the TWR-MPC8309 processor module can be operated as a stand-alone single board computer (sbc), a primary elevator connected system- on-module (som) or a tower system rapid prototyping development platform. freescales mqx? software support enables applications to quickly migrate from freescale microcontrollers up to the high- performance mpc8309 processor featuring industrial connectivity and a protocol off-load engine which eliminates the need for an external industrial protocol fpga/asic in the system. pre-loaded software ? u-boot bootloader ? freescale linux ? os with real-time patches ? freescale mqx real-time os ? mpc8309 mcu control interface api ? diagnostic routines to validate board functionality TWR-MPC8309 net-p23345-TWR-MPC8309-o1v6.indd 3 11/4/11 5:19 pm
4 connect a display (optional) purchase the mpc830x-tlcd display module to remove the need for a host computer. the display is driven with a 16-bit big-endian parallel interface. powering TWR-MPC8309 connect the usb2 full-speed port to host computer usb port(s) using the provided usb cable to power the board, which also establishes a console connection to the host. alternatively, power can be supplied over the usb2 high-speed port or the twr-elev connection. finally, a power adaptor (not included) can supply power over the 5-volt ( ) jack. configuring a terminal application for the console on-board circuitry has been provided to support a host computer con sole window over the usb2 full-speed port. upon power-up, the host computer should recognize new hardware named twr- mpc8309_virtualcom, which should be configured with the TWR-MPC8309_ virtualcom.inf driver included on the dvd or available at freescale.com/twr- mpc8309 . once the virtual com port is configured, display the console using any terminal emulation application attached to the com port with the following serial protocol settings: bits per second: 115200, data bits: 8, parity: none, stop bits: 1, flow control: none . see the user manual for more details. step-by-step installation instructions in this quick start guide, you will learn how to set up the TWR-MPC8309 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/TWR-MPC8309 . 1 2 3 quick start guide net-p23345-TWR-MPC8309-o1v6.indd 4 11/4/11 5:19 pm
tower system 5 view informational demo upon power-up, the board automatically boots the freescale linux os running an informational demo showing a jpeg slideshow on a connected display or text files in the host computer console window. see the user manual for details on how to modify the demo contents. entering the boot configuration and diagnostic menus the booting behavior can be changed by entering the boot configuration menus. with a host computer connected to the usb2 full-speed port (see step 3), hold down any key on the host computer while the board is booting. select the desired boot configuration using the menus in the console window. diagnostic routines have been included to verify the functionality of the board and can be run using the diag command in u-boot. see the user manual for details. 4 5 net-p23345-TWR-MPC8309-o1v6.indd 5 11/4/11 5:19 pm
6 connecting cables dual ethernet and rs485 ports enable point-to-point networking demos on a single TWR-MPC8309 module. any ethernet cable can be connected between the ethernet ports and the ports will auto-configure for proper communication. auto-configure also enables a direct connection from either ethernet port to a host computer ethernet port. an rs485 loopback cable has been included which can be connected between the two rs485 headers. line up pin 1 marked with an arrow on the cable connector to the header pin 1 on both rs485 ports. all TWR-MPC8309 headers have pin 1 marked with a white dot printed on the board and increasing pin numbers proceeding top to bottom, right to left from pin 1 while looking into the header pins. debugger interface connections connect the desired debugger hardware to the standard jtag/cop header lining up pin 1 with the obsel configure switch setting in the off position. twr- mpc8309 includes on-board debugging circuitry to support an osjtag debugger library. to use osjtag connect the host computer to the usb2 full-speed port and set the obsel configure switch setting to the on position. configuration switch settings see configuration switch settings on the following page. 6 7 8 quick start guide net-p23345-TWR-MPC8309-o1v6.indd 6 11/4/11 5:19 pm
