About This Manual

This document describes the board level operations of the TMS570LS31

Hercules Development Kit (HDK). The HDK is based on the Texas Instruments

TMS570LS3137 Microcontroller. The TMS570LS31 HDK is a table top card that

allows engineers and software developers to evaluate certain characteristics of

the TMS570LS3137 microcontroller to determine if the microcontroller meets the

designer application requirements. Evaluators can create software to execute on

board or expand the system in a variety of ways.

Notational Conventions

This document uses the following conventions.

The TMS570LS31 HDK will sometimes be referred to as the TMS570 HDK or

HDK.

Program listings, program examples, and interactive displays are shown in a

special italic typeface. Here is a sample program listing.

1.5 HDK Specifications

Board supply voltage: 5V–12V Vdc

Board supply current: 130mA typ (fully active, CPU at 180 MHz)

Dimensions: 4.90” x 4.30” x 0.85” (LxWxH)

1.6 Basic Operation

The HDK is designed to work with TI’s Code Composer Studio and other 3rd party

ARM IDEs (Integrated Development Environments). The IDE communicates with

the board through the embedded emulator or an external JTAG emulator. To

start, follow the instructions in the Quick Start Guide to install Hercules specific

software. This process will install all of the necessary development tools,

documentation and drivers.

1.7 Memory Map

The TMS570LS31 family of MCUs have a large byte addressable address space.

The memory map table shows the address space of a TMS570LS3137

microcontroller on the left with specific details of how each region is used on the

right. By default, the internal memory sits at the beginning of the address space.

The SDRAM is mapped into CS0 space on the EMIF. CS2/3/4 are used for

synchronous memory for example SRAM, NOR flash, NAND flash etc.

To use EMIF, the MPU has to be enabled, and the CS regions have to be

configured as “device mode” or “strongly ordered mode” through MPU.

1.8 Power Supply

The HDK board operates from a single +12V external power supply connected to

the main power input (P1), a 2.5 MM, barrel-type plug. Internally, the +12V input

is converted into +1.2V, +3.3V and +5.0V using Texas Instruments swift voltage

regulators and PTH power module. The +1.2V supply is used for the MCU core

TMS570LS31 HDK User Guide

while the +3.3V supply is used for the MCU's I/O buffers and other components

on the board. The +5.0 volt supply is used for ADC power (2nd option) and USB

VBUS.

There are multiple power test points on the HDK board. The three main test point

pairs provide a convenient mechanism to check the HDK’s current for each

supply. The table below shows the voltages for each test point and what the

supply is used for.

In addition to on board XDS100V2 JTAG. One 20pin ARM JTAG header is added

for using an external emulator. This is the standard interface used by JTAG

emulators to interface to ARM microcontrollers. The pinout for the connector is

shown in the figure.

2.2.2 Ethernet Interface

The TMS570LS3137 integrates an MII/RMII ethernet MAC on chip. This interface

is routed to the on board PHY via CBT switches. The board uses a DP83640

PHY. The interface is isolated and brought out to a RJ-45 connector with

integrated magnetics, J1. The pinmux control DIP S2 is used to control the CBT

FET switch for RMII, MII or other functions.
