Follow the instructions in presented order to ensure correct operation of your software and hardware. 1. Installing a USB-Based Emulator or Installing a PCI-Based Emulator 2. Verifying Driver Installation and Attaching to an Emulation Target 3. Applying Power to the Emulator Installing a USB-Based Emulator 1. Install CCES or VisualDSP++ on your computer. The installation includes a USB driver required for your USB-based emulator. If CCES or VisualDSP++ is installed already, you do not need to install it again. HPUSB, USB, and HPPCI Emulators User’s Guide 1-3 USB- and PCI-based Emulator Installation Tasks Note: If you connect the emulator first (before installing CCES or VisualDSP++) to the PC, the Windows driver wizard will not find the drivers for the emulator. 2. Connect one side of the provided USB cable to the USB assembly of the emulator and the other side to an open USB port of your computer. Verifying Driver Installation and Attaching to an Emulation Target is next. Installing a PCI-Based Emulator driver must be installed before you start the HPPCI-ICE for The the first time. 1. Install the HPPCI-ICE hardware. For instructions on installing a PCI card into your computer, consult documentation provided by the computer manufacturer. 2. Install VisualDSP++. VisualDSP++ includes the HPPCI driver needed for your PCI emulation hardware. Refer to the VisualDSP++ Installation Quick Reference Card for details. Verifying Driver Installation and Attaching to an Emulation Target is next. 1-4 HPUSB, USB, and HPPCI Emulators User’s Guide Getting Started Verifying Driver Installation and Attaching to an Emulation Target Before using your USB- or PCI-based emulator, verify that the driver software is installed properly. 1. Open the Windows Device Manager and verify that the HPUSB-ICE, HPPCI-ICE or USB-ICE appears under ADI Development Tools as shown in Figure 1-1. Figure 1-1. Verifying Driver Installation 2. Connect the 14-pin header side of the pod cable to the target board via the debug interface. The 14-pin connector is keyed at pin 3 on the pod cable to ensure that the cable sits correctly on the 14-pin target emulation header. The target board should also have pin 3 keyed. HPUSB, USB, and HPPCI Emulators User’s Guide 1-5 USB- and PCI-based Emulator Installation Tasks not connect or disconnect a USB emulator JTAG header, Do whether powered up or not, to/from a powered target. Applying Power to the Emulator is next. Applying Power to the Emulator The final step is to power up the emulator. The following procedures apply to HP-USB and USB emulators only. Powering up a USB-based emulator: 1. Apply power to target board. 2. Apply power to the emulator 3. If the emulator is not connected to the PC, connect the devices with the USB cable as described in Verifying Driver Installation and Attaching to an Emulation Target. 4. Invoke CrossCore Embedded Studio or VisualDSP++. Powering down a USB-based emulator: 1. Shut down (exit) CrossCore Embedded Studio or VisualDSP++. 2. Disconnect the USB cable from the emulator and PC. 3. Power down the emulator. 4. Power down the target board. the emulator has an “Enable/Power” LED, the power LED lights Ifgreen when power is applied. The power LED lights amber when connected to a session or when the ICE Test utility is used. If the emulator has an “Enable” LED only, the LED lights amber 1-6 HPUSB, USB, and HPPCI Emulators User’s Guide Getting Started when connected to a session or when the ICE Test utility is used. At all other times, the LED should be off. For custom processor boards still in design, refer to the Engineer-to-Engineer Note, Analog Devices JTAG Emulation Technical Reference (EE-68), available from the Analog Devices Web site. This document is a technical reference for implementing the JTAG interface on your target. Now the emulator hardware is ready to be used in conjunction with CCES or VisualDSP++ to debug a processor target system. See “Configurator Software”. Configurator Software CrossCore Embedded Studio and VisualDSP++ development software require a description of your platform (JTAG chain). The platform definition is necessary for the software to communicate with the hardware through the emulator. The VisualDSP++ and CCES include the target configurator utility to configure and test your emulator hardware. The target configurator provides emulator detection, JTAG I/O voltage selection, and JTAG frequency selection. Use the ICE Test (part of the target configurator) to test the target. If any errors are encountered, the errors are reported immediately and the test ends. Each error message recommends a solution to the problem. Refer to the online help for information about “target configurator”, “JTAG frequency”, and “ICE test”. HPUSB, USB, and HPPCI Emulators User’s Guide 1-7 JTAG Frequency Selection JTAG Frequency Selection USB-ICE emulators, high-performance PCI-ICE, and high-performance USB-ICE emulators support a JTAG clock operation up to 50 MHz. all frequencies listed above are supported for all processor fam Not ilies. The displayed frequencies depend upon the processor family. There is a relationship between the JTAG frequency and core clock frequency of the processor. Typically, the core clock runs at a frequency that is more than 2x the JTAG clock’s frequency. On newer Analog Devices processors, the core clock is a variable that sometimes is set by switches or software. the core/JTAG clock relation is not followed, scan failures can Ifprevent the emulator from connecting to the processor. Use the JTAG Frequency Selection dialog box to test and change the rate at which the JTAG Test Clock signal (TCK) runs. To access the dialog box: • CrossCore Embedded Studio users choose Target > Settings > JTAG Frequency Selection after launching a debug configuration. • VisualDSP++ users choose Settings > JTAG Frequency Selection after creating a debug session. 1-8 HPUSB, USB, and HPPCI Emulators User’s Guide Getting Started Figure 1-2 and Figure 1-3 show the JTAG Frequency Selection dialog box. Figure 1-2. HPUSB-ICE JTAG Frequency Selection Dialog Box Figure 1-3. HPPCI-ICE JTAG Frequency Selection Dialog Box HPUSB, USB, and HPPCI Emulators User’s Guide 1-9 JTAG Frequency Selection The tests listed in the Status box are run when you click Test in the JTAG Frequency Selection dialog box. The blue arrow points to the current frequency. The arrow does not change after you run the tests because Cancel goes back to using the frequency pointed to by the blue arrow. To use a different frequency, select the appropriate frequency from the list and click Test. Click OK to use the frequency that is highlighted and tested already. Table 1-1 describes the JTAG Frequency Selection dialog box. Table 1-1. JTAG Frequency Selection Dialog Box Item Description Select frequency (MHz) Selects the frequency to run TCK. Status Updates status of the tests indicated within the test group. The test status indicator can show a “running” icon, “not running” icon, “pass” icon, or “fail” icon, depending on the test status. Test Tests the selected frequency by running the tests in the Status group. NOTE: If tests fail, you may have to shut down the IDE and restart your session. OK Saves the selected frequency. This should only be highlighted if all the tests have passed. Cancel Continues using the frequency pointed to by the blue arrow. encounter a problem launching the CCES or VisualDSP++ Ifat you a certain frequency, delete your debug configuration/session and create a new debug configuration/session. This sets TCK back to the default value. 1-10 HPUSB, USB, and HPPCI Emulators User’s Guide Getting Started HPPCI JTAG I/O Voltage Detection The mode of operation supported by the PCI emulator is dependent on the connection method used for the 14-pin JTAG header on your target. Table 1-2 shows how the target JTAG header connects for legacy and auto detection modes. Table 1-2. HPPCI JTAG Legacy and Auto Detection Modes GND 1 Key (no pin) BTMS BTCK BTRST BTDI GND 2 4 5 6 7 8 9 10 11 12 13 14 EMU GND GND Key (no pin) TMS Target VDDIO / BTMS TCK BTCK TRST BTRST TDI BTDI TDO GND 1 2 4 5 6 7 8 9 10 11 12 13 14 EMU NC TMS TCK TRST TDI TDO HPPCI JTAG I/O -- Legacy Pinout HPPCI JTAG I/O -- Auto Detection Pinout HPUSB/USB Legacy Mode Legacy mode is used for older targets that do not provide a target VDDIO input for automatic voltage detection by the emulator. In this mode, the voltage at which the JTAG signals run is set manually through the Configurator utility. The configurator utility provides a voltage selection setting when configuring the target. and USB-ICE emulators do not support auto voltage HPUSB-ICE detection mode. HPUSB, USB, and HPPCI Emulators User’s Guide 1-11 HPPCI JTAG I/O Voltage Detection HPPCI-ICE Legacy/Auto Detection Mode The factory default for the pod shown in Figure 1-4 is legacy mode. For more information about available modes, refer to “Auto Detection Mode” on page 1-14. In order to modify the factory default setting, remove the four screws on the bottom of the plastic enclosure. When opening the case, first remove the top of the enclosure with the top facing up. This must be done to ensure that the four light pipes used for the LEDs are not damaged. The default pod setting is shown in Figure 1-5. To determine whether the default setting of your HPPCI-ICE needs to be modified, refer to “Legacy Mode (Factory Default Setting)”. Figure 1-4. HPPCI-ICE Pod 1-12 HPUSB, USB, and HPPCI Emulators User’s Guide Getting Started Figure 1-5. Default Switch Setting for HPPCI-ICE Pod Legacy Mode (Factory Default Setting) Legacy mode is used for older targets that do not support voltages less than 3.3V and do not provide an IOVDD input for automatic voltage detection by the pod. Consequently, the emulator in legacy mode is used for all previously designed 3.3V and 5V target boards. The HPPCI-ICE is 3.3V compliant and 5.0V tolerant in this mode and accepts both 3.3V and 5.0V signals but only drives 3.3V CMOS level signals. In legacy mode, the LED labeled 3.3/5V is lit. The emulator is set to Legacy mode before leaving the factory. The switch must be set in the manner shown in Figure 1-6 to verify that the emulator is in legacy mode, or to change the emulator to legacy mode. HPUSB, USB, and HPPCI Emulators User’s Guide 1-13 HPPCI JTAG I/O Voltage Detection Figure 1-6. Legacy Switch Setting for HPPCI-ICE Pod Auto Detection Mode Auto detection mode is recommended for all newly designed target boards. This mode supports 1.8V, 2.5V, 3.3V, and 5V target boards. PCI-based emulators are 1.8V, 2.5V, and 3.3V-compliant in auto detection mode. This means that the emulator can accept 1.8V, 2.5V, and 3.3V signals and can also drive the respective 1.8V, 2.5V, and 3.3V CMOS level signals. The emulator is also 5V tolerant. Consequently, the emulator accepts 5V signals and drives 3.3V signals to the target. In auto detection mode, the emulator samples the target VDDIO signal (pin 5 on the JTAG header) and drives the JTAG signals from the emulator at the sampled voltage. The respective 1.8V, 2.5V, or 3.3/5V LED also lights up to indicate the voltage at which the JTAG signals are driven. The emulator is set to legacy mode before leaving the factory. The switch must be set in the manner shown in Figure 1-7 to verify that the emulator 1-14 HPUSB, USB, and HPPCI Emulators User’s Guide Getting Started is in auto detection mode, or to change the emulator to auto detection mode. Figure 1-7. Auto Detection Switch Setting for HPPCI-ICE Pod HPUSB, USB, and HPPCI Emulators User’s Guide 1-15 Troubleshooting and Warranty Troubleshooting and Warranty To provide comprehensive troubleshooting advice and warranty information for all emulator and EZ-KIT Lite products, Analog Devices maintains an Engineer-to-Engineer Note. Emulator and EZ-KIT Lite Evaluation System Troubleshooting Guide (EE-175) is available online at: http://www.analog.com.

Please carry out all troubleshooting steps outlined in this document before contacting Analog Devices Processor Tools Support. Also included in the EE-Note, complete warranty and return material authorization (RMA) information for emulators and EZ-KIT Lite products. In general, emulators less than one year old are within warranty, and repairs within that period are free of charge, but there are some limitations to this warranty coverage. For details, see the note. 1-16 HPUSB, USB, and HPPCI Emulators User’s Guide 2 HARDWARE DESCRIPTION This chapter describes the hardware design of the USB- and PCI-based emulators. LEDs This section describes the following LEDs: • “HPUSB-ICE/USB-ICE LEDs” • “HPPCI-ICE LEDs” on page 2-2 • “Pod LEDs” on page 2-2 • “Board LEDs” on page 2-4 HPUSB-ICE/USB-ICE LEDs Four LEDs are located on the enclosure: • 1.8V LED – Signifies that the ICE drives all signals at 1.8V compliant levels. • 2.5V LED – Signifies that the ICE drives all signals at 2.5V compliant levels. HPUSB, USB, and HPPCI Emulators User’s Guide 2-1 LEDs • 3.3/5V LED – Signifies that the ICE drives all signals at 3.3V compliant levels. • ENABLE – This LED is amber when the debugger is enabled. This means that the emulator is driving the JTAG signals, and the connector must not remove or plug onto a target when the light is amber. When the LED is green, the JTAG signals are not being driven, and it is safe to connect to a target. The green LED indicates that the board is powered up but not in emulation mode. HPPCI-ICE LEDs Four LEDs are located on the pod enclosure (Figure 2-1), and five LEDs are located on the daughter board (Figure 2-2). Pod LEDs Figure 2-1. Pod LEDs 2-2 HPUSB, USB, and HPPCI Emulators User’s Guide Hardware Description • 1.8V LED – In auto detection mode, this LED signifies that a target VDDIO of 1.8V has been detected on the JTAG header (pin 5) on the processor target board, and the HPPCI-ICE drives all signals at 1.8V compliant levels. • 2.5V LED – In auto detection mode, this LED signifies that a target VDDIO of 2.5V has been detected on the JTAG header (pin 5) on the processor target board, and the HPPCI-ICE drives all signals at 2.5V compliant levels. • 3.3/5V LED – In auto detection mode, this LED signifies that a target VDDIO of 3.3V or 5V has been detected on the JTAG header (pin 5) on the processor target board, and the HPPCI-ICE drives all signals at 3.3V compliant levels. In legacy mode, this LED is powered automatically, and pin 5 of the JTAG header on the target board is not used to detect the target VDDIO voltage. • ENABLE – This LED is turned on when a CrossCore Embedded Studio (CCES) or VisualDSP++ debug session is running. This LED shuts off every time the session is closed. When this LED is off, it signifies all outputs of the pod logic connected to the target have been three-stated. Three-stating the outputs of the pod when the IDE is inactive prevents the target processor from entering an unknown state during the target power up sequencing. HPUSB, USB, and HPPCI Emulators User’s Guide 2-3 LEDs Board LEDs Figure 2-2. Board LEDs • VCC – This LED signifies that the board is receiving 5V power. If this LED is not active, the HPPCI-ICE does not function properly. • 3V – This LED signifies that the board is receiving 3.3V power. If this LED is not active, the HPPCI-ICE does not function properly. • FPGA[1:0] – These two LEDs are used for factory purposes only. • DONE – This LED is activated when a a CrossCore Embedded Studio or VisualDSP++ debug session is started. The LED should remain active even after the respective session has been terminated. The LED shuts off and re-activates at the beginning of every new session. 2-4 HPUSB, USB, and HPPCI Emulators User’s Guide Hardware Description Custom Processor Boards When designing a custom processor board using Analog Devices processors and DSPs, special care must be taken to ensure that the JTAG interface is designed and laid out correctly. If the board is not designed correctly, communication via the JTAG port may not work. Another side effect may be that the interface works, but you are not able to run at the highest possible JTAG clock frequency. The JTAG clock frequency is dependant on the particular Analog Devices processor, as well as the delay characteristics of the custom processor board. To ensure that the custom board’s JTAG interface is designed and laid out correctly, refer to Engineer-to-Engineer Note, Analog Devices JTAG Emulation Technical Reference (EE-68), available from the Analog Devices Web site. This document is a technical reference for implementing the JTAG interface on your target. HPPCI-ICE The HPPCI-ICE consists of a daughter board and a pod cable. The system is compliant with revision 2.2 of the PCI specification and plugs into 5V-only motherboards. It uses only the 5 volts from the PC’s PCI slot. The pod cable consists of a small PCB that has a multi-conductor cable soldered at each end. The multi-conductor cable is constructed with individual coaxial cables that are encapsulated by shield ground. The PCB in the pod is fully enclosed in a copper-sprayed plastic enclosure. The multi-conductor cables and copper spray reduce system noise and electromagnetic interference.
