Hi there,<br><br>I'm using the Canyonlands evaluation board for the ppc 460ex processor. I want to access the GPIO pins, set its direction and set/get their values.<br>Is there is any common driver to do so? I went throught the Documentation/gpio.txt and the arch/powerpc/sysdev/ppc4xx_gpio.c but I don't know <br>how to test the later driver either from kernel space or from user space. Any ideas or sample codes?<br><br>Thanks in advance.<br><br>Musaab.<br> </body>
