and store the EVM in the supplied ESD bag when not in use. Handle using an antistatic wristband. Operate on

an antistatic work surface. For more information on proper handling, refer to SSYA010A.

2.3 Power Connections

The AWR2544LOPEVM is powered by the 12-V power jack (>2.5-A current capability). When power is provided

the AR_NRST, VBAT_INT, and 5V0 LEDs glow, indicating that the board is powered up.

Figure 2-4. 12-V Power Connector

Note

After the 12-V power supply is provided to the EVM, TI recommends to press the NRST switch (SW1)

one time to provide for a reliable boot-up state.

2.4 Connectors

2.4.1 MIPI 60-Pin Connector (J19)

This connector provides the standard MIPI 60-pin interface, as shown in Figure 5, for JTAG and trace capability

through emulators such as the XDS560pro. Further information on the emulation and trace header can be found

in the Emulation and Trace Headers Technical Reference Manual.

To use this interface, the JTAG lines from the AWR2544LOPEVM needs to be muxed to MIPI 60-pin connector.

Refer to Section 2.8.1 for more details.

2.4.1.1 MIPI TRACE ECO List

By default, the TRACE signals are not brought out to the MIPI Connector. To enable the TRACE interface on the

MIPI Connector, the following changes should be made.

1. Remove R165 and populate R216

2. Remove R218 and populate R220

3. Populate R227

4. Populate R231

5. Remove R233 and populate R235

6. Populate R217

7. Remove R21 and populate R221

8. Remove R25 and populate R228

9. Populate R232

10. Populate R236

2.4.2 Debug Connector-60 pin (J7)

This connector enables interfacing of LVDS signals to the DCA1000 EVM for data capturing purposes.

Also, the connector has SPI, I2C, JTAG, GPADC, WRMRST, NRROUT, EPWM, and other control signals from

AWR2544LOPEVM for debug purpose.

The SPI is multiplexed to the Debug Connector. For more details refer to Section 2.8.1.

The debug connector supports direct connection to the TMDS273GPEVM for CSI2 data processing. For more

details refer to CSI2 FE Connector ECO List.
