5 NXSB100 - NetX StarterKitBoard Description 5 1 Description 1.1 Introduction netx Technology The netx is a highly integrated network controller with a new system architecture optimized for communication and maximum data throughput. Based on the 32-Bit CPU ARM 926EJ-S clocked with 200 MHz, it provides a memory management unit, caches, DSP and Java extensions. Together with 32 Kbytes ROM holding the Bootloader and a Real-Time kernel, the internal memory of 144 Kbytes RAM is sufficient for smaller applications. The connection to a primary host is accomplished by the dual-port memory mode of the host interface, which is also configurable as a 16 Bit extension bus for stand-alone applications. Comprehensive peripheral functions, serial interfaces such as UARTs, USB, SPI and I²C provide a wide spectrum of applications. Yet, it is the central data switch and the four freely configurable communication channels with their own intelligence that are the main characteristics of the netx as a "high end network controller. Figure 1: netx Block Diagramm

6 NXSB100 - NetX StarterKitBoard Description 6 The data switch interconnects the ARM CPU, communication and Host controllers, memory blocks and peripheral units via five data paths. This allows the controllers to transmit their data in parallel, contrary to the traditional sequential architecture with only one common data bus and additional bus arbitration cycles. The controllers of the four communication channels are structured on two levels and are identical to each other. They consist of dedicated ALUs and special logic units that receive their protocol functions via Microcode, combining the performance of dedicated (single-) protocol controllers with the flexibility of a CPU. Two of these channels can further be linked to integrated PHYs for Ethernet communication. The Medium-Access-Controller xmac sends or receives the serial data stream according to the respective bus access process and encrypts or converts these into Bytes. The Protocol Execution Controller xpec compiles these into data packets and controls the telegram traffic, accomplished by DMA transfers. In addition, every channel has a Dual-port-memory available for status information or as local data image. By its intelligent communication ALUs, the netx can implement the most varied protocols and protocol combinations and can synchronize them independently of the CPU response time an absolutely new feature in industrial communication technology NXSB 100 Starter Board The NXSB 100 is a low cost and yet extensive Evaluation- and Development platform for the netx Chip. It is equipped with 4MB of serial Flash and 8MB SDRAM. Further, the board provides two 100Mbit Ethernet Ports for Real-time Ethernet communication, PROFIBUS-Slave and DeviceNet interfaces. As standard communication ports the user will find one RS-232 serial port, as well as an USB (1.1. full speed) port which operates as Device.. The host interface can be configured as dual-port memory, extension bus or general I/Os and is available through a 64 pin header. All elements of the board are powered by an onboard switching power supply, which can be powered by a wide range of simple (unregulated) standard power supplies from 9V to 24V output voltage. For software development, all NXSB100 boards come with a standard JTAG connector, allowing to connect an appropriate debugger device. NOTE: Like all Hilscher starterboards, also the NXSB 100 uses simplified circuits (no galvanic isolation) for its physical fieldbus interfaces and is also in no way optimized in terms of EMC compatibility. This product is intended to be used for evaluation and development purposes in lab environments only and is not suitable for production use!

Depending on the corresponding status register of the netx, this LED can either show yellow (RDY= 0, RUN=1) or green (RDY=1, RUN=0) colour. If both pins are low or high, the LED will be off. When the board is in Bootstart mode (see chapter 2.2.2) The yellow SYS LED will flash with a frequency of 1Hz. The Digital Output LEDs O1, O2, O3 and O4 can be turned on and off by controlling the appropriate GPIOs (see table 11, above) Fieldbus Status LEDs The MNS and COM Dual LEDs are intended to provide fieldbus status information for the DeviceNet (MNS) and the PROFIBUS interface (COM). They are controlled by PIOs 4,5,6 and 7 (see table 1)

10 NXSB100 - NetX StarterKitBoard Display and Control Elements Buttons Reset Button Boot Button The NXSB100 is equipped with an onboard reset generator, providing a proper Power On Reset signal to the netx. This circuit will also issue a reset, in case the voltage from the onboard 3,3V power supply should drop below appr. 2,9V -3V. Additionally, the netx can be manually reset by pushbutton: The reset button (labeled RESET ) will also activate the Power On Reset signal (signal remains active until button is released). While a true Power On Reset also activates the JTAG-Reset signal applied to the netx100 (Pin U17), the reset controlled by RESET, only activates the PORn signal. This Button is used to enter the serial bootmode of the netx. To activate the serial bootmode, press the Boot Button and the Reset Button, then release the Reset Button while still holding the Boot Button. Now the Boot Button can be released. The yellow SYS LED on the NDSB-100 should now flash with a frequency of 1Hz, indicating the netx is in serial bootmode. Activating the serial bootmode skips any firmware stored in a non-volatile memory connected to the netx and allows firmware download through UART0 or the USB interface (an appropriate software tool (netx Bootwizard, see chapter 4.2) is available for free from the Hilscher website or may be found on your product CD) Input Buttons The NXSB-100 provides four pushbuttons (I1, I2, I3 and I4), which connect to GPIO12, 13, 14 and 15 of the netx. When one of these buttons is pressed, the corresponding GPIO pin is pulled to high level. 2.3 Jumpers - the current revision of the NXSB100 does not provide any configuration jumpers -

11 NXSB100 - NetX StarterKitBoard Connectors 11 3 Connectors 3.1 Power Supply The NXSB 100 can be operated by a DC power supply from 9V 24V which is to be plugged into the power jack X100 located in the lower right corner of the board. As the input circuit provides a bridge rectifier, the polarity of the power plug does not matter, however an AC supply shall not be used, as the input capacitors are not sufficient for that mode of operation. The current drawn by the NXSB 100 depends on several factors such as operating mode of the netx, CPU load, use of additional hardware and mainly on the level of the input voltage (the higher the voltage, the lower the current). For standard operation of the board, the power supply that comes with your NXSB 100 is sufficient. If additional hardware is being powered by the NXSB 100, the use of a stronger supply may be required. Pin Description 1 Ground V Table 2: Power Supply, X100 GND 24V Figure 4: Power Supply, X100

For more information on how to get a full license, refer to the How to get a License chapter of the HiTOP Licensing Procedure. Click at the following button: Enter the startup script you would like to load. Use the Browse... buttons to search for the startup script.. Figure 20: Startup Script Selection

27 NXSB100 - NetX StarterKitBoard Software Tools 27 Click Next Tool Settings Select the compiler tool chain you are using from the list box ( GNU C Compiler for ARM ). After selecing a supported compiler tool chain, the Tool Settings Button appears, allowing you to modify the tool settings. Figure 21: Project Settings The most important settings are the tool path and the names of the assembler, compiler and linker executables. NOTE: The tool path is a global setting that applies to all projects which use this tool chain! Figure 22: Default Linker Settings On the bottom of the dialog the Assembler, Compiler and Linker tabs allow to adjust default settings for the tools. The default settings are used when creating a new build configuration and although they are global settings, modifying them has no effect on existing build configurations in existing projects.

28 NXSB100 - NetX StarterKitBoard Software Tools 28 The next step is to enter a new application. Click at the New button and enter the desired application name in the new line that now appears in the application window. Now close the dialog box by clicking the OK button and reopen it through the the Project > Settings menu (this step is vital, as you won t be able to edit any settings without it!) Figure 23: Applications Build Configuration The build configuration for the current project can be modified by selecting the project in the Project Settings dialog and the selecting the Tool Settings button. Figure 24: General Settings

29 NXSB100 - NetX StarterKitBoard Software Tools 29 However, before being able to modify the configuration, it has to be created first. A new build configuration can be derived from the default settings or from an existing build configuration. Users may want to use several build configurations to let them work with different settings or compiler options (debug and release version of the binary). To create a new configuration, klick on the New Button and enter a name for the build configuration. If other configurations already exist, they can be selected as templates from the drop down menu, otherwise only <none> can be selected, which leads to the use of the default parameters for the new configuration. Figure 25: General Settings Figure 26: New Build Configuration

30 NXSB100 - NetX StarterKitBoard Software Tools 30 Once the configuration is created, it can be adapted through the four tabs (General, Assembler, Compiler, Linker) as shown below: Figure 27: Linker Settings The linker dialog allows defining a linker command line, a linker script file and a post build step. Users should be aware, that HiTOP currently doesn t generate a file list which is provided to the linker. The user has to take care that all files which are part of the project are listed in a file, provided to the linker. It is also possible to provide a file list as command line parameter. However, this is only recommended for simple projects with a small number of linked files. For large projects the command line length may exceed the maximum length if too much files must be linked together.

32 NXSB100 - NetX StarterKitBoard Software Tools netx Bootwizard You can download the latest Boot Wizard Version from our homepage ( netx > Downloads > netx Design Information, Documentation, Examples and Tools > Software). The netx Boot Wizard is a graphical front-end for the generating and processing of netx boot images. The wizard s primary use is to create bootable binary images from compiler output, like elf files, and write these images to the netx SPI flash memory. Further it offers functions to check and modify boot images, extract data and parameters from compiler output and generate standalone boot blocks. This manual describes version 0.7. Please note that this version is a prerelease. Functions and their graphical representation are subject to change in later releases. This chapter only provides short form information on the netx Boot Wizard main functions. Please also consult the full documentation included with the Boot Wizard files Startup The netx Boot Wizard starts with a simple dialog. The text field shows the output log of the wizard. The screenshot shows the welcome message including version information. Figure 28: netx Boot Wizard start screen In the current version the main window only offers the button "Run Wizard", which enters the boot wizard dialog when selected. The boot wizard dialog then starts with a short introduction to the tool.

33 NXSB100 - NetX StarterKitBoard Software Tools 33 Figure 29: netx Boot Wizard dialog Click Next. Figure 30: the operation mode menu The function dialog now lets you select the action the wizard should perform. The first two items in the menu are described in the following chapters. Click Next.

34 NXSB100 - NetX StarterKitBoard Software Tools Function build bootimage This function generates a boot image (a boot block with appended application data). The application data is extracted from a compiler output file, like an elf image. The dialog starts with the selection of the input file. Figure 31: Build Bootimage, Input file Selection Click Next. The following dialog prompts for the source and destination devices and the toolset. The source device specifies the device that will hold the bootimage (parallel or serial flash).
