User GPIO Interface

The CoreModule 430 provides GPIO pins for customer use, and the signals are routed to header J8. An

example of how to use the GPIO pins resides in the Miscellaneous Source Code Examples on the

CoreModule 430 Support Software QuickDrive.

The example program can be built by using the make.bat file. This produces a 16-bit DOS executable

application, gpio.exe, which can be run on the CoreModule 430 to demonstrate the use of GPIO pins. For

more information about the GPIO pin operation, refer to the Programming Manual for the Vortex processor

at:

http://www.vortex86sx.com/

Table 3-12 describes the pin signals of the GPIO interface, which uses a 10-pin header with 2 rows, odd/

even sequence (1, 2), and 0.079" (2mm) pitch.

Note: The shaded table cells denote ground.

Oops! Jumper (BIOS Recovery)

The Oops! jumper is provided in the event you have selected BIOS settings that prevent you from booting

the system. By using the Oops! jumper you can stop the current BIOS settings in the CMOS from being

loaded, allowing you to proceed, using the default settings. Connect the DTR pin to the RI pin on Serial port

1 (COM 1) prior to boot up to prevent the present BIOS settings from loading. After booting with the Oops!

jumper in place, remove the Oops! jumper and go into the BIOS Setup Utility. Change the desired BIOS

settings, or select the default settings, and save changes before rebooting the system.

To convert a standard DB9 connector to an Oops! jumper, short together the DTR (4) and RI (9) pins on the

rear of the connector as shown in Figure 3-2 on the Serial Port 1 DB9 connector.
