6.3i EDK - GPIO v2.00.a software driver fails in Linux

Description

Keywords: SetDataDirection, DiscreteRead, DiscreteWrite, xpgio.c

Urgency: Standard

General Description:
Running MontaVista Linux with the Xilinx GPIO driver v2.00.a results in an error. With the addition of dual channel support for the driver, the API for functions in xgpio.c such as XGpio_SetDataDirection(), XGpio_DiscreteRead() and XGpio_DiscreteWrite() were changed and these changes cause the current MontaVista Linux 3.1's GPIO adapter source code to fail.

Solution

This problem has been fixed in the latest 7.1i EDK Service Pack available at:
http://support.xilinx.com/xlnx/xil_sw_updates_home.jsp
The first service pack containing the fix is 7.1i EDK Service Pack 2.
