Preface SPNU567 – September 2012 Read This First About This Manual This document describes the board level operations of the RM42 Hercules™ Development Kit (HDK). The HDK is based on the Texas Instruments RM42L432 Microcontroller. The RM42 HDK is a table top card that allows engineers and software developers to evaluate certain characteristics of the RM42L432 microcontroller to determine if the microcontroller meets the designer application requirements.
Chapter 1 SPNU567 – September 2012 Introduction The RM42L432 HDK is a low cost and easy to use hardware and software platform for evaluating the functionality of the Texas Instruments RM42L432 microcontroller family. Project collateral, schematics and PCB layouts discussed in this application report can be downloaded from the following URL: (http://processors.wiki.ti.com/index.php/RM42_HDK_Kit). 1.

HDK Specifications www.ti.com 1.5 HDK Specifications • • • 1.6 Board supply voltage: 5 V to 12 V DC Board supply current: 130 mA typ (fully active, CPU at 100 MHz) Dimensions: 4.90” x 4.30” x 0.85” (LxWxH) Basic Operation The HDK is designed to work with TI’s Code Composer Studio and other third party ARM IDEs. The IDEs communicate with the board through the embedded emulator or an external JTAG emulator.
Chapter 2 SPNU567 – September 2012 Physical Description This chapter describes the physical layout of the RM42 HDK board and its interfaces. 2.1 Board Layout The RM42 HDK board a 4.9 x 4.3 inch (125 x 109 mm.) six layer printed circuit board that is powered by either +5 V USB power from an external +5 V to +12 V only power supply or by USB VBUS. Figure 2-1 shows the layout of the RM42 HDK board. RM42L432 Figure 2-1.
Connectors www.ti.com 2.2 Connectors The HDK board has ten interfaces to various peripherals. These interfaces are described in Table 2-1. J4 P1 J15 J5 J3 J10 J9 RM42L432 J11 J1 J2 Figure 2-2.

J1, J2 Screw Terminal Block for CAN Bus 2.2.4 J4, XDS100V2 USB JTAG Interface The USB connector J4 is used to connect to the host development system which is running the software development IDE (CCS for example). Before the board is shipped, the XDS100V2 port1 is configured as JTAG, and port2 is configured as SCI. The CPLD is also programmed to route the JTAG signals to the MCU.
Connectors www.ti.com +12 V GND P1 text text PC Board Figure 2-5. +12 V Input Jack 2.2.6 Virtual COM Port Interface The internal SCI on the RM42L432 device is connected to the second port of the XDS100V2. The XDS100V2 USB driver makes the second channel of FT2232H appear as a virtual COM port (VCP). This allows the user to communicate with the USB interface via a standard PC serial emulation port. 2.2.
Connectors www.ti.com There are three daughter card interfaces, J9, J10, and J11. These connectors are described in Table 2-4. J9 J10 J11 Figure 2-6. J9, J10 and J11 Connectors Table 2-4.

LEDs 2.3 www.ti.com LEDs The RM42 HDK board has fourteen (14) LEDs. Four of them are under user control. Those LEDs are controlled and programmed by GIO signals. LED DS2, DS3, DS4, and DS5 indicate the presence of the power (+1.2 V, +5 V, 3.3 V, and 12 V) on the board. The LED functions are summarized in Table 2-7 and Table 2-8. Table 2-7.
Jumpers www.ti.com 2.5 Jumpers HDK board has one jumper to select crystal or oscillator for MCU. Table 2-10. Jumpers 2.6 Switch Position 1 - 2 Position 2 - 3 JP1 Oscillator Y3 Crystal Y2 S3, Power-On Reset Switch RM42 MCU has two resets: Warm Reset (nRST) and Power-On Reset (nPORRST). Switch S3 is a momentary switch that asserts power on reset to the RM42L432 device. The nPORRST condition is intended to reset all logic on the device including the test and emulation circuitry. 2.
