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.

The interface is isolated and brought out to an RJ-45 connector with integrated
magnetics, J1. The pinmux control DIP S2 is used to control the CBT FET switch
for Ethernet or other functions.
The J1 connector is used to provide a 10/100 Mbps Ethernet interface. This is a
standard RJ-45 connector. The cable end pinout for the J1 connector is shown in
the table below.

Before the board is shipped, the FTDI port1 is configured as JTAG, and port2 is
configured as SCI. The CPLD is also programmed to route FTDI JTAG to MCU
JTAG.
The HDK features circuitry to detect the external JTAG emulator. If a device is
plugged onto the header J4 and J19, the DS1 LED will be turned on, and
XDS100V2 JTAG is disabled.
2.2.6 P1,+12VInput
Connector P1 is the input power connector. This connector brings in +12 volts to
the HDK Board. This is a 2.5 mm. jack. The figure below shows this connector as
viewed from the card edge.

2.2.7 SCIInterface
The internal SCI on the TMS570LS31 device is routed to the 2nd port of FTDI
chip. The FTDI USB driver makes the FT2232H 2nd channel appear as a virtual
COM port (VCP). This allows the user to also have standard PC serial
communications with the HDK using the same USB interface as the on-board
emulator
2.2.8 DaughterCardInterface
The HDK provides expansion connectors that can be used to accept plug-in
daughter cards. The daughter card allows users to build on their EVM platform to
extend its capabilities and provide customer and application specific I/O. The
expansion connectors are for all major interfaces including asynchronous
memory, peripherals, Flexray, and A/D expansion.
The pin outs for this interface are documented in Chapter 3. There are three
daughter card interfaces, J9, J10, J11. These connectors are described in the
table below.

2.3 LEDs
The TMS570LS31 HDK board has nineteen (19) LEDs. Eight of these LEDs
(Table 13 are under user control: seventeen are white LEDs and two are tri-color
LEDs. Those LEDs are controlled and programmed by NHET signals.
LEDs DS2, DS3, DS4, and DS5 indicate the presence of the power (+1.2V, +5V,
3.3V, and 12V) s on the board. The LED functions are summarized in the table
below.

2.4 S2 DIP Switch
There is one 4-position DIP switches located on the left-bottom corner at
reference designator S2. By default, all of the switches are set to the “OFF”
position and should remain in that position when completing the steps in this user
guide.
Figure 6, DIP Switch Settings
The S2 DIP switch is reserved for user applications. Table 15 describes the
function of each channel on S2.

*Note: S2:1 indicates slide 1 on the S2 DIP switch, S2:2 indicates slide 2 on the
S2 DIP switch, and so on.
2.5 Jumpers
HDK board has two (2) jumpers which are used to enable/disable the on-board
SDRAM and select 5V or 3.3V ADC as such:
