Page 12: Introduction To The Arm710T Header Card
Overview of the ARM710T Header Card Introduction to the ARM710T header card The ARM710T header card (part number KPI-0032A) is a processor daughter board for the ARM development board (HBI-0011B). This guide describes how to set up your ARM development board and ARM710T header card.

Page 15 Chapter 2 Setting up your System This chapter describes how to set up your ARM development board to work with the ARM710T header card and gives details of connecting debuggers. It contains the following sections: • Setting up your ARM development board on page 2-2 •...
Page 16: Setting Up Your Arm Development Board
The ARM710T header card plugs into the top left hand corner of the development board, with the ARM logo on the silk-screen positioned as shown in Figure 2-1, so that the header is flush with the development board. The correct way to mount the header card is shown in Figure 2-1.
Page 17 2.1.1 Setting the bus clock frequency The ARM710T header card requires the bus clock frequency, BCLK, of the board to be set to 4, 8, 16 or 20MHz. This is set by changing the FREQ SELECT switch, S1, on the ARM development board, shown in Figure 2-2.
Page 18: Debugging Using Angel
The binary image for the Angel is supplied with the ARM development board. To download, execute and debug code the host needs to be running the ARM Debugger for Windows or armsd program supplied as part of the ARM Software Development Toolkit, available separately from ARM.
Page 19: Debugging Using Multi-Ice
The Multi-ICE debugging system provides a nonintrusive debugging system with fast download and is available separately from ARM. The ARM710T header card provides Multi-ICE connector, PL5, which connects via a 20-way ribbon cable to the Multi-ICE hardware. The Multi-ICE server and debugger software should be run on the host computer.
Page 20: Debugging Using Embeddedice
Setting up your System Debugging using EmbeddedICE Debugging using EmbeddedICE is not recommended because EmbeddedICE does not support debugging with the caches on. © Copyright ARM Limited 1999. All rights reserved. ARM DUI 0114A...
Page 21 Chapter 3 Configuring the ARM710T Header Card This chapter describes the board link and switch settings that configure the ARM710T header card. It contains the following sections: • Setting the core clock frequency on page 3-2 • Surface mount links on page 3-4 •...
Page 22: Setting The Core Clock Frequency
Configuring the ARM710T Header Card Setting the core clock frequency On the ARM710T header card, a phase-locked loop performs the core clock generation. The frequency and source of the core clock is determined by the settings of links LK4 and LK5. The positions of LK4 and LK5 are shown in Figure 3-1.
Page 23 EXTCLK 0 (stopped) Operation is guaranteed only for those table values which generate frequencies up to 40MHz. Note Do not select any combination other than shown in the table. © Copyright ARM Limited 1999. All rights reserved. ARM DUI 0114A...
Page 24: Surface Mount Links
Configuring the ARM710T Header Card Surface mount links The ARM710T header card has three surface mount links, LK1, LK2, and LK3, which should not be moved for normal operation. Link LK1 sets the global bus enable, GBE, to HIGH (A-C position, default) or LOW (B-C position). Links LK2 and LK3 are used to control which grant and request signals (from the arbiter on the ARM development board) are used by the processor.
Page 25: Using The External Clock Input
A 50-ohm mini-coax connector, SK5, is provided to allow an external clock source to drive core clock, FCLK, of the ARM710T. A 47-ohm resistor, R20, provides an approximate 50-ohm termination. The EXT link of LK5 should be fitted before an external clock source is connected to SK5.
Page 26: Setting The Bus Clocking Mode
Note Synchronous clocking mode is not supported on this header card. For more details of clocking modes see the ARM710T Datasheet. © Copyright ARM Limited 1999. All rights reserved. ARM DUI 0114A...
Page 27: Setting The Endianness
To configure the ARM710T header card for big-endian operation: Fit BIGEND link (LK4) on the ARM development board. Reset the ARM710T. It automatically assumes a little-endian memory system. Change the ARM710T to BIGEND mode by setting bit 7 of coprocessor 15 register 1, see Example 3-1. Note Any byte accesses before this bit is set will be little-endian so will not access the expected data.
Page 29 Chapter 4 Circuit Descriptions This chapter describes the operation of the ARM710T header card. It contains the following sections: • The header card circuit board on page 4-2 • Power measurements on page 4-8. © Copyright ARM Limited 1999. All rights reserved.
Page 30: The Header Card Circuit Board
Multi-ICE, and EmbeddedICE connectors. 4.1.1 Processor in PGA The ARM710T processor is supplied in a 299-pin pin grid array (PGA) package. A number of inputs are tied to default values through resistors. These are listed in Table 4-1.
Page 31 Clock generation A PLL chip (U1) generates the high-speed clock, FCLK, which is used to clock the core of ARM710T. The PLL chip has two programmable outputs, CLK and 2X which is double the frequency of CLK. The links, LK4 and LK5, can be used to set the frequency of the core clock, FCLK, as shown in Table 2-1 on page 2-3.
Page 32 Circuit Descriptions Connectors The ARM710T header card has four 60-way sockets (SK1-4) mounted on the underneath. These correspond to the four 60-way plug connectors (PL1-PL4) on the development card, which allow the header card to be fitted to the development board.
Page 33: Logic Analyzer Connectors
Six 20-way box headers, POD1-6, are provided to allow connection of Hewlett Packard 20-pin (HP 01650-63203) pods suitable for use with an HP1650B-series logic analyzer and thus trace the ARM710T activity. These connectors can also be used for expansion purposes and give access to coprocessor bus, CPD[31:0]. The pinout of connectors POD1 to 6 is given in Figure 4-1.
Page 34 The signal RTCK, returned TCK, is connected to TCK on the header card, to allow Multi-ICE to make use of the adaptive clock timing option. The signal nSRST can be used by the Multi-ICE unit to reset the ARM710T and ARM development board.
