European CE Requirements Nohau has included the following information in order to comply with European CE requirements. User Responsibility The in-circuit debugger application, as well as all other unprotected circuits need special mitigation to ensure Electromagnetic Compatibility (EMC). The user has the responsibility to take required measures in the environment to prevent other activities from disturbances from the debugger application according to the user and installation manual. If the debugger is used in a harsh environment (field service applications for example), it is the user s responsibility to control that other activities cannot be disturbed in such a way that there might be risk for personal hazard/injuries. Special Measures for Electromagnetic Emission Requirements To reduce the disturbances to meet conducted emission requirements it is necessary to place a ground plane on the table under the pod cable and the connected processor board. The ground plane shall have a low impedance ground connection to the host computer frame. The insulation sheet between the ground plane and circuit boards shall not exceed 1mm of thickness. System Requirements CAUTION Like all Windows applications, the Seehau software requires a minimum amount of free operating system resources. The recommended amount is at least 40%. (This is only a guideline. This percentage might vary depending on your PC.) If your resources are dangerously low, Seehau might become slow, unresponsive or even unstable. If you encounter any of these conditions, check your free resources. If they are below 40%, reboot and limit the number of concurrently running applications. If you are unable to free at least 40% of your operating system resources, contact your system administrator or Nohau Technical Support at support@nohau.com. The following are minimum system requirements: Pentium 200 (Pentium II or faster is recommended) Single-Processor System Windows 95, 98, NT, 2000, or 2000 ME Random Access Memory (RAM) For Windows 95/98: 64 MB For Windows NT/2000/2000ME: 128 MB iv Preliminary EMUL IP2K PC User Guide

EMUL IP2K PC User Guide Warnings To avoid damage to the pod or to your target, do not connect the pod to your target when the target power is on. Do not apply power to your system unless you are sure the target adapter is correctly oriented. Failing to do so can cause damage to your target. When using the pod with a target, disable all pod resources that are duplicated on the target. Failure to disable the pod s resources can damage the pod or the target or both. When installing a controller into a pod, never press on the chip body. Press only on the carrier or cover. Pressing on the chip might bend pins and cause short circuits.

EMUL IP2K PC User Guide Overview of the EMUL IP2K PC Emulator System Hardware The basic hardware for the EMUL IP2K debugger system is the EMUL IP2K PC/USB JTAG. At present, Seehau IP2K supports the IP2022 chip. Refer to Chapter 2, Installing the Hardware for detailed hardware information. Software Note Because there is only one pod selection, the Connect tab in the Emulator Configuration window is informational only. The Hdw Config tab offers options you can select or clear. However, when you load your program a dynamic change to the selected items can occur if programmed with these selections. The debugger is configured and operated by the Seehau IP2K user interface. Seehau is a high-level language user interface that allows you to perform many useful tasks, for example: Loading Flash RAM, running, and stopping programs based on the open source GNUpro C- compiler and linker platform (not supplied by Nohau Corporation). The GNUPro tools and documentation for programming the IP2022 processor are available from Red Hat. This special version of the assembler outputs in ELF format specifically for the Nohau debugger. Contact Nohau Technical Support if you have questions. Modifying and viewing memory contents including general-purpose registers. Setting one hardware breakpoint and multiple software breakpoints that can be placed in RAM or Flash. Edition 1, July 2001, Nohau Corporation 1

Chapter 1. Overview of the EMUL IP2K PC Emulator System 2 Preliminary EMUL IP2K PC User Guide

EMUL IP2K PC User Guide Installing the EMUL IP2K PC/USB JTAG USB Driver When installing the USB device, you must install the Seehau software first before connecting the Nohau hardware (Refer to Chapter 3, Installing the Seehau Software. ). This allows the computer to recognize the proper driver for the hardware. The USB option is not supported by Windows NT. The USB drivers are loaded when the Seehau software is installed. The driver is located in the root directory of the installation CD. After installation, the driver is also located in the Seehau IP2K subdirectory on your hard drive (C:\Nohau\SeehauIP2K\). The system software should find and load the USB driver without your intervention. If your system does not find the driver, it should prompt you for the path if the software does not find the driver on the CD. Power Supply The EMUL IP2K PC/USB JTAG uses power supplied by the USB cable and the target board. The amount of power used by the??? from the target board is less than 100 µa. When drawing power from the taget board, the??? must draw from a 2.3V to 3.6V range. The power supplied by the target board drives the signal from the buffer on the??? through the BERG connector to the target board. The??? draws power from the target board through Pin 9 (Vdd). Figure 1. EMUL IP2K PC/USB JTAG Edition 1, July 2001, Nohau Corporation 3

Chapter 2. Installing the EMUL IP2K PC/USB JTAG Note The EMUL IP2K-PC/USB JTAG is a dual power???. For the dual power to initialize correctly the Ubicom target board has a three-pin jumper (JP24) which must have pins +3.3 and TOOL selected (IN). The following table shows the signal layout of the connector: Pin Name Description 1 KEY Key 2 /TSS Target slave select 3 GND Ground 4 TSCK Target data clock 5 OSC Target clock oscillator 6 Reserved Reserved 7 /SRST System reset 8 TSI Target serial input 9 Vdd Power 10 TSO Target serial output Installation Instructions Refer to Figure 2 for a diagram of the connectors while following the installation instructions. 1. Make sure your target is powered off. 2. Plug the 10-pin EMUL IP2K PC/USB JTAG BERG connector into your target s pro-gramming interface. This connector, supplies the signals needed to communicate with the EMUL IP2K PC/USB JTAG. 3. Power on your target. Note Exit Seehau and shut down the power to the target when the target is not in use. In addition to the red wire indicating the number one wire, the BERG connector has the hole for the number one pin plugged to ensure the correct connection. Also, pin one on the demo board is missing. 4 Preliminary EMUL IP2K PC User Guide

EMUL IP2K PC User Guide Hardware Configuration Tab Note Only Mask Interrupt on Step is a debugger configuration parameter. The rest are chip configuration parameters stored in the configuration block. The initial configuration settings are read from the Startup.bas file when the debugger initializes. These are default values and should not be changed. If a program, containing new settings for the FUSE registers is loaded, the Hdw Config tab is updated with the new values. After the initial startup and configuration of Seehau, the configuration parameters are saved in the Startup.bas file (located in the Macro subdirectory). The next time the emulator is started, the configuration parameters are read in from the Startup.bas file and compared with the default parameters on the chip. If the parameters on the chip and the file are different, you will be prompted by a message box to load the application program for the configuration parameters to be sent to the chip. If you want to load the default chip parameters, select the CFG button on the Speedbar after loading the Startup.bas file. You can also choose to upload the current configuration parameters from the chip at any time using the Speedbar (CFG) button. If you save the settings after loading the parameters from the chip, these settings will become the default values on the next startup. If configuration parameters using Config menu items (Config/Emulator) are changed, you will be prompted to load a program (load code) for the new parameters to be loaded into the chip. Note When you load code the current configuration parameters change to the values read from the code file. These new parameters are then programmed to the IP2K chip. The following values for the chip are currently used: Processor: Shown for reference only. This is the selected processor. Clock(MHz): Shown for reference only. Enables you to change the clock speed.

Multiple Breakpoints in Flash: This option is connected with the Always Use Bulk Erase option. To use this option, you need the newer version of the processor. Software breakpoints work by the break instruction. Software is executed until it hits the first break. When you program load the software into RAM there is little concern. You can place these breakpoints throughout your program, remove them and replace them. In Flash, you do not normally want to do this because you have to erase the Flash each time and the number of times you can do this is limited. If this option is checked then the Flash will Edition 1, July 2001, Nohau Corporation 17

Chapter 4. Configuring the Seehau Software be handled just as if it is RAM except that it has to be erased each time it is loaded.

The Pre Parameter field contains command line parameters to the compiler that appear before the file name Test.c. The Post Parameter field specifies command line parameters that appear after the file name Test.c. The Output File filename is Test.obj. The Report File filename is Test.lst. If the file settings are specified for the linker command file, the Output File name is Test.omf or Test.hex and the Load Into Seehau option should be selected. This instructs Seehau to load the linked output file into the emulator. Building a Project Building a Single Project 1. Select (highlight) the project. 2.
