hi all,
I'm working with the ML300 platform running the shipped Montavista Linux
(and hw configuration). I need to use the onboard gpio and I found a driv=
er,
the xilinx_gpio, that I have loaded (insmod xilinx_gpio). After insmoding=
the driver it is registered in /dev/xgpio (why is not it loaded in /proc/=
before?) I have tried to use the GPIOs...
cat "111111000000" > /dev/xgpio
I was expecting some leds lighting but nothing at all...
Is there someone experienced with the ml300 gpios?
Please I need help
Luigi

You must use ioctl's.
This driver has the same API as IBM OCP GPIO driver.
Please check include/linux/ibm_ocp_gpio.h.
Thanks,
Andrei
