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 337 BGA Microcontroller. The TMS570LS31 HDK is a table top

card that allows engineers and software developers to evaluate certain

characteristics of the TMS570LS31 microcontroller to determine if the

microcontroller meets the designer’s application requirements as well as begin

early application development. 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.

1.6 Basic Operation

The HDK is designed to work with TI’s Code Composer Studio and other ARM

IDE development tools. 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 Code Composer. 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 TMS570LS31

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

HDK 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.

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

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

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

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.
