2 quick start guide get to know the TWR-PXS3020 TWR-PXS3020 freescale tower system the TWR-PXS3020 module is part of the freescale tower system, a modular development platform that enables rapid prototyping and tool re-use through reconfigurable hardware. elevate your design to the next level by building your tower system today. potentiometer (0C5v) general purpose tower plug-in (twrpi) socket flexcan rs485 user leds adc user buttons (e.g. interrupts) primary connector ethernet mii to twr-elev reset button nexus samtec jtag mddr 256 mb osjtag secondary connector
3 tower system ? high-performance 180 mhz e200z7 dual cores ? dual processing spheres, including: cpu, dma, interrupt controller, crossbar and mpu ? two statically configurable modes of operation: lockstep operation (redundant processing and calculations) and dual parallel mode (independent core operation) ? fault collection unit monitors and manages fault events ? error correction coding on ram and flash memory allows detection/correction of memory errors safeassure program: functional safety. simplified. freescales safeassure functional safety program is designed to help system manufacturers more easily achieve system compliance with functional safety standards: international standards organization (iso) 26262 and international electrotechnical commission (iec) 61508. the program highlights freescale solutions hardware and softwarethat are optimally designed to support functional safety implementations and come with a rich set of enablement collateral. for more information, visit freescale.com/safeassure TWR-PXS3020 features
4 in this quick start guide, you will learn how to set up the TWR-PXS3020 module and run the included demonstration software. for more detailed information, please see the user manual found on the included dvd or at freescale.com/tower. quick start guide step-by-step installation instructions connecting twr-ser insert the TWR-PXS3020 and twr-ser boards into the primary and secondary elevator board. the primary and secondary card edges for each module are indicated along the card edges. powering twr-px3020 connect the TWR-PXS3020 board to a computer or a wall charger using the provided usb cable. additionally, the usb connector on the primary elevator can be used to power up the board. using the serial to usb bridge the freescale mc9s08jm60 serial to usb bridge solution provides a rs-232 equivalent connection to the host computer through the usb communications device class. when plugged in and powered, the usb connection will enumerate as a com port on the pc. this means any terminal utility program may be used to receive serial data from the usb port. to determine the com port number for the connection, right click on the my computer icon and select manage, click device manager, find and expand ports (com and lpt). 1 3 2 note: for windows xp 64 bit users, please refer to the pxs30 serial communications options document at freescale.com/twr-pxs30.
5 tower system installing the software driver when the cable is plugged in for the first time, the found new hardware wizard will start. select the option install the software automatically and the driver will be installed automatically. the cdc virtual serial port is also available on the dvd or at freescale.com/twr-pxs30 . configuring a communication terminal open microsoft hyperterminal or a terminal program of your choice. create a new connection and use the com port from step 4. use the following settings: ? bits per second: 115200 ? data bits: 8 ? parity: none ? stop bit: 1 ? flow control: none running demonstration code press the reset button on the board and follow the output information on the terminal screen. the installed program will display example outputs from the device and allow you to interact with the user buttons and board leds. 4 6 5 ? mqx? real-time os ? green hills software multi ide ? serial bootloader utility ? codewarrior v10.x eclipse development studio ? osjtag virtual serial port using usb ? rapid application initialization and documentation tool (rappid) ? freemaster run-time debugging tool additional software and tools
